More fundamental question: if everyone can generate an album in an afternoon, why would anyone else listen to any of those? It turns into dust in the long tail.
IMO, because it's good in a way or another. I'm not reading your writing because I imagine you toiled over every word of it, but simply because I started reading and it seemed worthwhile to read the rest.
Or, to use a different metaphor, these comments are mentally nutritional Doritos, not a nicely prepared restaurant meal. If your restaurant only serves Dorito-level food, I won't go there even if I do consume chips quite often at home.
LLMs will accelerate the pace of this assimilation. New trends and new things will become popular and generic so fast that we'll have to get really inventive to stay ahead of the curve.
Basically most of it is all noise but eventually something blows ahead of the curve and shines for a couple of seconds before the curve/wave catches up and engulfs it again.
Most of what "goes" ahead of the "curve" is achievements of other people. You, I, and most other people are just watching other exceptional or lucky individuals shine for a couple of seconds. We are all watchers. There's no difference from our perspective if the people we are watching are humans or AI. It's not us anyway.
If you are an exceptional genius who regularly achieves things that go past the "curve" then you will be affected. You will watch AI achieve things faster than you, do better than you, etc. In this case you are affected.
Keep in mind that this "curve" I talk about is both global and has many many localized instances. Like a superstar at a start up is a localized example of an individual blowing past a localized curve, and Einstein is a global example of an individual excelling past a global curve.
