People are not excited because those companies blatantly disgregard the law, exploit and fuck people over and try to concentrate as much power as possible in their hands. Young people are not stupid, they can see that the increasing wealth gap makes their lives suck more. And they also understand that AI is a hypercapitalistic tool, that, if left unchecked, will only accelerate this trend.
So yes, that kind of curbs the enthusiasm, doesn't it?
