At that time, I would imagine the world as a world with free wifi all over the world. So much so that anything could be downloaded in 1 second and there could be flying cars and vending machines where you could get a hot dog or even a burger instantly. Or AI could be so advanced that people would never have to work, they could just buy a robot that would make everything, do everything and serve you or just work. And comes home from work with money in the evening. That way we just have to live.
