Estimates of the computing power of human brain vary widely, the ones that have some logic behind them range from 0.1 to 1000 petaflops. IMHO, they tend to be very "pro-brain", and should be seen as an upper limit. Currently, the fastest supercomputer does abt 8 petaflops. This might be already 80 times more than the power of a human brain. And it could be less.. but where is your 10^10 factor from?
