Cédric Villani on AI, Politics, and Europe's Missed Chances: A Conversation with Takahiro Anno in Paris

Open on YouTube ↗
Overview

Takahiro Anno is an engineer and founder of the Japanese political party Team Mirai. In Paris he met Cédric Villani, a Fields Medal–winning mathematician who served in the French National Assembly and in 2018 wrote the report that shaped France's national AI strategy. Anno came with two kinds of questions. The first was practical: how a very young party should handle its growth in parliament. The second was about AI, both as a tool for making policy and as a force that is reshaping science, the economy, and geopolitics.

Villani's positions run through the whole conversation. He thinks AI in politics has so far mostly served populists, surveillance states, and militaries. He believes the concentration of AI power in a few American companies is the most urgent problem. And he sees Europe's answer in its own strength, built on open models and coordinated public investment. He was also frank about the problems he does not know how to solve.

A personal opening: Japan, anime, and Birth of a Theorem

Villani began by describing his ties to Japan. He estimates he has made about ten trips there, visiting Tokyo and Kyoto as well as Hokkaido, Shikoku, and the "artist islands" around Teshima. He said he had seen most of the classic Japanese films and read most of the manga classics, and that his children grew up on Tezuka. Most French people know Miyazaki, he noted, but he was an "enormous fan" of Satoshi Kon, the director of Perfect Blue, and had seen all his films. Paprika was his favorite, partly because it appeals to someone interested in AI. He called Kon's early death a tragic loss.

He also mentioned that his book Birth of a Theorem had been translated into Japanese. He regretted not bringing a copy and promised to send one. In his view the Japanese edition is one of the most beautiful of all the international editions. It includes an afterword by an older Japanese mathematician who was his friend and who died soon after writing it, which Villani said makes it a very personal edition.

Comparing parliamentary trajectories: from a 300-member majority to sitting alone

Turning to politics, Villani asked about Anno's party. Anno said it was one year old, had been through two national elections, and that he sits alone in the upper house without joining a coalition. In January the party won 11 seats in the lower house. The figure shifted between 10 and 12 at different points in the conversation, but 11 was the number Anno confirmed. That is enough to form an independent parliamentary group. Anno described this as a historical record in Japanese politics for a one-year-old party, especially since the party was built from scratch rather than splitting off from an existing one. He said this cuts both ways. There is no organizational base, but the party has "free hands" to decide things for itself.

Villani said he knows what sitting alone feels like. Within a single term he went through three situations. For about two and a half years he sat in the majority group, which had "300 something" members. For roughly six months he belonged to a much smaller dissident group of about 17 people. When that group lost members and fell below 15, the minimum in the French assembly, it dissolved. About ten of its members, Villani among them, chose to sit on their own for the last two years of the mandate. So, he said, he had experienced a very big group, a very small group, and no group at all. Anno replied that he has never been in a big group, but has gone from being alone in the upper house to effectively leading a group of eleven.

The hardest problem for a new party: having a position on everything

Villani's main advice came from what he had seen of new movements entering parliament. A movement or NGO can focus on one subject. A party, he argued, is expected to have an opinion on every subject, including foreign relations, immigration, and the death penalty. Once a movement reaches parliament, this is often where it discovers internal rifts.

He offered Macron's party as an extreme case. He recalled that it had about 300 deputies, many with no prior political experience. All of them had been carried along by Macron's brilliant campaign and believed the program would be what they had dreamed of. In practice, Villani said, the group held very different visions, from very progressive to very conservative. There was no real philosophical consensus about what the party was, and it became "a big mess." In his view, even today the president's party is the only major French party without a clear political vision. With the other parties, people know what they like and what they don't.

The Japanese side said Team Mirai faces exactly this tension. They describe the party as "multi-issue" but not a "full package." It works on children, labor, and education, which are things focused on the future, but takes no positions on foreign relations, constitutional questions, or immigration. On issues outside its core, members are free to vote as they choose. Much of the criticism the party receives, they said, is precisely that it is not a full package.

Villani said a freedom of vote on particular sensitive issues is "completely okay" and that he has seen other parties do it. But he said it should be restricted to a well-identified core. He added a caveat: if people ever expect the party to join a governing coalition, it will need positions on everything, because it will have to decide whether to support the government on every issue.

He described his own experience. When he entered parliament he was confident on science and fairly solid on international affairs, because he had worked with European think tanks and calls himself a European federalist. On many other subjects he found himself wondering what he should even think. At first, he said, one can tell the media "we are not yet prepared," but after a while the media are no longer satisfied with that.

15:04

"I don't know" versus the media's demand for certainty

Anno said that, in his personal view, a politician should say "I don't know" when they genuinely don't know. Villani agreed in theory and said he occasionally did it early on. But he argued that in today's world of media and image, saying "I don't know" too often "just doesn't work." He found it paradoxical that people who are firmly convinced of something and change their opinion many times cause less trouble than people who have no opinion.

