I've heard some scary numbers when it comes to waste, but I don't have a source, nor do I intend to go digging for one because I'm already depressed enough. But you addressed neither of my other grievances. In the end I'd just prefer a future where work is automated, and not creativity nor thinking. I will speak up in this small space where I might be heard, when I believe corporations are betting on getting people hooked on AI because they've never learned to think or bothered to create for themselves, just so they can extract massive profits.
By all means, keep investing and being interested in specialized AI, AI research and AI ethics. But stay away from generative (text/image/video) AI.
