Back in 2007:

“An ambitious project to create an accurate computer model of the brain has reached an impressive milestone. Scientists in Switzerland working with IBM researchers have shown that their computer simulation of the neocortical column, arguably the most complex part of a mammal’s brain, appears to behave like its biological counterpart. By demonstrating that their simulation is realistic, the researchers say, these results suggest that an entire mammal brain could be completely modeled within three years, and a human brain within the next decade… ” Read More Here

then, in 2011:

“IBM has been shipping computers for more than 65 years, and it is finally on the verge of creating a true electronic brain.

Big Blue is announcing today that it, along with four universities and the Defense Advanced Research Projects Agency (DARPA), have created the basic design of an experimental computer chip that emulates the way the brain processes information.

IBM’s so-called cognitive computing chips could one day simulate and emulate the brain’s ability to sense, perceive, interact and recognize — all tasks that humans can currently do much better than computers can.” Read More Here

the next phase of the Project is Construction of the system, and should commence in 2013

Artificial Intelligence should not be too hard once the cognitive process is mapped and applied to the “Computer Brain”
