Yes, about 200 megabytes! It's a cool paper, but he wasn't actually
trying to measure the capacity of the brain, he was trying to measure
the amount of information that a person knows. He also assumed
optimal compression of the information. It seems unlikely that the
brain stores information in anything like an optimally compressed
As you say, the calculations involve a lot of assumptions---still it's
provocative to think that a person's entire lifetime knowledge base
might fit on a single CD-ROM!
