I am a semi-retired electronic tech/programmer. I get disability and deliver free papers. I am a caregiver for my daughter and an unofficial one for my wife.
I have learned multiple languages. They change, but programming techniques change only superficially, if at all....if you want to make a career of programming is that every 10 years or so, most of what you know will become irrelevant, and you'll need to learn the next thing.
