I know everyone likes to tout VR, but I really think that AR will be the sweet spot most people ultimately adopt. Add it into nice looking glasses (sorry Google Glass, not it) and have some sort of easier to use interface that can interact with your surroundings and that will take off.
Imagine being in a business meeting with a little pop up over each person’s head with their name, title and other interesting information you need to know. Or be at a baseball game and have similar stats pop up above each player’s head. Turn by turn directions overlaid directly on the street. There are endless possibilities (as long as the ads don’t get in the way, but even for them, imagine green screen billboards that can display unique ads too).
Nah, if that’s the goal they’ll just use Neutrino Bombs (look them up, they’re crazy what they’re designed to do)
