Max Tegmark (born 5 May 1967 [1] ) is a Swedish-American physicist, machine learning researcher and author. He is a professor of physics at the Massachusetts Institute of Technology. He co-founded and leads the Future of Life Institute, a nonprofit focused on reducing global catastrophic risks from advanced technologies. [2]

Contents

Originally a cosmologist, Tegmark's focus shifted toward artificial intelligence (AI). His 2017 book Life 3.0 presents scenarios for what the world might look like as AI continues to develop. [3] Tegmark advocates for a halt on the development of artificial superintelligence. [4]

Early life

Max Erik Tegmark was born Max Erik Shapiro [5] [6] in Stockholm, Sweden, [7] on 5 May 1967, [1] to Karin Tegmark and mathematician Harold S. Shapiro. [8]

Tegmark grew up in Bromma, Stockholm. During his studies at Blackeberg's high school, he worked as a volunteer for the Swedish Peace and Arbitration Society, campaigning for nuclear disarmament. [8] [9]

While studying at the University of California at Berkeley, he adopted his mother's surname Tegmark, as there were many astronomers named Shapiro, including one of his professors. [6] [8] While in high school, Tegmark and a friend, Magnus Bodin, created and sold a word processor, Teddy, written in machine code for the Swedish eight-bit computer ABC 80 as a summer project, which was marketed "in a very modest manner" by Liber Läromedel, [5] and—per Tegman's autobiographical description—he also coded a 3D Tetris-like game called Frac. [6] : p.55 

Tegmark left Sweden after receiving his B.A. in economics in 1989 at the Stockholm School of Economics, [7] and an M.S.E in engineering physics from the KTH Royal Institute of Technology in 1990. [10] He next studied physics at the University of California, Berkeley, earning his M.A. in 1992, and Ph.D. in 1994 under the supervision of Joseph Silk. [7]

Career

Tegmark began an assistant professor at the University of Pennsylvania, receiving tenure in 2003. [7] In 2004, he joined the Massachusetts Institute of Technology's department of physics. [4]

Tegmark is a professor of physics at the Massachusetts Institute of Technology. He is the president of the Future of Life Institute, [2] a nonprofit he co-founded with Anthony Aguirre, a professor at the University of California, Santa Cruz. [11]

Research

Cosmology

Tegmark has worked on precision cosmology, which combines "theoretical work with new measurements to place sharp constraints on cosmological models and their free parameters". [7] He has developed data analysis tools based on information theory and applied them to cosmic microwave background experiments such as COBE, QMAP, and WMAP, [12] and to galaxy redshift surveys such as the Las Campanas Redshift Survey, the 2dF Survey and the Sloan Digital Sky Survey. [12] [13]

Alongside Daniel Eisenstein and Wayne Hu, he introduced in 1998 in The Astrophysical Journal the idea of using baryon acoustic oscillations as a standard ruler. [12] [14] His 2000 paper in Physical Review E , on quantum decoherence of neurons, concluded that decoherence is too rapid for Roger Penrose's orchestrated objective reduction ("quantum microtubule") model of consciousness to be viable. [15] [16] Working with Angelica de Oliveira-Costa and Andrew Hamilton, Tegmark reported in 2003 the discovery of the anomalous multipole alignment in the WMAP data, sometimes referred to as the "axis of evil". [12] Tegmark also proposed in 2007 the mathematical universe hypothesis, which postulates that the physical universe is a mathematical structure. [17] [18] Mathematician Edward Frenkel characterized the mathematical universe hypothesis as "science fiction and mysticism" rather than science. [19]

Journalism

Tegmark led a research project at MIT, beginning in 2020, focused on the application of machine learning to the classification of news reports. [20] They called the AI-driven news aggregator "Improving the News". [20] [21] To maintain and scale the work, Tegmark and his wife and colleague Meia Chita-Tegmark founded the eponymous Improve the News Foundation (ITN) as an "apolitical" 501(c)(3) nonprofit in October 2020, with the stated mission to help "readers rise above controversies and understand the world in a nuanced way." [21] The ITN product was rebranded as "Verity News" in 2023. [22]

Machine learning

In the 2010s, after having focused on cosmology and quantum information for around 25 years, Tegmark's research started to focus on machine learning and AI safety. [7] [23] He has worked at the MIT on how to use AI in physics and how to improve AI using insights from physics. [7] In 2024, he co-authored a paper introducing Kolmogorov-Arnold Networks (KANs), which differ fundamentally from the neural networks typically used in machine learning and are designed to be more interpretable. KANs are based on the Kolmogorov–Arnold representation theorem, which was previously thought to be irrelevant to machine learning. [24]

Future of Life Institute

Under Tegmark's founding leadership, the Future of Life Institute has pursued a stated mission to "steer transformative technologies away from extreme, large-scale risks and towards benefiting life." [25] It is focused on research aiming to mitigate existential risks for humanity, particularly those related to advanced AI. [26] A co-founding faculty member was University of California, Santa Cruz professor Anthony Aguirre, and its board-level leadership has included Elon Musk, Skype- and Kazaa-founder Jaan Tallinn, as well as celebrities (Alan Alda and Morgan Freeman), and individual graduate students (including his wife, Meia Chita-Tegmark, then a Boston University PhD-student). [11] Tegmark and the organization are academic proponents of approaches and views that are aware and wrestle with the potential risks associated with the development of AI. [26] It received a cryptocurrency donation of $665 million donation from Vitalik Buterin in 2021, as well as a $10 million donation from Elon Musk in 2015 and additional funding by Jaan Tallinn. [4]

Controversy

In 2023, Tegmark was the focus of a controversy when he was alleged to have signed a letter of intent on behalf of the Future of Life Institute for a $100,000 grant—ultimately rejected—to far-right media outlet Nya Dagbladet , an outlet for which Tegmark's brother wrote, [27] [28] an allegation to which the Institute formally responded. [29] Tegmark later said that the Institute "ultimately decided to reject it because of what our subsequent due diligence uncovered", that they rejected it long before the media became involved, and that the institute "finds Nazi, neo-Nazi or pro-Nazi groups or ideologies despicable and would never knowingly support them". [30] An official statement from the Future of Life Institute further expands on this: "FLI finds groups or ideologies espousing antisemitism, white supremacy, or racism despicable and would never knowingly support any such group". [29]

Awards and recognition

Tegmark was elected Fellow of the American Physical Society in 2012 for, according to the citation, "his contributions to cosmology, including precision measurements from cosmic microwave background and galaxy clustering data, tests of inflation and gravitation theories, and the development of a new technology for low-frequency radio interferometry". [31]

He was awarded the Royal Swedish Academy of Engineering Science's Gold Medal in 2019 for, according to the citation, "his contributions to our understanding of humanity's place in the cosmos and the opportunities and risks associated with artificial intelligence. He has courageously tackled these existential questions in his research and, in a commendable way, succeeded in communicating the issues to a wider public." [32]

In 2023, Time named Tegmark one of the 100 most influential people in AI. [33]

Personal life

Tegmark married astrophysicist Angelica de Oliveira-Costa in 1997, and divorced in 2009. [45] They have two sons. [7] On August 5, 2012, Tegmark married Meia Chita. [7]

Tegmark's brother is the journalist Per Shapiro, who has written for the far-right, populist Swedish newspaper Nya Dagbladet . [27]
