I've seen that before. Re-reading it, I don't really get the same "vibe" as antirez's level of AI advocacy. You also conveniently omitted the last paragraph of the tweet:

> Will there be more or less game developer jobs? That is an open question. It could go the way of farming, where labor saving technology allow a tiny fraction of the previous workforce to satisfy everyone, or it could be like social media, where creative entrepreneurship has flourished at many different scales. Regardless, “don’t use power tools because they take people’s jobs” is not a winning strategy.

But yeah, it (almost) sounds like an ad for AI, but I like to believe it's still a measured somewhat neutral stance. The difference is that Carmack doesn't consistently post things like this unprompted, unlike antirez.
