It seems uploading has come a step closer than some week ago. They don't 

bother it seems to put only one neuron on a chip... A rough estimate is that one
neuron ask for 10,000 FLOPs, at 22 TeraFLOPs, they can then simulate 2.2 
billion neurons at real time.

I fear 10,000 FLOPs is aunderestimate by one order of magnitude yet, so the 
system could be good at simulating at full brain only for slow currents. This 
is what I have assumed in other messages : A general purpose computer is good 
for that part of the simulation, it remains to add the fast part, using FPGA 
technology.
