Don't forget that you will not need all of those neurons! There are redundant neurons, audio/visual/sensory etc that might not be applicable to your cause. Also, a hybrid method that can store data permanently (instead of forgetting it) would work better without neurons, Therefore you could save simulating a few billion neurons.
Well, maybe it was deliberate? We're all talking about it :-)
