My brain has redundant pathways to memories and almost certainly stores memories in multiple locations. However, the primary comparison was not to brains but to encyclopedias or books (in keeping with ancestor comments) specifically and other technological artifacts in general.

And therefore, books are more akin to the permanent storage devices such as disks you mention (though tending to be far more persistent).

Generally speaking, It is my belief that computers are not significantly more isomorphic with brains than windmills and any conclusion that there are homuncului should be taken as a reductio ad absurdum against an isomorphism between brains and the internet.
