Recent AMD K6-2 delivers up to 1.3 GFlops, and a peak memory bandwidth
of 0.8 GBytes/s. A 30 cm wafer in ~0.1 um technology made of evolvable
hardware is probably the end of the line for conventional
semiconductor photolitho. Similiarly, quantum dot cellular automata,
especially 3d-integrated are the end of the line for integration
density in conventional molecular circuitry.

If quantum computation works in solid state at high qubit numbers and
is sufficiently all-purpose (speeding up ab initio and cracking crypto
seem to be the more straightforward applications) we will have to reevaluate
the computation density anyway.

Whether we ever can harness anything beyond condensed phases for
computation purposes is open-ended.

Well, at least this makes sense; more so than the drivel you send
me personally.

Of course, NASA itself being silent on this issue made it very easy
for all sort of conspiracy theories being developed, and I
certainly felt being hit hard with this export restriction thing.
There's little doubt that quad-21264 motherboards exceed 2,000 MTOPs
and that means that my next PC *will* have export restrictions.
This is even independent of Beowulf stuff - although I have to use
either PVM or MPI on it to benefit from the four processors - as g77
doesn't do automatic parallellisation yet.
