Nick Bostrom ( ; ; born 10 March 1973)
Bostrom is the author of (2002), (2014) and Deep Utopia: Life and Meaning in a Solved World (2024).
Bostrom believes that advances in artificial intelligence (AI) may lead to superintelligence, which he defines as "any intellect that greatly exceeds the cognitive performance of humans in virtually all domains of interest". He views 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 a wide variety of academic areas, including anthropology, art, literature, and science.
He received a B.A. degree from the University of Gothenburg in 1994.
Research and writing
Existential risk
Bostrom's research concerns the future of humanity and long-term outcomes.
He discusses
existential risk,
which he defines as one in which an "adverse outcome would either annihilate Earth-originating intelligent life or permanently and drastically curtail its potential". Bostrom is mostly concerned about anthropogenic risks, which are risks arising from human activities, particularly from new technologies such as advanced artificial intelligence, molecular nanotechnology, or synthetic biology.
In 2005, Bostrom founded the Future of Humanity Institute which,
In the 2008 essay collection, Global Catastrophic Risks, editors Bostrom and Milan M. Ćirković characterize the relationship between existential risk and the broader class of global catastrophic risks, and link existential risk to observer selection effects
Vulnerable world hypothesis
In a paper called "The Vulnerable World Hypothesis",
Bostrom suggests that there may be some technologies that destroy human civilization by default when discovered. Bostrom proposes a framework for classifying and dealing with these vulnerabilities. He also gives counterfactual thought experiments of how such vulnerabilities could have historically occurred, e.g. if nuclear weapons had been easier to develop or had ignited the atmosphere (as
Edward Teller had feared).
Digital sentience
Bostrom supports the substrate independence principle, the idea that consciousness can emerge on various types of 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 can in theory be engineered to have a much higher rate and intensity of subjective experience than humans, using less resources. Such highly sentient machines, which he calls "super-beneficiaries", would be extremely efficient at achieving happiness. He recommends finding "paths that will enable digital minds and biological minds to coexist, in a mutually beneficial way where all of these different forms can flourish and thrive".
Anthropic reasoning
Bostrom has published numerous articles on anthropic reasoning, as well as the book
. In the book, he criticizes previous formulations of the anthropic principle, including those of
Brandon Carter, John Leslie, John Barrow, and Frank Tipler.
Bostrom believes that the mishandling of indexical information is a common flaw in many areas of inquiry (including cosmology, philosophy, evolution theory, game theory, and quantum physics). He argues that an anthropic theory is needed to deal with these. He introduces the self-sampling assumption (SSA) and analyzes the self-indication assumption (SIA), shows how they lead to different conclusions in a number of cases, and identifies how each is affected by paradoxes or counterintuitive implications in certain thought experiments. He argues against SIA and proposes refining SSA into the strong self-sampling assumption (SSSA), which replaces "observers" in the SSA definition with "observer-moments".
In later work, he proposed with Milan M. Ćirković and Anders Sandberg 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 that lie in the anthropic shadow are likely to be underestimated unless statistical corrections are made.
Simulation argument
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 that are interested in running ancestor-simulations is very close to zero;
-
The fraction of all people with our kind of experiences that are living in a simulation is very close to one.
Ethics of human enhancement
Bostrom is favorably disposed toward "human enhancement", or "self-improvement and human perfectibility through the ethical application of science", as well as a critic of bio-conservative views.
In 1998, Bostrom co-founded (with David Pearce) the World Transhumanism Association
In 2005, Bostrom published the short story "The Fable of the Dragon-Tyrant" in the Journal of Medical Ethics. A shorter version was published in 2012 in Philosophy Now.
With philosopher Toby Ord, he proposed the reversal test in 2006. Given humans' irrational status quo bias, how can one distinguish between valid criticisms of proposed changes in a human trait and criticisms merely motivated by resistance to change? The reversal test attempts to do this by asking whether it would be a good thing if the trait was altered in the opposite direction.
Bostrom's work also considers potential Dysgenics effects in human populations but he thinks genetic engineering can provide a solution and that "In any case, the time-scale for human natural genetic evolution seems much too grand for such developments to have any significant effect before other developments will have made the issue moot".
Technology strategy
Bostrom has suggested that technology policy aimed at reducing existential risk should seek to influence the order in which various technological capabilities are attained, proposing the principle of differential technological development. This principle states that we ought to retard the development of dangerous technologies, particularly ones that raise the level of existential risk, and accelerate the development of beneficial technologies, particularly those that protect against the existential risks posed by nature or by other technologies.
In 2011, Bostrom founded the Oxford Martin Program on the Impacts of Future Technology.
Bostrom's theory of the unilateralist's curse has been cited as a reason for the scientific community to avoid controversial dangerous research such as reanimating pathogens.
Books
Superintelligence: Paths, Dangers, Strategies
In 2014, Bostrom published
, which became a
New York Times Best Seller.
