I'm writing an article for H+ magazine about this subject. My prediction is that the upload will experience something, but in a fundamentally different kind of way. So I think the color experience, for instance, won't quite be the same. My idea is that many physical changes, can radically change this experience with respect to the upload's human form. Basically, I continue my AIT based theory of qualia, and I reach the conclusion that, some information, and thus some qualia, will be shared by the human brain and its upload simulation, but the simulation will naturally have the algorithmic information from: the simulation program itself, the physical make-up of the processing elements, wires and communication, i.e. the hardware that the program runs on. If for instance our brains' chemical reactions are part of that, then, by not simulating those chemical reactions, we might be losing some resolution and the fundamental quality of the media. We might find that the digital experience is much more digital sounding and harsh, so maybe even the difference of analog vs. digital computation is felt, and then there are material-bound changes. I think that an optical computer and a digital computer will give rise to different kinds of experience. Maybe we'll prefer the light form better :)
