Maybe not playing games, but we will still be arguing about FFVII when we are 86 years old.
Legions of old mostly-men, peering at 2D screens, smacking at keyboards, while all the young'uns are off running around with their neuro-taps and neo-English and making fun of the old fogies and their endless debates about Aeris and Sephiroth and bringing in their quaint wall scrolls for show and tell.
Sounds like an idea for a screenplay for a futuristic sci-fi movie, maybe a comedy. We would have Shigeru M. cryogenically frozen, like Walt Disney, at the Video Game Hall of Fame. We'll be ranting on about "that's the problem with kids these days, they don't appreciate the simple gameplay over the 5D graphics in the games that they are playing now". We'll have the Siskel and Ebert of video game criticism and every video game release will be accompanied with a party that has a red carpet. By this time, Final Fantasy 77 will be out, along with Super Mario Universe, and there will be motion controls.... in space. Discussion shows will ask "is Zelda a RPG?" and games like Final Fantasy VII will be celebrated as classics, like Intolerance by D.W. Griffith and the Ten Commandments by Cecil DeMille. We'll actually have virtual reality nursing homes with robots that bring us food and dessert.
Every other fabric of my being will be an even greater enigma as by that time, all of The Beatles, The Rolling Stones, and other bands, artists, moviemakers will be long gone by then. It will be a lonely, frozen world but I will manage. There are even a few reports that our generation will live long enough to see Final Fantasy 88.
