Even the most trivial computer programs have lots of bugs (with VERY few exceptions [1]), and we're worrying about creating a super-brain that is actually smarter than we are ourselves ?

And let's not forget the debugging, which is TWICE as hard as the coding ;-)

We may be able to simulate the hardware of the brain (using "biologic hardware"), but programming the AI software is probably greatly under-estimated....

[1] Some of the NASA software is probably as close to bug-free as we get, and check the required amount of planning, documentation and testing compared to the amount of actual code produced - http://www.fastcompany.com/magazine/06/writestuff.html

The human brain has much more bugs than any current piece of software.

The actual program will be small. The brain is clearly a learning agent in a task environment. The sensors and actuators are implementable, the only real question is what algorithm should process the input stimuli.
