In a software house with 1000+ developer, we're using AI everywhere. We have plenty of skilled engineers to validate the output of LLMs, but instead of spending 3 weeks developing a new feature, they can now spend a couple of hours or days.
We absolutely still need skill engineers for keeping track of what goes on, but their productivity has skyrocketed when they no longer have to obsess over details for a long time.
It is terrifying that any working software developer believes this is true.
LLMs are useful tools. But regardless of your inputs they guarantee nothing, ever.
