China aims to commercialize nuclear fusion technology for use in emissions-free power generation by 2050, according to the country's state-owned atomic company. From a report: China National Nuclear Corp., which runs an experimental device dubbed the 'artificial sun,' could start commercial operation of its first power generation project about five years after a demonstration phase starting around 2045, it said in a media briefing on Friday.

The Asian nation has recently stepped up its ambitions in achieving nuclear fusion, a process by which the sun and other stars generate energy and that is considered a near-infinite form of clean energy. It is notoriously difficult to carry out in a sustained and usable manner and only a handful of countries like the US, Russia and South Korea have managed to crack the basics.

NBC News reports that Utah could make history as America's first state to ban fluoride in public water systems — even though major medical associations supporting water fluoridation: If signed into law [by the governor], HB0081 would prevent any individual or political subdivision from adding fluoride "to water in or intended for public water systems..." A report published recently in JAMA Pediatrics found a statistically significant association between higher fluoride exposure and lower children's IQ scores — but the researchers did not suggest that fluoride should be removed from drinking water. According to the report's authors, most of the 74 studies they reviewed were low-quality and done in countries other than the United States, such as China, where fluoride levels tend to be much higher, the researchers noted.

An Australian study published last year found no link between early childhood exposure to fluoride and negative cognitive neurodevelopment. Researchers actually found a slightly higher IQ in kids who consistently drank fluoridated water. The levels in Australia are consistent with U.S. recommendations.

Major public health groups, including the American Academy of Pediatrics, the American Dental Association and the CDC — which says drinking fluoridated water keeps teeth strong and reduces cavities — support adding fluoride to water.
The article notes that since 2010 over 150 U.S. towns or counties have voted to keep fluoride out of public water systems or to stop adding it to their water (according to the anti-fluoride group "Fluoride Action Network"). But this week the American Dental Association (representing 159,000 members) urged Utah's governor not to become " the only state to end this preventive health practice that has been in place for over three quarters of a century."

Chinese scientists are developing a lightweight Mars drone capable of both rolling on the ground and flying using contra-rotating coaxial rotors. Space.com reports: The air-ground dual-purpose unmanned aerial vehicle (UAV) weighs only 10.6 ounces (300 grams), equivalent to the weight of an apple. The development team is at the School of Astronautics (SoA) of the Harbin Institute of Technology. Seen as showing promising potential in future Mars science work, the UAV can take off at any time, traverse obstacles, and boasts superb endurance, reports state-owned China Central Television (CCTV).

"On the ground, it mainly rolls by shifting its center of gravity," said Zhu Yimin, a Ph.D candidate at SoA. "In the air, it relies on a pair of contra-rotating coaxial rotors, controlled by a steering engine to adjust the forward direction, to control torque and force, ultimately achieving stable flight," Zhu told CCTV. The UAV work entails multiple models of air-ground dual-mode robots with different configurations, CCTV reports. These robots move by rolling close to the ground, which reduces energy consumption, and can achieve a flight endurance time of more than six times that of traditional drones of the same size.

According to Zhang Lixian, a professor within the SoA, the hope is that the aerial vehicle can show off its long endurance and observational abilities on Mars. "Our second goal is for such machines to be suitable for construction in many underground spaces and for exploring unknown underground spaces. We also need robotic means for inspection and environmental detection. We have now materialized all these functions," said Zhang. A video of the drone can be found here.

Apple is facing a class action lawsuit alleging it misled consumers by falsely claiming certain Apple Watches were carbon neutral, as the carbon offset projects it relied on did not effectively reduce greenhouse gas emissions. The Verge reports: Apple said in 2023 that "select case and band combinations" of its Apple Watch Series 9, Apple Watch Ultra 2, and Apple Watch SE would be the company's first carbon neutral devices. The suit was filed on behalf of anyone who bought those watches. It alleges that the products were not really carbon neutral because they relied on faulty offset projects that didn't actually reduce the company's greenhouse gas pollution. [...]

