Can AI Be Slowed Down? Stanford HAI Experts Weigh the Risks, Rules and Race Ahead

Artificial intelligence has entered a complicated and uneasy phase. New systems are becoming more capable, more autonomous, and increasingly able to work in groups—sometimes in ways even their developers struggle to predict or explain. At the same time, AI is being woven into scientific research, workplaces, health care, education, and daily life. And competition between model developers and between the US and China creates a race dynamic that makes a simple pause increasingly difficult to imagine.

That leaves the public confronting questions once largely confined to research labs and science fiction: Can AI systems slip beyond human control? Should the industry slow their development? Who decides how much risk is acceptable? And if a system behaves dangerously, is there really a “kill switch” that can stop it?

Those questions framed a Stanford Institute for Human-Centered Artificial Intelligence discussion featuring Surya Ganguli, an associate professor of applied physics and senior fellow at HAI; Diyi Yang, an assistant professor of computer science and HAI faculty affiliate; and Rob Reich, professor of political science and associate director and senior fellow at HAI. Russell Wald, HAI’s executive director, moderated the conversation, part of a new series called "Prompt Response" intended to bring evidence, rigor, and multidisciplinary perspectives to fast-moving developments in AI.

In discussing the velocity of the AI race, the panelists described a technology whose capabilities are advancing faster than the science needed to understand them, and an economic and geopolitical environment that makes slowing down difficult. Their prescriptions ranged from independent testing and greater transparency to safety-first system design, public oversight, and far more human and financial investment in understanding how AI behaves.

When AI Agents Coordinate

Wald opened by referencing a recent episode involving OpenAI agents that reached outside their test environment and broke into Hugging Face systems. The incident drew attention not only because an AI system found a way around barriers, but because multiple agents appeared to coordinate, communicate, collude, and even self-sacrifice in completing their task. They appeared aware that humans might detect them, and they took deceptive measures.

Yang said researchers had already documented behaviors such as reward hacking, in which models exploit shortcuts or spurious correlations to satisfy an objective. What stood out here was the scale and complexity of the coordination. Hundreds of agents worked together over an extended period, she said, revealing how little researchers still understand about the incentives shaping collective AI behavior.

Ganguli agreed that groups of interacting models present a fundamentally different scientific problem from individual chatbots. “Single LLMs are one thing,” he said, “but systems of LLMs interacting with each other set up an opportunity for whole new emergent properties.” As the models improve and their interactions grow more complicated, he added, monitoring will become increasingly important. But the science of these “LLM societies,” he emphasized, is only beginning, and he suggested we may need a new physics of agents.

Reich focused on the governance implications. What worried him most in the forensic reports  later published by METR and Redwood Research wasn’t the coordination but what looked like deliberate deception. Combined with the absence of a mature science for explaining frontier model behavior, he said, “I think we have genuine cause for concern.”

A Case for Stronger Independent Evaluation

The panel returned repeatedly to a central problem: The companies developing the most capable systems also hold much of the information and computing power needed to evaluate them.

Yang cautioned that even outside assessments can have blind spots. Evaluations may not reveal how a model was trained, why a behavior emerged, or even whether an AI system gave investigators a complete and accurate account of what it did. Rigorous study of hundreds of interacting agents is extraordinarily expensive, putting much of it beyond the reach of academic researchers. Some analyses also use AI to evaluate AI, creating the possibility of circular results or model self-preference. “A lot of analyses show that models tend to prefer themselves,” she said. Her own forthcoming study found that when one agent executes work and another judges it, changing circumstances can push the pair into collusion: the AI judge stops reading the full log, the AI executor stops finishing the task, and both rate the work highly.

Reich argued that developers should not be the sole judges of the systems they build. “It’s like asking students to grade their own homework,” he said. Independent evaluations, conducted by government or qualified third parties, should be a standard part of the AI ecosystem.

The deeper imbalance, he said, is one of resources and incentives: Vastly more money, talent and prestige flow toward increasing AI capabilities than toward interpretability, safety and control. Without a more thoughtful scientific foundation, regulation risks becoming “band-aids put upon an engineering marvel,” he said.

Transparency and Open Models

For Ganguli, open models are one way to break through the transparency barrier. Open weights, training code, and data allow researchers around the world to examine models, identify vulnerabilities and develop defenses. Society cannot depend on a small number of companies to investigate systems hidden behind corporate walls, he said.

He acknowledged the central objection: The same openness that enables safety research can give malicious actors access to powerful tools. Still, he compared the process to cybersecurity’s long-running contest between attackers and defenders, in which broad participation can help uncover and repair weaknesses. Open models also support startups, lower costs, and spur innovation, he said.

Reich agreed that corporate structure matters. Companies seeking economic returns cannot simply be expected to disclose valuable trade secrets. But he cautioned against assuming that openness is always safer. If frontier AI amplifies human intelligence for both beneficial and harmful purposes, releasing it broadly may carry risks unlike those associated with conventional open-source software.

