China Frets Over Nvidia H20 AI Chips, Nvidia Denies Any Backdoors or Tracking Hardware
'When a type of chip is neither environmentally friendly, nor advanced, nor safe, as consumers, we certainly have the option not to buy it,' Yuyuan Tantian, a China Central Television-affiliated account, wrote on WeChat according to Reuters.
The post also suggests that Nvidia may have built a backdoor into its H20 that could, among other things, shut down the chip — in other words a kill switch. Rather than provide its own evidence that the H20 chip is a threat, China seems to want Nvidia to prove that it isn't one. Adding to China's worries is a bill in the Senate that could lead to tracking hardware being attached to chips bound for certain regions and organizations. China's Cyberspace Administration (CAC) brought in Nvidia execs to get details, but the WeChat post suggests that China still has doubts.

Nvidia, meanwhile, is having none of this. It responded by telling CNBC that 'cybersecurity is critically important to us. Nvidia does not have 'backdoors' in our chips that would give anyone a remote way to access or control them.'
China's concerns about the H20 are likely part of the overall trade tensions between it and the Trump administration. Tariffs (and the threat of them) played a major role in those tensions this year. Although the US has placed tariffs in place that affect a wide swath of products and regions, the H20 chip has endured a particularly public tug-of-war. The US put the brakes on H20 sales to the US earlier out of concern that the chips give China's military technological capabilities that the US has long sought to hamper.
Nvidia reportedly has an inventory as large as 700,000 H20 chips ready for sale to businesses in China and ordered more from TSMC, which manufactures the AI chips. But a report by the BBC suggests that Nvidia will pay the US 15% of its revenues from China in a remarkable deal that, in the eyes of some experts, could run afoul of the Constitution. AMD also has apparently agreed to this deal, making it that much more of a dramatic change in US policy.

Elon Musk must face lawsuit claiming he ran illegal $1 million election lottery
Elon Musk was ordered on Wednesday by a federal judge to face a lawsuit by voters accusing the world's richest person of defrauding them into signing a petition to support the U.S. Constitution for a chance to win his $1 million-a-day giveaway. U.S. District Judge Robert Pitman in Austin, Texas said Jacqueline McAferty plausibly alleged in her proposed class action that Musk and his political action committee America PAC wrongly induced her to provide personal identifying information as part of the giveaway, late in the 2024 election campaign. Lawyers for Musk and America PAC did not immediately respond to requests for comment. Musk founded America PAC to support Republican Donald Trump's successful 2024 presidential run. McAferty, an Arizona resident, said Musk and America PAC induced voters in seven battleground states to sign his petition by promising that $1 million recipients would be chosen randomly, as in a lottery, though the voters had no real chance to collect. She said voters who signed were also required to provide names, addresses, email addresses and phone numbers. In seeking a dismissal, Musk listed several "red flags" as proof he had not run an illegal lottery. He said these included statements that the $1 million recipients were "selected to earn" the money and expected to become America PAC spokespeople, defeating the idea that the payment was a "prize." But the judge cited other statements suggesting the defendants were "awarding" the $1 million, and the money could be "won." "It is plausible that plaintiff justifiably relied on those statements to believe that defendants were objectively offering her the chance to enter a random lottery--even if that is not what they subjectively intended to do," Pitman wrote. The judge was appointed to the bench by President Barack Obama in 2014. Musk had also rejected the suggestion that petition signers suffered harm by providing contact information. Pitman said an expert in political data brokerage could testify what that information was worth for voters in battleground states. The lawsuit was filed on Election Day, Nov. 5, 2024. A day earlier, a Philadelphia judge refused to end Musk's giveaway, saying that city's top prosecutor failed to show it was an illegal lottery. Musk is a Texas resident, and his electric car company Tesla TSLA.O is based in Austin. The case is McAferty v Musk et al, U.S. District Court, Western District of Texas, No. 24-01346.

Work begins in Finland on a new Canadian icebreaker for Arctic defense
HELSINKI, Finland (AP) — Dignitaries at a steel-cutting ceremony Wednesday in Finland marked the start of work on a new Canadian icebreaker to be named the Polar Max and aimed at bolstering Arctic defense. The event marked the concrete beginning of a trilateral partnership of the United States, Canada and Finland announced by the White House in July 2024 to bolster defenses in a region where Russia has been increasingly active. Russia has vastly more icebreaker ships than the U.S. and Canada at a time when climate change has made the remote but strategically important Arctic more accessible. The Icebreaker Collaboration Effort, or ICE Pact, aims to leverage Finland's advanced shipbuilding expertise and technologies to help meet U.S. and Canadian demand for new icebreakers. Canada's minister for defense procurement, Stephen Fuhr, said his country is bringing its coast guard into the military and that investing in the Arctic is important for the future. 'The North is opening up, there are many reasons to be up there,' Fuhr said. 'There's security issues, resource development.' The hull will be built at Helsinki Shipyard before being transported to Canada where it's expected to be completed in Levis, Quebec by 2030. Quebec's Economy Minister Christopher Skeete highlighted the benefits of cooperating on the building of the new icebreaker. 'It's a partnership and we have a shared responsibility for the North, so this is a unique and very opportune partnership that allows us to leverage the strengths of both our countries in terms of maritime Arctic protection,' he said. 'The North is becoming more and more accessible, there are more and more rivalries in the North, and so we have to be prepared to assert our sovereignty out there,' Skeete added. During a NATO summit in June, U.S. President Donald Trump said Finland was the 'king of icebreakers' and suggested the U.S. might be willing to buy as many as 15 of them, including the used icebreaker that Trump said might be immediately available. 'We're trying to make a good deal,' Trump said. According to a U.S. Government Accountability Office report, the U.S. hasn't built a heavy polar icebreaker in almost 50 years. The last remaining one in service is the 399-foot Coast Guard Cutter Polar Star commissioned in 1976. During a talk in February at the RAND research organization, U.S. Coast Guard Vice Admiral Peter Gautier said the agency has determined it needs eight to nine icebreakers — a mix of heavy polar security cutters and medium Arctic security cutters. Building an icebreaker can be challenging because it has to be able to withstand the brutal crashing through ice that can be as thick as 21 feet (6.4 meters) and wildly varying sea and air temperatures, the report said.

Commonwealth Bank Reverses Job Cuts Decision Over AI Chatbots
Commonwealth Bank of Australia reversed a decision to cut 45 customer service roles due to new artificial intelligence technology after pressure from the country's main financial services union. The union took CBA to the workplace relations tribunal earlier this month as the company wasn't being transparent about call volumes, according to a statement Thursday from the Finance Sector Union. The nation's largest lender had said that the voice bot reduced call volumes by 2,000 a week, when union members said volumes were in fact rising and CBA had to offer staff overtime and direct team leaders to answer calls, the union said.