The company's carbon neutral claims were false, and the seven plaintiffs would not have purchased the Apple Watches or paid as much for them had they known that, the lawsuit alleges. "Apple's false advertising may lead [consumers] to choose its products over genuinely sustainable alternatives," the complaint (PDF) filed in a California federal court on Wednesday says.

Apple is standing by its assertions. "We are proud of our carbon neutral products, which are the result of industry-leading innovation in clean energy and low-carbon design," Apple spokesperson Sean Redding said in an email. Redding says the company reduced Apple Watch emissions by more than 75 percent. The company focused on cutting pollution from materials, electricity, and transportation used to make the watches, in part by getting more of its suppliers to switch to clean energy. To deal with the remaining pollution, Redding says Apple invests in "nature-based projects to remove hundreds of thousands of metric tons of carbon from the air." That's where the new lawsuit finds problems.

To offset their emissions, many companies buy carbon credits from forestry projects that represent tons of planet-heating carbon dioxide that trees and soil naturally trap. Apple primarily purchased credits from the Chyulu Hills project in Kenya and the Guinan Project in China, the suit says. It alleges that neither of the projects met a basic standard for carbon offsets, which is that they capture additional CO2 that would not otherwise have been sequestered had Apple not paid to support the project.

President Trump has directly criticized the UK government's approach to encryption, comparing recent actions to those of China. Speaking to The Spectator, Trump said he confronted UK Prime Minister Keir Starmer about the Home Office's request for "backdoor access" to encrypted iCloud data, which led Apple to remove its Advanced Data Protection feature from British services entirely.

"We told them you can't do this... That's incredible. That's something, you know, that you hear about with China," Trump said after his meeting with Starmer. The remarks come as the Trump administration has directed Treasury and Commerce officials to examine UK tech regulations, including the Online Safety Act, for potential free speech violations and discrimination against US companies.

Microsoft is pushing the Trump administration to loosen and simplify a new system that would restrict the sales of cutting-edge U.S. artificial-intelligence chips to much of the world. From a report: In a blog post that is scheduled to be released Thursday, Microsoft will call for Trump's team to ease the limits on chips that can be used in data centers for training AI models so they no longer apply to a group of U.S. allies including India, Switzerland and Israel [non-paywalled source], company officials said. Those countries are in the second tier of a three-tier system that underpins the export controls.

Microsoft says the unintended consequence of that proposed system would be that allies facing limited U.S. chip supply would turn to China to get the tech infrastructure they need. China is using the proposed rule to argue to other countries that it would be a better long-term partner for AI infrastructure than the U.S., Microsoft President Brad Smith said in an interview. "Their message is these countries can't rely on the U.S., but China is willing to provide what they need," he said. "That is not good for American business or American foreign policy."

In an interview with CNBC's Jon Fortt on Wednesday, Nvidia CEO Jensen Huang said next-gen AI will need 100 times more compute than older models as a result of new reasoning approaches that think "about how best to answer" questions step by step. From a report: "The amount of computation necessary to do that reasoning process is 100 times more than what we used to do," Huang told CNBC's Jon Fortt in an interview on Wednesday following the chipmaker's fourth-quarter earnings report. He cited models including DeepSeek's R1, OpenAI's GPT-4 and xAI's Grok 3 as models that use a reasoning process.

Huang pushed back on that idea in the interview on Wednesday, saying DeepSeek popularized reasoning models that will need more chips. "DeepSeek was fantastic," Huang said. "It was fantastic because it open sourced a reasoning model that's absolutely world class." Huang said that company's percentage of revenue in China has fallen by about half due to the export restrictions, adding that there are other competitive pressures in the country, including from Huawei.

