> I'm trying to learn music production with a DAW, sometimes I wonder if I'm wasting my time. Part of my reason for trying this was reading how creative endeavors can be therapeutic (I'm dealing with burnout/depression/cptsd).

If you enjoy the process and its outcomes, then it's not a waste of time. If you are forcing yourself to do it or have another motivation for it that is not rooted in genuine interest, then yes, you are wasting your time.

> I feel like AI is making this question of "why do it" or "what is worth doing" even more urgent

This is a spiritual question, so you will have as many answers as there are askers. I found my answer and am happy to share it with you. Why do it? Because I want to. What is worth doing? What I want to do or what gets me to the things I want. Wanting is a very important process, that is often damaged by conditioning. We are told that some things we want are bad and that some things we don't want are good. Or that ego is evil. So many ways this process can go wrong. I think fixing this in oneself is part of becoming an actual adult. Once you know what you want and what you don't want, you no longer are dependent on others telling you what to do or forcing you to do things you shouldn't be doing. Ego is not evil, it's there for a reason. Some people have an overgrown one while others have an underdeveloped one. What is needed is balance. I don't think the pattern recognition machine has anything to do with it. I suspect, that a lot of people who use music as a band aid for personal problems, i.e. people who build their identity around being special due to music making, are the ones who are afraid of AI, but if you just enjoy making music, then what does it matter if music itself is patterned and if a machine can exploit that? It doesn't take anything away from the joy of making music, if you experience it in the first place.
