I consider the full scale simulation of every nerve cell to be a worst case
"proof of principle." It may take a lot less, but if you accept that human
brains have intelligence, then a sufficiently detailed simulation of one
should also exhibit the property.
Last time I did the calculation, considered at the cortical column level
and requiring one square cm of silicon to duplicate the function of a
column, it came out to be about 150 m of silicon on a side and ate the
output of a substantial power plant.
