I actually gave a talk loosely inspired by that video, about how (as an STM guy) I found Drexler’s designs unrealistic, and that nanotechnology for the foreseeable future would look like those molecular ratchets driven by entropy gradients in warm, wet conditions rather than atomic manufacturing where atoms are chauffeured down an energy gradient in a vacuum to their spot in the final design.
My favorite science communication of nanotech is A Capella Science’s: https://youtu.be/ObvxPSQNMGc
