I used to work with a developer, about 2-3 years ago. He was originally CTO of a startup bought by Yahoo! back in the day (Hotjobs). He'd develop live on the server, no version control, yap at you over IM or across the room to get out of the file that he was editing, restart Apache every few seconds to get mod_python to reload. It was absolute chaos. He's a great hacker and a brilliant guy, but some people are truly shooting themselves in the foot for the sake of being "old school". It all comes down to a stubborn laziness. There's definitely a balance between sticking to what you know and prematurely ejaculating over the latest and greatest technologies. Some people just refuse to use new things.

Google "Rasmus Lerdorf". Look at some of his presentations & posts (which btw are impressively ego-free, compared to the usual output of web mini-celebs which achieved a lot less). He's far from being stupid or lazy, but like any good developer knows that thinking of yourself as stupid and acting lazy are virtues that force you to build simple stuff that works.
