As interesting information the worlds most powerful super computer was reacently put to work running a simulation of a rats brain, it could only manage to simulate half of it at a 10th of the normal speed, for around 10 seconds becuse of the emmence strain it put on the system.
Point being are computer technolgy is no where near the level needed to create somthing that can rival the surfistcation of the most powerful computers in existence, the human brain.
