My limited understanding of blockchain is that it is decentralized. My experiences with AR have given me the impression that AR is also a decentralized technology, though mobile phone makers can be said to be an international cartel of sorts. As I write this, I am in Chiang Rai, Thailand, close to the borders of Myanmar and Laos, and a few hours bus ride north of the more famous city of Chiang Mai.
I have just spent a few hours with Suphakorn Traisrisin, a 14 year old boy. He is teaching himself how to work with Hewlett-Packard's AR system, Reveal. Suphakorn wants to be a computer engineer, and undoubtedly, when the time comes, he will have a number of geographical options in which to pursue his career. Unlike the businesses of the Industrial Age, the internet has created a decentralized and seemingly level playing field where talent and ideas can take root anywhere and blossom internationally.
I realize this concept/possibility has existed for a while, but it was really brought home watching a 14 year old, very distant from Silicon Valley, teaching himself a cutting edge technology.
