No, there really hasn't. And it's a little embarrassing. Lawyers, doctors, carpenters, electricians, engineers, etc. don't feel the need to produce countless rhetorical manifestos. I'm not sure why our profession (or craft, or whatever you want to call it) has to come with so much cultural baggage, especially when there are so many real problems left to be solved.

I think it's only natural because software development is an intrinsically creative endeavour.

Unless he had to solve boring problems.
