标普将软银集团评级展望从稳定调整至负面，称该公司对OpenAI追加300亿美元投资的计划可能会损害其流动性及其资产的信用质量。此次展望调整之前，软银上月决定深化对OpenAI的投资，此前已向其投资超过300亿美元，并向其他人工智能企业投资。标普确认软银“BB+”长期发行人信用评级，称软银可能通过出售资产来限制负面财务影响。该评级机构2月3日在一份声明中表示，“软银在人工智能领域的投资，包括对OpenAI的投资，主要涉及我们认为面临重大人工智能创新风险和激烈竞争的初创企业和私营公司。我们认为OpenAI是其信用质量最差的投资之一。”（新浪财经）。clash下载 - clash官方网站对此有专业解读

here’s a subtle but important consequence: in RE#, rewriting your regex using boolean algebra is always safe. factor out common prefixes, distribute over union, apply de Morgan’s laws - the matches won’t change. your regex is a specification of a set of strings, and the engine faithfully finds the leftmost-longest element of that set in the input. no surprises from alternation order, no “well it depends on how PCRE explores this search tree”. just set theory.
