如果数学家们没有理由去探索自己领域的奥秘,那么我们其他人将不得不踏入一个更加不确定的世界。作者:Konstantin Kakaes在越来越多反对人工智能公司的数学家中,2022年荣获数学领域最高荣誉——菲尔兹奖的雨果·杜米尼尔-科潘(Hugo Duminil-Copin),或许最生动地表达了数学家们的担忧。就在OpenAI上个月宣布解决了被称为“千年大奖问题”的七大数学难题之一之前,他在一篇论文中写道,人工智能的证明“正在摧毁数学领域,每一次冲击都让这片领域变得愈发难以生存”。

If mathematicians have no reason to pursue the mysteries of their field, the rest of us will stumble into a less certain world. By Konstantin Kakaes In the growing chorus of mathematicians revolting against AI companies, Hugo Duminil-Copin, who in 2022 received the Fields Medal, math’s highest honor, has perhaps put mathematicians’ concerns most vividly. In an essay published just before OpenAI announced last month that it had solved one of seven grand mathematical challenges known as the Millennium Prize Problems, he wrote that AI proofs “nuke the mathematical landscape, making it increasingly difficult to inhabit after each blast.”

如果说解决一个千年大奖问题就像投下一颗原子弹,那么OpenAI周二公布的结果就是一场数学领域的地毯式轰炸。数学家们早已对这场冲击有所准备:OpenAI此前曾暗示,其新模型已经找到了“数学大多数领域中超过100个长期悬而未决的问题”的解决方案。而当冲击真正到来时,它带来了由一个尚未命名的专有模型完成的377项新证明。

If resolving a Millennium Prize Problem was like dropping an atomic bomb, then the results that OpenAI shared Tuesday were a mathematical carpet-bombing. Mathematicians had been bracing for the assault: OpenAI had teased that a new model had found solutions to “more than 100 long-standing open problems across most areas of mathematics.”When the drop came, it included 377 new proofs by an as-yet-unnamed proprietary model.

其中大约三分之一是数学界广为人知的猜想的重要证明。另外三分之一在其所属的数学子领域内具有重要意义。剩下的三分之一则要么是次要结果,要么是这些结果的变体。数百人曾花费数十年时间,试图理解并证明OpenAI仅用一天就公布的结果。

About a third are major proofs of conjectures that are famous across mathematics. Another third are significant within their mathematical subfield. The remaining third are either more minor results or variants. Hundreds of people had spent dozens of years trying to understand—and prove—the results that OpenAI released in a single day.

数学家们仍在废墟中仔细搜寻。目前还太早,任何人都无法对OpenAI的研究成果进行详细验证,但多位数学家告诉我,至少部分论文似乎并未真正证明其所声称要证明的内容。(每一次地毯式轰炸中,总会有几枚弹药未能爆炸。)OpenAI已经撤回了三篇论文;不过,该公司的一位发言人在一封电子邮件中告诉我:“我们预计错误会相当罕见。”

Mathematicians are still picking through the rubble. It is too early for anyone to have verified the OpenAI work in detail, but several mathematicians have told me that at least some of the papers appear not to prove what they claim to prove. (Every carpet-bombing has a few munitions that fail to explode.) OpenAI has already withdrawn three of its papers; still, “we expect mistakes to be quite rare,” an OpenAI spokesperson told me in an email.

该公司在最初的声明中还表示,该模型尝试解决了另外约3600个问题,但并未公布这些问题的成功证明。OpenAI承诺将支付费用,请数学家研究由人工智能生成的结果,尽管该公司尚未具体说明资助力度会有多大。

The company also said, as part of the initial announcement, that the model had attempted to solve about 3,600 further problems for which the company did not release successful proofs. OpenAI promised to pay mathematicians to study AI-produced results, although the company has yet to specify how generous the funding will be.

