I think you're overlooking the fact that for long-horizon tasks, even small errors compound over time and can lead to catastrophic outcomes.

For simple queries, we have reached the threshold since the beginning of the year, and models are good enough from every provider to make a meaningful difference between one another. (ChatGPT, Claude, Gemini, Grok, MuseSpark, Kimi, DeepSeek, GLM...)

The real unlock will be, and you can already see it with GPT-5.6 and Fable-5, to delegate complex enough tasks that will take more than 24 hours to get done and they will not lose track. I'm not talking about a loop, but the actual intelligence to recover from these compounding errors that accumulate in dumber models.

We're still a long way from the intelligence needed to let one of these agents go ahead and supervise multiple layers of sub-agents underneath to do complex orchestration. The future looks very promising and exciting. Imagine having the possibility of a Frontier model orchestrating as many sub-agents as needed that are running on cheaper models like DeepSeek.


That doesn’t make sense. It’s not like SOTA models are error free, yet we still use them.

You use Fable 5 right? If that’s good enough for you now, why wouldn’t a Chinese model that’s as good as Fable 5 but at 10% the cost be good enough in 6 months?


I think we put up with Fable's occasional hiccups because there's nothing better at the moment.

I use Claude Code semi-heavily for my small business, and the $100/mo I pay for that is a rounding error compared to the value it provides.

If I can avoid spending an hour or two "massaging" the output from a lower-end model once, or it avoids introducing one load-bearing (sorry, couldn't resist) bug, then that's the entire $100 right there.

Hell, you could argue that the best "coding model" that we have at the moment is the human brain, and people will gladly pay $10,000/mo for one of them.

Arguing over $20 vs $100 for something that actually puts in work just seems insane to me.


> I think we put up with Fable's occasional hiccups because there's nothing better at the moment.

Which was an argument for using every less powerful model since the moment they got useful, right?

When was that? Opus 4.5 maybe? Let's say Opus 4.5 for the sake of the argument. So back then we were like "DeepSeek is not good enough, I need Opus 4.5". Now DeepSeek is better than Opus 4.5. So if Opus 4.5 was good enough back then, DeepSeek is better than that now.

Sure, it's always nicer to have a slightly better model. But the price difference starts mattering a lot more when all the models are already sufficiently good.


To put actual numbers on it, since using AI to start solving all kinds of bottlenecks/inefficiencies in our small business, we've seen monthly net profit go up by around $4,000 USD. These are semi-permanent fixes, and the tech is only partially deployed. I am the only one using it, and I only use it part time.

We've just spun up our first Hermes agent, with direct API access to our main inventory system and that's expected to find another few grand per month in misallocation/inefficiency.

I wouldn't be surprised if we were doing more like $10k/mo higher in 6-9 months' time.

When you're talking about numbers like this, the fact that one AI is $100/mo and another is $10/mo or $40/mo doesn't matter. They could make GLM-5.2, or any other Opus 4.5-class model free and it still wouldn't make sense to deploy in a commercial context.

The other angle I'd approach things from is that Opus 4.5 (and I'd agree with you that that model was the saddle point) was "good enough" for the types of things we were asking it to do back then, but as the models have become more capable the tasks we're asking them to do have also expanded with it.

I know I've personally gone from "hey can fix this race condition with a Redis mutex" 6 months ago to "Independently redesign this full embedded USB stack and QA it end-to-end, working around a specific Kernel bug in macOS Tahoe that requires decompilation to find the source of, while keeping in mind the constraints of our 8-bit AVR chip from 2011" now.

But that said, yes, maybe in 5 years' time we will reach an "intelligence saturation" where the average person won't be able to even conceive of how to use the new SOTA.


I think we're even starting to reach that saturation point now for a lot of people. In my industry (law) plenty of people have tried CoPilot once or twice, or tried ChatGPT a year ago, and as a result have basically dismissed AI as being useless. The setup required to be able to get it to do end to end tasks to your liking is also substantially more work than most people are willing to put in.


I find 500x returns on my $20 Chat GPT and Claude subscriptions as I litigate pro se against large law firms in federal court.


Case numbers? I'd love to take a look at the dockets.


