In zuckerberg's speech he shows one of many innovations that will drive all current sunglass wearers to switch to smart sunglasses which is the glasses keeping score of your tennis, ping pong ..card game ..whatever game and displaying the score in your view.
Though His example really just shows the glasses telling the player the tennis or pickle ball was out of bounds. I've just expanded it to keeping score of whatever game and or counting things in front of you to counting how many in a room to etc etc etc ones imagination can think of. The glasses will make life easier and in a magical way that drives all sunglass wearers (about 75 to 90 percent of the entire global population) to switch to smart glasses.
