The concern is for value though. Like, if I'm going to use a massive amount of power and water to compute, I should be considering value to humanity as a whole.
AI is being sold as that, but so far, it's actually harming instead of helping. Supercomputing was helping pretty much right away.
I suppose you could argue that if general supercomputing was invented now, it would be used for just as superficial uses. Maybe the context of personal computing, the internet, and corpo interests shape that.
