Supercomputer takes 40 seconds to model one second of human brain activity

Given this...

The computer has 705,024 processor cores and 1.4 million GB of RAM, but still took 40 minutes to crunch the data for just one second of brain activity.

...plus Moore's law, how long will it be before the human brain can be modeled by a machine the size of a human brain?

50 years? 100 years?

That sounds like a Google interview question! Well in theory, if it doubles every 18 months, then sometime under 90months/7.5 years they'll be able to do 64 times the computation, or in 1/64th the time.  

Have you ever heard the legend of the chessboard?

I wonder how long until they can model everyone's brain on the planet?  They'll probably just use it for advertising predictive behavior purposes.

Pretty soon we won't even have to click on ads. We'll just have simulated brains to do it for us.

My favorite brain modeling story:

If you perfectly model someone's brain and send it out into space where someone else may or may not find it eventually, does it still exist?
