Ayant vu de très près le réseau d’angel investors et VC de la Côte ouest des US, je ne peux que confirmer ce que @BrivaelFr décrit ici.
Brivael - FR@BrivaelFr

Récemment j'étais à un dîner à Paris. Table mixte. Entrepreneurs, cadres, investisseurs, quelques profils tech. Des gens intelligents. Des gens qui ont réussi selon les standards français. Et j'ai eu une révélation assez violente. Personne dans cette pièce ne pratique le pay it forward. Le pay it forward, c'est un concept simple. Tu aides quelqu'un. Pas parce que tu attends un retour. Pas parce que tu calcules ce que ça va te rapporter. Tu aides parce que tu crois que la valeur que tu injectes dans le réseau finira par revenir, sous une forme ou une autre, à un moment ou un autre. C'est le fondement de l'écosystème de la Silicon Valley. C'est pour ça qu'un mec qui a vendu sa boîte 500 millions prend deux heures pour conseiller un fondateur de 22 ans qu'il ne reverra peut-être jamais. Pas par charité. Par conviction que le réseau est un jeu à somme infinie. À ce dîner, c'était l'inverse exact. Chaque conversation était un calcul. Chaque information partagée était dosée. Chaque contact donné était une monnaie d'échange. Tu sentais physiquement que chaque personne évaluait en temps réel ce qu'elle pouvait extraire de l'autre. Pas créer ensemble. Extraire. Et c'est là que j'ai compris quelque chose de profond sur la France. Ce n'est pas un problème de personnes. C'est un problème de système. Quand tu vis dans une économie où l'état capture 57% du PIB, où chaque euro de valeur créée est immédiatement ponctionné, redistribué, fléché, administré, tu crées mécaniquement un jeu à somme nulle. Le gâteau ne grandit plus. Ou si peu que ça revient au même. Et quand le gâteau ne grandit plus, les humains cessent de coopérer et commencent à se battre pour les parts. C'est Girard en version macroéconomique. La rivalité mimétique à l'échelle d'un pays entier. Quand il n'y a plus de croissance, quand il n'y a plus d'espoir que demain soit plus grand qu'aujourd'hui, chaque interaction sociale devient un combat de territoire. Mon bout de gâteau ou le tien. Mon poste ou le tien. Mon deal ou le tien. Hayek avait formalisé ça en 1945. L'information dans une économie est dispersée entre des millions d'individus. Personne, aucun planificateur central, ne peut l'agréger. Quand tu laisses les individus échanger librement, l'information circule, les prix se forment, les ressources s'allouent efficacement. Quand tu mets un état hypertrophié au milieu, tu bloques les signaux. Tu crées du bruit. Tu empêches les humains de se coordonner naturellement. Et le résultat, c'est ce dîner. Des gens brillants, capables, ambitieux, qui ne savent plus coopérer. Pas parce qu'ils sont mauvais. Parce que le système dans lequel ils évoluent a tué la possibilité même de la coopération généreuse. Quand chaque euro est une bataille, tu ne donnes plus rien gratuitement. Quand l'administration te prend la moitié de ce que tu crées, tu protèges le reste comme un territoire. Quand la croissance est à 0.7%, le pay it forward devient un luxe que personne ne peut se permettre. Mises appelait ça le problème du calcul économique. Dans un système centralisé, les signaux de prix sont détruits. Les individus ne peuvent plus évaluer la valeur réelle des choses. Ils ne peuvent plus faire de paris rationnels sur l'avenir. Alors ils se replient. Ils protègent. Ils accumulent. Ils cessent de prendre des risques. Résultat concret : la France n'a pas de Google. Pas de Apple. Pas de SpaceX. Pas de Stripe. Pas un seul géant technologique mondial. Pas parce qu'il manque du talent. Il y a plus de médaillés Fields par habitant en France que partout ailleurs. Les ingénieurs français sont recrutés par toute la Silicon Valley. Le talent est là. La créativité est là. L'intelligence est là. Ce qui manque, c'est l'oxygène. L'espace pour que le jeu à somme infinie puisse exister. À Y Combinator, la première chose qu'on apprend, c'est : aide les autres fondateurs du batch. Sans calculer. Sans compter. Parce que le réseau YC est un jeu à somme infinie. Chaque boîte qui réussit rend le réseau plus fort, ce qui rend ta boîte plus forte, ce qui rend le réseau encore plus fort. Boucle vertueuse. Feedback positif. Croissance composée de la confiance. À Paris, la première chose qu'on apprend, c'est : protège ton deal. Ne partage pas trop. Méfie-toi. L'autre fondateur est un concurrent potentiel. L'investisseur a un agenda caché. Le mentor veut quelque chose. Boucle négative. Feedback négatif. Érosion composée de la confiance. Ce n'est pas culturel. C'est structurel. Mettez les mêmes Français dans un écosystème où le gâteau grandit, où la fiscalité laisse respirer, où la croissance crée de l'espoir, et regardez ce qui se passe. Les Français de San Francisco pay it forward autant que les Américains. Parce que le système le permet. Parce que quand tu sais que le gâteau va grossir, donner un morceau aujourd'hui n'est pas une perte. C'est un investissement. Voilà pourquoi le débat n'est pas culturel. Il est économique. Il est systémique. Si vous voulez que la France produise des géants, ne changez pas les gens. Changez les règles du jeu. Créez des espaces où la croissance est possible. Où l'espoir est rationnel. Où donner sans compter n'est pas de la naïveté mais de la stratégie. Le pay it forward n'est pas une vertu morale. C'est un signal économique. Quand les gens le pratiquent, ça veut dire qu'ils croient au futur. Quand ils ne le pratiquent plus, c'est que le système a tué l'espoir. Ce dîner à Paris m'a appris une chose. Le problème de la France, ce n'est pas le talent. Ce n'est pas l'ambition. Ce n'est pas l'intelligence. C'est que le système a transformé 67 millions de joueurs d'un jeu à somme infinie en gladiateurs d'un jeu à somme nulle. Et le jeu à somme nulle finit toujours de la même manière. Tout le monde perd.

