I think this is a very valid point, but thinking about it, it's not what bothers me most. I know I can make music that AI likely will never be able to make.
Perhaps it's more related with getting attention. There's likely musicians who don't seek attention too much. But I guess most musicians want to be heard. Why do so many musicians upload their works to Spotify, well knowing that they never will make money there. It's their hope of getting attention.
Getting attention, also on the small scale, always has been difficult. Many musicians don't enjoy booking gigs, because it's hard and consists primarily of rejection.
On the listener side, it's even harder to cut through the masses, and today's online world has in effect trashed the noughties' promise that the Internet will make things possible for all of us.
And then comes this AI prompter dude and all his co-dudes are like: Oh your song is so great, I love it.
So, basically yes, it's a different twist of what you wrote already.
