Cyberbrains, Prosthetic bodies. What is more awesome than that. Lot more realistic that say Immortality.

The problem with that is consciousness. Make a copy my brain and upload it to a body, and that's great, but my consciousness is still sitting right here. Transferring my actual consciousness, from my brain to an external vessel, seems like the most impossible kind of sci-fi.

Not that this project is really any bit better. Even if you preserve my brain, there are natural aging processes that will still occur.

Senile robots, everywhere.

thats not exactly accurate. physics dictates in order to make an exact copy of something it has to be destroyed
So you would not remain after the process of transferring yourself.

Since when does physics dictate that? What physical law are you quoting here?

If you want to make a perfectly exact copy of something you need to copy it down to the quantum realm. For example, If there is a photon at point a and you want to make a copy at point b you can't just put a photon at point b. The second photon also needs to have the exact same spin and other features. The only way to do this is through quantum entanglement, which scientists have done over very long distances. To create the copy, you first need to find out the state of the original by measuring it. However, the act of measuring a particle that small actually changes the state of the initial particle.

In short, the original isn't "destroyed", but the state's of all the particles that make up it are altered enough where physicists would consider it to be much different from the copy of the unmeasured original. So you would never end up with 2 exact copies of the same thing.

I haven't done much physics so some of this may not be right.

I am pretty sure that wouldn't apply to this, however I do not think we will be a able to make a copy of someones consciousness until far into the future, if you think about how the brain works, it would not be like copying a hard drive. More like copying RAM or something, and we would also have to learn the brains "language" the thing there is how do even know if 2 different brains speak the same "language". There might be small differences between person to person.
