The dream of quantum computers has been hampered by the challenge of error correction, writes the Harvard Gazette, since qubits "are inherently susceptible to slipping out of their quantum states and losing their encoded information." But in a newly-published paper, a research team "combined various methods to create complex circuits with dozens of error correction layers" that "suppresses errors below a critical threshold — the point where adding qubits further reduces errors rather than increasing them." "For the first time, we combined all essential elements for a scalable, error-corrected quantum computation in an integrated architecture," said Mikhail Lukin, co-director of the Quantum Science and Engineering Initiative, Joshua and Beth Friedman University Professor, and senior author of the new paper. "These experiments — by several measures the most advanced that have been done on any quantum platform to date — create the scientific foundation for practical large-scale quantum computation..." "There are still a lot of technical challenges remaining to get to very large-scale computer with millions of qubits, but this is the first time we have an architecture that is conceptually scalable," said lead author Dolev Bluvstein, Ph.D. '25, who did the research during his graduate studies at Harvard and is now an assistant professor at Caltech. "It's going to take a lot of effort and technical development, but it's becoming clear that we can build fault-tolerant quantum computers...." Hartmut Neven, vice president of engineering at the Google Quantum AI team, said the new paper came amid an "incredibly exciting" race between qubit platforms. "This work represents a significant advance toward our shared goal of building a large-scale, useful quantum computer," he said... With recent advances, Lukin believes the core elements for building quantum computers are falling into place. "This big dream that many of us had for several decades, for the first time, is really in direct sight," he said. "In theory, a system of 300 quantum bits can store more information than the number of particles in the known universe..." the article points out. "The new paper represents an important advance in a three-decade pursuit of quantum error correction." Thanks to long-time Slashdot reader schwit1 for sharing the article.

A new "cold war" between America and China is "pushing leaders to sideline concerns about the dangers of powerful AI models," reports the Wall Street Journal, "including the spread of disinformation and other harmful content, and the development of superintelligent AI systems misaligned with human values..." "Both countries are driven as much by fear as by hope of progress. " In Washington and Silicon Valley, warnings abound that China's "authoritarian AI," left unchecked, will erode American tech supremacy. Beijing is gripped by the conviction that a failure to keep pace in AI will make it easier for the U.S. to cut short China's resurgence as a global power. Both countries believe market share for their companies across the world is up for grabs — and with it, the potential to influence large swaths of the global population. The U.S. still has a clear lead, producing the most powerful AI models. China can't match it in advanced chips and has no answer for the financial firepower of private American investors, who funded AI startups to the tune of $104 billion in the first half of 2025, and are gearing up for more. But it has a massive population of capable engineers, lower costs and a state-led development model that often moves faster than the U.S., all of which Beijing is working to harness to tip the contest in its direction. A new "whole of society" campaign looks to accelerate the construction of computing clusters in areas like Inner Mongolia, where vast solar and wind farms provide plentiful cheap energy, and connect hundreds of data centers to create a shared compute pool — some describe it as a "national cloud" — by 2028. China is also funneling hundreds of billions of dollars into its power grid to support AI training and adoption... "Our lead is probably in the 'months but not years' realm," said Chris McGuire, who helped design U.S. export controls on AI chips while serving on the National Security Council under the Biden administration. Chinese AI models currently rank at or near the top in every task from coding to video generation, with the exception of search, according to Chatbot Arena, a popular crowdsourced ranking platform. China's manufacturing sector, meanwhile, is rocketing past the U.S. in bringing AI into the physical world through robotaxis, autonomous drones and humanoid robots. Given China's progress, McGuire said, the U.S. is "very lucky" to have its advantage in chips... If AI surpasses human intelligence and acquires the ability to improve itself, it could confer unshakable scientific, economic and military superiority on the country that controls it. Short of that, AI's ability to automate tedious tasks and process vast amounts of data quickly promises to supercharge everything from cancer diagnoses to missile defense. With so much at stake, hacking and cyber espionage are likely to get worse, as AI gives hackers more powerful tools, while increasing incentives for state-backed groups to try to steal AI-related intellectual property. As distrust grows, Washington and Beijing will also find it hard, if not impossible, to cooperate in areas like preventing extremist groups from using AI in destructive ways, such as building bioweapons. "The costs of the AI Cold War are already high and will go much higher," said Paul Triolo, a former U.S. government analyst and current technology policy lead at business consulting firm DGA-Albright Stonebridge Group. "A U.S.-China AI arms race becomes a self-fulfilling prophecy, with neither side able to trust that the other would observe any restrictions on advanced AI capability development...." The article includes an interesting observation from Helen Toner, director of strategy for Georgetown's Center for Security and Emerging Technology and a former OpenAI board member. Toner points out "We don't actually know" if boosting computing power with better chips will continue producing more-powerful AI models. So "If performance plateaus," the Journal writes, "despite all the spending by OpenAI and others — a growing concern in Silicon Valley — China has a chance to compete."

