UNITED NATIONS (AP) — The heads of major artificial intelligence firms pleaded with the United Nations on Wednesday to save the world or at least its people — by somehow regulating the fast-expanding technology that they have been designing.

“If managed poorly, I even believe AI could be a risk to humanity as a whole,” said Dario Amodei, chief executive officer of Anthropic. And from his competitor Sam Altman, CEO of OpenAI, came this assessment: “We could lose control of the future to AI.”

Both said the countries of the world, through the U.N. Security Council, where they testified Wednesday, have to set safeguards of some kind to prevent the technology from getting too powerful to rein in.

They also called for the world to make sure that the power of AI isn’t concentrated in one company or country. They also touted the benefits of the technology for bettering humanity and what Altman called “giving people more power over their own lives.”

Those tech leaders “are telling us in stark terms that it cannot be left to them to prevent disaster from befalling the world,” British Foreign Secretary Ed Miliband said at the Security Council. “We cannot ignore them because they are right.’’

AI will be at the heart of G20 discussions

Miliband said when the U.K. leads the G20 next year, it will put controlling AI at the heart of discussions, looking for a single set of global standards “to insure that AI development is safe.”

But, the United States said: Don’t do it.

Worries about control of AI are “not a reason to pause its further development or to constrain it with new global governance structure,” said White House Science Adviser Michael Kratsios. “We want you, our allies and partners, to share in the benefits of this technology.”

The U.S. and China are jostling for AI dominance — and Chinese U.N. Ambassador Fu Cong emphasized that all countries should be able to choose AI technology as they see fit.

He warned against “banding together into a petty us-vs.-them clique in the tech sector and forcing other countries to take sides” and enabling unnamed major powers that he described as seeking “digital hegemony.” He called on countries instead to promote open-source models — China’s approach to the technology.

For most of the world leaders, one key question about AI is this: Who should control life-and-death decisions — human or machine?

Amodei, Altman and Hugging Face CEO Clément Delangue, who spoke via a glitchy remote connection, spoke with the U.N.’s most powerful council because they and world leaders are trying to figure out not just whether to control AI, but by whom, how it could possibly be done and when it might be just too late.

The day before, U.N. Secretary-General Antonio Guterres warned of “killer robots.” Experts and European leaders said that’s not hyperbole but something that’s either already a grim reality or perilously close.

Amodei called on world leaders to agree on not letting AI build biological weapons, figure out how to verify what models have the capability to do and “establish common standards” for testing and for loss of control and misuse.

French Foreign Minister Jean-Noël Barrot, whose country convened Wednesday’s meeting, compared the current state of AI to both the runaway computer HAL9000 in the movie “2001: A Space Odyssey” and the dawn of the atomic age.

“Just as with the atom back then, the international community must now regulate AI in order to make the most of its potential and avoid the worst,” Barrot said.

Other leaders and nations are paying close attention to AI

His wasn’t the only concern expressed during this high-profile U.N. meeting week.

“We must not allow the cost of today’s hesitation to become tomorrow’s catastrophe,” said Liberian UN Ambassador Lewis G. Brown II.

Ukrainian President President Volodymyr Zelenskyy, speaking at the General Assembly, said some kind of human control over machines must achieved soon. Otherwise, he said, for his country — at war for 4½ years — it may be just too late.

“There is already a real possibility that AI, not only people, will begin to decide what happens on the battlefield. And we need peace before we reach that point,” Zelenskyy said.

Last month, a Russian drone seemingly using AI “autonomously made a targeting decision that killed three Ukrainians. Killer robots are technically easy to build, and they are real. We should not be under any illusions otherwise,” Kentaro Toyama, an information technology professor at the University of Michigan, said in an email.

Data scientist Rumman Chowdhury, co-founder of the accountability nonprofit Humane Intelligence, said the idea of killer robots “evokes a science-fiction villain, when the question I want the public to ask is much more concrete: Who authorized a machine to select and attack a target, under what constraints, and who answers for the result?”

The U.N. meeting unfolded as Chinese President Xi Jinping headed to Washington for a much-anticipated state visit. AI interests are looking to what comes out of Xi’s discussions with U.S. President Donald Trump. Earlier, U.S. Treasury Secretary Scott Bessent said the two countries had discussed a potential new “notification mechanism” for AI incidents that could impact national security.

But on Tuesday, Trump, lauding AI as “superintelligence,” said the United States would reject efforts to control the technology as it tries to win the development race with China. Kratsios was the one of the few who used that term in the Security Council.

Meanwhile, regional groups in Europe, Asia and elsewhere also are trying to coordinate AI policies, and various nations — and even subcomponents, such as U.S. states — are crafting their own.

