Alright, but why would I actually spend time to actively listen to it? Op was specifically talking about Classic music being replaced by AI in listening events, not about staying on hold on a phone calls or waiting on a parking spot.

You wouldn't actively listening, and that's why generated muzak would be okay. "The acoustic equivalent of a screensaver", as someone in the thread called it. The idea that classical performances would be replace human composers in concert context is quite ridiculous. Maybe as a novelty, once, but that's all.
