I'm not sure how much overlap there is between the "everyone's just a consumer these days! That's awful, they should be creators!" set of posters, and the "needing fewer people to do anything at all is always a good thing, bring on the glorious AI future!" set, but I suspect it's at least non-zero and I find that rather confusing.

Yes, let's make it so anything short of world-class creative talent (if that, even, if "AI" keeps advancing) is something that's of no monetary or social value, then wonder why people don't spend more time creating stuff. You're not motivated to play violin in your bedroom for nobody, or make paintings to hang in your own closet because nobody wants them? Or, there's no need for you to build this kind of great thing for your elderly relative because an AGI can do it instead? And now you're a couch potato struggling with depression and wondering what the point of living even is? Quelle surprise!

It's as if solipsistic intrinsic motivation is shit compared to having others want or need what you can do for them, and like maybe we need the latter in order to be healthy. But no, let's race toward further reducing our value to others as fast as we can, what could go wrong?
