Enjoying reading Antonio‘s Chaos Monkeys now. The book is a rather honest account of launching and working at tech startups in the Valley.
Here is a quote on math behind Facebook growth, for example:
“The reality is that Facebook has been so successful, it’s actually running out of humans on the planet. Ponder the numbers: there are about three billion people on the Internet, where the latter is broadly defined as any sort of networked data, texts, browser, social media, whatever. Of these people, six hundred million are Chinese, and therefore effectively unreachable by Facebook. In Russia, thanks to Vkontakte and other copycat social networks, Facebook’s share of the country’s ninety million Internet users is also small, though it may yet win that fight.
That leaves about 2.35 billion people ripe for the Facebook plucking. While Facebook seems ubiquitous to the plugged-in, chattering classes, its usage is not universal among even entrenched Internet users. In the United States, for example, by far the company’s most established and sticky market, only three-quarters of Internet users are actively on FB. That ratio of FB to Internet user is worse in other countries, so even full FB saturation in a given market doesn’t imply total Facebook adoption. Let’s (very) optimistically assume full US-level penetration for any market. Without China and Russia, and taking a 25 percent haircut of people who’ll never join or stay (as is the case in the United States), that leaves around 1.8 billion potential Facebook users globally. That’s it. In the first quarter of 2015, Facebook announced it had 1.44 billion users. Based on its public 2014 numbers, FB is growing at around 13 percent a year, and that pace is slowing. Even assuming it maintains that growth into 2016, that means it’s got one year of user growth left in it, and then that’s it: Facebook has run out of humans on the Internet.
The company can solve this by either making more humans (hard even for Facebook), or connecting what humans there are left on the planet. This is why Internet.org exists, a vaguely public-spirited, and somewhat controversial, campaign by Facebook to wire all of India with free Internet, with regions like Brazil and Africa soon to follow. In early 2014 Facebook acquired a British aerospace firm, Ascenta, which specialized in solar-powered unmanned aerial vehicles. Facebook plans on flying a Wi-Fi-enabled air force of such craft over the developing world, giving them Internet. Just picture ultralight carbon-fiber aircraft buzzing over African savannas constantly, while locals check their Facebook feeds as they watch over their herds.”
