Well, I’ll provide a slight counterpoint. I started programming on BBC Micros as a 9 year old. The BBCs were old then, but Apple had yet to bring out their subsidised Mac Classic program, and primary schools in Australia didn’t have huge IT budgets. We persisted with them until 1991. That was a great foundation, even if I tend to agree with Dijkstra on BASIC programming these days.
However, on the slide rule front, despite being under 40 years of age, I can and do use them still. My father made me learn how to use one when he got disgusted at some young whippersnapper using a calculator to resolve a bunch of equations during planning for the RN’s last batch of Jindiviks to be built. Dad consistently managed to obtain the answer more quickly, at which point he decided his son needed such skills.
When I inherited my grandfather’s slide rules (he worked on telemetry for the UK/Aus space program), I decided to demonstrate their function to my kids. They think slide rules are magic. Calculators, not so much. I occasionally still get asked to demonstrate my magical multiplication method to the under-10s.
(Frank Cleggett, ELDO liaison officer, at Mt Eba tracking station, c.1970. No slide rule evident, but some awesome old skool tech is)
