This is silly, at least to a neuroscientist. Yes, let’s assume that the physicalist or naturalist interpretation of our sense of self and its content are entirely held within our cranium. And furthermore assume that a reboot is possible—as from deep sleep or anesthesia. This leave the open question if what resolution is required to take a snapshot of the embeddings? I don’t think mist neuroscientists would be satisfied with just a perfect synaptic-level connectome. One would almost certainly need to know the the deeper state of each presynaptic and postsynaptic junction. The postsynaptic molecular complex is an assembly of over 500 protein species embedded in and below the plasma membrane. And many of these molecules are labeled by their phosphorylation states in functionally very important ways.
The resolution required to obtain a functional read-out is almost certainly at the atomic level. We are beginning to get close to this level with cryo-electron tomography, but it will take an atomic resolution version of magnetic resonance imaging to achieve the throughput one would need. The dataset would probably be measured in exabytes.
In comparison, a superAGI might be able to run a damn fine simulation of you or me if given 25 years of sensory input and all behavioral output. But to what purpose other than some ill-defined vanity.
Try a mouse or rat first before soliciting VC funds. Has the Human Brain Initiative even managed to nail one 500 mg mouse brain? Not even close!
