Good luck! Just remember you'll also need a job that pays the bills. :-)

Sounds like you have a horror story in mind. ;-)

Theorectically it shouldn't matter.

"Bacteria" and "bacterium" appear to be synonyms.

An assembly line implies directed motion. Biology at the cellular level=20
generally relies on heuristic motions. Their operation is not=20
deterministic, while macro-sized machines are. It is the deterministic=20
nature of Drexler's molecular nanotechnology that yields all the
wonderful=20
possibilities.
So while a line of bacteria, each one doing a different job, might be
made=20
into an assembly line, the design effort would be better spent on=20
deterministic operations from the very start.
