Alternative overview: Tour by topic

There is something like a universal all encompassing timeless landscape of technology (an abstract concept).
This landscape turns out to be very well suited to give a general overview over the various aspects of the field of atomically precise manufacturing and technology.

Main article: "possibility space"; (1) R&D with (1a) untargeted research discovering more surprising pathway entry points (1b) targeted engineering marching forward on identified pathway entry points; (2) path, especially incremental path with three technology levels (2a,2b,2c); (3) target backward preparatory design (4) far off target: gem-gum factory; (5a) gemstone based metamaterials, (5b) advanced products and (5c) more abstract consequences (good and bad) hard to quantify and blurring into speculation -- (green areas) Exploratory engineering. (dark green) known today.

The landscape is about the range of fundamentally possible of technologies. The range of these possible technologies is determined by physical law. Under the assumption that physical laws do not change in time or space, the fundamental potential of technology too does not change in time or space. (Assuming unchanging physical law should obviously make sense for all practical purposes. Side notes of little relevance on that here).

Uncovering the fundamental potential of technology is thus not about predicting the future as one might suspect. It's about uncovering truths that where already there since the "dawn of time" (and which hold everywhere).

Specifically in the field of atomically precise manufacturing there is the unusual situation that some things that cannot yet be built or directly tested, can already be understood and simulated. Sometimes more reliably, sometimes less. Some major ones of those areas of investigation in the field of APM that feature this unusual situation are depicted as green "islands" in the landscape above. When isolating a strategy to maximize the reliability of such predictions one ends up with the methodology of exploratory engineering.

Main article: "possibility space"
TODO: reformat to be more vertical and reformulate

• (1) R&D with
  (1a) untargeted research discovering more surprising pathway entry points
  (1b) targeted engineering marching forward on identified pathway entry points;
• (2) path, especially incremental path with three technology levels (2a,2b,2c);
• (3) target backward preparatory design
• (4) far off target: gem-gum factory;
• (5a) gemstone based metamaterials,
  (5b) advanced products and
  (5c) more abstract consequences (good and bad) hard to quantify and blurring into speculation
• (green areas) Exploratory engineering. (dark green) known today.

(1) Developing froward – current R&D

• Experimental work relevant for or targeted at APMnT

(2) Possible pathways

Pathways to advanced APM systems

Incremental path

★ First scaling system complexity from Technology level 0 aka "semi biomimetic self assembly"
★ Then climbing up the material capability "technology levels". Possibly with help of the direct path results.

---

• (2a) Technology level I aka "soft AP block positional assembly"
• (2b) Technology level II aka In-solvent gem-gum technology
• (2c) Technology level III aka Gem-gum technology

---

• Modular molecular composite nanosystems
• Mechanosynelf assembly assemblinting system

Direct path

★ First already staring high up the material capability "technology levels" ladder.
★ Then scaling up system complexity. Possibly with help of the incremental path results.
This may be seen as anearly (possibly limited) window into (2c) Technology level III.

Target structuress in general definition.

• Crystolecules & Design of crystolecules

---

Eaerlier end of target structures:

• Potential early crystolecular building blocks
• Potential early crystolecular mechanisms

---

Mid path wild idea system proposals:

• RepRec pick-and-place robots (GemGum)
• 2D rail-frame based distributed modular pick-place assembly system

(3) Developing backward – preparatory design

• Examples of diamondoid molecular machine elements – Advanced end backwards.

(4) The far term target – kind of targeted manufacturing devices – core exploratory engineering

Gemstone metamaterial on chip factories.
This is the main final culmination and conclusion as the far term target worth aiming for
as a result from the exploratory engineering work done in the book Nanosystems in chaper 14.
Specificlly the table of assembly levels as an example system.
Further chapters on implementation strategies are not part of exploratory engineering.

These ideas are quite faithfully represented in the visual animation movie:
Productive Nanosystems From molecules to superproducts.

(5a) The targeted kind of materials

• Digital control over reversibly composable units of matter

Far term base materials

• Diamondoid, Gemstone-like compound, Base materials with high potential
• NOT: Pure metals and metal alloys

Above the base materials there are Gemstone based metamaterials that allow
to attain lots of emulatable material properties even with just a few high performance base materials.

Low level gemstone structure

• Low level gemstone metamaterial
• Neo-polymorph & Pseudo phase diagram

These are not solid solution thermodynamic nanocrystals of a mixing series with statistic distributions made by thermodynamic means.
These are rather deterministically patterned only kinetically not thermodynamically stable Checkerboard compounds made by force applying mechanosynthesis.

Gemstone based metamaterials

• Gemstone based metamaterial (Mechanical metamaterial, Metamaterial)
• Gem-gum
• Display pixels to gem-gum voxels analogy

---

Some examples:

• Emulated elasticity
• Motor muscles
• Infinitesimalbearings
• Chemomechnaical converter & Entropomechanical converter metamaterials. (Energy conversion)

High level homogeneous structure

Cellular shape shifting tangible systems … as sort of high level (mechanical) metamaterials.

Here often this gives generality at the cost of performance and/or efficiency.

Convenient for black box unspecified magic in fiction writings. Think "Computronium", "Whatevertronium"
Most systems will turn out more varied an specialized across the size scales.
The most prototypical example here is probably utility fog.
