The ones that are good at building something (or at least focused on it) won't be wasting their time trying to "give back" (read: find other opportunities). Zuckerberg did some very minimal "giving back" while building Facebook IIRC (the biggest being an actually useful course he visited at Harvard called CS50, here: https://www.youtube.com/watch?v=xFFs9UgOAlE)