"Media headlines suggesting some slowdown in EV sales are simply incorrect," writes the site Electrek, "and leave out the bigger picture that gas car sales actually are dropping..." Over the course of the last two years or so, sales of battery electric vehicles, while continuing to grow, have posted lower year-over-year percentage growth rates than they had in years prior. EV sales used to grow at 50%+ per year, but for the last couple years, they have grown closer to ~25% per year. This alone is not particularly remarkable — it is inevitable that any growing product or category will show slower percentage growth rates as sales rise, particularly one that has been growing at such a fast rate for so long. In some recent years, we had even seen year-over-year doublings in EV market share (though one of those was 2020->2021, which was anomalous). To expect improvement at that level perpetually would be close to impossible — after 3 years of doubling market share from 2023's 18% number, EVs would account for more than 100% of the global automotive market, which cannot happen... We have seen a global EV sales growth rate of 23% in the first 10 months of this year, according to a report just released by Rho Motion (recently acquired by Benchmark Mineral Intelligence). That includes a +32% bump in Europe, +22% bump in China, +4% in North America, and a big +48% bump in the "rest of the world." Notably, this 23% global growth rate is higher than last year's YTD growth rate, which was 22% at this time... In covering these trends, some journalists have attempted to use the less-wrong phrase "slower growth," showing that EV sales are still growing, but at a lower percentage change than previously seen. But for the first ten months of this year, that isn't true — EV sales are up more in 2025 than in 2024 by a percentage basis. They are also up in raw sales numbers — in 2024, EV sales grew by a larger number than in 2023. And the same is true so far in 2025. Going back to 2023, 10.7 million EVs were sold globally in the first 10 months. Then in 2024, 13.3 million were sold, a difference of 2.6 million. And so far in 2025, 16.5 million EVs have sold, a difference of 3.2 million. Not only are the numbers getting bigger, but the growth in unit sales is getting bigger as well. Even in America, the EV market "has increased so far this year, with 11.7% US EV sales growth YTD." In terms of US hybrid sales, much has been made of customers "shifting from EVs to hybrids," which is also not the case. Conventional gas-hybrid sales are indeed up and plug-in hybrids, which have grown more slowly than gas-hybrids/BEVs, have also shown some growth lately. But gas-hybrid sales have not come at the cost of EV sales, rather at the cost of gas-only car sales. Because that's just the thing: the number of gas-only vehicles being sold worldwide is a number that actually is falling. That number continues to go down year over year. Sales of new gas-powered cars are down by about a quarter from their peak in 2017, and show no signs of recovering... And yet, somehow, virtually every headline you read is about the "EV sales slump," rather than the "gas-car sales slump." The one you keep hearing about isn't happening, but the one you rarely hear about is happening... No matter what region of the world you're in, EV sales were up in the first 10 months of this year.

From the personal blog of interface expert Bruce Ediger: Early in March 2025, I noticed that a web crawler with a user agent string of meta-externalagent/1.1 (+https://developers.facebook.com/docs/sharing/webmasters/crawler) was hitting my blog's machine at an unreasonable rate. I followed the URL and discovered this is what Meta uses to gather premium, human-generated content to train its LLMs. I found the rate of requests to be annoying. I already have a PHP program that creates the illusion of an infinite website. I decided to answer any HTTP request that had "meta-externalagent" in its user agent string with the contents of a bork.php generated file... This worked brilliantly. Meta ramped up to requesting 270,000 URLs on May 30 and 31, 2025... After about 3 months, I got scared that Meta's insatiable consumption of Super Great Pages about condiments, underwear and circa 2010 C-List celebs would start costing me money. So I switched to giving "meta-externalagent" a 404 status code. I decided to see how long it would take one of the highest valued companies in the world to decide to go away. The answer is 5 months.

An anonymous reader shared this post from the gaming news site Aftermath: Concord, Sony Interactive Entertainment and Firewalk Studios' Overwatch-like shooter, was live for just two weeks before it was pulled offline. Though Concord certainly had some dedicated players, it didn't have many — which is why it may be surprising to hear that a group of players are reverse-engineering the game and its servers to bring it back to life. Publisher Sony removed Concord from stores and digital marketplaces, automatically refunded some, and, later, shut down Firewalk Studios. Two hundred or so people were laid off, and any hopes of Concord's return were dashed. Poor sales — estimated to be under 25,000 copies sold — and low player numbers marred the release. Firewalk Studios' game director Ryan Ellis said in a blog post that pieces of the game "resonated with players," but "other aspects of the game and [Concord's] initial launch didn't land the way [Firewalk Studios] intended." Concord wasn't a bad game, but it just didn't generate enough interest with enough players. Now, a group of three hobbyist reverse-engineers, who go by real, Red, and gwog online, are trying to make it playable again... "Sometimes there's enough of the server left in the game, that we can 'activate' that code and make the game believe it's a server," Red said. "We do pretty much always need to fill in the gaps though..." Concord used an anti-tamper software to keep people from cheating, which also creates a problem for people reverse engineering. It's "nearly impossible" to crack, Red said, so the group didn't — they found an exploit to "forcefully decrypt the game's code" to "restore the game and start working on servers...." It's not open to the public, but people can sign up for future tests. Even former Firewalk Studios employees have joined the server. They're excited to see Concord come back to life, too, the developers said. "Friday morning, a video of the playtest was posted to the Concord Reddit page," according to the article. (Though ironically by Friday night YouTube had had removed the video "due to a copyright claim by MarkScan Enforcement."

Long-time Slashdot reader schwit1 shares a Substack post by economist/entrepreneur Skander Garroum: You know that feeling when you're waiting for the cable guy, and they said 'between 8am and 6pm, and you waste your entire day, and they never show up? Now imagine that, except the cable guy is 'electricity,' the day is '50 years,' and you're one of 600 million people. At some point, you stop waiting and figure it out yourself. What's happening across Sub-Saharan Africa right now is the most ambitious infrastructure project in human history, except it's not being built by governments or utilities or World Bank consortiums. It's being built by startups selling solar panels to farmers on payment plans. And it's working. Over 30 million solar products sold in 2024. 400,000 new solar installations every month across Africa. 50% market share captured by companies that didn't exist 15 years ago. Carbon credits subsidizing the cost. IoT chips in every device. 90%+ repayment rates on loans to people earning $2/day. And if you understand what's happening in Africa, you understand the template for how infrastructure will get built everywhere else for the next 50 years.