“我们认为数学的未来尚未定论。我们正在与数学界合作,共同探索未来的方向,”这位发言人写道。尽管如此,许多数学家仍对这一未来感到担忧。他们担心,让人工智能直接得出证明,可能会牺牲原本在探索过程中可能获得的成果。他们尤其担心,将如何培养年轻数学家去发现那种灵感的火花,甚至是否还愿意去培养。他们还担心,如果数学家们没有理由继续探索自己领域的奥秘,那么我们其他人最终将陷入一个由机器主宰的世界,而没有人真正理解这些机器的运作方式。

“We don’t believe the future of mathematics is set. We’re working with the math community to navigate the future collaboratively,” the spokesperson wrote. Nonetheless, many mathematicians are looking at that future with apprehension. They worry that having AI leap to solve proofs will sacrifice what the struggle to get there might have yielded. They worry especially about how they will train younger mathematicians to find that spark of life, or wanting to at all. And they worry that, if mathematicians have no reason to pursue the mysteries of their field, then the rest of us will stumble into a world run by machines whose workings nobody understands.

纯粹数学家们花费时间摆弄抽象结构,仅仅是为了探索本身——他们通常并非出于应用需求而为之。然而,一个数学思想可能彻底改变世界的可能性始终存在,并悄然萦绕在背景之中。一位曾为国家安全局从事绝密研究的数学家曾告诉我,真正的分野并非纯粹数学与应用数学之间,而是“已应用的数学与尚未应用的数学”之间。

Pure mathematicians spend their time manipulating abstract structures just for the sake of it—they tend not to be motivated by applications. But the possibility that a mathematical idea will profoundly change the world is always there, lingering in the background. As a mathematician who did top-secret research for the National Security Agency once told me, the real divide is not between pure and applied math, but between “applied math and math that hasn’t been applied yet.”

支撑日常生活的各种技术——每秒发送和接收数十亿位信息的手机、每天将数万亿瓦特能量从发电厂输送到终端用户的电网、流速足以避免堵塞的排污系统、能弯曲25英尺而不折断的飞机机翼、以及通过高频声波合成婴儿心跳的超声成像设备——全都依赖于数学语言。

The technologies that enable daily life—the mobile telephones sending and receiving billions of bits of information every second, the electric grid transmitting trillions of watts of energy from power plants to end users each day, sewage systems that flow fast enough to not clog, airplane wings that flex 25 feet without breaking, ultrasound-imagery machines that synthesize infant heartbeats from high-frequency sound waves—all rely on mathematical language.

这种语言是在数千年的社会互动中锻造而成的。数学家们相互合作,彼此竞争,也会陷入僵局。他们周期性地以更具说服力的新方式重新阐述已知知识。这一切都需要时间,而人工智能通过缩短这一过程,正在危及延续了几个世纪的知识和数学家培养方式,也威胁着人类对这门语言的掌握能力。

That language has been forged through millennia of social interactions. Mathematicians collaborate. They compete. They run into dead ends. They periodically rewrite what is known in new, more compelling ways. All of this takes time, and by short-circuiting this process, AI is imperiling centuries-old practices for creating knowledge and training mathematicians. It is putting human fluency in that language at risk.

人工智能已经削弱了数学探索的一个动机。斯坦福大学数学教授、同时也是旨在评估人工智能数学能力的“第一证明”项目执行主任穆罕默德·阿布扎伊德告诉我:“如果你五年前问数学家他们最重要的工作是什么,答案很可能是‘撰写正确的证明’。但借助人工智能工具,证明的价值已经大幅下降,撰写证明也不再是数学家最重要的活动。”

AI has already undercut one motive for mathematical exploration. “If you had asked mathematicians five years ago what was the most important thing they do, probably it would be that we write proofs and our proofs are correct,” Mohammed Abouzaid, a professor of mathematics at Stanford University and the executive director of First Proof, an effort to benchmark A.I. math abilities, told me. But with AI tools, the value of proofs has already diminished enough that writing them is no longer mathematicians’ most important activity.

