This is already happening, but the tech behind online meetings and collaboration is probably the future of 'tabletop' gaming.
If you want me to get slightly futuristic and not-already-extant, let's go with the tech behind smart-device enabled Augmented Reality ("AR": like Pokemon Go); not to be confused with Alternate Reality Games (ARGs). Give me a library of stock animated critters and a way to hook them to GPS coordinates, so I could GM a group through a virtual wilderness adventure along the bike paths of the nearest green belt park? Yes please: I would love doing something like that with my kids.
