핵심 요약

필즈 메달 수상자 25명이 '수학 분야 AI의 심각한 정렬 오류'라는 성명을 발표하며 AI 기업의 목표가 수학 공동체의 목표와 심각하게 어긋난다고 비판했다. 그러나 저자는 수학 공동체 자체도 '개념적 이해와 통찰'이라는 목표와 정렬되어 있지 않다고 반박하며, 나비에-스토크스 문제와 관련된 유능한 수학자들이 역사적으로 어떻게 학계로부터 보호받지 못했는지를 사례로 든다.

필즈 메달 수상자 25명이 '수학 분야에서 AI의 심각한 정렬 오류(A Severe Misalignment of AI in Mathematics)'라는 서한의 최초 서명자였으며, 이들은 "AI 기업의 목표와 수학 공동체의 목표는 심각하게 어긋나 있다"고 주장했다. 그들은 옳다. 그들의 말대로 AI 기업의 목표는 "개념적 이해와 통찰이라는 주요 목표"와 일치하지 않는 것으로 보이며, 실제로 "AI 기업들의 해법은 서두르게 발표되어 제대로 된 논문 작성, 새로운 방법과 아이디어의 분리, 관련 선행 연구 인용을 할 시간적 여유를 남기지 않는다". 이는 사실이다(하지만 아이럽게도, 서명자들 자신도 "더 광범위한 협의 과정을 거칠 시간이 없어" 서한을 빠르게 공개했다고 말했다). 또한 수학 공동체의 목표 역시 "개념적 이해와 통찰이라는 주요 목표"와 일치하지 않는 것으로 보인다는 것도 사실이다. 만약 그것이 목표였다면 수학 공동체는 "이 직업의 가장 소중한 자원은 학생들과 아이디어"이며 이들을 "세심하게 보육해야 한다"는 관점을 갖고 있었을 것이기 때문에 이는 분명하다. 하지만 안타깝게도 수학의 학생들과 아이디어는 세심하게 보육되지 못했다. 필즈 메달 수상자 25명의 서한은 OpenAI가 나비에-스토크스 존재성과 매끄러움 문제의 해법을 발표한 것이 계기가 된 것으로 보이는데, 그렇다면 수학 공동체가 그 분야에서 일한 일부 학생들과 그들의 기초적인 아이디어를 어떻게 키워왔는지 살펴보자. 율리우스 샤우더(Juliusz Schauder, 르레-샤우더 차수(Leray–Schauder degree)): 샤우더는 1923년에 박사 학위를 받았지만, (수학자들에 의한) 반유대주의로 대학 교수 자리를 거부당했다. 그는 대신 진지한 수학 연구를 하며 고등학교에서 가르쳤다. 나치가 집권한 몇 년 후, 샤우더는 전 세계 수학자들에게 도움을 요청했지만 수많은 수학자들이 도움을 거절했다. 그는 프린스턴의 초빙을 받으려 했으나 거절당했다. 이는 단지 급여 문제가 아니었다. 그의 생명이 위태로웠다. 결국 그는 연구를 기록할 종이조차 구할 수 없었고 독일군에게 살해당했다. 그의 아내 에밀리아는 딸과 함께 숨어 지내며 한동안 하수도에서 살아남았다. 에밀리아는 결국 붙잡혀 강제 수용소에서 살해당했다. 이것이 "세심한 보육"이었는가? 아, 그렇지만 그건 아주 오래전 일이라고 하실 것이다! 올가 라디젠스카야(Olga Ladyzhenskaya, 라디젠스카야 부등식(Ladyzhenskaya inequality)): 1950년대 후반까지 라디젠스카야는 편미분방정식과 유체역학 분야의 선도적인 수학자였다. 1958년 그녀는 현재 라디젠스카야 부등식으로 알려진 것을 사용해 2차원 나비에-스토크스 방정식의 전역 존재성과 유일성을 증명했다. 이 연구는 나비에-스토크스 이론의 기초가 되었다. 같은 해 36세의 나이로 그녀는 필즈 메달 후보에 올랐으나 클라우스 로스와 르네 톰에게 밀렸다. 아, 그렇지만 필즈 메달은 실력 기반이라고 하실 것이다! 1958년 필즈 위원회의 기록은 그 결정이 순수하게 실력 기반이 아니었음을 보여준다. 최유력 후보였던 프리드리히 히르체부루흐는 그가 잘 나가고 있어 더 격려가 필요 없다는 이유로 탈락했으며, 위원회는 알렉산더 그로텐디크가 히르체부루흐 다음으로 가장 재능 있다는 데 동의했지만 나중에 받을 수 있을 것이라고 판단했다. 첫 여성 필즈 메달리스트인 마리암 미르자카니가 탄생하기까지는 그로부터 56년이 더 걸렸다(주목할 점은 25명의 필즈 메달 서명자 중 단 한 명만이 여성이라는 것이다). 이것이 "세심한 보육"이었는가? 아, 그렇지만 이제는 상황이 달라졌다고 하실 것이다! 카렌 울렌벡(Karen Uhlenbeck, 기하학적 해석학과 비선형 편미분방정식): 2019년 울렌벡은 최초의 여성 아벨상 수상자가 되었다. 하지만 1968년 박사 학위를 받고 MIT와 버클리에서 임시 직책을 거친 후, 울렌벡은 취업을 지원했을 때 "사람들은 여성을 고용하지 않는다"는 말과 여성은 "집에 가서 아이를 낳아야 한다"는 말을 당연하다는 듯이 들었다. MIT, 스탠퍼드, 프린스턴은 그녀의 남편에게는 관심이 있었지만 그녀에게는 관심이 없었다. 그녀는 "채용 금지 규정( nepotism rules)" 때문에 안 된다는 말을 들었다.

Twenty five Fields medalists were initial signatories of the letter " A Severe Misalignment of AI in Mathematics " in which they opine that "The goals of the AI companies and the goals of the mathematical community are severely misaligned". They are right. As they say, the goals of AI companies do not seem to be aligned with "the primary goal of conceptual understanding and insight", and indeed, the "solutions [by AI companies] are [being] announced in a rush, leaving no time for a proper writeup, the isolation of new methods and ideas, and citing relevant previous work of others." This is true (but ironically, the signatories themselves say they released their letter quickly because they “did not have the time to have a more consultative process.") It is also true that the goals of the mathematics community do not seem to be aligned with "the primary goal of conceptual understanding and insight". This is clear, because if that were the goal, then the mathematics community would hold the view that "the most precious resources of [its] profession are students and ideas", and that they would be "nurture[d] with