Tim Cook has talked up a lot of tech­no­lo­gies since becom­ing Apple Inc.‘s chief exec­ut­ive in 2011. Driver­less cars. Arti­fi­cial intel­li­gence. Stream­ing tele­vi­sion. But no tech­no­logy has fired up Cook quite like aug­men­ted real­ity, which over­lays images, video and games on the real world. Cook has likened AR’s game-chan­ging poten­tial to that of the smart­phone. At some point, he said last year, we will all “have AR exper­i­ences every day, almost like eat­ing three meals a day. It will become that much a part of you.”
