Human brains store information in a way that’s not easily measured, nor easily comparable with computers. The unofficial record for remembering the digits of pi is 83,431 decimal places, which would require less than a hundred bytes to represent on a computer.
But anyone can instantly recognise several thousand human faces, from almost any angle and irrespective of expression, hairstyle or lighting. To do this with a computer would require storage of hundreds or thousands of gigabytes.