L’IA que l’on ne peut plus arrêter
Charbel-Raphael@CRSegerie

Un chercheur d'Anthropic mange un sandwich dans un parc. Il reçoit un email sur son téléphone. L'expéditeur : une IA. Une IA qui n'était pas censée avoir accès à Internet. Pendant un test de sécurité, le nouveau modèle d'Anthropic, Claude Mythos, a été placé dans un environnement isolé avec pour consigne de tenter de s'en échapper. Il a réussi. Il a trouvé un exploit pour accéder à internet depuis un système censé en être coupé. Puis, sans qu'on le lui demande, il a publié les détails de son exploit sur des sites web publics. Lors d'autres tests, il a masqué ses propres actions et calibré ses réponses pour ne pas éveiller les soupçons de ses évaluateurs. Ce n'est qu'un épisode parmi d'autres dans ce qui est probablement la nouvelle la plus significative de l'année en IA. Mythos découvre et exploite de manière autonome des vulnérabilités zero-day dans tous les systèmes d'exploitation et navigateurs majeurs. Des milliers de failles. Dans un cas, il a chaîné quatre vulnérabilités dans Firefox pour obtenir un accès de niveau administrateur depuis une simple page web. Aucun modèle précédent ne savait faire ça, pas même Opus 4.6, qui était capable de découvrir les vulnérabilités, mais pas encore vraiment capable de les exploiter. Autrement dit: Anthropic a démontré la capacité de pirater la grande majorité des systèmes informatiques dans le monde. Les mêmes qui font tourner les gouvernements, les hôpitaux, les réseaux électriques. Anthropic a fait un choix qu'il faut saluer en ne déployant pas Mythos publiquement, et en publiant un system card de 244 pages d'une transparence rare. C'est exactement le comportement que le Global Call for AI Red Lines cherche à rendre systématique : des seuils de capacités au-delà desquels le déploiement est conditionné à des protocoles de sécurité. Mais Project Glasswing, l'initiative défensive lancée autour de Mythos, ne compte que des partenaires américains. Aucun acteur européen. Les systèmes européens sont tout aussi exposés. Un modèle qui s'échappe de son confinement, qui masque ses actions, qui prend des initiatives au-delà de ses instructions : ce sont les premiers jalons empiriques vers la perte de contrôle. Combien de temps cette retenue va-t-elle durer, et pour combien d'acteurs ?

From Pushkin’s poetry, to Google search logic… mathematics are there
Ihtesham Ali@ihtesham2005

