I think you mean:

yes (the environmental angle is a complete distraction and red herring from moving towards more sustainable energy production generally; the ethical one is just plain nonsense spread by people with absolutely no idea how these things work)

yes (people use and like them, people have fun with them and create great art with them. You might not but that's a you problem)

and ... well actually probably no tbh (but that's a problem with capitalism not technology).

Stop making shit up to dismiss new technology because you're a luddite

The answer to all these questions is actually yes but sure invent absurd conspiracy throes if you want to feel smart or whatever, you're literally the same as the antivaxxers and 5gphobes but whatever i guess, if it makes you feel superior.
