The idea of atomically precise gemstone based on-chip factories and their technology has faced major disbelieve and push-back in the past.
Here are the probably hardest arguments for this tech to be actually possible summarized in as brief a way as possible.
Contents
Regarding concerns about friction
Concerns about friction have been experimentally dispelled (not only theoretically).
Coaxial nanotubes are already experimentally accessible and they indeed show superlubricity.
- Newer (2017) work on friction (theoretical and experimental).
See: Evaluating the Friction of Rotary Joints in Molecular Machines (paper) - Theoretical estimations on frictions can be found in the book: Nanosystems
More info on and discussion of less common concerns here:
Regarding concerns about atom-by-atom pick-and-place assembly aka piezochemical mechanosynthesis
Experimental demonstration (on silicon)
It was possible to experimentally demonstrate mechanosynthesis of silicon.
Abd that even even with today's still very crude means (meaning blunt tips).
See: Silicon mechanosynthesis demonstration paper or more generally: Experimental demonstrations of single atom manipulation
- Silicon is a relevant material quite similar in covalent character to diamond.
- This has been done an reasonable temperatures (meaning not liquid helium but liquid nitogen)
Highly meticulous theoretical analysis (with carbon, a complete system)
It has been shown that the infamous finger problems like the sticky finger problem and the fat finger problem are invalid.
See: A Minimal Toolset for Positional Diamond Mechanosynthesis (paper)
