Just as in computing there is a tradeoff between what's in RAM and
what's on the
disk, I expect extended external storage with a good interface might
this concern. I don't expect this can be done with brains as is, and
that some
serious structural modifications are needed. Alternately, the processes
for cryonic restoration might allow periodic "sweeping" through the
relegating less important memories to the external storage, creating
for new memories. In AI, this is known as "garbage collection".
