Idk what Dijkstra means. My whole generation started with BASIC and learned languages as they’ve become useful enough for every new wave of accessible hardware, which wasn’t cheap for a hobby. There was no like “oh, now you’re lost”. My next language was 8080 assembly then Pascal then 8086 then C. You just can’t learn Pascal and C on a Sinclair clone when loading a compiler from a tape recorder takes half an hour and most of the available memory. And you can’t learn Python either, because it doesn’t really exist yet. I know it’s from 1991, but never heard of it until ten+ years later.
I also know that some ROMs had FORTRAN instead. Maybe Dijkstra would like to re-teach FORTRAN programmers more.
