If human algorithms for sensory processing are copied in full, the new beings will also have most of their thoughts about experience caused by experience
That reads like a non sequitur to me. We don't know what the relationship between algorithms and experience is.
Mentioning something is not a prerequisite for having it.
It's possible for a description that doesn't explicitly mention X to nonethless add up to X, but only possible..you seem to be treating it as a necessity.
I'm convinced by Kurzweil-style (I think he originated them, not sure) neural replacement arguments that experience depends only on algorithms, not (e.g.) the particular type of matter in the brain. Maybe I shouldn't be. But this sub-thread started when oge asked me to explain what the implications of my view are. If you want to broaden the subject and criticize (say) Chalmers's Absent Qualia argument, I'm eager to hear it.
I found this article on the Brain Preservation Foundation's blog that covers a lot of common theories of consciousness and shows how they kinna miss the point when it comes to determining if certain folks should or should not upload our brains if given the opportunity.
