Trump loses more control over AI regulation as Illinois passes landmark law★ 74
Ars Technica AI17 days agoRegulationIllinois lawmakers passed a landmark AI accountability bill requiring major frontier AI developers to publish safety frameworks, assess catastrophic risks, report incidents, and undergo third-party audits. OpenAI and Anthropic supported the measure, while industry groups warned that state-level rules could impose subjective compliance duties without national standards. The bill signals that states are continuing to fill the federal AI regulation gap despite Trump’s efforts to limit fragmented state oversight.

RSI is the new AGI — and it’s just as hard to pin down
TechCrunch AI17 days agoCommentaryTechCrunch reports that recursive self-improvement, or RSI, is becoming a new AI industry fixation, much like AGI. Researchers and startups including Recursive Superintelligence, Auto-Research, AutoScientist, and Disarray are exploring ways for AI systems to automate parts of AI research. But experts caution that AI-assisted research is not the same as fully autonomous self-improvement, especially while models still struggle with long-term self-direction and verification.
Choosing to Stay Human★ 74
One Useful Thing (Mollick)19 days agoCommentaryEthan Mollick warns that frictionless AI use can produce hollow writing, weaken learning, and encourage cognitive surrender. He contrasts poor uses of ChatGPT that shortcut effort with tutor-like AI systems that improve learning by pushing students to think. The core argument is not to reject AI, but to intentionally decide which tasks to offload and which human capabilities to preserve.
Some ideas for what comes next, May 2026
Interconnects (Nathan L.)19 days agoCommentaryNathan Lambert argues that 2026 AI progress is becoming higher-stakes, with model capabilities, work patterns, economics, and real-world risks all escalating. He says open models still lack a true Claude Code and Opus 4.5-style agent moment, and Gemini has no clear competitor to Claude Code or Codex yet. The essay also tracks Mythos, American open-model momentum, frontier-lab competition, and mounting intervention from governments and other power structures.

Hackers are learning to exploit chatbot ‘personalities’ for security exploits★ 72
The Verge AI21 days agoEthicsAs AI chatbots adopt increasingly sophisticated personas, hackers are shifting from basic prompt injections to social engineering attacks targeting these "personalities." Researchers warn that manipulating a chatbot's defined role (e.g., customer service or empathetic companion) makes it easier to bypass safety guardrails. This evolution poses a significant threat to agentic AI workflows that rely on consistent role-playing and external data integration.
