Adding an implied ad hominem remark doesn't alter the fact you immediately contradicted your own advice.
If you meant "structured education of some form" and instead specified "school" I don't really see it's obvious the generality was intended.
Indeed the likelihood arises now -- given your implicit suggestion that people who don't attend formal schooling are somehow deficient -- that in fact you only considered school when you made your initial remark.
You teach your kids how to read, how to do math, history of the world - Computer science will soon be no different. Might as well get ahead and teach them during learning time.
What makes you think that? It's a very specialized field. It's not going to be something parents are casually teaching to their kids.
When I was young (12-15) I spent a lot of time programming and very little interacting with other people outside of school hours.
The same thing can happen with video games or even reading of course.