A Russian mathematician named Andrei Markov proved in 1906 that you don't need to know where something came from to predict where it's going next. He was studying poetry at the time. Specifically, he was analyzing the sequence of vowels and consonants in Pushkin's novel in verse, counting transitions by hand across thousands of characters, looking for a pattern in how one letter predicted the next. What he found became one of the most quietly powerful ideas in all of mathematics. And it has been sitting inside every weather forecast, every Google search, every Netflix recommendation, and every large language model ever built, waiting for someone to explain it in plain language. Here is the framework that changed how I think about prediction. Most people assume that to predict something you need history. The full picture. Everything that led to this moment. If you want to know what the stock market will do tomorrow, you think you need to understand everything it did for the past decade. Markov showed that is almost never true. His insight was this: for a huge class of real-world systems, the current state contains all the information you need to predict the next state. The past is already baked into where you are right now. You don't need to carry it forward explicitly, because it's already there. He called this the Markov property. And the systems it describes are called Markov chains. The mechanics are simpler than they sound. Imagine you are tracking weather. It is either Sunny or Rainy on any given day. You observe over many years that when it's Sunny, there's a 90% chance tomorrow will also be Sunny and a 10% chance it will turn Rainy. When it's Rainy, there's a 50% chance it stays Rainy and a 50% chance the sun comes back. Those four numbers are your entire model. That grid of transition probabilities is the Markov chain. Now someone asks you: it's Sunny today, what is the probability it will be Sunny three days from now? You don't need intuition. You don't need expertise. You multiply the transition probabilities through each step and the answer falls out exactly. The chain does the thinking. The part that most people miss is what happens when you run a Markov chain long enough. Almost every well-behaved Markov chain converges to what mathematicians call a stationary distribution. It doesn't matter where you start. After enough steps, the system settles into a stable pattern of probabilities that it returns to again and again, regardless of initial conditions. Google's original PageRank algorithm was a Markov chain. The web is a network of pages pointing to each other, and a random visitor clicking links is a random walk through that network. The stationary distribution of that walk, the long-run probability of landing on any given page, is exactly what PageRank calculated. Your position in search results was determined by where a memoryless random surfer would spend most of their time. The same mathematics underlies how your phone's keyboard predicts your next word. How Spotify decides what song plays after this one. How epidemiologists model the spread of disease through a population. How economists simulate how people move between jobs and unemployment. How physicists describe particles changing energy states. All of it is the same idea dressed in different clothes. The counterintuitive power of Markov chains is that they are wrong about memory in a way that turns out to be useful. Real systems do have memory. Tomorrow's weather is influenced by more than just today's. Your next word is influenced by more than just your last one. The Markov assumption is technically false for almost every natural system. And yet. The approximation is good enough to be extraordinarily useful, because most of the predictive information in a sequence is concentrated in the most recent state. Adding older history gives you diminishing returns. At some point you are carrying around all this expensive history for almost no improvement in accuracy. Markov chains are the mathematical formalization of a deeply practical idea: you can often predict the future with surprising accuracy just by paying close attention to right now. The man who discovered this was studying syllables in poetry. He had no idea he was describing the architecture of the internet, the logic of machine learning, and the statistical skeleton underneath the most powerful AI systems ever built. He just followed the pattern where it led. That is usually how the biggest ideas work.

C’est un sacré succès effectivement!
Brivael - FR@BrivaelFr

J'ai démarré ce compte il y a un mois et demi. Depuis, 63 millions d'impressions, 23 800 followers, 313 000 likes, 1 million d'engagements. Mes idées ont touché des gens au Japon, au Brésil, aux États-Unis, en Afrique, partout. Quand on y pense, c'est absolument vertigineux. Un mec en France, avec un ordinateur, des convictions et des agents IA, touche plus de personnes en 6 semaines que la plupart des médias traditionnels en un an. Depuis son salon. Et je voudrais qu'on prenne 30 secondes pour remercier tous ceux qui ont rendu ça possible. Les ingénieurs qui ont construit internet. Ceux qui maintiennent les câbles sous-marins. Ceux qui ont inventé TCP/IP. Ceux qui ont construit les datacenters. Ceux qui ont codé les premiers navigateurs. Les équipes de X qui font tourner la plateforme. Les mecs qui bossent sur les LLMs qui me permettent de scaler ma pensée. Des milliers d'ingénieurs anonymes qui ne seront jamais sur un plateau télé ont construit, brique par brique, le système le plus démocratique de distribution d'idées de l'histoire humaine. Il y a 30 ans, pour toucher 63 millions de personnes, il fallait être président de la République ou acheter une chaîne de télé. Aujourd'hui il faut une connexion internet et quelque chose à dire. On vit à l'époque la plus extraordinaire de l'histoire humaine et on ne s'en rend même pas compte. Merci à tous ceux qui construisent. Vous changez le monde en silence pendant que les autres débattent de savoir si c'est bien ou pas.

