You could say that gaming is also bad for the environment and that’s just entertainment. But I wouldn’t say that we should get rid of it. Both cryptocurrency and AI have uses to our society. So do computers, internet, etc. All that technology has a cost, but it is useful. Technology also usually keeps improving. For example Etherum doesn’t require mining anymore like Bitcoin does, so it should require much less electricity. People always work on finding new solutions to problems.

A human being writing stuff only uses as much energy as a human being doing just about anything else, though.

But if a computer the size of a smartphone could do the work of multiple people, that might be more efficient and could result in less coal being burned.

Computers and automation have improved our lives and I think AI might too. If AI takes away my job, but it also improves the society, would it be ethical for me to protest against it? I think it wouldn’t. I’ve accepted that it might happen and if it does, I will just have to learn something new.
