I once went to go pick up takeout and they covered the no tip button with a sticker. I was so confused so I put in 10 cents because I could find the button at first. I stopped going to the place since.

Pushing Dan Ammann out was a bad idea. I personally like the original set up at the time. Kyle as the CTO and Dan as the CEO. Kyle was great as an internal CEO, he was calling most of the internal shots anyway. The accident would have played out very differently if Dan Ammann was the CEO IMO.

(Also former Cruise employee)


Was always unclear to me whether DanA was truly pushed out, or if the board (largely comprised of GM execs) wanted to take the company in a different direction than Dan wanted to go, and Dan decided to leave rather than stick around. Ie. IPO vs keep it a majority owned subsidiary.

I got the impression that it was a conflict with Mary Barra specifically, not so much the board as a whole. They simply went along with her. The tone of the notice was indicative of being pushed out, not a mutual parting of ways.

Why a Twitter post and not the official Google blog post… https://blog.google/innovation-and-ai/models-and-research/ge...

Just normal randomness I suppose. I've put that URL at the top now, and included the submitted URL in the top text.

The official blog post was submitted earlier (https://news.ycombinator.com/item?id=46990637), but somehow this story ranked up quickly on the homepage.

@dang will often replace the post url & merge comments

HN guidelines prefer the original source over social posts linking to it.


Agreed - blog post is more appropriate than a twitter post

Wow that was a fun read, I never thought about the technical implementation of these verification systems.

Tim Dettmers had an interesting take on this [1]. Fundamentally, the philosophy is different.

>China’s philosophy is different. They believe model capabilities do not matter as much as application. What matters is how you use AI.

When you have export restrictions what do you expect them to say?

> They believe model capabilities do not matter as much as application.

Tell me their tone when their hardware can match up.

It doesn't matter because they can't make it matter (yet).


Sorry, but that's an exceptionally unimpressive article. The crux of his thesis is:

>The main flaw is that this idea treats intelligence as purely abstract and not grounded in physical reality. To improve any system, you need resources. And even if a superintelligence uses these resources more effectively than humans to improve itself, it is still bound by the scaling of improvements I mentioned before — linear improvements need exponential resources. Diminishing returns can be avoided by switching to more independent problems – like adding one-off features to GPUs – but these quickly hit their own diminishing returns.

Literally everyone already knows the problems with scaling compute and data. This is not a deep insight. His assertion that we can't keep scaling GPUs is apparently not being taken seriously by _anyone_ else.


Was more mentioning the article about the economic aspect of China vs US in terms of AI.

While I do understand your sentiment, it might be worth noting the author is the author of bitandbytes. Which is one of the first library with quantization methods built in and was(?) one of the most used inference engines. I’m pretty sure transformers from HF still uses this as the Python to CUDA framework


There are startups in this space getting funded as we speak: https://olix.com/blog/compute-manifesto

Scale. You can monetize on the people that don’t pay the $200/month. Obviously I have nothing to prove this statement, but I wouldn’t be surprised if the subscriptions are loss leaders.

Sam Altman said they are losing money on their $200/m tier.

Not OP but I doubt it. I’m in my mid 30s and when I grew up there in the 90s, Suffolk county was bumble. Some people had horses on their land. After 9/11, a ton of people moved in from the city and the population absolutely ballooned. Over two decades, the population grew so much that just Nassau county and Suffolk county combined has more people than a handful of states. People come and go too (including myself) so unless some organization is tracking us, it’ll be hard to pinpoint.

Aha likewise, I swear, between the ticks and the polluted water, a good amount of us are screwed. Grumman has put some nasty stuff into the ground too. I remember growing up how they mentioned it was slowly seeping into the aquifer. Took me ages to convince my parents to get a RO machine

I worked at BNL during college days through the SULI program! Some of my peers from college is working there full time now too. I got to work on some really cool stuff but unfortunately a lot of the tenured researcher I knew have seem to left. I heard a lot of researchers left during Trump’s first term.

I know there’s metal plates you can self stamp for crypto wallets. I’m sure you can do the same for this purpose.
