Eben Upton spoke at my school during my teens, I remember being so impressed with him that I applied to his college at Cambridge just so that I would be one of his students. Sadly he'd moved on by the time I arrived, but I got the impression that the Pi was largely a result of interviewing so many prospective CS students that didn't already know how to code, whereas in his generation they would have been able to.
I wonder how many CS applicants in 2023 know how to code?