Developers will likely search for ways around export controls through software, whether it be for a supercomputer, a personal computer, a phone or a game console, Huang said. "Ultimately, software finds a way," he said. "You ultimately make that software work on whatever system that you're targeting, and you create great software." Huang said that Nvidia's GB200, which is sold in the United States, can generate AI content 60 times faster than the versions of the company's chips that it sells to China under export controls.

Chinese AI startup DeepSeek is speeding up the release of its R2 model following the success of January's R1, which outperformed many US competitors at a fraction of the cost and triggered a $1 trillion-plus market selloff. The Hangzhou-based firm had planned a May release but now wants R2 out "as early as possible," Reuters reported Tuesday.

The upcoming model promises improved coding capabilities and reasoning in multiple languages beyond English. DeepSeek's competitive advantage stems from its parent company High-Flyer's early investment in computing power, including two supercomputing clusters acquired before U.S. export bans on advanced Nvidia chips. The second cluster, Fire-Flyer II, comprised approximately 10,000 Nvidia A100 chips. DeepSeek's cost-efficiency comes from innovative architecture choices like Mixture-of-Experts (MoE) and multihead latent attention (MLA).

According to Bernstein analysts, DeepSeek's pricing was 20-40 times cheaper than OpenAI's equivalent models. The competitive pressure has already forced OpenAI to cut prices and release a scaled-down model, while Google's Gemini has introduced discounted access tiers.

An anonymous reader quotes a report from TorrentFreak: In France, rightsholders have taken legal action to compel large VPN providers to support their pirate site blocking program. The aim is to reinforce existing blocking measures, but VPN providers see this as a dangerous move, leading to potential security issues and overblocking. As a result, some are considering leaving France altogether if push comes to shove. [...] Earlier this month, sports rightsholders Canal+ and LFP requested blocking injunctions that would require popular VPNs to start blocking pirate sites and services. The full requests are not public, but the details available show that Cyberghost, ExpressVPN, NordVPN, ProtonVPN, and Surfshark are listed as respondents. [...]

The blocking request has yet to be approved and several of the targeted VPN providers have reserved detailed commentary, for now. That said, the VPN Trust Initiative (VTI), which includes ExpressVPN, NordVPN and Surfshark as members, has been vocal in its opposition. VTI is part of the i2Coalition and while it doesn't speak directly for any of the members, the coalition's Executive Director Christian Dawson has been in regular discussions with VPN providers. From this, it became clear that VPN providers face difficult decisions. If VPN providers are ordered to block pirate sites, some are considering whether to follow in the footsteps of Cisco, which discontinued its OpenDNS service in the country, to avoid meddling with its DNS resolver.

Speaking with TorrentFreak, VTI's Dawson says that VPNs have previously left markets like India and Pakistan in response to restrictive requirements. This typically happens when privacy or security principles are at risk, or if the technical implementation of blocking measures is infeasible. VTI does not rule out that some members may choose to exit France for similar reasons, if required to comply with blocking measures. "We've seen this before in markets like India and Pakistan, where regulatory requirements forced some VPN services to withdraw rather than compromise on encryption standards or log-keeping policies," Dawson says. "France's potential move to force VPN providers to block content could put companies in a similar position -- where they either comply with measures that contradict their purpose or leave the market altogether." "This case in France is part of a broader global trend of regulatory overreach, where governments attempt to control encrypted services under the guise of content regulation. We've already seen how China, Russia, Myanmar, and Iran have imposed VPN restrictions as part of broader censorship efforts."

"The best path forward is for policymakers to focus on targeted enforcement measures that don't undermine Internet security or create a precedent for global Internet fragmentation," concludes Dawson. "As seen in other cases, blanket blocking measures do not effectively combat piracy but instead create far-reaching consequences that disrupt the open Internet."

Major corporations are reshaping their workforces around AI with Salesforce announcing it will not hire software engineers in 2025 and other companies laying off thousands while shifting focus to AI-specific roles. Duolingo has laid off thousands after implementing ChatGPT-4, UPS cut 4,000 jobs in its largest layoff in 116 years, and IBM paused hiring for back-office and HR positions that AI can now handle.

