I thought about the possibility of having several live streaming web cams focused on the same area, feeding all this information at once into a HD, and having it resurrected as a 3D (4D?) world wherein users could enter and float around like flies, talk to one another, and even manipulate remote controlled robotic machinery using various commands that are sent online and received by the robots. Applications might include medical operations where specialists from all over the world can work together in one room, and working on space stations and satellites. The technology is already with us, I believe, to make this happen. Feasibly it could be used to enable people to buzz around in real time anywhere the 3D video technology is set up. Societies could evolve where people transcend their human forms and even become immortal.
