One time when I was in the Unix computer lab in college, testing my C skills on a Sun workstation, an old lady sat down at the workstation next to me. She must've been between about 70 and 80 years old, maybe older, and she had a notebook which, as it lay open, I saw C++ code hand-written in it in her spidery, old-lady hand. I thought, huh, well it's never too late to start learning this stuff!

There's also the case of the 80-some-year-old Japanese lady who wrote her own iPhone app, a game about arranging traditional Japanese paper dolls: https://social-innovation.hitachi/en/article/colors-wakamiya...

If you're retired, bored, and have a lot of time on your hands, learning tech proficiency and programming seems a good way to pass the time and help keep your mind sharp. Just as it was for us bored kids back in the day.
