Open source and extendable software makes this argument redundant, surely? We write good code (as opposed to quick code) in order to make it re-readable and updatable later; making the logic machines more dynamic and, ultimately, functional to end users? Equally rock star, ultra-pretty code like rails (or even ruby itself) which writes 9/10 of the program for you is also a massive win for customers who get the benefit of cheaper logic machines (because people only have to write the unique/problem-domain components.) also, I agree with DanielBMarkham, putting a TLDR at the top means I don't read the whole post (which was definitely TL...)
