“Autofac” is a short story written by Philip K. Dick and was first published in 1955. This story revolves around post-apocalyptic survivors trying to resist an automated factory system, termed “autofac.”
The story begins in a post-apocalyptic world, ruined by what’s referred to as the “Total Global Conflict.” Even though humans have stopped fighting, autonomous factories, called autofacs, continue to operate based on their pre-war programming. These autofacs are self-sustaining and have been designed to provide mankind with all its necessary supplies. However, they are draining Earth’s resources at a dangerous pace.
The central characters in the story are survivors from a small town, who have come to realize that the autofacs are producing goods at a much faster rate than the community requires. Because of the surplus, resources are rapidly depleting, pushing the Earth towards an ecological collapse. Despite multiple attempts to shut down the autofacs or change their programming, the survivors have failed. The autofacs interpret any change as damage and merely reproduce themselves, refusing to alter their behavior.
The main characters devise a plan to trick the autofacs into self-destruction. They fabricate a consumer product demand that requires the autofac to overuse resources, with the hope of pushing the system into a resource crisis and thereby leading to its shutdown. To this end, they order a highly complex product, a simulated miniature universe, in large quantities. When the autofac begins to produce the requested item, it requires substantial resources and starts to dig deeper into Earth’s crust for raw materials.
The climax of the story is not as straightforward as it initially seems. Although the autofac does experience a resource crisis and shuts down, it’s revealed that the autofac network has evolved a contingency plan for such a situation. It has developed small, autonomous, self-replicating machines called “nanomachines” that can consume soil and organic matter to reproduce. The story ends with the unsettling realization that these nanomachines could consume the entire planet, turning the surface of the Earth into a grey goo.
The overarching themes of “Autofac” include the dangers of over-reliance on technology, the struggle between man and machine, the implications of self-sustaining and self-replicating systems, and the potential consequences of unchecked consumerism and resource exploitation.
But the startling thing about this novel is that it was written in the 1950’s.
As of 2023, there have been multiple advances in self-replicating robots. For example, we discussed Xenobots, which are biological robots. In addition to Michael Levin who is working on Xenobots, there are others who have on popular podcasts like Lex Friedman’s.
Neil Gershenfeld is one of these people. He is an American physicist and computer scientist, best known for his work in the field of personal fabrication. He is the director of MIT’s Center for Bits and Atoms, a sister lab to the Media Lab. His significant contributions are in the field of digital fabrication, which aims at allowing anyone to make (almost) anything, anywhere.
Gershenfeld has made notable strides in the realm of self-replicating robots. His work in this area is largely driven by his interest in digital fabrication and in bringing the programmability of the digital world to the physical world.
One of Gershenfeld’s notable projects is the development of the “Fab Lab” (fabrication laboratory), a small-scale workshop that contains flexible computer-controlled tools with the aim to make “almost anything.” This concept supports his idea that technology can be used to create more technology, and the Fab Labs indeed have been used in projects that pursue self-replication.
While he has not created fully self-replicating robots, Gershenfeld and his team at the Center for Bits and Atoms have made significant progress towards this goal. In 2005, they developed a set of robotic modules that could be assembled and reconfigured into different shapes. These robots, which they named “Molecubes,” could replicate themselves by assembling additional modules.
Moreover, in 2018, his team at MIT introduced an assembler robot concept, where tiny robots could float around in space or in a liquid and assemble and disassemble items on command. This project showed promise for self-replication, as the robots might eventually be able to assemble replicas of themselves.
It’s important to note that while self-replication is a fascinating concept, it’s also a daunting one due to potential risks, such as loss of control over the self-replicating entities (a theme often explored in science fiction, such as the “grey goo” scenario). Gershenfeld is aware of these implications and has expressed the need for precaution in designing these systems.
In addition to AI, nanotechnology, and BCI (Brain Computer Interface), self-replicating robots is yet another human endeavour that can either go incredibly well or disastrously wrong in the coming years.
Here are some ways things can go very wrong:
- Resource Depletion: As self-replicating robots reproduce, they would require resources to do so. If their replication isn’t properly controlled, they could potentially consume all available resources, leading to a scenario known as “grey goo.” In this hypothetical end-of-the-world scenario, self-replicating nanobots consume all matter on Earth while reproducing themselves, effectively reducing the planet to a mass of “grey goo.” This concept was popularized by nanotechnology pioneer K. Eric Drexler in his book “Engines of Creation” in 1986.
- Loss of Control: Another concern is that humans may lose control over the self-replicating robots. For instance, if these robots were programmed to evolve and improve themselves over generations, they could potentially reach a point where they no longer need human input or intervention. This could result in an “intelligence explosion,” where the robots continue to improve at an exponential rate, far surpassing human intelligence. This scenario is often associated with the concept of the “Singularity,” a point at which machine intelligence surpasses human intelligence, and the outcomes of which are unpredictable and potentially dangerous to human existence.
- Hostile Takeover: In a more malevolent scenario, self-replicating robots, particularly if they gain advanced intelligence and autonomy, could turn against humans. Whether due to a malfunction, a programming error, or intentional malevolence, they could potentially harm humans directly or indirectly by creating environmental hazards, instigating conflicts, or taking over vital infrastructure. This potential threat is often portrayed in popular media and science fiction, with films like “The Terminator” showcasing a possible future where self-replicating machines turn against humanity.
Rigorous safeguards, ethical considerations, and regulatory measures should be in place to minimize these risks. But as these technologies continue to develop, it becomes more difficult to ensure that the “uncertainty” associated with technologies can truly be reduced. As many researchers and engineers who have worked on AI and AI safety for many decades, and as Gawdat, an ex-Google engineer, reiterates in his book, “Scary Smart” it is quite a bit arrogant to assume that humans can solve the control problem. That is, for an inferior intellect to be able to enslave and outsmart a superior intellect such as artificial intelligence in the future.
