Well, CyTG compared the 1 million with (a very conservative estimate of)
1E14 for the brain, which suggests he was referring to updates of individual
synapses. If he meant 1 million neurons of 1000 synapses each, then that
would make sense, but the comparison is then not valid, and the computer
comes out looking better than had been suggested.