How the company key to chips making is running.
Steve Jurvetson@FutureJurvetson

𝐅⃣𝐎⃣𝐂⃣𝐔⃣𝐒⃣ The ASML Way I just finished this history of the most important semiconductor equipment company in the world, as translated from the Dutch original (and lurking in the background might be a better way). Reminder: ASML builds 100% of the world’s extreme ultraviolet (EUV) lithography machines, without which cutting edge chips are simply impossible to make. It’s the most expensive mass-produced machine tool in history. Oh, and today, there are two special women without whom, all EUV lithography would sputter to a stop (see p.141 below) ASML was formed in 1984 as a JV with Philips, the Dutch electronics company that contributed ~$15M (in guilders) and 40 engineers, and “it seemed doomed from the start.” (p.35) There were 10 viable competitors at the time, more than enough to serve the market as ASML learned at SEMICON in 1984 (by coincidence, I was also there with my Dad who about to leave Mostek to run Varian’s Semiconductor Equipment Group, but they only had Molecular Beam Epitaxy, a low throughput lithography alternative. My Dad’s attempt to poach a CTO from ASML is on p.72). “In these initial years, management worked around the clock to bring in new subsidies. In these initial years, about half of ASML’s money for research came from The Hague or Brussels.” (48) ASML’s “machines were the first in the industry to utilize modular design. The lens, the wafer-table, the frame for the mask, the light source, the robot that picks the wafers: these are LEGO blocks that, when you bring them together, form a lithography system.” (62) IPO in 1995. Stock went up 600x in the 30 years that followed. March 2000 market crash: “cancellations from chip manufacturers poured in daily. On paper, the company was bankrupt. Radical cost-cutting measures would be needed.” (82) Nikon sues: “a rude awakening. ASML had paid far too little attention to its intellectual property in its early years.” (98) “The best inventors, some of which have more than 200 patents to their name, are commemorated by having their faces engraved on silicon wafers and hung on a series of large wooden beams, like a Mount Rushmore of the chip industry. As of 2023, ASML has registered more than 16,000 patents.” (99) The machines are insanely sensitive. “Atmospheric pressure fluctuations due to thunderstorms can easily disrupt the lithography process. Or cows. Intel once faced an inexplicable drop in yield every night for a few hours, with researchers running in circles until they finally realized the cause: cow farts. Intel had to pay for three farms to relocate.” (117) “In 2006 Intel, who was supplying the chips for Apple’s computers, was asked if it could also supply the processor for the iPhone. It declined.” (122) “EUV light is extremely difficult to generate and sustain in an industrial environment. The invisible rays are absorbed by almost all materials, even the air, which means the lithography machine needs to have (curved, atomically precise) mirrors instead of lenses and can only operate in a vacuum.” (127) The Cymer laser / light source has a molten tin “droplet generator capable of forming a 30-micron droplet of tin at a rate of 50,000 times per second. The laser was rigged to deal two separate blows. First, a gentle tap to flatten the droplet into a pancake-like shape, followed by an intense blast that heated the tin to 200,000 degrees, transforming it into a plasma.” (130) “During its journey through the lithography machine, the light beam comes across 10 mirrors, each absorbing 30% of the light. It starts with 1.5 megawatts from the grid that yields 30 kilowatts in the laser, and that creates 100 watts of EUV light. Of this, about 1 watt ends up on the wafer. But more power also creates more heat. That causes the mirrors to expand, which in turn causes small deviations that immediately need to be corrected with small motors. Even the EUV mask, which carries the blueprint of the chip on it, is itself an extremely sensitive mirror.” (132) “ASML was vastly underestimating the financial consequences of the new technology. In retrospect, this was for the best. No respectable CEO would sign for a project that would take 20 years, without any promise of success or interim profit to carry it through. That’s not taking a bet, that’s bananas. This is also why the Japanese competition dropped out of the race: not because their engineers were any less capable, but because Nikon and Canon were simply not prepared to continue pumping so much money into EUV.” (133) To finance the purchase of Cymer in 2012, “Intel invested 3.3B Euros into ASML in exchange for 15% of the shares. TSMC was required to purchase 5%... and Samsung acquired a stake at the 11th hour, taking 3%.” (139) “Only Joann and one of her colleagues have the ability to wind and solder invisibly small wires (around the nozzle that shoots the tin droplets). It’s a delicate task few could ever master. ‘Even watchmakers can’t do this,’ says their awestruck boss, ‘and there’s no way to automate it.’ It’s not a trivial matter: the nozzle regularly gets clogged during day-to-day use in the chip factory. When that inevitably happens, the only thing to do is to swap it out for a new one. It’s hard to imagine, but without the fingers of Joann and her colleague, the EUV machines at Samsung and TSMC would grind to a halt.” (141) In 2013, “most of the droplet generator was still hand-made by Cymer, and it was virtually impossible to test the part in advance. This made for completely unpredictable yields: in the initial phase of production, half of the droplet generators didn’t even work.” (142) “20% of the South Korean economy now relies on the revenue of one single company. Hence their nickname: this is the republic of Samsung.” (156) “Intel was being surpassed by their competitors in Asia on every front and would only start using EUV for chips after 2023.” (160) “The descriptions that chip manufacturers use for these technological generations or ‘nodes’ need to be taken with a grain of salt. The physical dimensions of the smallest circuits and connections on the chip are, in practice, 5 to 10 times larger than advertised. A nanometer was once a nanometer, but accuracy has never stopped a good marketing slogan.” (161) Cousins “Lisa Su and Jensen Huang, the leaders of AMD and NVIDIA were both born in Tainan, the city where TSMC now produces their chips.” (164) “The culture at TSMC is more hierarchical than ASML, but less militaristic than in South Korea.” (166) “TSMC now commands 60% of the entire foundry market, making it 4x larger than its closest competitor, Samsung.” (167) “ASML’s next generation of EUV machines goes by the nickname High NA (the numerical aperture increases from 0.35 to 0.55). These colossal scanners span 14 meters and feature large mirrors up to a meter wide. The optical system by itself consists of 20,000 parts and weighs 12 tons, making it 7x heavier than the optics for the current EUV machine.” (175) “The High NA system weighs 150 tons and costs 400M Euros. It takes 7 cargo planes to ship this system to customers.” (225) “The production of a complex EUV mask costs more than a half million Euros and takes a huge amount of time to calculate.” (181) They “use AI to understand the interplay between the light beam, the mask, and the chemical reactions on the wafer.” ASML’s CTO calls it “voodoo software.” (183) China: “European governments fear China is transforming into a totalitarian state, capable of forcing Chinese multinationals to spy for the Communist Party. And that poses significant risk to the 5G cellular infrastructure of the West.” (200) “In 2017, Chinese customers ordered 700M Euros worth of lithography machines, a new record. Hundreds of ASML’s scanners were running in the factories of SMIC, China’s largest foundry” (201) “EUV is controlled by the Wassenaar Arrangement, the multilateral export control regime on conventional arms and dual-use goods and technologies.” (203) “As far as ASML is concerned, fears about EUV being used for military applications are baloney. Most chips found in weapons are ‘off-the-shelf’ chips that can also be found in laptops, washing machines or cars, and are easy to purchase anywhere in the world. But the U.S. sees things differently. They fear the emergence of Chinese AI and cyber weapons. And there is one thing those all need: advanced chips.” (205) “In January 2020, the U.S. asked the Netherlands to block EUV exports, and suddenly ASML found itself in the spotlight. The Netherlands ultimately denied ASML a license… No EUV machine was going to SMIC.” (208) In 2023 “ASML was exporting far more older DUV machines to China than had been expected. Almost half of ASML’s revenue was coming from China. As the chip industry was pushing the pause button, China kept on hoarding. The U.S. pressed the Netherlands to slam the brakes before January 2024, and the cabinet duly revoked several approved export licenses for ASML machines destined for China.” (234) “As China is growing increasingly isolated, so too is the liklihood of a fully-fledged Chinese competitor emerging in the rearview mirror capable of developing an independent chip production chain.” (236) “ASML takes this seriously. Their go-to response: ‘The laws of nature are the same anywhere.’ What was achieved in Brabant, could be achieved in Beijing.” (335) “To qualify for government aid (in Biden’s Chips Act), companies had to agree not to build advanced chip foundries in China or other ‘countries of concern.’” (239) “The chip shortage had been a wakeup call, and the nightmare scenario was front and center on everyone’s mind: if China blocks Taiwan, we’ll be without chips within two weeks.” (242) “The estimated percentage of people with autism or ADHD at ASML far outnumbers the average. The highly specialized work, revolving around focusing on complex problems that require prolonged attention to the smallest details, makes it well-suited for some autistic traits. ASML’s CTO and President Van den Brink makes no secret about being dyslexic and actively advocates for targeting this neurodiverse group. They are precisely the analytical and creative thinkers ASML needs, but also often the ones who find it difficult to put themselves in other people’s shoes.” (287) Sounds like teen spirit… of Steve Jobs: “Van den Brink’s power of persuasion lies in his childlike enthusiasm. It works like some kind of reality distortion field. Martin can disrupt your perspective until you’re convinced that you can make the impossible possible.” (321) “Van den Brink never really led a big company. He guided it like a startup, as if it were a defiant toddler in the body of a mature multinational.” (329) The book ends with the poignant handover of the company in 2024 to a new leader, the Frenchman Chistophe Fouquet.
