The comparison is difficult. A computer does one instruction at a time extremely fast and is designed to be 100% accurate. A brain is really slow, but does a bunch of different types of calculations at the same time, but is willing to fill in any blanks with guesses.

A very large computer network can have the memory equivalent of the brain in terms of bits, but the brain learns in a completely different way that a computer is programmed. The brain self-learns by interaction with the environment. This process cannot be duplicated by any number of programmers. The best you could do is give the computer eyes, ears, hands, and legs/wheels, and such, and program it to self-learn like the brain. No one knows how to do that, so the number of programmers required is unclear.
even if you connected all the computers in the world to 1 GIANT super super computer, it will still be unable to overcome a 2 years old child.

the computer does 1 thing a time, if 1 piece of a puzzle was missed the computer will stuck, but the brain (the subliminal brain) can do over 7 BILLION operation a SECOND and he doesn't have to do them in order, he takes all the information and order them as he likes !!
