Feels like this is a byproduct of a poor work-life balance more than an intrinsic issue with programming itself. I also can't really relate since I've always enjoyed discussing challenging problems with colleagues.

I'm assuming by "die" you mean some future where autonomous agentic models handle all the work. In this world, where you can delete your entire programming staff and have a single PM who tells the models what features to implement next, where do you imagine you fit in?

I just hope for your sake that you have a fallback set of viable skills to survive in this theoretical future.
