AI Chiefs Warn of Reckless Speed as Markets Shudder

When the founders of the world's most powerful AI companies say the industry is moving too fast, investors take notice — and sell.

On a Monday morning in New York, something unusual happened: the people who built the artificial intelligence boom began arguing publicly that it should slow down. Dario Amodei, chief executive of Anthropic, appealed at the weekend for the AI industry to exercise restraint, warning that "building too fast is reckless." He was not alone. Leaders at OpenAI and SpaceX voiced similar concerns, suggesting that the technology could soon develop in ways that become genuinely difficult to control.

Markets, which had spent years betting enthusiastically on AI's limitless future, responded with something closer to alarm. The sell-off was swift and broadly felt. Nvidia, currently the world's most valuable company and the dominant supplier of chips that power AI systems, closed down 3.3%.

Advanced Micro Devices fell 4%, while Micron Technology and Sandisk each dropped 5%. Across Asia, SoftBank — the Japanese conglomerate that is one of OpenAI's largest backers — slumped a striking 13%. In Europe, the Dutch semiconductor equipment maker ASML, the continent's biggest company by market value, shed 6%. Even Taiwan Semiconductor Manufacturing Company, which supplies chips to virtually every major AI developer, declined 1.

2%. The Nasdaq index, a broad measure of technology stocks, ended the day down 0.5%. Not everyone agreed with the mood.

US scraps power plant emissions limits

On a single day in Washington, the Environmental Protection Agency announced plans to eliminate every remaining federal cap on greenhouse gas emissions from American power plants — the sector responsible for roughly a quarter of the country's total climate pollution. The move arrives precisely as AI data centres, electric vehicles, and a manufacturing revival are pushing electricity demand sharply upward, meaning dirtier power will serve a hungrier grid. The EPA argues that such pollution is "global in nature" and therefore outside its regulatory scope — a position that sits uneasily with the scientific consensus on fossil fuels and climate change, and with the fact that the United States has historically emitted more greenhouse gases than any other nation on Earth.…

Trump Calls Huang Onstage, Dismisses AI Slowdown

During a live appearance at the All-In Summit in Los Angeles, Nvidia CEO Jensen Huang received an unexpected call from President Donald Trump — one he put on speaker for the entire audience to hear. The two aligned publicly against calls to slow AI development, which Anthropic's Dario Amodei, Elon Musk, and Sam Altman have each supported. Trump dismissed the sentiment as "a hoax," suggesting it serves China's interests rather than America's. What makes this moment striking is the gap it reveals.…

2GRAMMAR FOCUS
Wish and if only — expressing regret
Use 'wish' or 'if only' + past simple to express regret about a present situation, or + past perfect to express regret about a past event. These structures signal that the speaker wants reality to be different.

  1. Many investors wish they how fast AI stocks would fall on that Monday morning.
  2. Environmental campaigners say: if only the EPA the emissions limits instead of eliminating them.
  3. Nvidia shareholders wish the sell-off so swift and broadly felt across global markets.
  4. Critics of the Trump administration wish there a stronger independent guardrail on AI development.
  5. Health advocates wish politicians to the scientific consensus on fossil fuels much earlier.
  6. Some tech leaders wish the industry the pace of AI development before markets began to shudder.

4CRITICAL THINKING
The EPA argues that because greenhouse gas pollution is 'global in nature,' it falls outside American regulatory responsibility — yet AI leaders at the same moment are calling for global governance of their technology. What does it reveal about a government's priorities when it rejects international responsibility for pollution while simultaneously pushing for national advantage in AI?

Some of the same technology executives warning about AI's dangers are also among its biggest commercial beneficiaries. Does that conflict of interest make their warnings more or less credible — and does it change how governments and the public should respond to them?
