I'm from a complicated class background myself, but my dad's family were tinkerers. My grandfather was a factory worker who was obsessed with televisions, so when my dad got into microcomputers, the tools were around for him to start cheaply because he could use/repair broken ones. And then when I was born, my father's experience meant he could help me with coding. (Because in his generation, you had to learn BASIC etc. to do anything).
I'm not any better than say, the kids of my dad's classmates. We were just the family who did the grunt work in an area that really took off. Their grandfathers might have liked sports instead of tearing open tvs.