Amazon is redirecting staff from Alexa to AI areas, while Intuit is laying off 10% of its non-AI workforce. Cisco plans to cut 7% of employees in its second round of job cuts this year as it prioritizes AI and cybersecurity. Salesforce reports its AI platform is boosting software engineering productivity by 30%. SAP is restructuring 8,000 positions to focus on AI-driven business areas. The trend extends globally, with Microsoft relocating thousands during an "exodus" from China, while entry-level jobs on Wall Street are becoming obsolete.

A study found that 3 out of 10 companies replaced workers with AI last year, with over one-third of firms using AI likely to automate more roles in 2025. Job listings at large privately-held AI companies have dropped 14.2% over six months, JP Morgan wrote in a note seen by Slashdot. The transformation is creating new opportunities, with rising demand for AI skills in job postings. A survey of more than 1,200 users found nearly two-thirds of young professionals use AI tools at work, with 93% not worried about job threats, as business leaders view Generation Z's digital skills as beneficial for leveraging AI.

The Washington Post looks at a new kind of battery that "could make American EVs cheaper and safer, experts say." If you bought an EV with a lithium iron phosphate (LFP) battery, you could expect lower car payments, less fire risk and more years of use out of your car — but you wouldn't be able to go as far on a single charge as you could with the nickel manganese cobalt (NMC) batteries commonly found in American and European electric cars. That trade-off has made LFP batteries the go-to choice for standard-range EVs in China, helping to make electric cars more affordable and limit pollution. Now, American companies are starting to build their own LFP batteries to catch up to their Chinese rivals... But there are plenty of barriers for U.S. companies that want to adopt a technology dominated by Chinese firms. Tariffs and tax credit restrictions have made it too expensive for most American automakers to import LFP batteries from China, and national security concerns have made it hard for American companies to partner with Chinese battery makers to build factories in the United States...

Although American scientists invented LFP batteries in 1997, U.S. automakers didn't invest in the technology. Instead, they bet on NMC batteries because they have longer range, a big concern for American EV buyers. "Everyone in the West thought LFP was a nonstarter five or six years ago," said Adrian Yao, who founded STEER, a technology research group within Stanford University. "We really did have a myopic focus on" range, he added. That left the door open for Chinese companies to perfect LFP batteries, which have a few advantages. Instead of pricey nickel and cobalt, they use iron, which makes them 20 percent cheaper than NMC batteries, according to the International Energy Agency. While NMC batteries can be recharged up to about 1,000 times before they go kaput — which is enough to put 200,000 miles on most EVs — LFP batteries can last two or three times as long, according to Moura. Plus, LFP batteries' chemistry makes them less likely to catch fire and easier to extinguish. An NMC battery, on the other hand, is so flammable that "you could put it underwater or in space, and it'll keep burning because the oxygen it needs to keep the flame going is embedded within itself," Moura said.

That safety advantage is key, because Chinese firms figured out they could pack LFP cells closer together inside a battery pack without risking a fire. That meant they could cram more energy into LFP batteries and nearly catch up to the range of NMC batteries. Last year, the Chinese battery giant CATL made the first LFP battery with more than 600 miles of range. Since LFP batteries are made from common materials and last longer, they also have a smaller environmental footprint than NMC batteries.
Ford used LFP batteries in its Mach-E sedan (2023) and F-150 Lightning pickup trucks (2024), according to the article, "while Rivian began using them in the basic trims of its R1S SUV and R1T pickup truck this year... American LFP factories are slated to open this year in St. Louis and next year in Arizona." And an environmental engineering professor at the University of California at Berkeley predicts LFP battery factories in the U.S. will "grow quite rapidly over the next five to 10 years."

