If I'm so brutal and don't give a damn why do I care if I use every library under the sun?
Simple you say? Then I'm rewriting code some other poor sods have written 100 times, which sounds a lot like not-invented-here ornamentation to me.
They should rename this screed Arrogant Programming :P
Ridiculous. That list of tremendous people are some founders that found success. There are plenty of tremendous founders we don't hear about that didn't do as well. There are plenty of tremendous people in regular jobs that can't act like iconoclastic dickheads because they'd be rightfully fired. More importantly hugely successful organizations have found a way to reproduce their own success despite specific people not because of them.
You want to build lasting success on good process, good organization and responsible management. People come and go. Organizations stick around.
