I thought the conclusion from that was so obvious that Steve Blank was surely going to talk about it later in the article, but he didn't...
In a startup, the "default" state - if you do nothing - is that you run out of money and starve. That's why fear of failure drives speed and urgency.
In a big company, the "default" state - if you do nothing - is that you collect a paycheck and live a relatively comfortable life. That's why fear of failure inhibits speed and risk-taking.
I recall a comment or an essay of PG's where he said that poverty seems to be a necessary condition for startup success, and without that incentive, startups frequently die. (There are counterexamples like Evan Williams or Travis Kalanick, but in both those cases they picked up their habits while fighting for their previous companies' lives.)
I read that and thought "It isn't so!", and then got a job at Google hoping to do the intrapreneur thing, but with the risk/reward balance slanted toward the big company. I found that there were managers willing to give me nearly carte blanche for finding & fixing new problems, but that didn't mean that I could actually launch or grow anything new or revolutionary. The problem wasn't actually with me or with management or with any corporate structure, it's that for a new idea to take root, you need many peoples' help, and each one of them needs their incentives biased against the status quo. That's why Silicon Valley works: there is a critical mass of people here who get nothing if the startup(s) they back don't take off.
