I would agree it's a myth that being 20 years old and ignorant of your own inexperience is a formula for success in Silicon Valley. That being said, this article seems to have a bit of a slant against that demographic. I think it's a wonder so many of the people that age succeed the way they do, given their competition. I'd also point out that Paul Graham has a good point when he talks about some of the advantages being under 25 has if you make a startup - for instance, that you're more likely to learn more tools and not become "set in your ways" so to speak.
