This is hardly true of the mind.
Computers have a “memory”; they are storehouses of information; they can make calculations and predictions. They are extremely sophisticated keypunch machines, which by virtue of miniaturisation can perform a myriad of calculations in a minutiae of time within a microscopic amount of space.
High calculations in less time and less space
The computer’s algorithms are programmed by humans and the brain’s algorithms are programmed by evolution.
Considering things in terms of big picture gives you opportunity to make connections
