What does being 20 have to do with anything? I'm 34 and I've been deeply acquainting myself with Go over the course of the last month.

20 - as in before life starts to throw serious time sinks at you, wives, children, mortgages, high stress jobs etc etc.

At 20, I just did whatever the hell I wanted, bummed around Europe before figuring out where to do my masters. Responsibility was not paramount on my mind. Maybe 20 something's today are different, but not the ones I know, it's still all about having fun, learning new stuff and exploring the possibilities.

I fail to see how anyone could not have understood what the comment meant.

I think he's referring to his 20-year old self, not being 20 in general. I definitely had more time to look at stuff when I was 20.
