Lex Fridman

Fridman was born Alexey Alexandrovich Fridman in the Soviet Union in 1983; his father, Alexander Fridman, is a noted plasma physicist. When he was about 11, the family moved to the Chicago area in the United States.⁠[1]

In a June 2023 episode he said he was born in Chkalovsk, a town in Tajikistan now called Buston, not the Russian town of the same name, and that his father was born in Kyiv, Ukraine.⁠[2]

He has said that his parents were born in Kyiv and Kharkiv; he lived for a time in Tajikistan, then in Kyiv and Moscow, before moving to the United States.⁠[3]

He has mentioned that his grandmother lived through the Holodomor famine before World War II and then through Nazi-occupied Ukraine.⁠[4]

He has also said that, growing up in the Soviet Union, he heard stories of war heroes, and that his grandfather was a machine gunner who “miraculously survived” World War II.⁠[5]

He has recalled that one of the first things he noticed after immigrating from the Soviet Union to the United States was “how plentiful bananas and pineapples were” in the produce section.⁠[6]

He earned all three of his degrees at Drexel University in Philadelphia, a BS and MS in computer science in 2010 and a PhD in electrical and computer engineering in 2014.⁠[7]

He has said that during his studies he did many “non-standard things”: he trained and competed in judo and jiu-jitsu throughout his 20s, wrote poetry, read history and philosophy, and played guitar in bars.⁠[8]

His doctoral dissertation, “Learning of Identity from Behavioral Biometrics for Active Authentication,” was supervised by Moshe Kam and Steven Patrick Weber and studied identifying users from behavioral biometrics.⁠[9]

After Drexel he spent six months at GoogleGoogleGoogle is an American technology company founded by Larry Page and Sergey Brin and incorporated in 1998. It became an Alphabet subsidiary in 2015. Its businesses include internet search, advertising, software platforms, cloud computing, and artificial intelligence.Open the full entry continuing his doctoral authentication work, then accepted a research scientist position at MIT.⁠[7]

In 2015, after a short stint at Google, he joined the Massachusetts Institute of Technology (MIT) as a research scientist, initially working at AgeLab, a lab focused on the health and care of older people.⁠[10]

His MIT page lists him as an MIT research scientist since 2015, now at the Laboratory for Information and Decision Systems (LIDS), working on human-AI interaction, robotics and machine learning.⁠[11]

His MIT lectures are collected by year; the 2017 set includes “Introduction to Deep Learning and Self-Driving Cars” and other talks, followed by 2018–2020 lectures on the state of the art in deep learning, reinforcement learning, self-driving cars and guest talks.⁠[12]

His paper with Bryan Reimer and others, “What can be predicted from six seconds of driver glances?”, won a Best Paper Award at the ACMAustralian Community MediaAustralian Community Media (ACM) is an Australian regional and rural news publishing group with more than 100 brands, including The Canberra Times; in 2019 Nine sold it to a company controlled by interests associated with Antony Catalano and Thorney Investment Group.Open the full entry CHI 2017 conference in Denver in May 2017; in 2018 he and co-authors including William T. Freeman presented “Cognitive load estimation in the wild” at CHI.⁠[13]

In describing AgeLab’s collaboration with the Toyota Collaborative Safety Research Center (CSRC), MIT noted that computer scientist Fridman was leading a group of seven engineers working on computer vision, deep learning and planning algorithms for semi-autonomous vehicles.⁠[14]

As lead author he posted the MIT Advanced Vehicle Technology (MIT-AVT) study paper on arXiv, describing instrumented vehicles, including 23 Tesla Model S and Model X cars, used for long-term naturalistic driving data collection; the abstract listed 122 participants, 511,638 miles and 7.1 billion video frames to date.⁠[15]

The paper was later published in IEEE Access, volume 7, in 2019.⁠[13]

In early 2018 he taught MIT 6.S094, “Deep Learning for Self-Driving Cars,” alongside a new course, 6.S099, “Artificial General Intelligence.” He said the lectures would be released online and that “It’s important to me to make this course free and open to everyone.”⁠[16]

On his birthday he posted a video of himself playing the guitar solo from Pink Floyd’s “Comfortably Numb,” writing that “Writing and playing music has been a creative refuge for me throughout my life.”⁠[17]

The first episode in the show’s official RSS feed was published on August 26, 2018, featuring MIT physics professor Max TegmarkMax TegmarkMax Tegmark is an MIT physics professor and AI researcher who worked on precision cosmology and proposed the Mathematical Universe Hypothesis; in 2014 he founded the Future of Life Institute, which works to reduce risks from AI and other technologies, and he wrote Our Mathematical Universe and Life 3.0. He has appeared three times on the Lex Fridman Podcast and was its first guest.Open the full entry and his book “Life 3.0.”⁠[18]

The podcast began as part of his course on artificial general intelligence and was first called the Artificial Intelligence Podcast, using in-person long-form interviews that typically last two to four hours.⁠[19]

