Any tech that is invented, and implanted on human beings, without studying the humans themselves. is bound to fail. Humans are smart mammals and they do appreciate anything that's smart, however they didn't come from a fancy space ship as google has established. they were born on the earth. that is full of colors, breeze, green fields.

on a serious note, what happened to Google Glass??

regardless of downvotes, I am convinced that all these 'efforts' are solely aimed to stay relevant, Tech is changing at a pace that no one could have predicted. Even Apple is paranoid. Who had thought iphone 6+++?? I don't mean it's uncool. But just see how things are happening fast and quick. It's hard to catch up.

Google has more failures in recent years than any other company, because either they were too late to the party or too early. i.e Google Plus / Google Glass etc etc.

iPhone was not 'too early' it was just in time. that's why it was a major hit. Give me something that I would start using today(). If it's practical and useful it is gonna be hit. Else beyond the headlines it would only be biting the dust in the labs.... a privilege that until now, solely belonged to Microsoft
