Bowen Zhou, Director and Chief Scientist of Shanghai AI Laboratory，asked Nicholas B. Dirks whether external evaluations, red teaming, and third-party verification were enough to justify handing real-world authority to AI.

"No," Nitzberg replied.

He compared AI systems to bridges. Engineers do not build a bridge first and then attack it to discover whether it is safe. The builder carries the burden of proof during design. Increasingly powerful agents, Nitzberg argued, should likewise be safe by design, with evidence before deployment that their overall behavior remains understandable and controllable.

That is why AI safety has become urgent now. Rules in aviation, finance, and medicine have often followed air crashes, financial crises, or public-health disasters. But AI cuts across all of those sectors. Its speed, scale, and cross-border reach make disaster an unacceptable starting point for governance.

Nicholas B. Dirks pointed to a second difficulty: People are already using systems they do not trust, and adoption will continue to grow. Engineering verifiability does not automatically become social trustworthiness. Trust also requires independent oversight, clear responsibility, continuous monitoring, and assessment at every stage of deployment.

The word "agent" carries two very different meanings.

In AI, an agent is a system that can perceive, plan, and act. In law, an agent receives authority but also assumes a duty of loyalty and can be held accountable. Today's AI agents can receive the first of those things. They cannot assume the rest in the way a person or company can.

Authority is beginning to flow to machines while responsibility remains in human society.

Mark Nitzberg, the Executive Director of the Center for Human-Compatible AI and Head of Strategic Outreach at Berkeley AI Research，described this as a gap between engineering and law. A human agent who fails in a duty can be investigated and sanctioned. A probabilistic black-box system has no engineering equivalent of a fiduciary duty. Closing that gap, he argued, requires AI that is well-founded, legible, and steerable: built from components people can reason about, understandable in operation, and stoppable or changeable at any time.

Lan Xue，Dean of Schwarzman College and the Institute for AI International Governance at Tsinghua University，noted that classic principal-agent problems have not vanished. Information asymmetry, moral hazard, and misaligned objectives all persist. What has changed is the accountability chain. A machine cannot be punished, so responsibility must be redistributed across design, development, deployment, and use.

Nicholas B. Dirks, President and CEO of The New York Academy of Sciences，warned that delegation is never only about handing off a task. In the pursuit of efficiency, people may also delegate goals, judgment, and principles. "If we are only thinking about AI that way," he said, "we are already beginning to forget about our values."

🚀 Introducing Spatial-SSRL, the first study which proposes a Self-Supervised Reinforcement Learning paradigm for spatial understanding.
💡 Spatial-SSRL a lightweight tool-free framework that aims at enhancing spatial intelligence and is natually compatible with the RLVR training paradigm. Only raw 2D and RGB-D images are required and we avoid any use of human annotation, external proprietary model or expert model throughout the entire pipeline, making Spatial-SSRL highly cost-effective and scalable.
🛰️ Spatial-SSRL comprises five pretext tasks now: shuffled patch reordering, flipped patch recognition, cropped patch inpainting, regional depth ordering, and 3D relative position prediction. Thanks to its lightweight characteristics, Spatial-SSRL can be easily extended to more pretext tasks and we welcome the whole community to join Spatial-SSRL with effective pretext tasks!
🤖 After applying Spatial-SSRL, we significantly enhance the performance of spatial understanding on Qwen2.5-VL (3B&7B) and Qwen3-VL (4B), as well as retaining their general visual capabilities.
🤗 Currently, we have released the repository of Spatial-SSRL, the dataset Spatial-SSRL-81k, and the trained models: Spatial-SSRL-7B and Spatial-SSRL-Qwen3VL-4B. The total download of the models and dataset has surpassed 1,000.
