So in your scenario above, AI is the torture, and taking a plane flight is murder. Hm. If those are equvilent in your head, I think you have issues. But let’s play your game.
If the purge night were real, and it was common place to murder people all night long. Then a person who only tied people up and say tickled them relentlessly (which is torture) but released them at the end of the night alive would in fact be better than someone who murdered. Now of course you say, but someone who didn’t even torture would be better. Yes absolutley. But in the real scenario talking about damaging the environment, everyone is damaging it. So there is no option to choose the no damage doing person. That leaves you with choosing the better of two evils. So a person who stays home and uses AI does less damage then one who takes a flight. Yet you can only focus on the AI case. So much you can’t see anything else. Thus you can’t see the forest because of the trees.
