Elizabeth Holmes was a know-nothing with total conviction -- exactly the kind of young person Paul Graham lionizes in his post. She dropped out of Stanford at 19 to found a medical equipment company! When tons of experts believed that the samples Theranos relied upon were too small to yield accurate results! Which turned out to be true!! There are, of course, a handful of businesses that have done quite well and defied all expectations in the process. But they are the exception rather than the rule. Most startups fail, and it's not at all obvious that being completely sure of yourself despite (because of?) your ignorance is an advantage.
