The platform may be dead but the concept certainly is not. If anything it will get smaller and less easy to spot. You have a cellphone sticking up out of your pocket and maybe a wristwatch repeater and an earbud, and with the right app you’re good to go. No dorky glasses involved. I’m not saying it’s a good thing, I’m saying it’s an inevitable thing.
Google TV never really caught on. So it went away for awhile and came back renamed Chromecast. But it was simpler, cheaper and worked better.
