The idea that creating music has had a huge technical barrier is laughable. It has not existed for ~20 years. Artists like Tinashe have learned to produce music themselves with programs like ableton, not a lick of mastering instruments or graduating from this and that art school. Just a general sense of what sounds good to you. Unlike visual art, there's no mechanical barrier either, no mastering of techniques. You can genuinely fiddle around with knobs and buttons and create something that sounds great to you - soundcloud is filled with these.
So there isn't going to be an increased level of profound self expressions because of this. Quite the opposite, more pure noise for the purpose of farming ad revenue.
What's worse, and an aspect many proponents of AI generations ignore, is that by ushering people into this specific channel of caring more about prompts than all else, we are doing a real disservice to potential people who could have become serious masters of their realm. After all, "why learn how that music program works when I can just generate it?"
