The sentient machines are descended from an uncrewed factory ship that was to be self replicating, but suffered radiation damage and went off course, eventually landing on Titan around 1,000,000 BC. Manifold: Space, Stephen Baxter's novel, starts with the discovery of alien self-replicating machines active within the Solar system.
Gray goo (also spelled as grey goo) is a hypothetical global catastrophic scenario involving molecular nanotechnology in which out-of-control self-replicating machines consume all biomass (and perhaps also everything else) on Earth while building many more of themselves, [1] [2] a scenario that has been called ecophagy (literally: "consumption of the environment").

Freeman Dyson in 2005. Astrochicken is the name given to a thought experiment expounded by theoretical physicist Freeman Dyson.An Astrochicken is a small, one-kilogram spacecraft, a self-replicating automaton that could explore space more efficiently than a crewed craft could due to its innovative mix of technology.
A self-replicating machine is an artificial self-replicating system that relies on conventional large-scale technology and automation. The concept, first proposed by Von Neumann no later than the 1940s, has attracted a range of different approaches involving various types of technology.

In February 2012, Re-Logic's developers announced that Terraria would be receiving one final bug-fix patch, [6] but development resumed in 2013. [7] At E3 2019, Re-Logic announced the final update to the game. Update 1.4 Journey's End was released on 16 May 2020. Re-Logic stated that they wanted to work on other projects after this update.
Developed by Tomas Rokicki and Andrew Trevorrow. This is the only simulator currently available that can demonstrate von Neumann type self-replication.
