TLDR:autofac requires solving “make (almost) arbitrary metal parts” problem but that won’t close the loop. Hard problem is building automated/robust re-implementation of some of the economy requiring engineering effort not trial and error. Bottleneck is that including for autofac. Need STEM AI (Engineering AI mostly). Once that happens, economy gets taken over and grows rapidly as things start to actually work.
better CAD/CAM (this is still mostly unsolved (CF:white collar CAD/CAM workers))
AI for tricky robotics stuff
estimate:100-1000 engineer years of labor from 99th percentile engineers.
Median engineers are counterproductive as demonstrated by current automation efforts not working.
EG:we had two robots develop “nerve damage” type repetitive strain injury because badly routed wires flexed too much. If designers aren’t careful/mindful of all design details things won’t be reliable.
This extends to sub-components.
Closing the loop needs much more than just “make (almost) arbitrary metal parts”. “build a steel mill and wire drawing equipment”, is just the start. There are too many vitamins needed representing unimplemented processes
raw materials production (rock --> metal) and associated equipment
wire
Those in turn imply other things like:
refractory materials for furnaces
corrosion resistant coatings (nickel?, chromium?)
non-traditional machining (try making a wire drawing die with a milling machine/lathe)
ECM/EDM is unavoidable for many things
Things just snowball from there.
Efficiency improvements like carbide+coatings for cutting tools are also economically justified.
All of this is possible to design/build into an even bigger self-reproducing automated system but requires more engineer-hours put into a truly enormous git repo.
STEM AI development (“E” emphasis) is the enabler.
Addendum: simplifying the machine tools and robots
Simplifications can be made to cut down on vitamin cost of machine tools. Hydraulics really helps IMO:
servohydraulics for most motion (EG:linear machine tool axes, robots) to cut down on motor sizes and simplify manufacturing
efficiency is worse, but saves enormously on power electronics and manufacturing complexity.
Similar principles to hydraulic power steering used in cars.
Boston Dynamics ATLAS Robot uses rotary equivalent for joints (I think).
hydrostatic bearings for rotary/linear motion in machine tools.
No hardened metal parts like in ball/roller bearings
Feeding fluid without flexible hoses across linear axes via structure similar to a double ended hydraulic cylinder. Just need two sliding rod seals and a hollow rod. Hole in the middle of the center rod lets fluid into the space between the rod seals.
Both bearings and motion can run off a single shared high pressure oil supply. Treat it like electricity/compressed-air and use one big pump for lots of machines/robots.
End result: machine tools with big spindle motors and small control motors for all axes. Robots use rotary equivalent. Massive reduction in per-axis power electronics, no ballscrews, no robot joint gears.
For Linear/rotary position encoders, calibrated capacitive encoders (same as used in digital calipers) are simple and needs just PCB manufacturing. Optical barcode based systems are also attractive but require an optical mouse worth of electronics/optics per axis, and maybe glass optics too.

To expand on that:
“make (almost) arbitrary metal parts”
can generate a lot of economic value
requires essentially giant github repo of:
hardware designs:machine tools, robots, electronics
software:for machines/electronics, non-ai automation
better CAD/CAM (this is still mostly unsolved (CF:white collar CAD/CAM workers))

A minimalist industrial core needs things like:
PCB/electronics manufacturing (including components)
IC manufacturing is its own mess
a lot of chemistry for plastics/lubricants
raw materials production (rock --> metal) and associated equipment
wire