I think HN doesn't really understand fixed costs, I spend a few hundred dollars per day on Fable and the costs are irrelevant compared to what we make.


I've never understood this line of thinking...

Are you saying we shouldn't care about the future of affordability and access because at this moment we have seemingly endless access?

Sounds extremely short sighted.


No, its that going from $2k/mo to $20/mo is not worth the capability loss in the slightest, because AI just isn't a big part of our fixed costs.


"оur first Hermes agent, with direct API access to our main inventory system" – let me assure you that absolutely nothing can go wrong here, mate. /s


Don't you think that's a bit of an inane comment to make about a setup you know nothing about?

Surely they are using read-only access.


We are obviously limiting access to be read-only for anything customer-facing (it will be able to put recommendations in the dashboard but not actually change things directly) but I think the point of GP's comment was literally just to get a reaction.


Did you mean to post this on Reddit instead of HN?


I get what you were trying to say, but the quality difference is actually extremely low.


When you do things in life, sometimes things go wrong. Oh no!

This is such a ridiculous objection for how beloved it is. Wide swathes of the public can't cope with any adversity or risk.


No, the point is that with human in the loop the downside is (usually!) rather limited, as common sense would stop obvious fuckups (ok, not always, but still).

With an agent (especially incompetently employed), the danger of unwittingly destroying your company (or at least, the crucial data/reputation) is rather higher. We are notoriously bad at estimating the downside risks in complex systems.

The most obvious case is the downside risks in complex financial constructs... things look great for a while ... until a sudden surprising collapse arrives and totally destroys all the upside you think you have created.


There is a tradeoff to be considered between the utility gained from using the stuff, minus the risk severity/likelihood, plus available mitigations. As someone else posted, none of us are in a position to make that balanced post because we don't know if the guy has an airgapped backup or not etc.

In any case, GP's post was not such a balanced consideration; it was just parroting a beloved risk-aversion meme that can easily be deployed against building anything (what if the building falls on top of someone?) or even leaving home to go to work ("travelling in a hunk of steel at lethal speeds – let me assure you that absolutely nothing can go wrong here, mate.")

What I find tiresome about that meme is the presumption that "something can go wrong" is useful input on its own. It's not. Mistakes are made all the time, the only way to avoid that is to stop breathing. Even in the process of me standing up and going to the loo, something can go wrong.

If the guy wants to make a case that it's too dangerous for the expected benefits, he has to actually make that case. Saying "risk exists" with no elaboration is a waste of HTML. "something can go wrong" every time he swallows food, yet mysteriously he still does it.

(the suicide analogies may seem mean-spirited, but I kind of mean it. If you consider every action primarily from a standpoint of "what harm or irreversible change can result from this", the only permissible path is to do nothing. To be moral is to be as close as possible to a rock or another inanimate object.)


An agent will read your comment and take it as a challenge to show something can go wrong. Thanks for prompt injecting, mate. /s


The question low cost models will create: Why would you massage output?

Fable 5 is still going to mess things up at any sufficient complexity. The advantage of low cost models with "good enough" intelligence is they can recursively correct. Why? Because it is cheap. Proper requirements and tests and subagents take away increasing amounts of work, at a cost that is not prohibitive.

If you are reviewing code manually you might consider Fable 5 a worse option. As it articulates itself with higher confidence and you already know it is capable, you are may be more likely to miss a mistake. You know to be on guard with a junior engineer. Reviewing a senior who suddenly makes some weird stochastic mistake can be a lot harder. It would be like if the smartest human engineer you knew was capable of some random brainfart in the middle of their massive diff. Imo, much harder to deal with.

Of course, we should keep in mind Fable 5 is only expensive today. It will be cheaper in the future. Autonomous, recursive prompting and improvement is the clear end state. Especially for entities that will always have the budget for that at the SOTA frontier.


Except Fable won’t be costing $100 for enterprises that will be considering the Chinese models.

If $100 Claud Max subscription works for you, then great.

But you have to remember your pricing is subsidized by enterprises that pay hundreds of thousands of dollars each month, if not more, to Anthropic.

For those companies, a Chinese model that can cut their AI spend from $1M/month to $200k suddenly seems attractive.

