Good point - what might become fun and engaging at 10 or 11 could be more frustrating at 8, especially on your own.

As near as I can remember, my first real programming experience was when I was eight years old, writing basic programs on an Apple IIc at school in 3rd grade. (I was too poor to afford my own computer until my senior year of college). It was awesome.

I have never found computers disappointing, and I have spent most of my career/life learning about them - from processor design through to distributed systems. Mostly I've been disappointed in the disparity between the number of interesting things I'd like to do, and the number of lifetimes I have available to me.

Different strokes for different folks, I guess.
