Today's VR (AR) tech ala Halolens, Pokémon Go, Google Glass, etc is something I personally do not like, however I would love to live to see the day that I can walk into my living room, flip on a game of Gears of War and the emergence hole appears on my living room floor.  I am fascinated by the holographic technology but I am just not on board with it yet.  However, I would love to use it if I could walk into the room and say, "Computer, load up Gears of War 1 and I will play the character of Dominic Santiago" and the room transforms into that war-ridden planet of Sera.  Will that happen in my lifetime?  I just turned 50 so I am not foreseeing it.  Perhaps in my grandchildren's future.
