ChatGPT is one of the most used websites in the world. Compared to e.g. Facebook you are not "forced" to use it (because of friends or whatnot) so it's all voluntary usage. There is real demand for AI usage, that's why RAM and GPU prices are skyrocketing, not because of some evil conspiracy.
I don't see this, no. I think HN serves as a sort of Rorschach test for the reader. I get a center-libertarian vibe from HN, definitely not left wing. That's probably my own biased perception, of course.
