I'm not near retirement, but I have found that the side projects I work on have diminished quite a bit since AI took over coding. It used to be that writing a library for something like parsing ICal files was something I could spend time on, write, build out, and then other people could use. But now anyone can throw together a working version of it in a little bit. That's a good thing, but also it removes the fun of spending the time implementing it and creating something for others.
