Actually, I think the main point - and the most important take away from the entire article is that working at a startup as an employee - whether its a small struggling one, or a superstart that was born with 100k in seed funding, is a better idea than being a minion at a large corporation - if what you want to do in the longer run is be an entrepreneur.

Also regarding failure - the "its okay if you screw up" attitude is not universal, maybe in Silicon Valley, maybe even in the United States in gneneral - but in most of the rest of the world, people unfortunately tend to not let go of failure very easily!
