Don't overthink it. Just introduce him to something basic. Hell, why not even BASIC hehe ;) I remember when I was 9, my father enrolled me into some "bootcamp", I don't know what it was called back then, but it was some comp programing class for kids, about 3 hours a day for 2 weeks. I remember a teacher, she would just write little BASIC programs on the blackboard and we would just copy them into QBASIC. I remember that I understood very little and the other kids weren't interested much too, we were just eagerly waiting for recess, so we could play Prince of Persia 1 for 15 minutes.At the end of this BASIC "bootcamp", I didn't even touch programing again, I just went home and continued with my mastery of pp and prehistoric 1 & 2 games. But it looks like it planted a seed in my head, because in high school i started wondering what we did 5 years ago in those classes and I somehow found a book on basic and now here I am, writing GOTO statements for profit ;) Just kidding on that last part :) The moral of the story is - Kids can also develop interest much later from the time of exposure to new things.
