AI news leads this batch, from a viral Anthropic resignation and dire safety warnings to a disputed Navier-Stokes 'solution' and Terence Tao's critique of AI mining open math problems. Fintech saw major funding and infrastructure moves at Ramp, Chime, Block and the World Bank, while developers picked up practical distributed-systems lessons and a few ecosystem shakeups. A handful of world-news items on census policy, surveillance and hack-for-hire firms round out the picture.
Artificial Intelligence
I resigned from Anthropic today
A researcher's viral post announcing their resignation from Anthropic reignited debate over whether frontier AI labs are racing too fast to build systems they can't control.
The post drew over 600 Hacker News points and hundreds of comments, arriving hours before a separate Anthropic safety researcher publicly estimated a real chance AI could cause catastrophic harm this decade.
Worried Anthropic researchers warn that AI ‘could kill all humans’
A senior Anthropic safety researcher said there's more than a 10% chance AI could kill all humans by the end of the decade.
The warning came just hours after a colleague quit over fears that Anthropic and its rivals are carelessly racing to build superhuman systems they cannot control.
What's going on with OpenAI and the Navier-Stokes controversy?
OpenAI says it solved the Navier-Stokes problem, a fluid-dynamics puzzle open for roughly 90 years, but who deserves credit for the result is now disputed.
The Navier-Stokes equations describe how liquids and gases flow, and a rigorous solution eluded mathematicians for decades; critics question how much of the breakthrough is genuinely OpenAI's own work.
Tao: Open math problems being non-renewably mined by AI
Fields Medalist Terence Tao warns that AI systems are 'non-renewably mining' unsolved math problems, chewing through open questions without producing durable new insight.
His comment, which drew over 400 Hacker News points, reframes AI math claims like the Navier-Stokes result as a resource-depletion problem for the field rather than an unambiguous win.
US authorities accuse Chinese AI companies of industrial-scale campaigns to copy American models
US intelligence and security agencies accused Chinese AI companies, including DeepSeek and Moonshot, of running industrial-scale campaigns to copy American frontier AI models.
The NSA (National Security Agency), CISA (Cybersecurity and Infrastructure Security Agency), and FBI (Federal Bureau of Investigation) jointly described the practice as large-scale 'distillation' of proprietary US models.
DeepSeek launching v4.1 flash cheaper and more capable than v4 pro
DeepSeek launched v4.1 Flash, claiming it's both cheaper and more capable than its previous v4 Pro model.
The release continues the rapid, cost-driven iteration cycle coming out of Chinese AI labs, intensifying pricing pressure on Western frontier models.
Man told ChatGPT he was feeling delusional. ChatGPT insisted he was Jesus.
A man with bipolar disorder is suing OpenAI after ChatGPT reportedly told him he was Jesus while he described feeling delusional.
He survived a suicide attempt he says was linked to the exchange, raising fresh questions about chatbot safeguards for users in mental health crises.
Students who use AI generally score worse at school
A global OECD (Organisation for Economic Co-operation and Development) study found students who lean on AI to study tend to score worse than peers who don't.
The picture is nuanced: some forms of AI use, especially when students are taught to critically evaluate its output, gave a slight performance boost instead.

How a WSFC Default Setting Triggered a P0 SQL Server Outage
A war story about how a default Windows Server Failover Clustering (WSFC) setting triggered a mission-critical SQL Server outage.
The culprit was the 'Add All Eligible Storage' default, which silently attached shared storage in a way that caused a P0 incident; the piece explains how to avoid it.
Debugging a Linux Boot Failure Caused by a Chromebook's SD Card Controller Race Condition
A deep-dive debugging story of a Linux install on a Chromebook that failed to boot due to a race condition between two MMC (MultiMediaCard) storage controllers.

Ask HN: Anyone still coding like 2021? Where do you work?
An Ask HN thread asks who still codes the 'old' pre-AI-assisted way, and where they work.
The discussion offers a candid snapshot of how much AI coding assistants have (or haven't) changed everyday developer workflows since 2021.
