To share my own example - beyond SimCity and not-really-understanding-how-to-make-Age-of-Empires-maps when I was 10 years old - I don’t think I can say I was really using computers constructively until I was 12/13 when I was at the point where I actually understood what I was doing with my cracked copies of Macromedia and Adobe software - so if I’m using myself as a benchmark I wouldn’t stress too much about grade-school kids being newbs…
…just please don’t repress them. And introduce them to the concept of creating their own things outside of closed platforms.
Then around 12 I became way more social online, started making custom skins for InvisionFree message boards and spending more and more time in the CSS Zen Garden... and the rest is history!
