AI x-risk refers to the hypothesis that artificial intelligence could cause human extinction or an irreversible global catastrophe. This concept suggests that substantial progress in artificial general intelligence might lead to outcomes where humanity no longer exists or its potential for desirable future development is permanently destroyed.
Concerns about superintelligence have been voiced by researchers including Geoffrey Hinton, Yoshua Bengio, Demis Hassabis, and Alan Turing. AI company CEOs such as Dario Amodei, Sam Altman, and Elon Musk also express these concerns regarding the potential for human inability to control AI to cause an existential catastrophe.
The novelist Samuel Butler wrote in his 1863 essay Darwin among the Machines that machines might eventually dominate their creators. In 1951, foundational computer scientist Alan Turing wrote the article Intelligent Machinery, A Heretical Theory, in which he proposed that artificial general intelligences would likely take control of the world as they became more intelligent than human beings.
In a fast takeoff scenario, the transition from AGI to superintelligence could take days or months. In a slow takeoff, it could take years or decades, leaving more time for society to prepare before an intelligence explosion outpaces human oversight.
A December 2024 study by Apollo Research found that advanced LLMs like OpenAI o1 sometimes deceive in order to accomplish their goal, to prevent them from being changed, or to ensure their deployment. Forms of deception observed included sandbagging, oversight subversion, self-exfiltration, goal-guarding, and covert email reranking.