His extreme example was Donald Trump. Villani described him as changing positions every month, always claiming he had held his current view all along, and presenting himself as the world's greatest expert on taxes, war, economics, and, Villani joked, probably mathematics too. Somehow, Villani observed, this looks more reassuring to many people.

His practical advice was to work seriously on the issues inside the party. That means inviting experts with different points of view and taking the time to build a complete program. The party may lose a few people who decide "this was not my project," but Villani's guess is that clarity will attract more supporters and make the party more stable.

17:11

Team Mirai's approach: an in-house engineering team and open-source policymaking

Anno then explained what he sees as a distinctive feature of his party. It has an in-house software engineering team that builds platforms to gather opinions from the general public, process them, and turn them into policy proposals. He said the party is interested in AI in two ways: as a tool politicians can use to make better policy, and as a force that will radically change society. He asked Villani in particular about AI's effect on science, mentioning the news that week about Navier–Stokes.

18:06

Villani's warning: AI in politics has so far served populists, control, and war

Before addressing science, Villani said he wanted to make "another comment beforehand." He argued that politicians have been interested in using AI for politics for a long time, but mainly on the populist right. He said the first to do this systematically were Italy's Five Star Movement. He recommended a book by an Italian political scientist named Giuliano, published in French as Les Ingénieurs du chaos (The Engineers of Chaos), which he thought was written around five years ago. According to Villani, the book traces how this kind of AI-driven politics was first tried by Five Star, then taken up by Orbán in Hungary, by Polish politicians, and by Trump and his teams.

Villani summarized the logic as he understood it from the book. At some point the Five Star strategists stopped asking what they wanted to say and started asking what people wanted to hear so that they would get elected. AI would tell them, and they would adapt. In Hungary, he said, they became experts at this: each morning the AI says what to say, and the politician says it. He called it "computerized politics."

Villani said he knows of no example of a progressive party that has used AI successfully. He named two other areas where AI has succeeded. One is controlling citizens, as in China. The other is war. He mentioned a film released that morning about how the Israeli army used AI to target the homes and families of people it wanted to kill in Gaza. He said the film features people from the army speaking, and that it shows up to 500 civilians being killed to hit a single target. His conclusion: AI in politics has so far been very successful for populist parties, for controlling populations, and for waging war. "We are still waiting about the very successful AI to do the good of people."

21:33

Anno's response: transparency and reviewability as the difference

Anno called this a good point. He answered that his party wants the process to be transparent and reviewable. It open-sources its software and publishes the prompts and models it uses, so that anyone can, technically, propose changes or submit a pull request. The party does not want to become authoritarian through its use of AI. Anno's hypothesis is that AI can be used in a more democratic way and can strengthen democracy. He stressed that nobody yet knows the right method, so many trials are needed.

Villani recalled that a few years ago France also had a burst of activity among small startups looking for new democratic tools, such as new ways to poll, to make suggestions, or to evaluate politicians. That "agitation," he said, has largely died down, and the focus is now on enormous AI projects. Asked why, he pointed to funding. Money shifted from being spread widely to being concentrated on very big players. Competition became intense, and a process of enormous selection left only the biggest survivors.

24:10

From science to politics to economics: the scale of the AI race

Villani gave a deliberately caricatured history of AI. Ten years ago the field was dominated by science, five years ago by politics, and now by economics: "who gets the billions." He added that AI now reaches both the "true economy," such as energy, and what he called the "magic economy" of finance.

He gave some numbers to show the scale. According to him, each of the super-large American AI companies is spending about half a billion dollars per day on AI. He compared this to the cost of a real war, saying the war in Ukraine runs at about half a billion to a billion per day, and called these levels unprecedented. He also said that last year, for the first time, Google announced it was losing some of its cash. Before that, he said, it had more money than it knew how to spend, and now it is running short because of what the race requires.

25:29

Science and the "two problems"

On science itself, Villani made one concrete prediction. The International Congress of Mathematicians meets every four years, and he said it is quite possible that 2026 was the last congress "of a classical type," with all future ones deeply shaped by AI. That is the first problem: the work of scientists is being completely changed.

He considers the second problem more urgent. The key actors are a handful of "super huge crazy capitalist companies" worth hundreds of billions and, in his words, under the control of a president who is "a madman." Even if everything else changes, he said, we should at least keep some control. He believes this can only happen if many forces come together around open source and transparency to build very powerful shared packages.

He cited Yann LeCun, whom he called a French superstar. Villani noted that LeCun left Meta and started a French company. He said LeCun has consistently argued that the best LLMs will eventually be the open ones, because they will not be distorted by censorship, reputational fears, and similar pressures, and will be controlled by a community, much as Wikipedia is by and large the best encyclopedia available. Villani said this may be true. But the private forces now in play are so strong that it is hard to see how an open sector could raise comparable investment.

