I have to say that I agree with Gregory here. And it's not just sensors
that are the problem. As I understand it, emotions are mediated by the
'R-complex' and limbic system in the brain. These electro-chemical
processes create the kinds of events we call 'pleasure' and 'pain' in
response to stimuli. They comprise primitive forms of cognition, highly
peculiar, particular, and specialised (i.e. they have to to with the
typical concerns of reptiles and lower mammals), that are 'gerrymandered'
by the neocortex. AI people could perhaps duplicate the functions of
these systems electro-mechanically right now, with enough work, but as
Dennett has said, what's the point?
But unless you uploaded into a system that did duplicate them, you
wouldn't experience them, I think. (Then again, maybe that does provide
a 'point' to the exercise of trying to duplicate them?)
Speculation:- Without systems that duplicate emotional functions, the
nearest I can imagine to what it would be like uploading would be the
experience of doing pure mathematics: all experience would occur as a
kind of mathematical trance, except with sensory images as mathematical
symbols.
This wouldn't be transhuman so much as totally non-human, perhaps no
different from the experience of a built or evolved AI.
