Who me? Oh yea, thats right. I almost forgot to fold a few trillion of them in the last second - I must have been distracted :-) Last time I went on a nature hike however, I don't recall noticing that level of detail. If you did, I admire your perception, but I'd have to stay away from that trail for my version of R&R.

Not too fast however, to simulate their macroscopic effects for many applications. Unless your studying chemistry. Maybe experimental chemists will be motivated to become Lilliputian Posthumians.
Physical limits to switching speed is a good argument against Von Neumann architecture capabilities, but those limits are not as negative for other architectures.

Very good arguments supporting this are available today. Very good refutations of those arguments remains to be seen.
