No, that is not true, because everything depends on the relevant 
FUNCTIONAL level at which the emulation has to take place (a point that 
I made, IIRC, on this list in the last few months).

Are you duplicating the structure of the human brain at the quark level, 
because you reckon the quark level to be the relevant functional level?  
Why not?

You assumed ...... what? ..... that it had to be duplicated with 
accuracy down to the neuron level?  Synapse level?  Molecular level?  On 
what basis would each of these choices be made (i.e., what forces us to 
assume that proper functionality requires that level of detail)?

The point is that there are choices here.  My own work tends to indicate 
that something around the cortical column level of functionality would 
be sufficient for most of the processing.  Now, if that were true then 
an AGI could very well be built using something within an order of 
magnitude of a current PC.

I don't think anyone pays sufficient atention to this little issue.  
Does anyone reading this post truly realize that the implication is that 
if cortical columns are the relevant functional level, and if someone 
figured out what the functionality is, that means someone could build an 
AGI that would fit in (probably) a single server rack, and do so by the 
end of the year...?