And unfortunately for the American tech industry, the valuation is based off those enterprise deals, not your $100/month Claude Max subscription.


Didn’t deepseek recently announce prices will go up significantly?

Right now the US dominates everyone else in actual chips in data centers. So even if deepseek etc tries to undercut, they’re very capacity limited.


It's far from significant, it's partially doubled during peak hours. They could 16x it and it would still be two orders of magnitude better value than OAI's $200/mo plan.

It's that good. They are far from capacity limited, and even if they were, you can rent a single MI300X from somewhere like Hot Aisle and get more tk/s than you'll be able to use.


How does it compare to 5.6 Luna after the permanent 80% price cut?

That one is dirt cheap at API pricing, I can't imagine quota is going to be a concern on the $200 subscription, which in my opinion easily supports full time use of 5.6 Sol on xhigh.


It's still laughable. They blew it. I'm not sure they could even pay me to use their models at this point (and I don't mean via employment, meta and its refugees are permabanned to me). My experience over the past few months with open models has me seriously entertaining moving east.

A couple of very talented friends were uttering curses upon the entire bloodline of whoever convinced them to try letting sol xhigh do serious work. Deepseek cleaned it up for a fraction of $20.


Since you did not compare them, I now checked myself, and it looks like Luna benchmarks about the same as DeepSeek V4 Flash 0731.

The cost per task was $0.03 with DeepSeek, $0.05 with Luna. $1.23 for Sol.

Tokens per second 132, 202, 70 respectively.


> Didn’t deepseek recently announce prices will go up significantly?

They also previously said prices will go down significantly once they get a hold of the upcoming Huawei chips (later this year).

Prices are going up just because they can. It can easily come back down. They aren't strained by some IPO / VCs requiring them to 1000x their earnings.


Deepseek is open weight/source ie it will be running on US servers in the US maybe by on each companies own servers.


I don’t think the industry knows how to price this stuff. Deepseek is great (I’m running it on a RTX 6000 pro setup) but it’s nothing like Fable. It’s still strongly human-in-the-loop which is fine, until you experience how good these models can be.

Think about it this way.

Let’s say you could buy an LLM that gets things right 98% of the time. But there’s another LLM that’s 100x the price but gets things right 99.9% of the time. To the lay person this sounds trivial but to a serious business this intelligence gap could represent millions, or billions of dollars.


If that’s the case businesses would be seeing millions to billions of profit gain (or cost reduction) in the past 4 months as they went from Opus 4.6 to Fable 5.

But that’s simply not the case. It’s very clear that vast majority of the business do not generate additional value from incremental intelligence gain from these models.

There is a reason why Chinese open weight models are now popular even in American enterprises, because CTOs realize that they are indeed good enough.


I work for a FAANG, and have my own personal projects for which I use the Chinese models. and the big models do indeed save/make us a lot of money.

The Chinese models are not good enough for anything other than pair programming, which is just a very last-gen way of using agents.

And when the big US models get better we will move with them. Until we stop seeing returns there is no "good enough", I don't know why this is so hard for HN to understand.


> just a very last-gen way of using agents.

Fable has only been out for a month but somehow everyone is supposed to have moved to a completely different way of working that supposedly only works for Fable and nothing else…


This stuff is just obvious to anyone working with the latest models. Fully autonomous agents are a game changer. Having to pair program with one is indeed "last gen", I haven't done that for a month and I won't ever be doing that again in my life, outside of personal projects.


> This stuff is just obvious to anyone working with the latest models. Fully autonomous agents are a game changer.

This kind of takes makes me cringe. Why don't you go back to LinkedIn?

I have no idea what you mean by “pair program with an agent”, but Opus have been able of autonomous coding since last November, and with any half-decent harness even local Qwen3.5 was able to do so 6 months ago.

Fable is a stronger model, which means it can solve harder tasks but it's also over-hyped, because only a small fraction of task is hard enough to be Fable-worthy.


I use Kimi K3, Opus 5, and Fable on a daily basis.

Fable is the only one that reliably one shots complex changes and makes the right design choices. Everything else requires handholding.

