It was a reply to what the GP said about running local generation 24/7 for no good reason, just because it's possible (and electricity is too cheap, apparently). There are many more threats, but those are beside the point in this specific context.

Obviously "useful" doesn't just involve making money. Code that will be used for education and all of these things is clearly not useless.

But let's be honest to ourselves, the sort of useless code the GP meant will never ever be used for any of that. The code will never leave their personal storage. In that sense it's about as valuable for the society at large as the combined exabytes of GenAI smut that people have been filling their drives with by running their 4090s 24/7.

At least you (hopefully) get hours of entertainment from firing up an AAA game. Whereas generating vast amounts of code that you're never going to use has… some novelty value, I suppose. Luckily the novelty is going to wear off soon, I can't really see many people getting their daily happiness boost from making code machine say brrrrt straight to /dev/null. Even generating smut is a vastly more understandable (and vastly more commonplace, even now) use case for running genAI every day for hours.
