I've seen a lot of this in the programming world. Certain ideas/libraries/techniques will be created and professed so emphatically by their proponent that people accept them as gospel and "the right way." In reality, they're no better (or are sometimes worse) than the alternatives (testing framework, "best practices/agile", and source control standpoints are recent such issues).
I don't necessarily think this is a bad thing, since overly confident people can often be stretched into living up to their claims and genius can often result from that. I'd actually consider David Heinemeier Hansson an example of this. He has admitted his lack of experience when he started programming in Ruby and building Rails (as part of Basecamp) but his emphatic delivery of its benefits back in 2004 led to him picking up followers, gaining marketshare, learning a lot and becoming the genuinely gifted visionary we have today.
