I took this more as Steve writing a reminder to himself of the debt he owes to society. Almost the entire basis of his success isn't because of his own work or innovation. It is 99.9999% the work of the people around him, and the work of tens of thousands of years of humans throughout history. I imagine sometimes this is hard to keep in perspective if you're rich, famous, going down in history as an innovator, and have quite the ego.
