I am writing a short story and would like to know what would be the most realistic way to introduce a human to robot interface (exchanging data with an AI robot)? I was thinking of some kind of a chip that would be put on a human head (or implanted if needed) that would be able to "read" what's going on in the brain and transmit that data wirelesly to a robot.
My question is does something remotely similar exist today and would something like that be possible with future technology (like 50 to 100 years in the future)? I'm also interested in being able to "copy" a person into a robot, so bonus points would be for that chip being able to not just scan current brain waves but also to be able to "copy" your brain (memories, knowledge etc...) to a robot.
I might have not been precise enough, so to clarify, I was looking for a robot to human interface that would allow for them to exchange information. Not just speech or thought per se, and not in a way where robot knows what we are thinking of as a textual info. As I said in a comment to one answer, data that I am aiming to exchange through that interface can be images or memories of some event both visual and aural. So not just describing something to a robot textually (or robot to us, data exchange should go both ways), but actually sharing information as we have seen it or as we envision it (or robot).
And that's where the bonus part comes, being able to "copy" a brain to a robot. So the first part of the question is whether it would be possible to make that kind of an interface for exchanging data with AI in the future, and the second part is would it be possible to scan a human and store him in a robot (immortalise a human in a way). I know that we know nothing about consciousness yet and would that robot then be conscious that it's the same person it was before the transfer, but question is primarily would it be possible to copy all of the knowledge, memory etc... from a person to a computer. Now that I think of it maybe I should have split this into 2 questions.
