Teach computers?
That is very much a case of those who can't teach. If you have any talent with computers you can make a whole lot more than in a teaching job. I've never come across a teacher with any skill at computing, including the huge majority of lecturers at university.
I'm 30, and I've been programming computers since I was 8. Schools don't do programming, they do boring stuff like word processing and spreadsheets (and probably emails and web searches now). Fine if you just want to be another office drone, but the real fun is making the computer do exactly what you want, and to do that programming's where it's at.
As far as I'm concerned all children should be introduced to programming as soon as they can read, as it builds logic and problem solving skills like nothing else at school, and gives you somewhere you can make use of mathematics topics, besides just answering questions from a book.
It's a lot better than just writing or typing out something, that afterwards can do little more than be read. You write a program and it can make noises and pictures, or ask people questions, and you can go in and make changes to what you've already done, so it does something else, exactly the way you want. If like me you're not very coordinated and have trouble drawing, or playing a musical instrument, it's nice having a creative outlet where all you need is the manual and a bit of patience. The best part about programming is that the mistakes you make help you learn new things.
