The phone is the sun of the technology solar system

“Today, there are well over 2bn smartphones in use, and there are between 3.5 and 4.5bn people with a mobile phone of some kind, out of only 5bn adults on earth. Over the next few years almost all of the people who don't yet have a phone will get one, and almost all of the phones on earth will become smartphones. A decade ago some of that was subject to debate - today it isn't. What all those people pay for data, and how they charge their phones, may be a challenge, but the smartphone itself is close to a universal product for humanity - the first the tech industry has ever had. When we ask, then, how many people will own a smart watch, or a tablet or smart thermostat and so on, or how connected cars work, or who will control them or what software they will run, it seems to me that the best way to think of this is as a solar system - the smartphone is the Sun and everything else orbits around it."
