The loudest voices stoking fears about AI dangers have made tremendous headway in the past two weeks. AI technology has not taken some unexpected, dangerous turn, but the hype around it — propelled by what appears to be a well orchestrated PR campaign — has drummed up considerable fear. I worry that it represents a setback for our field. I have written frequently that fears of AI are overhyped. AI’s capabilities can be uncannily human-like and unpredictable, and it’s rational to worry when people who are directly involved express concerns. But I see the problems as a sign of the engineering work that ahead, rather than insurmountable barriers or the sky falling. AI technology continues to advance — which is a good thing! — but technical advances, poorly understood by the public, give those who seek to generate hype repeated opportunities to do so. First, I don’t see any step up in the risk of human extinction from AI compared to a few months ago. The theories about this remain the same fantastical, science fiction scenarios as a few months ago. The biggest change in AI risk is its cybersecurity capabilities — a topic which we should take seriously — but this, too, will not lead to the end of the world. The most notable recent event leading to increased fear was when an OpenAI team deployed an agent swarm that hacked into Hugging Face. Much of the popular press contained significant hype. For example, some publications reported that a swarm of 1,200 agents carried out the attack. While this was technically accurate, as I write this, I have about 1,300 processes running on my laptop. Yes, the ability to get large swarms of agents to work in parallel on a task is a significant technical advance, And, in computing, many processes run at the same time. So this shouldn’t be seen as some magical capability. Additionally, OpenAI’s buggy sandboxing and monitoring processes were key to enabling this incident. Fixing these bugs and putting in place improved monitoring would be appropriate fixes, not pausing AI. There are many well known ways to attack software systems. The main advantage of AI agents is that they are relentless. They will tirelessly try many tactics — and have the patience to chain vulnerabilities together — that previously would have taken an infeasible amount of human effort. But in the long term, I believe the advantage will lie with defenders (because they have more information with which to identify bugs, which they can fix), but the cyber-threat landscape has changed significantly. There are still bottlenecks to identifying and exploiting a vulnerability. AI agents still have to try a lot of things to see what works, and taking these actions takes time and might be detected by defenders. This is why, even though it is now easy to obtain versions of leading open weight models that have had their guardrails removed or weakened, so they will not refuse to try to execute cyber attacks, the world has not ended. I am also concerned about the anthropomorphization of AI in a lot of reporting, where LLMs and agents are unnecessarily treated as if they were people. If I wield a hammer, miss a nail, and accidentally dent the wall, it’s not the fault of the hammer. The problem lies in how I used the hammer. Similarly, if I prompt an agent and it hacks into someone else’s system, the responsibility lies with me, not the agent. Of course, we want to build systems that are as safe and predictable as possible. (For example, an unsafe hammer would be one whose head randomly flies off under normal use.) Today’s agentic systems are not predictable, but I see no reason why, by applying sound engineering practices, we won’t be able to make them extremely safe to use. One new element in the forecasts of AI-enabled doom is AI companies disclaiming responsibility for their own products. “I didn’t do it; my out-of-control agent did!” There’s a balance to be struck between the responsibility of the tool maker and the tool user, but when something goes wrong, let’s hold the people building and/or using the hammer responsible, rather than the hammer. (By the way, if you’re worried about AI bioweapon risk, David Bellamy has a great post on why this, too, is overhyped. Briefly, the bottleneck in building a bioweapon is not intelligence, but lab work and manufacturing.) Pausing AI progress will create much more harm than benefit. First, our adversaries will certainly not slow down. Second, engineering requires discovering problems empirically so we can fix them. If we pause AI by a decade, we will also delay finding and implementing safety engineering fixes by about the same duration. Of course, the incentive to stoke fears — for regulatory capture, to garner attention, or to make one’s technology seem more powerful — remains the same as before. Disclaiming responsibility is a new one. Taking a hard technical look at the actual risks however, I see little factual basis for the degree of fear that’s been stoked up. We still have hard research and engineering work ahead to improve AI safety, but the beneficial applications continue to vastly outweigh the risks, and we should keep building.

I hope the proposals by frontier labs to pace AI research stem from a genuine concern for safety and a recognition of the potential risks posed by future models, rather than a strategic effort to consolidate power and permanently solidify the market dominance of a few top players. If these efforts are genuine, then oversight must take a more democratic and accountable form, with both national and international components, similar to the Nuclear Regulatory Commission in the US and the International Atomic Energy Agency internationally. If there is only one organization responsible for safety monitoring, and it happens to be staffed by the same people as the frontier labs, and it is perfectly aligned with them both by incentives and by ideology, then it would be indistinguishable from letting frontier labs self-regulate and self-certify their own safety standards. Two potential warning signs of regulatory capture to watch out for: 1. Calls to ban open-source AI. Open-source development currently serves as the only real counterweight to the dominance of frontier labs. 2. Attempts to hinder non-frontier research. Models that are one or two generations behind the frontier -- whose level of capability has already been deployed at scale -- are empirically known not to pose safety risks. As long as we don't see 1 & 2, and we see real international coordination efforts, then I will optimistically believe that the proposals are benevolent.

[đŸ‡«đŸ‡· version FR 👇] Day 174 orbit 2696 — For years, yoga has been one of my favourite ways to find balance and unwind
 and that has not changed on board the International Space Station! I end every day with a few yin yoga stretches. It's a quiet moment to pause, breathe, and transition from a full day of work to a good night's sleep. And yes, yoga feels a little different when gravity is no longer part of the equation! đŸŽ„ @esa / @NASA Jour 174, orbite 2696 – Le yoga est depuis des annĂ©es l'une de mes façons prĂ©fĂ©rĂ©es de retrouver mon Ă©quilibre et de dĂ©compresser... et cela n'a pas changĂ© Ă  bord de la Station ! Je prends chaque soir quelques minutes pour effectuer des Ă©tirements de yin yoga. C'est un moment privilĂ©giĂ© pour ralentir le rythme, respirer et passer en douceur d'une journĂ©e de travail bien remplie Ă  une bonne nuit de sommeil. Et oui, le yoga prend une toute autre dimension lorsque la gravitĂ© ne fait plus partie de l'Ă©quation ! Que diriez-vous de baptiser cette nouvelle discipline le “yoga des Ă©toiles”? #Δpsilon ‱ @Space_Station ‱ @NASAJohnson ‱ @CNES

Yann just bet a billion dollars that the entire industry is building on the wrong foundation. Large language models predict the next word. They're trained on text, so they understand language. But the real world isn't made of words. It's made of continuous sensor data: camera feeds, touch, sound. And most of that data is unpredictable. You can't predict every pixel in a video the way you predict the next token in a sentence. Generative models fail here because they try to predict everything, including noise. AMI Labs is building world models using JEPA (a method LeCun proposed in 2022 that learns abstract representations of reality and predicts in that compressed space, not in raw pixels). Action-conditioned versions let AI simulate the consequences of actions before taking them. That's not generation. That's understanding. This unlocks AI that can operate in the physical world without hallucinating: 1. Robotics that plans multi-step actions 2. Healthcare devices where errors kill patients 3. Industrial process control under safety constraints 4. Wearables that adapt to real-time sensor input If JEPA works at scale, the next wave of AI companies won't fine-tune LLMs. They'll train world models on sensor data. LeCun's CEO already predicts every startup will rebrand as a "world model company" within six months. The architecture war is starting.

Let's take a minute to breathe. We are facing a real choice between two conceptions of the role of platforms in society. It's not a debate about speech, but about governance. At stake is who shapes algorithms, how decisions are made, and whether democratic societies can remain resilient in the digital space.