The book argues that superintelligence is possible and explores different types of superintelligences, their cognition, the associated risks. He also presents technical and strategic considerations on how to make it safe.
Characteristics of a superintelligence
Bostrom explores multiple possible paths to superintelligence, including
Mind uploading and human intelligence enhancement, but focuses on artificial general intelligence, explaining that electronic devices have many advantages over biological brains.
Bostrom draws a distinction between final goals and instrumental goals. A final goal is what an agent tries to achieve for its own intrinsic value. Instrumental goals are just intermediary steps towards final goals. Bostrom contends there are instrumental goals that will be shared by most sufficiently intelligent agents because they are generally useful to achieve any objective (e.g. preserving the agent's own existence or current goals, acquiring resources, improving its cognition...), this is the concept of instrumental convergence. On the other side, he writes that virtually any level of intelligence can in theory be combined with virtually any final goal (even absurd final goals, e.g. making paperclips), a concept he calls the orthogonality thesis.
He argues that an AI with the ability to improve itself might initiate an intelligence explosion, resulting (potentially rapidly) in a superintelligence.
Bostrom argues that giving simplistic final goals to a superintelligence could be catastrophic:
Mitigating the risk
Bostrom explores several pathways to reduce the existential risk from AI. He emphasizes the importance of international collaboration, notably to reduce race to the bottom and AI arms race dynamics. He suggests potential techniques to help control AI, including containment, stunting AI capabilities or knowledge, narrowing the operating context (e.g. to question-answering), or "tripwires" (diagnostic mechanisms that can lead to a shutdown).
But Bostrom contends that "we should not be confident in our ability to keep a superintelligent genie locked up in its bottle forever. Sooner or later, it will out". He thus suggests that in order to be safe for humanity, superintelligence must be
AI alignment with morality or human values so that it is "fundamentally on our side".
Potential AI
normativity frameworks include Yudkowsky's coherent extrapolated volition (human values improved via extrapolation),
Morality (doing what is morally right), and moral permissibility (following humanity's coherent extrapolated volition except when it's morally impermissible).
Bostrom warns that an existential catastrophe can also occur from AI being misused by humans for destructive purposes, or from humans failing to take into account the potential moral status of digital minds. Despite these risks, he says that machine superintelligence seems involved at some point in "all the plausible paths to a really great future".
Public reception
The book became a
New York Times Best Seller and received positive feedback from personalities such as
Stephen Hawking,
Bill Gates,
Elon Musk,
Peter Singer and
Derek Parfit. It was praised for offering clear and compelling arguments on a neglected yet important topic. It was sometimes criticized for spreading pessimism about the potential of AI, or for focusing on longterm and speculative risks.
Some skeptics such as
Daniel Dennett or
Oren Etzioni contended that superintelligence is too far away for the risk to be significant.
considers that there is no existential risk, asserting that superintelligent AI will have no desire for self-preservation
and that experts can be trusted to make it safe.
Raffi Khatchadourian wrote that Bostrom's book on superintelligence "is not intended as a treatise of deep originality; Bostrom's contribution is to impose the rigors of analytic philosophy on a messy corpus of ideas that emerged at the margins of academic thought."
Deep Utopia: Life and Meaning in a Solved World
In his 2024 book,
Deep Utopia: Life and Meaning in a Solved World, Bostrom explores the concept of an ideal life, if humanity transitions successfully into a post-superintelligence world. Bostrom notes that the question is "not how interesting a future is to look at, but how good it is to live in." He outlines some technologies that he considers physically possible in theory and available at technological maturity, such as cognitive enhancement, reversal of aging, arbitrary sensory inputs (taste, sound...), or the precise control of motivation, mood, well-being and personality. According to him, not only machines would be better than humans at working, but they would also undermine the purpose of many leisure activities, providing extreme welfare while challenging the quest for meaning.
Public engagement
Bostrom has provided policy advice and consulted for many governments and organizations. He gave evidence to the House of Lords, Select Committee on Digital Skills.
He is an advisory board member for the Machine Intelligence Research Institute,
Future of Life Institute,
and an external advisor for the Cambridge Centre for the Study of Existential Risk.
1996 email incident
In January 2023, Bostrom issued an apology
for a 1996
LISTSERV email
he sent as a postgrad where he had stated that he thought "Blacks are more stupid than whites", and where he also used the word "
" in a description of how he thought this statement might be perceived by others.
The apology, posted on his website,
stated that "the invocation of a racial slur was repulsive" and that he "completely repudiated this disgusting email".
The email has been described as "racist" in several news sources.
Shortly afterward, Oxford University condemned the language used in the email and started an investigation.
Personal life
Bostrom met his wife Susan in 2002. As of 2015, she lived in
Montreal and Bostrom in Oxford. They have one son.
