I'm pushing 50 and when people ask me how I know so much about computers, my first comment is that I had to program my first computer for it to do anything.

My second is that I actively sought to learn, and you can too.

Later in life Linux played a huge role in understanding how these contraptions work. Ironically, I'm a human factors engineer, so I'm also guilty of creating part of the problem. User interfaces that "just work"... Until they don't.