OpenAI has banned a group of Chinese accounts using ChatGPT to develop an AI-powered social media surveillance tool. Engadget reports: The campaign, which OpenAI calls Peer Review, saw the group prompt ChatGPT to generate sales pitches for a program those documents suggest was designed to monitor anti-Chinese sentiment on X, Facebook, YouTube, Instagram and other platforms. The operation appears to have been particularly interested in spotting calls for protests against human rights violations in China, with the intent of sharing those insights with the country's authorities.

"This network consisted of ChatGPT accounts that operated in a time pattern consistent with mainland Chinese business hours, prompted our models in Chinese, and used our tools with a volume and variety consistent with manual prompting, rather than automation," said OpenAI. "The operators used our models to proofread claims that their insights had been sent to Chinese embassies abroad, and to intelligence agents monitoring protests in countries including the United States, Germany and the United Kingdom."

According to Ben Nimmo, a principal investigator with OpenAI, this was the first time the company had uncovered an AI tool of this kind. "Threat actors sometimes give us a glimpse of what they are doing in other parts of the internet because of the way they use our AI models," Nimmo told The New York Times. Much of the code for the surveillance tool appears to have been based on an open-source version of one of Meta's Llama models. The group also appears to have used ChatGPT to generate an end-of-year performance review where it claims to have written phishing emails on behalf of clients in China.

Mirnotoriety shares a report from The Register: The operators of Ghost ransomware continue to claim victims and score payments, but keeping the crooks at bay is possible by patching known vulnerabilities and some basic infosec actions, according to a joint advisory issued Wednesday by the FBI and US Cybersecurity and Infrastructure Security Agency. The Feds warned orgs to beware of this spectral menace, which is known to have infected critical infrastructure and entities in every sector of a typical economy, and which has been observed scoring ransoms as recently as January. It is said to have racked up victims in more than 70 countries, including some in its China homeland.

Ghost first appeared in 2021, and according to the Feds, the gang will "rotate their ransomware executable payloads, switch file extensions for encrypted files, modify ransom note text, and use numerous ransom email addresses, which has led to variable attribution of this group over time." The Chinese group has therefore been identified as Ghost, Cring, Crypt3r, Phantom, Strike, Hello, Wickrme, HsHarada, and Rapture over time. The group's favored tactics, however, remain consistent: It targets unpatched systems to exploit known vulnerabilities that allow it to infect targets. [...]

Malaysia is aggressively expanding its data center capacity, positioning itself as Southeast Asia's fastest-growing market with planned investments exceeding $31 billion in the first 10 months of 2024, triple the amount from 2023.

The country's southern Johor province is set to host at least 1.6 gigawatts of data center capacity, up from nearly zero in 2019. Twenty-two mostly foreign data centers already occupy 21 hectares, with more under construction. The push comes as neighboring Singapore paused new data center construction in 2019 due to resource constraints.

Some experts are warning the expansion could strain Malaysia's power and water resources, with data center power demand potentially reaching 5 gigawatts by 2035 - more than half the country's current renewable capacity. The facilities, operated by companies including Microsoft, Equinix and China's GDS Holdings, primarily service East Asia, China and Europe rather than domestic users.

"[O]ur intrepid China reporter, Caiwei Chen, has identified a new trend unfolding within China's tech scene: Companies that were dominant in electric vehicles are betting big on translating that success into developing humanoid robots," writes MIT Technology Review's James O'Donnell. "I spoke with her about what she found out and what it might mean for Trump's policies and the rest of the globe..." An anonymous reader quotes an excerpt from the report: Your story looks at electric-vehicle makers in China that are starting to work on humanoid robots, but I want to ask about a crazy stat. In China, 53% of vehicles sold are either electric or hybrid, compared with 8% in the US. What explains that?

Price is a huge factor -- there are countless EV brands competing at different price points, making them both affordable and high-quality. Government incentives also play a big role. In Beijing, for example, trading in an old car for an EV gets you 10,000 RMB (about $1,500), and that subsidy was recently doubled. Plus, finding public charging and battery-swapping infrastructure is much less of a hassle than in the US.

