The upload cannot be traced back to the original if a way is not shown for the activities of the copy's central nervous system to be a causal contact with the original. I don't object to this in principle, but IMO the Moravec transfer is insufficient to effect this. In simulating the synapse activities of a single neuron, one would have to have an accurate simulation of the rest of the brain to properly model or engineer the biological neurons and synapses which would affect the synapses of the robo-neuron. This is circular reasoning. The way a Moravec Tranfer describes robo-neurons to be built first, and then synapses replicated, cannot function in practise without compromising one's identity. The smallest pattern losses, or more accurately differences in chemical or quantum states, will propogate throughout the system very quickly and eliminate identity. Moravec transfers and flash-uploading are the same process, they must live or die by the sword, together.

You can trace the upload of Phillip Huggan back to the biological
Phillip Huggan in exactly the same way you can trace the Phillip Huggan
that exists now to the one that was around 5 seconds ago.