I can let Fable loose on a 12+ hour (for AI) task and it will have performed it flawlessly when I come back the next day. K3 and Opus are not like this.

And no, our harness is not the limiting factor here.


> This kind of takes makes me cringe. Why don't you go back to LinkedIn?

This is not appropriate for HN. Please review the guidelines: https://news.ycombinator.com/newsguidelines.html


It depends on the use case. And most companies (like 90%+) do not have the coffers FAANG has and price does make a big difference.


Unless you are very cash strapped, Fable is a very nominal fixed cost compared to the benefit of what it offers (fully autonomous agents, and no longer needing to pair program with one).

And even it isn't "enough". I can very clearly see myself using more advanced agents to move up the abstraction ladder.

For businesses that have actual problems to solve, I see them investing in the frontier for a good bit longer, probably until we have AGI that can replace employees, maybe even a bit after.

This is why I find the "good enough" arguments silly. Like, the usefulness of an AI tops out to you when you can pair program with it? Seriously? You cannot envision ways in which more advanced AI enables you to do more, better? That's bizarre to me. I don't ever see myself running out of problems to solve.


> [...] probably until we have AGI that can replace employees, maybe even a bit after.

Is this what you are looking forward to?


>I don't know why this is so hard for HN to understand.

There are businesses other than FAANG. I don't know why this is so hard for FAANG employees to understand.


I use Chinese models, even smaller local ones, for much more than pair programming. If we are talking about deepseek v4 flash, which is basically a frontier model, it is much more capable than the local models I run on my MacBook Pro. The only issue really is finding the right harness.

I do have a way of correcting through redundancy, though. If you are just vibe coding, you need to use the most capable model you can find and even then it might not be good enough.


> If you are just vibe coding, you need to use the most capable model you can find and even then it might not be good enough

I mean, this proves my point. Better models enable you to get more done. With Fable, 80% of the time, I no longer have chat with an agent over the details of a PR. I give it an outcome and it gets done. This means I can work on much more with the limited time I have.

And I don't see this ending. When better models come out that take that from 80% to 99.x%, I will have that better model manage teams of other models and move up the abstraction layer.

If models get even better than that, perhaps I stop reviewing PRs entirely. Maybe normies can start using agents to build real things.

Unless your business doesn't have many problems to solve and isn't in a competitive environment, it will benefit from using the best models.


If you don’t have a way to automatically check the results via redundancy, you need a really good model, since even 99.9% reliability is going to cause slot of headaches. If you do have a way to automatically check results, then you can use something that fits in your computer and was produced 3 years ago.

My point is you don’t need the best model if you just put in QA processes that can be done by models also. And if you don’t have that, the model is probably not going to be good enough.


> The Chinese models are not good enough for anything other than pair programming, which is just a very last-gen way of using agents.

This matches my experience with DeepSeek V4 Pro at Max reasoning, the preview version of the model kept regularly messing things up. About 30-60% of additional time to fix the output was needed.

On similar tasks, GLM 5.2 at Max reasoning screwed up maybe 20-30% of the time, while it still definitely made noticeable mistakes, they were far fewer in total and less egregious.

Kimi K3 at Max reasoning drops that value to below 10%, it's about as good as Opus or approaches Fable in some tasks. At High reasoning it also seems to be pretty close to Opus 4.8, not sure about the latest Opus model yet, but it's up there.

Only problem is that K3 is nowhere near as cheap as DeepSeek models, despite me personally liking the writing tone more (less Anthropic slop) and finding that it doesn't block my cybersecurity prompts, recently reproduced SQLi with a proof of context so I could justify fixing it.

My overall thoughts (released over some time):

https://blog.kronis.dev/blog/kimi-k3-is-out-is-anthropic-don...

https://blog.kronis.dev/blog/z-ai-s-glm-5-2-is-a-great-model...

I'd say as Chinese models get better, whatever moat Anthropic and OpenAI have dissipates. Currently the main things keeping me with Anthropic are their performance (tokens/second) and the fact that their visualization abilities within the app are pretty good.


> This matches my experience with DeepSeek V4 Pro at Max reasoning,

That was ages ago (in LLM release timelines). DeepSeek V4 Flash beats it now and a lot cheaper.