You open your story noting that China's recent New Year Gala, watched by billions of people, featured a cast of humanoid robots, dancing and twirling handkerchiefs. We've covered how sometimes humanoid videos can be misleading. What did you think?

I would say I was relatively impressed -- the robots showed good agility and synchronization with the music, though their movements were simpler than human dancers'. The one trick that is supposed to impress the most is the part where they twirl the handkerchief with one finger, toss it into the air, and then catch it perfectly. This is the signature of the Yangko dance, and having performed it once as a child, I can attest to how difficult the trick is even for a human! There was some skepticism on the Chinese internet about how this was achieved and whether they used additional reinforcement like a magnet or a string to secure the handkerchief, and after watching the clip too many times, I tend to agree.

President Trump has already imposed tariffs on China and is planning even more. What could the implications be for China's humanoid sector?

Unitree's H1 and G1 models are already available for purchase and were showcased at CES this year. Large-scale US deployment isn't happening yet, but China's lower production costs make these robots highly competitive. Given that 65% of the humanoid supply chain is in China, I wouldn't be surprised if robotics becomes the next target in the US-China tech war.

In the US, humanoid robots are getting lots of investment, but there are plenty of skeptics who say they're too clunky, finicky, and expensive to serve much use in factory settings. Are attitudes different in China?

Skepticism exists in China too, but I think there's more confidence in deployment, especially in factories. With an aging population and a labor shortage on the horizon, there's also growing interest in medical and caregiving applications for humanoid robots.

DeepSeek revived the conversation about chips and the way the US seeks to control where the best chips end up. How do the chip wars affect humanoid-robot development in China?

Training humanoid robots currently doesn't demand as much computing power as training large language models, since there isn't enough physical movement data to feed into models at scale. But as robots improve, they'll need high-performance chips, and US sanctions will be a limiting factor. Chinese chipmakers are trying to catch up, but it's a challenge.

SCMP: Chinese scientists have developed a revolutionary repair technology that could make lithium-ion batteries last over six times longer. Announcing their discovery in the journal Nature on Wednesday, the researchers said this low-cost, eco-friendly technology could soon be ready to enter the market.

The batteries are key for many modern technologies, from smartphones to electric vehicles. However, as these batteries age, they often become less efficient -- a process that cold weather accelerates. The researchers said they could counter this problem with the "injection" of a special solution to rejuvenate "sick" batteries. At present, lithium-ion batteries rely on sophisticated materials used to generate lithium ions -- whose movement through electrolyte is key to their performance -- and then protect them to ensure a decent lifespan.

Typically these lithium ions move from the positive terminal to the negative when the battery is charging, a process which is then reversed when it is generating power. The battery is considered to have expired when the supply of lithium ions runs low -- for example some electric car batteries have a lifespan of around 1,500 charge cycles -- but other components in the battery still remain in good working order after this happens. This insight prompted the two lead researchers, Gao Yue and Peng Huisheng from Fudan University's macromolecular science department, to see if they could revive a battery by replenishing the supply of active lithium ions.

A new family of superconductors is exciting physicists. Compounds containing nickel have been shown to carry electricity without resistance at the relatively high temperature of 45 kelvin (-228C) -- and without being squeezed under pressure. Nature: Physicists at the Southern University of Science and Technology (Sustech) in Shenzhen, China, observed the major hallmarks of superconductivity in a thin film of crystals of nickel oxide, which they grew in the laboratory. They published their work in Nature on 17 February. "There's a huge hope that we could eventually raise the critical temperature and make [such materials] more useful for applications," says Dafeng Li, a physicist at the City University of Hong Kong.