证明长期以来一直占据核心地位,因为它们将数学与其他艺术和科学区分开来。证明始于自明之理:例如,如果两个集合的元素完全相同,那么它们就是同一个集合。从这样简单的起点出发,通过大小不一的逻辑步骤,人类构建起了一座庞大而持久的确定性基础架构。

Proofs have long been central because they distinguish math from other arts and sciences. A proof starts from self-evident truths: If two sets have the same elements, for example, then they are the same. From such simple beginnings, proceeding by small and large logical steps, humanity has built an enormous, durable infrastructure of certainty.

作为这座基础架构的基石,证明长期以来一直是专业认可的象征。证明一个重要的结论,你就能获得教职和终身职位;证明一个真正重要的结论,你则会赢得大奖并名垂史册。但如果证明来得过于轻松或过于迅速,反而可能阻碍进步。正如杜米尼尔-科潘(Duminil-Copin)所写,他试图证明概率论中一个著名猜想却屡屡失败,但这些尝试“催生了数十个想法,后来我在其他领域重新利用这些想法,最终实现了自己从未想过能做出的发现”。

As the building blocks of that infrastructure, proofs have long been the currency of professional recognition. Prove something important, and you’ll get a faculty job and tenure; prove something really important, and you’ll get a big prize and a place in history. But if proofs come too easy or too fast, they can choke off progress. As Duminil-Copin wrote, his failed attempts to prove a prominent conjecture in probability theory “generated dozens of ideas that I later repurposed in other contexts, leading to discoveries I would never have imagined making.”

在1994年一篇具有预见性的文章中,20世纪最重要的数学家之一威廉·瑟斯顿(William Thurston)指出,数学界对证明的过度强调适得其反。瑟斯顿本人极其擅长证明,但他也遗憾地指出,像他这样的数学家获得了过多的认可。他表达了自己的惋惜:由于他迅速证明了一系列定理,导致一个名为“叶状结构”(foliations)的领域被放弃,因为没有人愿意与他竞争。

In a prescient 1994 essay, William Thurston, one of the most important mathematicians of the 20th century, argued that the field’s emphasis on proofs backfires. Thurston was himself terrific at proving things and lamented the fact that mathematicians like him got too much credit. He voiced regret that his rapid proof of a number of theorems had led to the abandonment of a subject called “foliations,” because nobody wanted to compete with him.

然而,当人们停止在该领域研究时,他们便忘记了曾经学到的知识。“数学知识与理解力深深植根于特定主题研究者的思维之中,也融入了这个群体的社会结构之中,”瑟斯顿写道,“这些知识虽有书面文献支撑,但书面文献并非真正的核心。”即便你并不了解叶状结构究竟是什么,也足以理解他的观点:数学知识并非永恒不变。

But when people stopped working in the area, they forgot what they had learned. “Mathematical knowledge and understanding were embedded in the minds and in the social fabric of the community of people thinking about a particular topic,” Thurston wrote. “This knowledge was supported by written documents, but the written documents were not really primary.”You don’t need to understand what foliations are to appreciate his point that mathematical knowledge is impermanent.

为了巩固和深化知识与理解,瑟斯顿认为,数学家应当明确自己的目标是促进人类的理解。然而,自他的文章发表以来的30年里,他呼吁赋予除证明之外的事物更高价值的观点,基本上被忽视了。如今,人工智能在提出证明方面或许已经超越任何在世之人,它在整个数学领域做到了瑟斯顿曾为叶状结构所做的一切。因此,数学家们正被迫直面他提出的担忧。

In order to consolidate and build knowledge and understanding, Thurston argued, mathematicians should be clear that their aim is to produce human understanding. But in the 30 years since his essay was published, his call to give greater value to things other than proofs has been largely ignored. AI is now arguably better than any living person at coming up with proofs, doing for all of math what Thurston did to foliations. So mathematicians are being forced to reckon with his concerns.

