Employees at OpenAI and Anthropic are circulating a petition urging the US government to support a mechanism to deliberately regulate the pace of AI development to prevent it from advancing too quickly. The petition, shared among staff at several leading AI labs and seen by media, calls on the US to back an international initiative to govern the build-out of more advanced AI systems. It warns AI progress may outpace humans’ ability to understand or control it, poses "real risks", and cites advances in automating AI research. The petition states: "The US government should support international cooperation to develop the technical and governance tools necessary to target regulation of frontier automated AI development."

7月27日,巴菲特指数(沪深300市值/GDP)轻微升至90.23%,接近年内低位;股债性价比指标——沪深300指数股权风险溢价(ERP)回落至5.19%,7月以来基本保持在5.2%附近波动,处于2024年10月以来波动区间下端,暗示目前股市相对国债收益的优势一般。 -------- 注:1、巴菲特指数是通过将股市总市值和GDP来比较,判断目前股市是否高估,通常70-100%为正常估值,低于该区间为低估,高于该区间为高估。 2、沪深300指数风险溢价(ERP)主要对比沪深300收益和国债收益率,统计近10年数据可以发现该指标和股指有明显反向关系,每次股市都处于底部区域时,风险溢价均超过6%,也就是当ERP≥6%,股市有投资性价比,而当ERP≤4%时,则股市往往接近或处于阶段性高点,投资性价比低甚至要小心回调风险。

The figures are preliminary and may be revised; the agency said "84 cm can be considered a fairly large crustal deformation."
