Apple is credited with inventing the smart phone when they actually didn't. But they made the first one that actually caught on. Intellivision (competitor to Atari) actually invented online gaming from your home in the 80's, but of course they were ahead of their time and failed. Thomas Edison is thought by most to have invented the light bulb. When in fact it had been around for a while, he just made improvements that made it much more useful and long-lasting which catapulted it into usefulness for the average person. So, sherbros, what tech currently exists but hasn't "taken off" yet? My nominees: 1. Google glass - This was considered a failure but mostly because the world wasn't ready for it. People hated the idea that they were being recorded all the time so they rejected these. This to me is a social thing and as people get more comfortable with the idea of always being on camera I think google glass will be a part of our future. Google may not even be the one to do it either. A company like Apple might come out with their own version and since their followers are zombies they'll all run out and buy it. 2. 3D printing - People may argue that this has "taken off" already but I disagree. It certainly has not lived up to the hype that promised it would change the world, and that everyone would be using them. It's cool that they exist but improvements have been slow and under the radar. It's a niche product for specific industries and hobbyists only at the moment. But I think someday someone's going to find a reason for everyone to have a cheap one in their house. Even if it's for little girls to make bead necklaces or something stupid like that.
