No they don't, look at music popular in social networks.

Even before the generative AI, I think we live in the era where there are more creators than ever in history: everybody today can publish their music or art without any large investments (except for instruments: they are expensive as always). I would prefer we have cheaper pianos, samples and microphones instead of worthless music-copying models.

Pianos are already cheap. You can get used pianos for very little money if you shop around. No one has space to keep a piano in their house anymore, and they don't want to deal with keeping them tuned.

There are lots of ML models that produce instrumentals and vocals that are incredibly useful for practicing musicians.

The popular and well-known Suno and Udio are pop culture toys. They also find use with content creators who don't have time to learn how to make music. (Not everyone can learn and master everything. We have to let some of our creative desires slip or we'd never be able to accomplish anything.)
