There are examples of Atomically Precise Manufacturing in nature. What will the precursor technologies be when it's finally our turn to play Lego blocks with the universe?!

Resolution:

Techniques may be added as choices if sufficiently general (multiple competing implementations) based on separate physical/chemical mechanisms (no overlap) and have some public recognition. All changes will be discussed ahead of time then logged.

Question will have deadline extended if no qualifying resolution occurs. Question will resolve to "yes" for all techniques used in the process of constructing a

"device able to guide chemical reactions by positioning reactive molecules with atomic precision."
- K. Eric Drexler

The reaction requirement excludes other interesting nanomachines such as motors, heat pumps, or manipulators. The atomically precise requirement excludes common catalyst beds. The artificial requirement rules out minor variations on ligase/polymerase based RNA and DNA synthesis.

There's also the implication of some degree of generality or active vs passive operation - a single-atom iron catalyst or a nanopore pre-filtering reactants does not count!

In general terms, qualifying resolutions should follow the spirit of science fiction and exploratory engineering. The term "molecular assembler" is used for recognition, but alternate terms like "nanofactory" qualify as long as they're clearly on a path towards general Atomically Precise Manufacturing.
