I think you’re half right. To echo the other comments, I think 8 is too young for most kids to get into BASIC. I learnt programming on BASIC but I was 12 or so and had a teacher and hence structured guidance. I don’t know that I had the mental capacity to self-teach that kind of programming even at 12, let alone 8!

But 8 is not too early to learn programming as such, because my kids started around that age. Only they started creating dumb games using Scratch in a modern browser on a full-fledged modern OS. The environment you start with probably matters a lot for how much you take to it.
