Much, much earlier. Although, it will probably be using real nerve
tissue instead of silicon. Rats have already been cured of paralysis by a
grafting procedure, and the "grafted" cells can be incited to grow by
neural growth factors. Neuro-chip interfaces are in the midst, though...
a non-toxic two-way interface is now possible, and hopefully soon we'll
know how to exploit such an interface, and have the surgical techniques to
connect all the nerves correctly ( or just connect them haphazardly and
let the brain rewire its somatosensory/motor cortices to accommodate...
although this may not be feasible considering how difficult a time the
brain has with rewiring after amputation, ie. "phantom limbs") ... this is
where Anders elaborates on my mickey mouse understanding of
neuroscience...
