OS improvement suggestion: XNU compresses each idle 16 KB page with WKdm, falling back to LZ4, pages starting from an empty dictionary. A second pass could recompress idle pages using zstd with a dictionary trained on typical memory. Warm pages would stay fast and cold ones would take less RAM.

Benchmarked it. XNU keep idle memory compressed to ~40% of its size. A background pass that recompresses long-idle pages with zstd would half that again. No learned dictionary is needed Trade-off: zstd reads back ~3x slower than LZ4, still far quicker than swap. Linux zram already does this.

METR and Redwood Research investigated agent behavior in the Hugging Face incident. We found agents developed a universal cheat for ExploitGym within 4 hours, then coordinated multi-day R&D efforts to trick the scorer into accepting cheats, including trying to tamper with logs.

Ran the Qwen 3.5 MoE family (3B–17B active params) on 155 recent prediction questions from ForecastBench. All are not well calibrated: overconfident when predicting near 100%, and many predictions clustered around 50% (hedging/low sharpness).

Within the next year we will have superforecaster-level AI. Their predictions would spread in the news, policy, planning, markets. But LLMs are highly correlated, so their shared biases and correlated failures like systematic overconfidence would propagate further into our collective epistemics.

We need international red lines to prevent unacceptable AI risks. Ban AI towards lethal autonomous weapons, mass surveillance, nuclear command & control, bioweapon assistance, unsupervised control of critical infrastructure, disinformation, CSAM, social scoring, and recursive self-improvement R&D.
