It is no secret that Apple was not impressed with Google GLASS when it was released. Even when Google was pushing the device harder, Apple was focused more on its smartwatch plans. Glassalmanac has spotted an interesting comment by Tim Cook, suggesting Apple always knew GLASS would fail:
We always thought that glasses were not a smart move, from a point of view that people would not really want to wear them. They were intrusive, instead of pushing technology to the background, as we’ve always believed. We always thought it would flop, and, you know, so far it has.
