That synaptic connection bit also means that a) his simulated brain is static and can't learn more than what sustained activity can hold in memory and b) it has some highly redundant structure allowing him to compute the weights. Both are not true for natural brains, making his estimate somewhat optimistic, I think. Hm.

I wonder how much additional overhead this technique caused, and how much longer the simulation ran as a result. Also, is anyone else satisfied with waiting 40 years to run these quickly? This makes it especially clear that we'll need alternative hardware. Good luck to Blue Brain nonetheless...
