I think one of the most interesting technologies that should be brought to real-life is something similar to the Link Units from Avatar and Surrogates. These machines allow a user to essentially transfer their conscious to another entity (whether it be machine or biological) so that they can explore the world in a different body. In Surrogates, the surrogates have increased strength and speed allowing them to achieve super human feats. This power is inevitably abused in the world of the movie where people only ever interact with the outside world with their surrogates, but Avatar shows how we can also use these surrogates to explore worlds that are too treacherous for humans.
In Michio Kaku’s book “Physics of the Future”, he touches on this technology by mentioning how, instead of flying to different planets that are deadly to humans, it could be faster and easier to explore different worlds by simply transferring our consciousness to a robot already on the planet. These robots would be stronger, faster versions of ourselves making exploration safe with no real threat to the user. Plus, it makes vacation much cheaper when you don’t have to pay for those expensive spaceship tickets.
It also brings up the interesting point of how people would react when their consciousness is transferred to a robot that, perhaps, has four arms instead of two, or has 8 eyes! How would our minds adjust when having to cope with extra parts on our robot bodies.