great care". But sadly students and ideas in mathematics have not been nurtured with great care. Since the letter by the twenty five Fields medalists seems to have been precipitated by the OpenAI announcement a solution to the Navier Stokes existence and smoothness problem , let's take a look at how the mathematics community has nurtured some of the students who worked in that area, and their foundational ideas. Juliusz Schauder ( Leray–Schauder degree ): Schauder earned his doctorate in 1923, but antisemitism (by mathematicians) resulted in denial of university positions . Instead he taught high school while producing serious math. A few years later after the Nazis rose to power, Schauder asked for help from mathematicians around the world, and yet numerous mathematicians declined to help. He tried to get an invitation from Princeton and was denied. This wasn't just a matter of getting a salary. His life was in danger. Eventually he did not even have access to paper to write down his work and he was murdered by the Germans. His wife Emilia hid with their daughter, for a while living in sewers to survive. Emilia was eventually captured and then murdered in a concentration camp. Was this "nurture with great care"? Oh, you say, but this was a long time ago ! Olga Ladyzhenskaya ( Ladyzhenskaya inequality ): By the late 1950s Ladyzhenskaya was a leading mathematician in PDEs and fluid mechanics. In 1958 she proved global existence and uniqueness for the two-dimensional Navier–Stokes equations using what is now known as the Ladyzhenskaya inequality. This work became foundational to Navier–Stokes theory. That same year, at age 36, she was shortlisted for the Fields Medal but was passed over for Klaus Roth and René Thom. Oh, you say, but the Fields medal is merit based! Records of the 1958 Fields committee document that its decisions were not solely merit based. Friedrich Hirzebruch, the favorite, was eliminated because he apparently was doing fine and did not need further encouragement, while the committee agreed that Alexander Grothendieck was the most talented after Hirzebruch but figured he could win later. It would take another fifty-six years until the first woman, Maryam Mirzakhani, received a Fields Medal (notably out of the 25 Fields medal signatories only one is a woman). Was this "nurture with great care"? Oh, you say, but things have changed ! Karen Uhlenbeck ( Geometric analysis and nonlinear PDE ): In 2019, Uhlenbeck became the first woman ever awarded the Abel Prize. But after receiving a PhD in 1968 and holding temporary positions at MIT and Berkeley, Uhlenbeck applied for jobs and was told matter of fact that “ people did not hire women ” and that women were supposed to “go home and have babies.” MIT, Stanford, and Princeton were interested in hiring her husband but not her. She was told that “nepotism rules” prevented the universities from hiring her (she examined this years later and the supposed rules could not be found). She eventually obtained a position at the University of Illinois at Urbana–Champaign, which she described as follows: "I hated Champaign-Urbana—I felt out of place mathematically and socially". Was this "nurture with great care"? Oh, you say, but that's just a single example. Cathleen Morawetz ( nonlinear PDE and fluid dynamics ): Morawetz was one of the leading mathematicians in nonlinear PDE and fluid dynamics. That's not quite Navier-Stokes