许多在职数学家对人工智能带来的速度感到兴奋,也热衷于探索利用它来增强自身能力的方式。他们仍然可以继续研究那些对OpenAI新模型而言似乎过于困难的90%的问题;有些人甚至将OpenAI提出的377个证明视为一场地毯式轰炸,而更像是一个装满数学知识新瑰宝的宝箱。

Plenty of working mathematicians are excited at the speed that AI affords them, and the ways they can use it to augment their abilities. They can continue to work on the 90 percent of problems that seem to have proved too hard for OpenAI’s new model, and some see OpenAI’s 377 proofs not as a carpet-bombing but as a treasure chest filled with novel gems of mathematical knowledge.

但这未必能帮助他们未来的继任者。传统上,导师会向一位聪明的研究生布置一个他们估计大约需要几个月时间才能解决的问题。解决这类小而具体的研究问题,能够训练学生应对更深层的问题。人工智能让这种做法显得过时,但正是寻找这些难题的解决方案,才能锻炼出支撑高度抽象数学思维所需的思维“肌肉”。你不可能仅通过阅读现有的数学内容就学会数学,就像你不可能仅通过阅读音乐理论就学会拉小提琴一样。你必须付出相应的脑力劳动和实际练习。

But this won’t necessarily help their successors. Traditionally, an adviser would assign a smart graduate student a problem they estimated might take a few months of work to resolve. Solving such bite-size research questions trained students to tackle deeper questions. AI has turned that practice quaint, but finding those hard solutions is what builds the mental muscles that make exceptionally abstract mathematical thinking possible. You can’t learn math just by reading existing math, in the same way that you can’t learn to play the violin just by reading about music. You have to put in the mental and tactile work.

纪律性极强的学生即使拒绝使用现代人工智能模型,仍然能够学习,但这项技术却让大多数数学学生,即便是非常有天赋的数学学生,陷入了困境。多伦多大学的数学家丹尼尔·利特(Daniel Litt)提出,数学系或许可以设立一些专门的学习空间,让学生每周花20到30小时在没有网络或人工智能的环境中学习,从而有机会掌握所需的技能。无论这种做法是否现实,我们都必须适应一个人类思维价值不断下降的世界,并努力创造一些社会空间,让人类思维依然具有重要意义。

Exceptionally disciplined students can still learn by simply refusing to use modern artificial-intelligence models, but the technology leaves most math students, even very talented math students, in a difficult spot. Daniel Litt, a mathematician at the University of Toronto, has suggested math departments might create rooms where students can spend 20 to 30 hours a week without internet access or AI, to give them a chance at learning the skills they need. Whether or not that’s realistic, we will have to adapt to a world in which the value of human thought is diminished, and try to create social spaces where it still matters.

哈佛大学数学教授、同时也是“第一证明”(First Proof)活动另一位组织者的劳伦·威廉姆斯(Lauren Williams)告诉我,她担心学生会不亲自理解内容,而直接接受计算机给出的答案。她随后在电子邮件中写道,学生们因此感到士气低落:“OpenAI已经生成了一些手稿,声称取得了许多年轻人——比如研究生和博士后研究人员——的研究成果。”如果终身教职的教授被抢了成果,他们仍然有工作保障;但处于职业生涯早期的人可能没有从头再来的时间。

Lauren Williams, a math professor at Harvard University and another of the organizers of First Proof, told me that she worries about students accepting a computer’s answer without engaging with the material themselves. Students are demoralized, she wrote later, in an email: “OpenAI has produced manuscripts claiming results that have scooped the research of many young people, such as graduate students and postdocs.”If tenured faculty get scooped, they’ve still got job security; people earlier in their careers might not have the time to start all over again.