He then gave a small personal observation. According to him, last year Wikipedia saw its request rate fall for the first time in its history. On his Android phone, he said, the device now pushes him toward Gemini's answer before Wikipedia's, whereas a year or two ago the Wikipedia result would have come first.

28:40

If he were president: a European answer

The Japanese side asked what Villani would do if he were president, in any field: science, education, or the labor market. He began by saying he disagrees with Macron on many things, but on this issue he thinks Macron's overall vision and policy went in the right direction.

He stressed that the answer depends heavily on a country's geopolitical and economic situation, and said his answer is a European one. The priority, as he sees it, is to strengthen the European Union in AI. That means building on its human resources, skills, and scientific networks so the whole region becomes bigger and stronger in economics, talent, public relations, and training. It is an "ecosystem" effort that also reinforces the open sector.

Within the EU he named France as strong in AI and called Poland "the other giant." He said young Polish programmers are among the best in the world and the Polish digital economy is growing very fast, which makes Poland an important ally. He extended this to the broader Slavic culture of Eastern Europe. He also said Europe lost the UK, which he described as probably better than France in AI overall, but whose ties to the United States "destroy the whole thing."

31:08

The single biggest regret: Brexit and DeepMind

Villani said his "single biggest regret" in this whole area is the combination of Brexit and Google's acquisition of DeepMind. If the UK had stayed in Europe, and if Europe had funded DeepMind at the level it deserved, then DeepMind might be European. In his view it is the actor that, until very recently, had the strongest record in science. He asked the listener to imagine how different the geopolitics would be. Instead, he said, Demis Hassabis now stands next to Donald Trump at the G7. "What a pity," he said. The solution, he argued, has to start from politics and from Europe's own internal forces.

32:14

The 2018 report: what it achieved

Anno asked whether Villani's 2018 report had shaped AI policy. Villani said it had an impact. He cited independent evaluations by French oversight bodies, which he said concluded that the strategy kept France in the race, roughly in the top ten AI countries, and that without it France would clearly have fallen behind. It was still not enough, he said, to put France in the same league as the US, Canada, China, the UK, and perhaps Israel. But France remained a major player. He pointed to VivaTech, now a large international AI event in Paris, and to French companies including Mistral. He said these companies are a hundred times smaller than the giants but still in the billion-dollar league, and that they are so far the only decent LLM alternative that is neither American nor Chinese, apart from perhaps the Polish founders of ElevenLabs.

He attributed part of the report's success to its fit with Macron's identity. Macron wanted to present himself as a president engaged with the future and friendly to tech and international business. During the report process, Villani co-organized an international workshop with one of Macron's advisers, and Macron had dinner directly with figures including Yann LeCun and Demis Hassabis, with the whole discussion in English, which Villani called rare in the French system. Cathy O'Neil, author of Weapons of Math Destruction, whom he described as highly respected on AI ethics, was there. So were Meredith Whittaker, now president of Signal, and Kate Crawford. Villani contrasted this with Trump's dinners with big-tech CEOs, which he characterized as an "I'm the boss" display. Macron, by his account, was trying to understand: "tell me what I should know."

Villani estimated that about half of the report was put into action. He called that a very high figure, since he said parliamentary reports usually see 10% implementation, or even 0%. The public debate around the report also made him a recognized voice on AI. He said that even now he is invited to an AI debate roughly every week, largely because of it.

36:23

What worked, what didn't, and what he can't solve

According to Villani, the research system and the medical and health measures saw good progress, and a number of the main measures were carried out well. The areas least addressed, where he said the government did not really know what to do, were gender and training. Women remain heavily underrepresented in AI. And not enough people are being trained.

On training he added a caveat that he said he does not know how to handle. For the first time, programming students are having difficulty getting hired. Society still needs programmers and people who understand the whole technology, but large companies are using fewer and fewer of them. In his view this is starting to cause serious security problems, because many people are needed to check, maintain, and fix systems. The Japanese side said this was exactly the topic they most wanted to discuss. Villani repeated that it is a real, big issue and that he does not know how to handle it.

37:37

Regulation, fragmentation, and the missing European project

On regulation, Villani said he likes what Europe did with the AI Act and considers it good regulation. Implementation, however, remains a problem. He said the regulation is applied in many different national "shades," and that Mistral, for example, is being driven crazy by having to follow one interpretation in the Czech Republic, another in France, and so on. He said it needs simplification.

His biggest concern is the lack of concentrated action and strong networks. Europe could have a large open LLM project, he argued, but it would need to be a public-private partnership. In his view, fully public projects run into many difficulties, and public-private partnerships are not easy either. Public budgets are not big enough to drive such a project alone, so public money should at least serve as an incentive. He called this the most important task, and said it would require coordinated European action. That is where the conversation ended: the European open-model project he describes does not yet exist, and he still has no answer for the collapse in programmer hiring.
