Sounds quite normal, honestly. Programming is in a dark place right now relative to how I used to enjoy it. I haven't touched a personal project in many months. You did something for four decades and whatever mystery may have been left there is probably gone with AI.

Try identifying what made it feel like a "passion." Was it problem solving and discovering new things on your own by piecing things together? Then yeah, AI probably has something to do with that in regard to software development - but there are many other avenues you can take to fulfill that whether it be unrelated hobbies or charity work, etc.
