I didn't know it was a career option, an academic discipline, anything. Computers were just the thing this boring woman taught us to do spreadsheets on.
At home my old C64 was something that could be programmed, sure, but I was under the impression that was basically a toy. If I hadn't had a parent who were at least interested in this stuff I would have been completely unaware.
In fact worse than that, the boring 'computer proficiency' type courses actually put me off investigating anything to do with this area. Beyond that, with the proliferation of consumption devices, the actual machine and code part of the computer is more hidden than ever before.
Computers run more and more of everything, we owe it to our kids to at least tell them that they can be programmed, and give every kid at least a small intro into how to do it.
