Human brains are currently implemented for a specific embodiment. The
sensory I/O channels for that embodiment would have to be duplicated almost
exactly for the brain being simulated to be able to do/think anything, IMO.
I have not seen anyone address this issue substantively... that is scary.
*I* would like to upload eventually, and thus avoid death, but I want to
upload into a device that provides at least the same quality sensory I/O as
I have in my current body. The recreation of sensory modalities in a
non-biological substrate seems to be a solvable engineering problem, even
with today's level of scientific knowledge. But connecting that new
hardware to the uploaded mind in a way that will make sense to that mind,
would seem like a much more difficult problem. To do *that* right, would
require the human brain be simulated in advance of upload, and that the I/O
channels for all the senses be mapped from the wetware to the hardware. In
order to do this, you are going to have to understand exactly how the
brain's mental processes work. There is no short-cut available here.
Without this detailed mapping, the process of uploading will be horrific
beyond anyone's worst nightmare.
