Maybe we will lose low effort artists but gain great music by passionate people.

You'll never be able to find it or hear it though. The barrier to entry for AI music is so low, even lower then the "low-effort" artist you are deriding, that typical streaming sites will be inundated by it and nothing else will be found. The algorithm(tm) already prefers low-royalty music, and AI music will certainly have the lowest costs to play.
