It doesn't take special talents to reproduce -- even plants can do it. On the other hand, contributing to a program like Emacs takes real skill. That is really something to be proud of.
I agree. Contributing to Emacs is hard. If it isn't having to wait for copyright assignment papers in the mail, it's a 1000-message-long thread debating the British vs. American spelling in the docstrings. In the end, having sex is a lot easier.
(BTW Is Stallman really THAT... inhuman?)
