Yeah, that is surely a step forward.
But simulating a worm is way too far from simulating a human brain. And also I'm not sure if this is a right path (Just IMHO).
Luckily, I've been working on the framework of simulating the human brain and I've got a theory. In the next few weeks I'll be working on realizing this framework and release a demo. If this works, I will post it on HN. :)