but adjacent. She was the first woman to direct the Courant Institute, president of the AMS, and the first woman mathematician awarded the U.S. National Medal of Science. When she raised the issue of how few women there were in mathematics before an American Mathematical Society governing body, Saunders Mac Lane replied, “Well, mathematics is a very difficult subject.” Was this "nurture with great care"? Of course every mathematician knows that the mathematics community does not nurture with great care all of its students and ideas. This is not a secret and it's not an open secret. It's just common knowledge. In the mathematics department at UC Berkeley, where I worked for 18 years, the department went from barring Julia Robinson ( Hilbert's tenth problem ) from teaching mathematics for 35 years (also using the nepotism rule as an excuse and agreeing to appoint her only after she was elected to the National Academy of Sciences in 1976) to hiring Yuval Pere s (Berkeley math professor ~2001 - 2011). A particularly shocking detail about Robinson is that she was required to document to the personnel office exactly what she worked on every single day (!) In Peres' case eventually mathematicians publicly described at least seven cases or reports involving junior women, some of whom reportedly avoided conferences or lectures to escape his repeated advances. It was not surprising to me that just three years after I arrived at the UC Berkeley math department, the department lost an important NSF grant specifically due to poor student mentorship . And it's outrageous that there is still a prominent faculty member at UC Berkeley (now emeritus) who even today insists there is no, and never has been, sexism in mathematics . One of the defining moments for me in the department was when a graduate student who I knew only in passing, came to my office in tears to tell me "I've just been told I'm stupid" (she is now a very successful professor of mathematics). I'd heard this insult made many times in the department. Once at a faculty meeting a senior professor was asked what he was doing to help one of his graduate students who was in his 9th or 10th year. The reply was "I'm doing nothing. He's stupid". These are not isolated anecdotes. Many mathematicians have experienced rejection not only of their ideas, but of themselves. Perhaps one of the most egregious examples is Yitang Zhang who was told by his advisor " no Chinese student is good ". Was this "nurture with great care"? I found it interesting that the 25 primary signatories on the " A Severe Misalignment of AI in Mathematics " signed the letter with "Fields medalist" in parenthesis. Why not their affiliation, or email address? Did they highlight that they are Fields medal winners to imply that the honor bestows upon them some kind of authority on the mathematics community? Sure- they all did some incredibly important mathematics and were recognized based on extraordinary mathematical ability. But receipt of a Fields Medal also depends on the judgments of a tiny group about which problems, fields, and styles of mathematics deserve recognition. Erdős remarked that “ Szemerédi should have gotten a Fields Medal. [But] the people who decide are not that interested in combinatorics .” Indeed, prizes encode judgments about which mathematics, and therefore which mathematicians, matter. But regardless of Fields medal politics, the point is t
