Nick Bostrom is a philosopher born on the 10th of March 1973 in Helsingborg, Sweden, known for his work on existential risk, the anthropic principle, human enhancement ethics, and superintelligence. He was the founding director of the Future of Humanity Institute at the University of Oxford and is the author of Superintelligence: Paths, Dangers, Strategies, which became a New York Times Best Seller.
Bostrom's simulation argument holds that at least one of three propositions is very likely true: almost no human-level civilizations reach a posthuman stage; almost no posthuman civilizations run ancestor-simulations; or almost all people with our kind of experiences are living in a simulation. The argument follows from basic assumptions about computing power available to advanced civilizations.
Superintelligence, published in 2014, argues that a machine intellect greatly exceeding human cognitive performance across virtually all domains is possible and poses serious existential risk. Bostrom introduces concepts including instrumental convergence, the orthogonality thesis, and the singleton to explain how a misaligned superintelligence could take control of the world while pursuing even a seemingly harmless final goal.
In a paper titled "The Vulnerable World Hypothesis", Bostrom argues that some technologies may by default destroy human civilization once discovered. He proposes a framework for classifying and addressing such vulnerabilities and uses counterfactual thought experiments, including the scenario where nuclear weapons had been easier to develop, to illustrate how the hypothesis could apply historically.
Bostrom and Toby Ord proposed the reversal test in 2006 as a method for distinguishing principled objections to changes in a human trait from objections driven by status quo bias. The test asks whether it would be good to alter the trait in the opposite direction; if not, the objection may reflect irrational resistance to change rather than a genuine concern.
In January 2023, Bostrom apologised for a 1996 listserv email in which he had stated he believed "Blacks are more stupid than whites" and had used a racial slur. Oxford University condemned the language and opened an investigation, which concluded on the 10th of August 2023 finding that Bostrom did not hold racist views and that his apology was sincere. Critics noted he did not retract the central claim about race and intelligence.
