Two quotes stand out to me. The opening shot (which you get to read it yourself), and further down this one:
I was asked "Why didn't you patent this yourself, if you developed it first?" My reply was "It only took me an hour to build; if I went down to the patent office after every hour of programming, I wouldn't get very much done."
I can relate to this. At least once, I coded something at some job that 10 years later was covered by some stupid software patent.
