There's this trend in the last couple of years of very successful software engineers heartily endorsing AI usage - I can think of Matz, dhh, Linus, uncle Bob. Probably a lot of other people I don't follow too closely.
I can't pinpoint a common motivation for all of them, other than the obvious (the tools are great and are the future, if you think otherwise you're a loser (paraphrasing dhh) etc).
I think at least at some level, these people are at a point of their careers where they have "been there, done that" (coding) and are happy to go do something else.
All of them have in common not having written code in a long time, instead reviewing patches from others, so the AI thing isn't really too different from what they've been doing for a long time.
Here's Linus' diatribe if you haven't seen it - https://lkml.org/lkml/2026/10/13/3242
