• I finally got my first computer, Amstrad CPC 464 (8/16bit Z80 4.77Mhz, more RAM than an Arduino Uno but not faster). I was 12 then.
• It was much easier to continue on computers, the learning curve was easier, even if I eventually had to learn assembly on Z80.
• I still knew the basics from school, U = R x I and so forth. I did learn op amps and more in uni, but never really used them and forgot it all
• I spent all my time on computers for the next 20+ years

I eventually gave up on electronics
