The software design appears a lot cleaner than the hardware, with friendly icons and unobtrusive notifications. But Google's concept video portrays perhaps the loneliest vision of the future ever.

A man starts his morning by putting his glasses on, then goes through most of his day talking to himself, without actually interacting with anyone face-to-face, save one friendly pat of a bulldog and a super-quick visit to a coffee truck with a buddy.

A notification delivered in the morning to "See Jess tonight at 6:30 p.m." turns out not to be an actual date, but a video chat. As the sun sets, Google's protagonist remotely serenades his friend's avatar with a ukulele.

What Google's final version will look like -- and whether it will actually end up on store shelves -- is anyone's guess.

But Google X's futuristic sketch proves that those little plastic rectangles we've been accustomed to communicating though could soon be outdated technology.
