In 1981, Frank Tipler [4] put forth an argument that extraterrestrial intelligences do not exist, based on the fact that von Neumann probes have not been observed. Given even a moderate rate of replication and the history of the galaxy, such probes should already be common throughout space and thus, we should have already encountered them.
The Berserker hypothesis, also known as the deadly probes scenario, is the idea that humans have not yet detected intelligent alien life in the universe because it has been systematically destroyed by a series of lethal Von Neumann probes. [1] [2] The hypothesis is named after the Berserker series of novels (1963–2005) written by Fred ...
The Hart–Tipler conjecture is the idea that an absence of detectable Von Neumann probes is contrapositive evidence that no intelligent life exists outside of the Solar System. [1] [2] This idea was first proposed in opposition to the Drake equation in a 1975 paper by Michael H. Hart titled "Explanation for the Absence of Extraterrestrials on ...
In Arthur C. Clarke's novel The Fountains of Paradise the extraterrestrial Starglider probe is an example of a Bracewell probe. In Clarke's story "The Sentinel", later adapted into the film 2001: A Space Odyssey, the 'Monolith' appears to be a Bracewell probe placed on the Moon to ensure that only a civilization capable of spaceflight would be able to discover it.
John von Neumann (/ v ɒ n ˈ n ɔɪ m ən / von NOY-mən; Hungarian: Neumann János Lajos [ˈnɒjmɒn ˈjaːnoʃ ˈlɒjoʃ]; December 28, 1903 – February 8, 1957) was a Hungarian and American mathematician, physicist, computer scientist and engineer.

This idea underlies the concept of the Von Neumann probe and the Bracewell probe as a potential evidence of extraterrestrial intelligence. It is possible, however, that present scientific knowledge cannot properly gauge the feasibility and costs of such interstellar colonization.
Investigations of cases where artificial intelligence (AI) is used to break the law will be streamlined under a new process approved by the U.S. Federal Trade Commission, the agency said on Tuesday.