> On similar tasks, GLM 5.2 at Max reasoning screwed up maybe 20-30% of the time,

GLM 5.3 bridges this gap.

> I'd say as Chinese models get better, whatever moat Anthropic and OpenAI have dissipates.

Their moat, especially OpenAI is funding and hardware resources. They gain train models 10x as large and also serve at large scale. That's it.


> GLM 5.3 bridges this gap.

I’m sure the next models will only get better, when they’re released. Also super curious about what Moonshot will achieve and the full DeepSeek V4 Pro release!

> Their moat, especially OpenAI is funding and hardware resources. They gain train models 10x as large and also serve at large scale. That's it.

I’ve seen how much slower Kimi K3 can be and that part seems correct, their own GPU production still has ways to go and export restrictions definitely limit what they can do.

Not sure about the size part, if Kimi K3 achieves SOTA performance at 2.8T parameters, western models being >2x that size would be insanely bad in regards to efficiency. I bet they’re all within the same order of magnitude and below 10T and won’t really have a reason to go even that high for the foreseeable future.

As investors will start squeezing them for profitability, I suspect focusing more on efficiency will be commonplace.

They're a lot larger e.g. Fable. It is insanely bad. Do you know how much more resources "Western" companies have? Most in China don't have random GPUs to "play with" like every "frontier lab" employee does.

> As investors will start squeezing them for profitability, I suspect focusing more on efficiency will be commonplace.

They're born lucky though. Efficiency is "free". The next generation hardware e.g. Nvidia claims Blackwell -> Rubin is 10x efficiency (verified by Neoclouds apparently).


> It’s very clear that vast majority of the business do not generate additional value from incremental intelligence gain from these models.

It's been 2 months since Fable was released to the general, man. Nobody knows what's going on inside of these companies except the people at the coal face.


> but it’s nothing like Fable. It’s still strongly human-in-the-loop which is fine,

It's funny to see that Anthopic shills have been saying the exact same thing for the past two years now (and it was OpenAI fans before). It's amazing to see that Claude 3 Sonnet was "great" but now that even Qwen 9B is better than this version of Sonnet DeepSeek V4 is still not good enough despite being stronger than Opus 4.7 was.

> Let’s say you could buy an LLM that gets things right 98% of the time. But there’s another LLM that’s 100x the price but gets things right 99.9% of the time

If you think Fable makes 20 times fewer mistakes than DS4 you're delusional. It doesn't even do 20 fewer mistake than Gemma 4…


> not your $100/month..

This is made brutally obvious by anthropics customer support for people with such accounts.


Yeah, fair. If we were talking $2,000/mo vs $200 then the maths starts looking very different.


The discussion started about cost-vs-usability, and then you brought in "but humans, the best LLMs around, cost much more" into this discussion to make it a not cost-vs-usability discussion. Do you not find it a bit disingenuous?


Not really, no. My point is that a $100/mo LLM subscription is generating $5000/mo in value, so even a negligible difference in performance wipes out the cost savings completely.

Same reason it makes sense to assign a team of humans that cost $100k/mo to a product that brings in $5M/mo, rather than one human with 5 Claude Max subs.

The cost is a rounding error.


> You use Fable 5 right? If that’s good enough for you now, why wouldn’t a Chinese model that’s as good as Fable 5 but at 10% the cost be good enough in 6 months?

This is why I quite like Kimi K3 - close to the same performance (definitely like Opus, approaching Fable), noticeably cheaper, generally good enough for me to daily drive. Only problem is that their official provider (on the Vivace plan) feels kinda slow, I'd say close to 2x slower than Opus on Max reasoning on average (probably more relatable than Fable).


SOTA models are exceedingly good at self-correction in the right harness especially in domains where things can be proven mathematically. Most people are just deploying Claude Code or Codex with default settings and rub the genie lamp expecting exceptional results. Garbage in, garbage out.


"isn't the old version good enough?"

"It's only real AI if it comes from the silicon region of USA"


There are a lot of tasks that are hard for organisations to run consistently but require some intelligence - monitoring logs and metrics for anomalies and security events, backup audits, audit processes in general, ensuring document quality and consistency, database advice and tuning, customer experience management, process optimisation - that are not "long horizon" in the classical sense of each step depending on the last, but are the result of consistency and attention over a long period of time and a large amount of data.

