I just recently setup a very simple home recording studio after picking up drums again at 40. I had the same thoughts, but I'm going it for me and it is extremely therapeutic. Plus, given the genre (extreme metal), I've gotten into much better shape. (Also picked up an 8 string guitar. I never grew out of my edgelordiness. No real point to mentioning this but just wanted to tell someone :)

AI music may eventually satisfy the masses and you can't stop that speeding train, but the process of creating something yourself will always have value if it's something you're interested in creating.
