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.
Yeah, I realized I started to sound snarky when I said "I work on computers" when people ask me what I do. Didn't mean it to sound dumb, it was just honestly the level of understanding about computers a lot strangers had when they asked.
Saying I did networking or worked with servers didn't mean much, but sometimes people would ask me to work on their WiFi...