For this genre of task execution can run with limited horizon and is independent but would be too expensive to do with "us frontier tokens", I think for these, there is value in availability of cheaper tokens.


These are not 24 hours of inference with floating point errors accumulating; largely the system guards against errors compounding. Tool failures, compile failures, test failures, etc, push back against the model taking a wrong turn and force it to correct.

Yes it's much easier to have a smarter model that goes straight to the correct answer first, but it may not be necessary or economical. There's a minimum bar for the model where it understands problems and knows the right step to correct them, and above that newer models give diminishing returns.


> it's much easier to have a smarter model that goes straight to the correct answer first

That's basically ASI not AGI, if you agree humans are NGI (natural general intelligence) and make mistakes and wrong decisions in solutions all the time. Right steps with some wrong ones is acceptable though for AGI.


> these compounding errors that accumulate in dumber models

While SOTAs handle these errors better, they compound in all models and there's a term for that. It starts with cluster and ends with an expletive.

I wish I could, but I don't see the need for human steering going away soon if the task involves anything novel (see Terry Tao's chat).


What you're overlooking is that any large task can, and should, be broken down into smaller individual components that can be reasoned about and tested in isolation. This is literally the whole basis for how we do programming. You don't need a model that can keep track on a gargantuan tasks all at once. You need a process for breaking problems down into manageable chunks, and then assembling them into a solution. This is a problem that can be solved by a harness through steering and and having a decent agentic loop.


Majority of white collar work absolutely does not require sota models


White collar work will require SOTA models up until the point where said models can automate white collar work entirely. Then, we might finally see a meaningful commoditization crunch.


I genuinely don't know any work that has been taken over completely by AI without humans in the loop managing things

At this point, I don't even know if its possible


I have a silly (but honest) question. What's an example or two of a > 24hr task that people are actually asking something to do? Like real life ones.


Decompiling / disassembling and annotating old software, making sure it can build cleanly back to the original binary, and then look for bugs or subtle issues.

Another one I did was a printer data stream translator from an obscure format to PostScript/PDF (or just PNGs), complete with cups support, etc so these old apps can easily be hooked up.

Flash is capable now of running long range defined-goal tasks like this.


Working through the total backlog of issues in a repo that may have accumulated from planning sessions


I wondered this too. Also, the duration of the task depends on the quality of the prompt and the model used. I have a feeling a lot of these day-long tasks are bogged down by suboptimal tool use and on-demand python slop.


Amazing how many inaccuracies you fit in there.

- You describe the breakdown in terms of time but it's more accurately a function of reasoning complexity.

- You seem to assume that no intermediate evaluation is possible.

- Often it is (e.g. the build breaks or tests start failing), allowing for course correction. There's definitely a cost to that but it can still be cost effective if the accuracy is "good enough" and the price difference significant.

- There are numerous tasks that don't require Fable or GPT5.6 level reasoning to improve efficiency by an order of magnitude.


> even small errors compound over time and can lead to catastrophic outcomes

So, death sentence even to frontier models?


Very interesting and I would also love to export my own data! Care to share/elaborate a little further how you went into doing this, especially with platforms that do not offer the option to export your own data.


“Nuclear fusion is 30 years away; and always will be." I wonder how this phrase manages to hold after 50 years since its inception.

We could compare it to the state of general AI, but at least in the machine learning field, progress is being made without knowing the feasibility or path to reaching general in AI. In fusion it appears that the theory has already been set and maintaining the chain reaction going for long enough is the limitation (progress being made here), would it be the same case that the final steps are still missing without a clear path, or would the current progress be enough to eventually reach it?


AI research has made slow scientific progress but great engineering progress. Fusion has made great scientific progress but still has a lot of engineering left to do.


> has made great scientific progress but still has a lot of engineering left to do

It’s made serious engineering progress too.


Engineering work halted 30+ years ago. There has been no recent work on structural materials that could withstand the neutron bombardment, and no work on extracting bred tritium at parts per billion concentration from thousands of tons of "blanket" material needed for the next day's operation.

