Speaking of nano-technology, I've got a relevant question.
AFAIK, nanobots will use molecular conformation changes (e.g., Drexler's
"mechanical" computation) or electronic energy-level transitions to
process internal information.
Drexler info:

Which has more advantages, mechanical computation or computation using
electronic energy-level transitions?
