Okay, these guys aren't anywhere near simulating an entire brain molecule by molecule. There's a big difference between this and being able to simulate the storage of a memory.
Also, the estimates of the total complexity of the brain may have all been greatly underestimated. We now have strong evidence from evolutionary Proteomics that each synapse has considerable complexity and is itself involved in computation. This makes perfect sense: the synapse must have evolved from the molecular sensing and navigation mechanisms of single celled Eukaryotes, and these are clearly capable of some computation.
I'm just extrapolating. Given exponential increases in computational power, it's a pretty small jump, I think, to imagine full brain simulation from what they're doing.
