You're being downvoted because you appear to be not asking genuinely and you're trying to cast doubt instead of seeking to understand.

Because at this point there's really no excuse for not having any idea why people are mad about AI. If you can't guess it's because you're intentionally ignorant of the problem. Because "just asking" is a specific strategy used do doubt and discredit anyone you disagree with.

Not the person you asked, but my nephews and mentees (all under 18), very plainly see it as the destruction of their own future careers (regardless of field), assimilation of everything meaningful humans have ever created into a copy machine , massive privacy violations, wrecking the environment and generally run by some of the biggest sociopaths in human history. When looking at it practically over the last few years, I think a lot of younger folk don’t see any upsides.

I’m very pro-AI myself, but think the kids are quite right in their perspective, and that the tech companies designing and pushing this tech are in for a bad time when this wave finally comes crashing down on them.

And I'm frequently amazed how tone deaf tech people are and how disconnected from the general population. ;)
