I am in my 50s. I agree with what others have said about your happy place. For me, it is not APIs and fine details of operator overloading. I love solving problems. So much so that I hope I never retire. Tools like Claude Code give me wings.
The need for assembly programmers diminished over the decades. A similar thing will happen here.
Or retire and realize the beach forever is not your version of retirement, and get back to it. I spent a week in the Philippines on the beach before getting bored of that and pulling out a laptop and digging into some Linux thing with Claude code, and then now I'm torn between which app to work on to launch.
