>Not sure how they can expect to make a viable full OS without massive use of LLMs, so this makes no sense.

Humans have been doing this for the better parts of 5 decades now. Don't assume others rely on LLMs as much as you do.

>Not to mention that even finding good developers willing to develop without AI (a significant handicap, even more so for coding things like an OS that are well represented in LLM training) seems difficult nowadays, especially if they aren't paying them.

I highly doubt that. In fact, I'd take a significant pay cut to move to a company that doesn't use LLMs, if I were forced to use them in my current job.