There is no possibility of any present scheme operating at even 10x the cost of fission. Fission is not today competitive, and falls further behind each day.


> Engineering work halted 30+ years ago. There has been no recent work on structural materials that could withstand the neutron bombardment

We've made massive strides compacting designs, thereby transforming their unit-economic envelope, using low-temperature superconducting magnets. Those magnets continue to improve, driving potential gains in designs faster than experiments can be funded and built. Optimizing for structural materials, or even blanket versus replaceable structure, seems premature when we don't know the parameters or even type of bombardment we'd be working with.


Bombardment is with hot neutrons.

Period.


You can get around the tritium problem with boron-proton fusion. Also gets around the inefficiency of converting to heat / turbines. Obviously not any closer to production (and probably further) than tritium fusion, though. https://hb11.energy/how-it-works/


There is no reason to expect that p-11B fusion is possible.

It might be, in a hundred years, if our present understanding is wrong, and somebody figures out how to reflect gamma rays.


It's been done by firing lasers at a HB pellet, so I assume you mean not possible to be done commercially? And why would you have to reflect gamma rays?


Are you talking about the company H11B?

Their scheme has been soundly criticized in the literature as not working by a factor of ~100.


Obviously you can fuse about anything by accelerating nuclei at each other fast enough. If it takes more energy to do it than you can get back, it is of purely academic interest. Firing lasers comes up many orders of magnitude short.

Another alternative is magnetic confinement, but radiative loss goes up with the 4th power of temperature, so would be 10000 times as much as for a D-T plasma, IIUC.


This chart rests upon faulty assumptions about the efficacy of tokamaks, but it does demonstrate how little interest the U.S. federal government has had towards research of fusion.

From what I've seen living a privileged community in a not so privileged country, its that culture tends to impact in a much higher degree than money or privilege. Yes, money can buy you the privilege of skipping those awkward interactions that make us human, but it is up to the person to actually want to use money with that purpose.

I know very wealthy people that keep very closed ties to their families and friends. It's true that finding real friends gets harder, but the isolation tends to be caused by a deeper cultural norm.

E.g. in Latin America the family is given a much higher importance than in the States or Europe. It is not rare to see young adults living with their parents even if they can easily afford a place of their own. Even those that live on their own tend to meet their families in a regular basis.

In the end it's all about prioritizing what is important in your life and in every society there seems to be a common list shared by it's inhabitants, if you end up in a place that values more independence than relations, maybe its time to start swimming against the current in that regard.


Well, that's true, but my argument is that cultural norms spring from necessity. In places where a lot of people must live adjacent, that kind of living becomes the cultural norm and even if you're in a position to do your own thing, you are still influenced by it.

That is, cultural norms affect people, but basic necessity also affect cultural norms. Just like your values inform what you do, but what you do also changes your values.

You're right in that we must make greater efforts to swim against the current, but so many of us must in adulthood develop tools to foster community and connection. That's hard to do, especially when you're vulnerable, there's trial-and-error involved and you don't really have a good model for what you "should" be doing.


I have a hunch than in a couple decades this issue will be amplified. The biggest problem we are seeing from the disposal of more social interactions arises from not giving it its true importance.

It may be as you say that in the past interactions were fostered mainly as a side product of the necessity to cooperate and interact with others. However as we develop and become for independent thanks to prosperity and technology we must not get rid of interaction for they are an end in itself.

The issue or even taboo is the lack of importance that is given to the interactions with others just for its own sake. Maybe we will move on from this need and become more self reliant, however in the short term it seems that we are having a hard time adapting, especially with the increase of suicides and drug use in younger generations. -> https://news.ycombinator.com/item?id=21650584


>in Latin America the family is given a much higher importance than in the States or Europe

I'm brazilian. I have a sister who is married to an american, and they live in the U.S. He always jokes how my sister talks to our mother in Brazil 10x more than he talks to his, yet his mother lives 15 minutes away.