OpenAI发言人指出:“OpenAI的许多人认为,该领域的资深成员有责任迅速推动这一领域的发展,以适应人工智能带来的新现实。”换言之,该公司认为数学家必须接受其对该领域未来的构想,否则就该退到一边。但该公司在某种程度上也回应了数学家们的批评。上个月,它召集了一个由八位成就卓著的数学家和埃德·威滕(Ed Witten)——或许是全球最具影响力的物理学家——组成的独立顾问小组。

The OpenAI spokesperson noted that “many at OpenAI believe that the senior members of the community have a responsibility to rapidly evolve the field to adapt to the new reality that AI brings.”In other words, the company believes that mathematicians need to get on board with its vision of the field’s future or get out of the way. But the company has also responded, in some ways, to mathematicians’ critiques. Last month, it convened an independent advisory group of eight extremely accomplished mathematicians and Ed Witten, arguably the world's most influential physicist.

9月29日,该顾问小组发布了第一份报告:要求前沿人工智能实验室停止在“专有模型上测试高级数学问题,而这些模型仍无法被更广泛的科学界访问”。整整一周后,OpenAI无视了这一指示,并发布了其通过此类专有模型获得的证明。该公司也采纳了顾问小组的部分建议:随附证明的论文被上传至GitHub,而非由OpenAI自行在线托管,以留下可供审计的书面记录;此外,10项证明还附带了人工智能得出这些结论的过程说明。

On September 29, the advisory group issued its first report: It asked frontier-AI labs to stop testing “advanced mathematical problems on proprietary models that remain inaccessible to the broader scientific community.”Exactly one week later, OpenAI snubbed this instruction and released its proofs, obtained by just such a proprietary model. The company followed some of the advisory group's recommendations: The papers accompanying the proofs were uploaded to Github rather than hosted online by OpenAI itself, to leave an auditable paper trail, and 10 of the proofs were accompanied by an explanation of how the AI arrived at its conclusions.

OpenAI 的论文明显比早期由人工智能撰写的证明更清晰,但总体而言,这些论文写得并不好。(据该公司称,在发布的 722 篇手稿中,只有一篇经过人类编辑。)威廉姆斯写道:“符号和语言不自然,推理也不清晰;这些手稿并不像是自尊自爱的数学家会公之于世的作品。通常,当我们证明一个结果时,我们会花费数周,甚至数月或数年时间,努力找出最清晰、最简洁的解释来说明所有部分如何契合,从而真正推动人类的理解。但这里并没有发生这种情况。”

The OpenAI papers are markedly clearer than earlier generations of AI-written proofs, but on the whole, they are not well written. (Only one of the 722 manuscripts released has been edited by a human, according to the company.) “The notation and language is unnatural, the reasoning is unclear; they are not the sorts of manuscripts that a self-respecting mathematician would release into the world,” Williams wrote. “Normally when we prove a result, we spend weeks if not months or years working hard to come up with the clearest and cleanest explanation of how all the pieces fit together, so as to genuinely contribute to human understanding. That is not what has happened here.”

OpenAI 的发言人表示,该公司正在“努力提升未来模型的写作能力”。数学是一项高度依赖社交协作的活动。数学家们会在夏季研讨会上齐聚数周。他们跨越国界和时区,非正式地、合作性地工作,常常持续到深夜。其成果是一种共享的人类理解,这不仅支撑着一个充满严谨抽象概念的奇妙世界,也支撑着让 80 亿人能够在地球上生活的各种技术。

The OpenAI spokesperson said that the company is “working to improve future models’ writing ability.”Math is a deeply social undertaking. Mathematicians gather for weeks at summer workshops. They work informally, collaboratively, and late into the night, across borders and time zones. The result has been a shared human understanding, which underpins not only a numinous world of rigorous abstractions but also the technologies that make it possible for 8 billion people to live on Earth.

目前,数学家们仍然能够解释数学为何以及如何以这种方式运作。如果他们无法找到方法将这些知识传承下去,影响的将不仅是数学家,还包括所有依赖他们智慧成果的我们。

Right now, mathematicians can still explain how and why math works as it does. If they cannot figure out how to pass that knowledge on, it will affect not only mathematicians, but all of us who rely on the fruits of their intellect.
