I think the dissipation problem can be dealt with using reversible
logic, there is already a fairly large literature on the subject.

As for size, it seems like we need a jump to nuclear densities
("femtotech") to go beyond nanotechnology. That might be a real limit
since nuclear matter is so unstable at our energy/density scale:
We don't have anything like Drexler's proofs of concept for femtotech.
