i think they say every 20 years or something Technology makes a crazy leap, Like think back to the NES and 20 years after that we were playing on the Xbox and just look at Computers as well Shit advanced like wildfire
i can say probably in the next 30-40 years there will be working Virtual Tech available to the average consumer and be able to buy it from Walmart XD and that Technology in a whole would probably be pretty far ahead that if we
looked back onto today, it would be like when we played NES or when we were using floppy discs XD
