The disk is designed to be copyable. The brain is not. See e.g. this evolved circuit:

https://www.damninteresting.com/on-the-origin-of-circuits/

The brain is, as far as we can tell, more like that circuit than a disk. Information is encoded within the structure of the processor itself, rather than being one of 2^N easily defined conformations of a memory device. As such, there is no way to copy the memories of brain A into brain B -- it simply isn't a thing. It would be like saying: copy all of the stains on this shirt, but the stains are integrated into the fibers and are unique to the stitching. In particular, this statement is false:

>Your real, natural brain can access the information within itself.

It cannot, for example, I cannot fully describe how to walk, given a pair of human legs and a butt. My brain can only encode information into language in the particular ways in which it is "designed" to do so. There is no way at all for the brain to report, e.g., the number of synapses within it, even if the firings of some neurons are recorded electronically.

I say "design" in this sense because the structure of my brain is contingent on its fitness-for-purpose in a way that affected its formation, via biological evolution, similar to the way that the structure of an intentionally designed object is contingent on its fitness-for-purpose, which affected its formation as it was constructed by the entity which made it.




Well then. If copying's out of the question (for now), then I propose Plan B:

A single brain, in a secure location, remotely controlling multiple bodies (one at a time, but able to switch between them.)

• Identify all the points of contact – the I/O pins – between the brain and body.

• Identify the medium and format of communication between brain/body/senses. I think most of this has already been achieved.

• Grow a body, a shell, without a brain.

• Take your brain out and keep it alive in a vat.

• Put wireless transceivers at each I/O point on the controlling brain and the shell body/bodies.

Will anything like this be remotely (<pun) possible?

You'd have to get used to lag but in the case of a fatal accident/violence* and most diseases your brain would be safe and able to switch to a new body..

I expect something like that would be very valuable to soldiers and workers in hazardous environments, like space.
