I think he meant he was working/studying CompSci and his grand-parents didn't understand what he was doing.

That's not quite what he said. He wrote: "I heard for the best part of my adolescence and childhood that 'sitting in-front of a computer will not put food on your plate'."

I interpret that to mean he was talking about his childhood.

[PartiallyTyped]

He is partially correct, my childhood and early adolescence was spent on video games, my later adolescence was spent on CompSci and reading. I explain more in the sibling comment.
