>This isn't chess or go, where you either win or you don't. Chopin composed for a reason, and it wasn't just an excuse to throw a lot of notes at the page.

I disagree based on your following quote:

> Aside from that, this still sounds like aimless noodling. It's far more polished noodling with some awareness of genre cliches, but it's still essentially aimless - and so meaningless.

This sort of problem can easily be reframed as a win or lose problem, we simply consider whether the music sounds good or not. More concretely: would this music be able to convince you that a gifted human composer created it?

I'm fine with the answer being no, but I don't understand why the original comment I replied to wrote off the entire exercise. No we may not be there yet, but this seems like a good step forward to me.