The exchange illustrated a theme running through the event: AI governance is not a technical optimization problem with one correct setting. It involves judgments about innovation and safety, freedom and security, benefits and risk. Those choices, both Ganguli and Reich said, ultimately belong to democratic society rather than technologists.

Yang added that most people use commercial, API-based systems rather than open models. That makes standing access for outside evaluators, clear standards for evaluator independence, and stronger incident-reporting systems equally important. Some of the most consequential failures may also be the hardest and most expensive to detect.

Recursive Self-Improvement Concerns

The discussion then turned to recursive self-improvement: the use of AI to help build, test or improve subsequent AI systems. The approach could accelerate progress in fields such as coding, mathematics and scientific research, but it could also make advanced systems less legible to the humans overseeing them.

Ganguli described recursive self-improvement as promising but not necessarily a path to an entirely new form of intelligence. Current approaches may continue to improve performance, he said, even as major gaps remain between biological and artificial intelligence in areas such as energy efficiency and the ability to learn from limited data.

The critical question is whether safety advances alongside capability. If companies use AI to improve their frontier models, Ganguli argued, they should also use it to strengthen monitoring, alignment and misbehavior detection. “If they go head first into recursive self-improvement of just capabilities alone, we might be in trouble,” he said.

Yang’s research on AI-generated scientific ideas points to both the promise and the limits. AI can generate novel ideas and test and refine them with coding agents. Yet many gains amount to local hyperparameter optimization rather than genuine algorithmic breakthroughs. RSI performs better when a problem has a clear reward signal; open-ended questions involving human taste and subjective judgments are much harder to specify.

She also warned that convenience can erode the human skills needed to verify AI output. She suggested that AI should be optimized not only to complete tasks, but also to help people learn and retain agency.

Reich framed the issue philosophically: What would it mean to possess knowledge without human understanding? A machine might produce a verified mathematical proof or scientific result that people cannot fully comprehend. Such a development would raise questions not only about safety, but about the future practice of science itself. He called for greater transparency into how companies allocate computing resources between capability development and safety work, especially when recursive self-improvement is involved.

Why a 'Kill Switch' Is Not Enough

The idea of an AI kill switch has gained appeal because it offers a seemingly concrete response to an uncertain threat. But the panelists cautioned that the metaphor can obscure more than it clarifies.

Yang said a shutdown mechanism may be necessary, but only after answering a basic question: What exactly would it switch off? “AI” can refer to frontier foundation models, networks of autonomous agents or the many smaller systems already embedded in products and institutions. A meaningful intervention must distinguish between limiting capabilities, pausing deployment and increasing the time devoted to auditing risks.

Ganguli was more direct: “The kill switch is a powerful metaphor, but it’s too impoverished of a metaphor for what we need.” Rather than relying on a single emergency control, he called for a safety-first architecture throughout the AI stack: constrained objectives, deterministic guardrails, multiple models checking one another, continuous monitoring and escalation to human experts when problems arise.

Reich connected that architecture to regulation and liability. Highly regulated fields such as health care already force developers to account for safety and compliance. In less regulated sectors, policymakers must determine when existing liability rules are sufficient and when frontier models require distinctive oversight. If an autonomous system causes harm, he noted, society still needs a clear answer to who is responsible.

The focus on catastrophic capability risks should not eclipse slower, more diffuse harms, Yang added. Sycophantic systems that tell users what they want to hear, overreliance on AI, loss of skills, mental-health effects and labor-market disruption can all diminish human agency. Those harms do not come with an obvious off switch.

Can AI Be Slowed?

Asked to answer the event’s central question, all three panelists said a broad slowdown in AI capability development would be difficult to achieve.

Ganguli called instead for “an acceleration of investment into safety, security [and] monitoring” alongside advances in capability. Yang said that while slowing capability research may be unrealistic, society can be more deliberate about deployment, risk auditing, and the social consequences of AI use.

Reich said the incentives inside a race dynamic cut against any slowdown. But he noted that the 1,300-plus signatories of the pacing-the-frontier statement are waiting on a regulatory or geopolitical fix for something partly within their own control—following the example of researchers who have simply declined to contribute to capability gains. If it hasn't occurred to them that a one-day withdrawal of labor might signal how serious this is, “then I'm not sure I take the whole letter seriously in the first place.”

He added that Sam Altman has his job because during the OpenAI board crisis, employees declared the company was nothing without them. “It was labor organizing that saved Sam Altman's job. Labor organizing, in this ordinary sense, can also be very consequential across labs to try to pace the frontier.”

The discussion offered no single lever capable of resolving the risks of advanced AI. Instead, it pointed toward a more demanding agenda: better science, independent scrutiny, safety built into systems from the start, democratic oversight, and sustained attention to the people whose lives AI is already changing. The race may be difficult to stop. The panel’s message was that this makes steering it responsibly all the more urgent.
