The section below, adapted from a longer work, discusses the physical basis for understanding atomically precise fabrication systems: first, a very general class of systems, and second, the specific characteristics of high-throughput systems of a kind several technology levels above where we are today. (In my previous post, “A Telescope Aimed at the Future” I said a bit about science, modeling, and as-yet-unimplemented technologies.)
Regarding next-stage objectives for laboratory research and the trajectory of technology development, I’ve previously discussed:
- The path that led from hand tools to automated factories
- Next-stage experimental objectives for nanosystems development
- Self-assembly and directed assembly
- Thermal fluctuations, mechanical stiffness, and error rates
- Next steps in software for macromolecular engineering
Current understanding of potential systems for atomically precise manufacturing (APM) is based on long-established science, not on speculations regarding new or poorly understood physical phenomena. Molecular machinery in biological cells demonstrates the fundamental physical principles and operations that enable APM.
