But the numbers don’t lie, and if Apple knows how to do anything it’s sell iPhones. That’s an impressive number on its own, but it’s even wilder when you consider that Apple is picking up the pace. The iPhone was introduced in 2007 and the company reached 1 billion iPhones sold nine years later in 2016. Getting to 2 billion took only five years; from there it’s been just four years to sell another billion. At least from the outside, Apple doesn’t seem terribly well prepared for that world we might be living in ten years from now.
