AI is good for some industries, but destroying others like you were talking about with stock photos. At one point, that was a decent little side hustle, but yeah, not anymore. That's done. Between AI and Canva, which now has AI built in is killing those industries.
I also used to make a good living doing mixing and mastering for artists, but AI is killing that too. I am still a purist at heart though with music and AI still can't do what a human can do. I have heard allot of the AI music stuff and it's just not there yet, but will be eventually.
What I do use AI for is mainly giving me post ideas and then I go back and have it help me proof read and basically be my editor.
