For the record book, did Eric first present this pardigm at Extro3
or at the 1998 Foresight Institute Senior Associates gathering?
I seem to remember it being part of the discussion regarding the first
presentation of the Crit software, but my memory is fuzzy and I'm
unsure of when this occured.

I will freely admit to "borrowing" Eric's comments in my discussions of this material.

No, absolutely not. You "probably" do not need to be frozen (or dead) to be copied/uploaded. However, the degree to which your brain is "active" during the upload, will certainly "blur" the quality of the copy.

You simply must read Nanomedicine for us to have a good discussion about this. It is fairly clear that (a) nanobots can map the location and strength of the synapses, (b) can do real time monitoring of the neuronal firing noninvasively (by monitoring power dissipation at the 1 mK level), and (c) can outmessage this information in real time (though it may require a not-invisible fiber optic bundle). What isn't clear to me at this time is whether or not additional cooling capacity would be needed in the brain to handle the power requirements for this monitoring/outmessaging, or whether the network installation could potentially disrupt normal brain functioning (though I would believe we could recover from this if it is done gradually).