Nickelates now join two groups of ceramics -- copper-based cuprates and iron-based pnictides -- as 'unconventional superconductors' that operate at room pressure and temperatures as high as 150K (-123C). This new data point could help physicists to finally explain how high-temperature superconductors work, and ultimately to design materials that operate under ambient conditions. This would make technologies, such as magnetic resonance imaging, radically cheaper and more efficient.

How unconventional superconductors operate at warmer temperatures remains largely a mystery, whereas the mechanism behind how some metals can carry electricity without resistance at colder temperatures, or extreme pressures, has been understood since 1957. The ability of the Sustech researchers to precisely engineer the material's properties is huge boon in trying to use nickelates to unravel the theory behind unconventional superconductivity, says Lilia Boeri, a physicist at the Sapienza University of Rome. "The idea that you have a system that you can sort of tune experimentally, is something quite exciting."

Acer will raise laptop prices in the United States by 10% next month due to Trump administration tariffs on Chinese imports, CEO Jason Chen said. "We will have to adjust the end user price to reflect the tariff," Chen said. "We think 10 percent probably will be the default price increase because of the import tax."

The Taiwan-based company, the fifth-largest computer seller in the U.S. market behind HP, Dell, Lenovo and Apple, could add hundreds of dollars to its high-end laptops that cost up to $3,700. Chen said Acer is exploring manufacturing options outside China, including possible U.S. production. The company has already moved desktop computer assembly out of China following earlier 25% tariffs during Trump's first term. The 10% tariff imposed this month affects nearly 80% of U.S. laptop imports from China.

Today Seoul's Personal Information Protection Commission "said DeepSeek would no longer be available for download until a review of its personal data collection practices was carried out," reports AFP. A number of countries have questioned DeepSeek's storage of user data, which the firm says is collected in "secure servers located in the People's Republic of China"... This month, a slew of South Korean government ministries and police said they blocked access to DeepSeek on their computers. Italy has also launched an investigation into DeepSeek's R1 model and blocked it from processing Italian users' data. Australia has banned DeepSeek from all government devices on the advice of security agencies. US lawmakers have also proposed a bill to ban DeepSeek from being used on government devices over concerns about user data security.
More details from the Associated Press: The South Korean privacy commission, which began reviewing DeepSeek's services last month, found that the company lacked transparency about third-party data transfers and potentially collected excessive personal information, said Nam Seok [director of the South Korean commission's investigation division]... A recent analysis by Wiseapp Retail found that DeepSeek was used by about 1.2 million smartphone users in South Korea during the fourth week of January, emerging as the second-most-popular AI model behind ChatGPT.

Long-time Slashdot reader shanen has been testing AI clients. (They report that China's DeepSeek "turned out to be extremely good at explaining why I should not trust it. Every computer security problem I ever thought of or heard about and some more besides.")

Then they wondered if there's also government censorship: It's like the accountant who gets asked what 2 plus 2 is. After locking the doors and shading all the windows, the accountant whispers in your ear: "What do you want it to be...?" So let me start with some questions about DeepSeek in particular. Have you run it locally and compared the responses with the website's responses? My hypothesis is that your mileage should differ...

It's well established that DeepSeek doesn't want to talk about many "political" topics. Is that based on a distorted model of the world? Or is the censorship implemented in the query interface after the model was trained? My hypothesis is that it must have been trained with lots of data because the cost of removing all of the bad stuff would have been prohibitive... Unless perhaps another AI filtered the data first?
But their real question is: what would it take to trust an AI? "Trust" can mean different things, including data-collection policies. ("I bet most of you trust Amazon and Amazon's secret AIs more than you should..." shanen suggests.) Can you use an AI system without worrying about its data-retention policies?

And they also ask how many Slashdot readers have read Ken Thompson's "Reflections on Trusting Trust", which raises the question of whether you can ever trust code you didn't create yourself. So is there any way an AI system can assure you its answers are accurate and trustworthy, and that it's safe to use? Share your own thoughts and experiences in the comments.

What would it take for you to trust an AI?
