The density is relatively irrelevant (how much cool stuff could
you do with a rodent equivalent?), it's the latency (several ms vs
several ns of RAM, a factor of one million) and the bandwidth (some 0.1 
GByte/s vs. 6 GByte/s, a factor of one thousand).

It would be nice to have a TByte of RAM, but it would be far
nicer still to have a 10^12 cell assembly, each capable of
a 10^10/s refresh (the individual switches now could do half
a THz).

But no can do with rotating bits, magnet domains.
