3D printing on Atomic Level

[mechadense]

To answer the original question - yes I see tremendous potential.

With basic atomically precise productive systems it seems that
all the major problems that currently plague the human society could be solved with reasonable effort in a rather short time.

To make our actions moral we should put effort in:
* waste management
* avoidance of wealth imbalances through rapid change
* resolution of the privacy surveillance dilemma
* measures against chemical weapon production - HalogenCarbides & NOx
* ...

It's not taking over for God.
You need material resources (mining) time (building) energy (plants) and land (to store all that stuff) and most importantly
some smart predecessors that made plans for good atomic arrangements.

btw:
Precious metals cant be made (that would require transmutation)
Body parts will probably produced with "conventional" 3D printing and cell cultures.