The study mentioned is "Just think: The challenges of the disengaged mind" https://science.sciencemag.org/content/345/6192/75

>Next, participants received our standard instructions to entertain themselves with their thoughts (in this case for 15 min). If they wanted, they learned, they could receive an electric shock again during the thinking period by pressing a button. We went to some length to explain that the primary goal was to entertain themselves with their thoughts and that the decision to receive a shock was entirely up to them. Many participants elected to receive negative stimulation over no stimulation—especially men: 67% of men (12 of 18) gave themselves at least one shock during the thinking period [range = 0 to 4 shocks, mean (M) = 1.47, SD = 1.46, not including one outlier who administered 190 shocks to himself], compared to 25% of women (6 of 24; range = 0 to 9 shocks, M = 1.00, SD = 2.32).

You can read the complete study here, https://wjh-www.harvard.edu/~dtg/WILSON%20ET%20AL%202014.pdf

I´m quite intrigued about the outlier who managed to shock himself every 4.7 seconds for 15 minutes straight. Was he trying to go for a record or just plain masochism...


Thanks for finding this, was it linked in the article and I just missed it?

Either way, I was wondering if people shocked themselves out of curiosity, but the part after what you quoted says "Note that these results only include participants who had reported that they would pay to avoid being shocked again... But what is striking is that simply being alone with their own thoughts for 15 min was apparently so aversive that it drove many participants to self-administer an electric shock that they had earlier said they would pay to avoid." They all already knew what it would feel like and they did it anyway.


No, it was not properly referenced in the article. I had previously seen the study.

From the supplementary material:

> All participants delivered the shock to themselves in this first part of the study. Thus, in Part 2 of the study, when people had the opportunity to shock themselves again, everyone knew what the shock entailed and how painful it was.

They also asked the participants to rate the experience from the sock in a 1-10 scale (negative to positive) and removed all participants who didn't find the shock as a negative experience.

The grade the remaining participants gave to the shock experience was in the lowest part of the scale, which makes it even more insane:

> ratings of the shock, t(52) = 1.40, p = .167


It's too bad studies like this have errors (obvious only in retrospect). I learned as a kid to entertain myself with thoughts and can do so easily for a long time.

But I will shock myself at least once just to see how bad the shock is... not because I would be bored.

(unless they took this into account and let everyone shock themselves before starting the experiment? That would be smart of them... didn't have time to read the study)


I wondered about the same, see my sibling comment. They all had been shocked and had said they'd pay to not be shocked again.


I am you and you are me! I have to reign in the day dreaming or I can sit on a bench happy in my mind for hours. I too would have to shock myself at least once to assuage my curiosity.


> "Ensuring the safety of associates in our building is our number one priority and we invest heavily in safety,"

Having pain medications on vending machines for their employees seems to me like scheduling to fix a leak after it rains.


The innovators dilemma talks about a similar situation with storage. Every x years a new, smaller format would arrive and everybody would brush it aside until after some time the benefits would be noticeable and everybody would scramble to jump into the new format.

This process would go on to repeat itself, not always the innovators of introducing a new format would be able to replicate this shift, mainly because they would be victims of their own success and had to keep up with expected revenue and margins.


Capitalism has its perks, great advancements have been made in technology, quality of life and the development of cities that would otherwise have never existed.

The real issue lies when you look at the system in a more holistic, long term view, lets say another 200 years. In that time-frame the self propelling cycle of capital will make the accumulation of all wealth lie in a very small group.

In itself it is not a bad thing as long as advancements are still being made and the average quality of life is improved, however it leaves the system with a very centralized point of control.

This point of control could quickly deviate the system for purposes not entirely in the best interest of the species, put it as "Power tends to corrupt, and absolute power corrupts absolutely." It may be a possibility but not the great peril. The real issue lies in the central group having accumulated all resources, and then not being able to maintain said resources and leaving the whole system open to a single point of failure by a revolt of some sorts. (starting from scratch can take more energy that the energy required to topple the system, and sometimes there may not enough energy to build over...)

Do we really want to have a society were the integrity of it depends on a single point? Maybe we do, but it just might not end up being the most resilient system.


I recently came up with an article that promoted an "innovative" park, buzzwords aside, it seems like a great project that is ongoing in Istambul, Turkey.

The Parkorman park looks amazing: https://www.archdaily.com/868082/drors-parkorman-park-in-ist...
