I think this is a somewhat reasonable take. But I am absolutely saying that AFAICT, Drexler’s designs will not work. What you might think are merely problems with building them are, from my view, problems with the entire picture of atom-by-atom 3D printing (especially using reactive species in non-crystalline arrangements) that will persist even if you have nano-infrastructure.
