Yeah. It would require such incredibly advanced autonomous automation that... well, it'd solve most contemporary manufacturing problems here on the ground, anyway.

IMO anyone pouring money in this stuff should read Project Rho, and maybe OA:

It's fantastic speculative engineering. It's also a cold ass bucket of water.
