Self-replicating robot factories

Factories and robots that build more factories and robots with little human labour.

Facts

Lane: Physical world
Wave: 6 of 12 (build order, not a date)
Needs: 11 boxes all the way back through hard links
Unlocks: 0 boxes downstream through hard links
Leverage: None
Cluster: Robots and the physical economy
When: Researcher estimate: 2035 to 2045

Evidence as of October 2026

Forethought argues a set of factories producing parts for each other is collectively self-replicating. The robot stock last doubled in six years; it estimates an initial doubling of about a year, realistically “a few years”.

Watch
Doubling time of the robot stock: six years last time.

Timeline note
My estimate, after embodied agents mature. Forethought expects early doublings to take a few years.
