Luck.
Most people didn't get in the position they were because they were geniuses. Few individuals fill that role. They get there because they were lucky. Bill Gates certainly wasn't the best programmer of his day and he most definitely wasn't the most adept businessman and he wasn't the most brilliant thief.
He was lucky.
He turned out a product that everyone wanted at exactly the right time. Now, as businesses have evolved alongside technology there certainly is slightly less luck (I would personally contend only slightly). But the founders of Netflix probably weren't the first people to think about mailing rental DVDs to customers, they just had the money and the capital to make it happen when the market was just enough ready to accept their existence. They developed expertise in that particular business, mailing DVDs to customers, and killed an entire other industry (for all intents and purposes) in the process.
How the author relates this to their streaming model (what was motivated the change) is baffling to me. Her entire premise seems to try and imply that the wealthy are somehow more intelligent and that, pardon the frankness, is fucking idiotic.
Netflix didn't become a giant through streaming content. They parlayed DVD money into a streaming business because the whole industry was making a very obvious shift in that direction. I mean hell, if they were half the geniuses that the author makes them out to be they wouldn't have selected Silverlight as the backbone of their service.
All I saw was a group of lucky people in one industry try to jump into another industry that appeared deceptively similar, and just because Hastings is their CEO doesn't make me think he's intelligent. If anything he's demonstrated that he doesn't fully understand the economics of splitting media.
The Quickster Announcement came off to me as a very stubborn businessman, tricked into thinking himself intelligent and a captain of industry by his fabulous luck, making a rash decision to vindicate a strong opinion he had behind closed doors.
The only thing I can take from this article is that money does a very good job of making the rich think that they're intelligent.