NASHVILLE (AP) — Dolly Parton ‘s estate accused the country music icon’s nephew of threatening to commit violence and destroy his aunt’s legacy and business empire in court filings submitted Tuesday and asked a judge to keep him away from its employees and business dealings.

Court documents filed in Nashville offer the first signs of discord in a carefully managed estate process for one of the most beloved personalities in music and beyond.

Bryan Seaver, who owns a company that provided Parton’s security detail and was handpicked by the star to announce her death from cancer last month, did not immediately respond to an email from The Associated Press requesting comment.

In the temporary restraining order request filed by She’s Alive, the entity that manages and protects Parton’s professional property and business, and other court documents, it claims Seaver sent increasingly threatening messages over the last several weeks. She’s Alive is run by Danny Nozell, Parton’s longtime manager.

Last week, “She’s Alive” terminated Seaver and Squadron Augmented Protection Services, saying his “terrorizing conduct made their continued retention untenable,” according to court documents.

The court documents showcase a series of text messages and emails She’s Alive says were sent by Seaver starting just before Parton’s death. The messages begin with threats to destroy the brand, and then after her death, depict Seaver reveling in his newfound fame and calling himself an “international arms dealer.”

In one message written on Sept. 1 and included in the court documents, he said: “I’m going to set up a podcast dedicated to ruining Dolly’s brand partnerships and telling the violations these people have done on us. It’s going to be great. Or f——— pay me.”

Seaver also claimed that he worked for private military contractors overseas during the Iraq War and used that experience as part of these threats, according to the complaint.

The messages have resulted in Parton’s trusts and estates attorney leaving and employees of She’s Alive resigning, according to the court documents. The entity has also had to hire private security for its employees, including at their homes, the documents state.

The restraining order is meant to stop Seaver from talking with or being within 1,000 feet (304.8 meters) of She’s Alive employees, attorneys and business partners. It also is meant to keep him from interfering with its business relationships.

Parton wrote hundreds of songs, including classics like “Jolene,” “Coat of Many Colors” and “I Will Always Love You,” that earned a total of more than 100 million worldwide sales and more than 1 billion online streams.

ANCHORAGE, Alaska (AP) — After a summer spent packing away sockeye salmon, Alaska’s heftiest brown bears are ready to throw their weight around.

Online voting began Tuesday for Fat Bear Week, the annual contest that pits the rotund residents of Katmai National Park and Preserve against each other for the title of most oversized ursine.

Last year’s winner, Chunk — known officially as Bear 32 — is hungry for a repeat. Chunk’s weight in 2025 was estimated at 1,200 pounds, which gave him a narrow victory. This year he’s back and facing corpulent competition like Gully — aka Bear 903 — the offspring of two-time champion Grazer.

The contest, which is in its 12th year, celebrates the resilience of the 2,200 brown bears that live in the preserve on the Alaska Peninsula, which extends from the state’s southwest corner toward the Aleutian Islands. The animals gorge on the abundant salmon that return to the Brooks River, sometimes chomping the fish in midair as they make their way upstream to spawn.

The event this year features 16 bears facing off in a single-elimination, bracket-style tournament. All voting is done online at www.fatbearweek.org, with the winner declared Sept. 29. The public can watch the bears on explore.org’s livestream cameras before deciding on their favorite.

“Fat bears are successful bears,” the nonprofit’s website says. They gorge on salmon starting in late June in order to accumulate fat reserves to prepare for winter hibernation, when they do not eat or drink and lose one-third of their body weight.

Adult male brown bears typically weigh 600 to 900 pounds (about 270 to 410 kilograms) in midsummer. By the time they are ready to hibernate after feasting on migrating and spawning salmon — each eats as many as 30 fish per day — large males can weigh well over 1,000 pounds (454 kilograms). Females are about one-third smaller.

Voters in the online contest can review before-and-after photos of the bears, lean at the start of summer and fattened at the end. The bears are not actually weighed — imagine that process — and some fans choose their favorite based on their looks or backstory.

To be featured in the contest, the bears must frequent the area around the river.

The live cameras at Brooks Falls captured the moments in 2024 when mother bear 128 Grazer ’s cub slipped over the waterfall and floated into the fishing spot occupied by Chunk, who attacked and injured the cub. Grazer fought Chunk, but the cub ultimately died. After the dramatic fight, voting fans handed Grazer a victory over Chunk. Then Chunk returned in 2025 to take the title.

Fat Bear Week was started in 2014 as an interactive way to inform the public about brown bears, the coastal cousins of grizzlies.
