I really do not know. I will say if it is possible in principle to replace the executive parts of the brain with a computer, but where the result could be a sort of zombie. There are too many unknowns and unknowns with no Bayesian priors, or unknown unknowns. We are in a domain of possibles, plausibles and maybe a Jupiter computer-brain. There is so little to go with this, and to be honest a lot more possible obstructions I might see than realities, that almost nothing can be said with much certainty.
