57 here, very accurate I'd say! (except for the part about 8 bit computing being boring, I've found people are surprisingly interested in the computer 'stone age' things I've written about lol)

I still write pretty algorithmically complex code for work every day, so no reason to say 30 or 40 is the end of your technical career! It's good encouragement, liked hearing about your experiences. Thanks for sharing this!
