Real teleportation is impossible and if we talk about mind transfer then it is more reasonable so be in several places at once and just synchronize data betwern different instances so that you can be like god one being in unlimited number of persons (God only has 3 LOL)

other idea is remote controlled body since it is much safer to be in some well protected dungeon and only interface worth though internet. so that you can control selected bodies anywhere on earth. those bodies can be robotic or organic humans or even moderately sized animals.

I think this kind of technology will become real pretty soon because it is actually very simple. It is big puzzle why is is not implemented yet as it is so extremely easy.
Maybe some rich guys are using it already?

This kind of technology will allow to realize pretty much any fantasy because you can become anything you want anytime it can greatly extend lifespan making it close to immortality however it makes you dependent on internet connection.

However regardless on how advanced technology can become we are still restrained by the laws of physic on earth so you cannot improve our abilities significantly you can make yourself a bit stronger but you wont survive if you just from skyscraper even if you are made of titanium and carbon nano fiber and you wont be able to fly or jump on the roof.

Because of this, it will be much more rational to move into virtual world entirely which is free of any restrictions. then forget about the real wolrd entirely, because it is just too boring.