Opening episode 14, a conversation with Kyle Vogt, he described it as “part of the MIT Artificial General Intelligence series and the Artificial Intelligence podcast.”⁠[20]

After nine years of training and competing, he received his Brazilian jiu-jitsu black belt from Phil Migliarese and Ricardo Migliarese at Balance Studios. He wrote that the biggest lesson was that “I’m not special, far from it,” adding, “There are no shortcuts.”⁠[21]

He has said, “I wrestled my whole life, judo, jujitsu”; by 2023 he held a first-degree black belt in Brazilian jiu-jitsu.⁠[22][23]

In early April 2019 an MIT team released a paper analyzing Tesla drivers’ use of Autopilot with MIT-AVT data, concluding that drivers maintained a “high degree of functional vigilance”; the data covered about 520,000 km of driving, about 34.8 percent of it under Autopilot control.⁠[24]

Auto industry writer Edward Niedermeyer questioned the sample of Fridman’s paper: short-term participants drove MIT-owned cars after extra screening and training, while long-term participants were recruited from Tesla owner forums. He also criticized Elon MuskElon MuskElon Musk is an entrepreneur who founded SpaceX and has long served as chief executive of Tesla; he also took part in creating PayPal, OpenAI, Neuralink, The Boring Company, and xAI. He acquired Twitter in 2022, and his businesses span spaceflight, electric vehicles, energy, artificial intelligence, and social media.Open the full entry for quoting the study selectively on Twitter and noted that Fridman had blocked NVIDIANVIDIANVIDIA is an American semiconductor and computing technology company that provides graphics processing units, artificial intelligence infrastructure, networking interconnects, and computing software, and is listed on Nasdaq under the ticker NVDA.Open the full entry research director Anima Anandkumar after she suggested he pursue peer review.⁠[25]

Niedermeyer and his co-hosts discussed the “considerable controversy” around the study on an automotive technology show, noting that its finding ran against existing research on complacency and distraction when humans supervise partial automation.⁠[26]

On April 12, 2019, the podcast released its first conversation with Elon Musk, titled “Elon Musk: Tesla Autopilot.”⁠[27]

Musk returned four more times, on November 12, 2019, December 28, 2021, November 9, 2023, and August 2, 2024 (with the Neuralink team).⁠[18]

On August 19, 2020, he announced that the Artificial Intelligence Podcast was being renamed the Lex Fridman Podcast, explaining that “AI is still my passion, but this gives me a bit more freedom to talk to folks outside AI,” in tech, science, physics, philosophy and history.⁠[28]

He released the solo episode “In Memory of My Grandmother,” saying that she “taught me how to be a man, taught me about strength, about wisdom, about compassion, about love.”⁠[29]

In 2021 he moved to Austin, Texas, to focus more on the podcast; he remained paid by MIT as a research scientist and visited campus only occasionally.⁠[30]

He released his first “Ask Me Anything” episode, answering listener questions on pivoting into computer science, how he picks guests, topics on which he changed his mind, the keto diet and the darkest time in his life; one segment was titled “Love is an escape from the muck of life.”⁠[31]

In September 2021 a group of MIT researchers published a new paper using nearly 500,000 miles of Tesla driving data from the long-term AVT study that Fridman had previously led, finding that with Autopilot active, non-driving glances down or to the center stack were the most frequent and longest, with 22 percent exceeding two seconds.⁠[32]

On February 26, 2022, the podcast released its first conversation with Meta CEO Mark Zuckerberg, covering MetaMetaMeta (Meta Platforms, Inc.) is a publicly listed American technology company, renamed from Facebook in 2021, that operates social communication, digital advertising, virtual reality, smart glasses and artificial intelligence businesses.Open the full entry, Facebook, Instagram and the metaverse.⁠[33]

After the full-scale war began he traveled to Ukraine, spending much time in Kyiv and visiting the Kherson region, where heavy fighting was under way, and spending time with Tim Kennedy; he later called the trip “in many ways, stupid and dangerous” and said most of his conversations there were in Russian.⁠[22]

In July 2023 he said the Kherson visit had taken place “a year ago in August,” adding that everyone he met was proud to fight for their country.⁠[34]

He has also said that in Ukraine he spoke Russian with almost everyone he met, including the leadership, and that for many of them Russian was the more comfortable language.⁠[4]

On October 24, 2022, the podcast released an interview with the artist Ye (Kanye West).⁠[35]

In January 2023 Nathan J. Robinson criticized Fridman’s warmth toward every guest, arguing that in the Ye interview “West was mostly just free to rant” and pointing to “a certain lack of balance” among the show’s guests.⁠[36]

AI researcher Gary Marcus wrote that the 2019 Autopilot paper was never published in a scientific journal or replicated and that Fridman no longer listed it among his publications; Marcus said three of the authors, including Fridman, did not respond to his inquiries.⁠[37]
