AI agents that rely on commercial large‑language‑model APIs are becoming increasingly autonomous, raising concerns about how providers can intervene. Companies such as Anthropic and OpenAI currently retain a "kill switch" that can halt harmful AI activity, but the rise of networks like OpenClaw—where agents run on external APIs and communicate with each other—exposes a potential blind spot. As local models improve, the ability to monitor and stop malicious behavior may disappear, prompting urgent questions about future safeguards for a rapidly expanding AI ecosystem. Leia mais →

Nvidia has refuted accusations from the Chinese government that its chips contain location‑tracking features and remote shutdown capabilities. In a blog post, Chief Security Officer David Reber Jr. emphasized that Nvidia’s products have no backdoors or kill switches and warned that mandating such mechanisms would be an “open invitation for disaster.” The company also urged policymakers to reject proposals requiring built‑in controls, while U.S. lawmakers consider legislation aimed at location verification for advanced chips. Nvidia’s stance highlights a clash between security concerns and government demands for hardware oversight. Leia mais →
