June 5: Anthropic has called on top-tier artificial intelligence labs worldwide to consider slowing their research and development efforts, noting AI systems are evolving at breakneck speed and may soon gain the ability to improve themselves without human intervention—a capability that could pose major societal risks. In a recent blog post, Anthropic published internal data vividly illustrating how its most advanced models are boosting performance at an astonishing rate. The piece suggests AI progress is moving toward "recursive self-improvement," where systems can autonomously optimize themselves without any human input. It called for a global agreement to potentially slow the pace of AI research, alongside a mechanism to verify that competitors comply with such a deal. In response, Serenity framed the call as a competitive ploy designed to freeze rivals while advancing its own work, arguing that such demands might instead prompt countries to accelerate AI investment. This, Serenity

**Tariff Refund Legal Fight Escalates After Federal Trade Judge’s Rare Public Action** June 5 — A federal trade judge made an unusual public statement this week regarding the Trump administration’s appeal of a tariff refund ruling, as the legal battle over refund authority continues to heat up. U.S. Court of International Trade Judge Richard Eaton released a public letter Wednesday directly pushing back against the U.S. Department of Justice (DOJ)’s appeal of his order. In the letter, Eaton challenged the government’s legal position and warned that appellate court interference could disrupt an online refund system that has already processed at least $85 billion in refunds. DOJ responded the same day, stating it established the online refund system under its “own authority” to distance the program from Eaton’s tariff refund decision. The core argument in DOJ’s official appeal, filed this week, is twofold: First, Customs and Border Protection (CBP) has no legal right to reopen cu

June 5 — According to three sources familiar with the matter, senior U.S. officials have held preliminary talks with several large artificial intelligence firms over the possibility of the U.S. federal government taking equity stakes in these companies. Two independent sources share that Sam Altman, CEO of OpenAI, has raised this idea multiple times with top Trump administration officials since the start of Trump’s second term. Both sources spoke on condition of anonymity due to the sensitive nature of internal talks. They further stated that Altman first floated the concept directly to President Trump in an early 2025 meeting and has revisited the proposal with administration officials in recent weeks, aiming to distribute AI-related economic gains more widely to the general public. Anthropic, another major AI giant, has not engaged in any discussions with the government about offering equity to the federal side, the sources added. Insiders revealed that while the plan is still bein
