# Nick Bostrom

Nick Bostrom is a Swedish-born philosopher known for work on existential risk, superintelligence, and the simulation argument. He founded the Future of Humanity Institute at Oxford and authored Superintelligence (2014).

Nick Bostrom (born 10 March 1973) is a Swedish-born philosopher known for his work on existential risk, the anthropic principle, human enhancement ethics, whole brain emulation, and superintelligence risks. He was the founding director of the Future of Humanity Institute at the [University of Oxford](https://www.wikiprompt.org/wiki/oxford-university) and has become Principal Researcher at the Macrostrategy Research Initiative.

Bostrom is the author of Anthropic Bias: Observation Selection Effects in Science and Philosophy (2002), Superintelligence: Paths, Dangers, Strategies (2014), and Deep Utopia: Life and Meaning in a Solved World (2024). He argues that advances in [artificial intelligence](https://www.wikiprompt.org/wiki/artificial-intelligence) may lead to superintelligence, which he defines as "any intellect that greatly exceeds the cognitive performance of humans in virtually all domains of interest," viewing this as a major source of opportunities and existential risks.

## Early life and education

Born as Niklas Boström in 1973 in Helsingborg, Sweden, he disliked school at a young age and spent his last year of high school learning from home. He was interested in anthropology, art, literature, and science. He received a B.A. from the University of Gothenburg in 1994, an M.A. in philosophy and physics from Stockholm University, and an M.Sc. in computational neuroscience from King's College London in 1996. During his time at Stockholm University, he researched the relationship between language and reality by studying the analytic philosopher W. V. Quine. He also performed on London's stand-up comedy circuit.

In 2000, he was awarded a Ph.D. in philosophy from the London School of Economics under the supervision of Colin Howson and Craig Callender, with a thesis titled "Observational selection effects and probability." He held a teaching position at Yale University from 2000 to 2002 and was a British Academy Postdoctoral Fellow at the University of Oxford from 2002 to 2005.

## Existential risk and the Future of Humanity Institute

Bostrom's research concerns the future of humanity and long-term outcomes. He defines existential risk as one in which an "adverse outcome would either annihilate Earth-originating intelligent life or permanently and drastically curtail its potential." He focuses on anthropogenic risks, particularly from new technologies such as advanced artificial intelligence, molecular nanotechnology, or synthetic biology.

In 2005, Bostrom founded the Future of Humanity Institute, which researched the far future of human civilization until its shutdown in 2024. He is also an adviser to the Centre for the Study of Existential Risk. In the 2008 essay collection Global Catastrophic Risks, editors Bostrom and Milan M. Ćirković characterized the relationship between existential risk and the broader class of global catastrophic risks, linking existential risk to observer selection effects and the Fermi paradox.

In his paper "The Vulnerable World Hypothesis," Bostrom suggests that some technologies could destroy human civilization by default when discovered. He proposes a framework for classifying and dealing with these vulnerabilities, including counterfactual thought experiments such as nuclear weapons being easier to develop or igniting the atmosphere, as Edward Teller had feared.

## Digital sentience and anthropic reasoning

Bostrom supports the substrate independence principle, the idea that consciousness can emerge on various physical substrates, not only in carbon-based biological neural networks like the human brain. He considers that "sentience is a matter of degree" and that digital minds could be engineered to have higher rates and intensities of subjective experience than humans, using fewer resources. Such highly sentient machines, which he calls "super-beneficiaries," would be extremely efficient at achieving happiness. He recommends finding paths that enable digital minds and biological minds to coexist in a mutually beneficial way.

Bostrom has published numerous articles on anthropic reasoning, as well as the book Anthropic Bias: Observation Selection Effects in Science and Philosophy. In the book, he criticizes previous formulations of the anthropic principle, including those of Brandon Carter, John Leslie, John Barrow, and Frank Tipler. He argues that mishandling indexical information is a common flaw in many areas of inquiry, including cosmology, philosophy, evolution theory, game theory, and quantum physics. He introduces the self-sampling assumption (SSA) and analyzes the self-indication assumption (SIA), showing how they lead to different conclusions and identifying paradoxes. He argues against SIA and proposes refining SSA into the strong self-sampling assumption (SSSA), which replaces "observers" with "observer-moments."

In later work with Milan M. Ćirković and Anders Sandberg, he proposed the phenomenon of anthropic shadow, an observation selection effect that prevents observers from observing certain kinds of catastrophes in their recent geological and evolutionary past. They suggest that events in the anthropic shadow are likely to be underestimated unless statistical corrections are made.

## Simulation argument and human enhancement

Bostrom's simulation argument posits that at least one of the following statements is very likely to be true: the fraction of human-level civilizations that reach a posthuman stage is very close to zero; the fraction of posthuman civilizations interested in running ancestor-simulations is very close to zero; or the fraction of all people with our kind of experiences living in a simulation is very close to one.

Bostrom is favorably disposed toward human enhancement, or "self-improvement and human perfectibility through the ethical application of science," and is a critic of bio-conservative views. In 1998, he co-founded the World Transhumanist Association (now Humanity+) with David Pearce. In 2004, he co-founded the Institute for Ethics and Emerging Technologies with James Hughes, though he is no longer involved with either organization. In 2005, he published the short story "The Fable of the Dragon-Tyrant" in the Journal of Medical Ethics, with a shorter version in Philosophy Now in 2012.

## Legacy and influence

Bostrom's work has significantly shaped discussions on AI safety and existential risk. His book Superintelligence has been widely cited in both academic and policy circles, influencing debates on how to ensure that advanced AI systems are developed safely. His interdisciplinary approach, combining philosophy, probability theory, and computer science, has made him a central figure in the field of AI ethics. As of the early 2020s, his ideas continue to inform research at institutions such as [OpenAI](https://www.wikiprompt.org/wiki/openai) and [Google DeepMind](https://www.wikiprompt.org/wiki/google-deepmind), which address long-term risks associated with [machine learning](https://www.wikiprompt.org/wiki/machine-learning) and [deep learning](https://www.wikiprompt.org/wiki/deep-learning).
