  • A New Report Finds China's Space Program Will Soon Equal That of the US
    by BeauHD on 17/09/2025 at 3:30 am

    An anonymous reader quotes a report from Ars Technica: As Jonathan Roll neared completion of a master's degree in science and technology policy at Arizona State University three years ago, he did some research into recent developments by China's ascendant space program. He came away impressed by the country's growing ambitions. Now a full-time research analyst at the university, Roll was recently asked to take a deeper dive into Chinese space plans. "I thought I had a pretty good read on this when I was finishing grad school," Roll told Ars. "That almost everything needed to be updated, or had changed three years later, was pretty scary. On all these fronts, they've made pretty significant progress. They are taking all of the cues from our Western system about what's really galvanized innovation, and they are off to the races with it." Roll is the co-author of a new report, titled "Redshift," on the acceleration of China's commercial and civil space activities and the threat these pose to similar efforts in the United States. Published on Tuesday, the report was sponsored by the US-based Commercial Space Federation, which advocates for the country's commercial space industry. It is a sobering read and comes as China not only projects to land humans on the lunar surface before the US can return, but also is advancing across several spaceflight fronts to challenge America. "The trend line is unmistakable," the report states. "China is not only racing to catch up -- it is setting pace, deregulating, and, at times, redefining what leadership looks like on and above Earth. This new space race will not be won with a single breakthrough or headline achievement, but with sustained commitment, clear-eyed vigilance, and a willingness to adapt over decades." "The key takeaway here is that there is an acceleration," said Dave Cavossa, president of the Commercial Spaceflight Federation. "The United States is still ahead today in a lot of areas in space. But the Chinese are advancing very quickly and poised to overtake us in the next five to 10 years if we don't do something." "There's other things along the lines of budget battles," Cavossa said. "We don't want to see the US government scaling back its reliance on commercial satellite communications. We don't want to see them scaling back commercial remote sensing data buys, which is what they've been doing, or at least threatening to do. We want to make sure that there's a seamless transition from the ISS to commercial LEO destinations, and then a transition away from old programs of record to commercial transportation alternatives. That's what the US government can do and Congress can do here in the next couple of years to make sure that we stay ahead." Read more of this story at Slashdot.

  • ChatGPT Will Guess Your Age and Might Require ID For Age Verification
    by BeauHD on 17/09/2025 at 12:02 am

    OpenAI is rolling out stricter safety measures for ChatGPT after lawsuits linked the chatbot to multiple suicides. "ChatGPT will now attempt to guess a user's age, and in some cases might require users to share an ID in order to verify that they are at least 18 years old," reports 404 Media. "We know this is a privacy compromise for adults but believe it is a worthy tradeoff," the company said in its announcement. "I don't expect that everyone will agree with these tradeoffs, but given the conflict it is important to explain our decisionmaking," OpenAI CEO Sam Altman said on X. From the report: OpenAI introduced parental controls to ChatGPT earlier in September, but has now introduced new, more strict and invasive security measures. In addition to attempting to guess or verify a user's age, ChatGPT will now also apply different rules to teens who are using the chatbot. "For example, ChatGPT will be trained not to do the above-mentioned flirtatious talk if asked, or engage in discussions about suicide of self-harm even in a creative writing setting," the announcement said. "And, if an under-18 user is having suicidal ideation, we will attempt to contact the users' parents and if unable, will contact the authorities in case of imminent harm." OpenAI's post explains that it is struggling to manage an inherent problem with large language models that 404 Media has tracked for several years. ChatGPT used to be a far more restricted chatbot that would refuse to engage users on a wide variety of issues the company deemed dangerous or inappropriate. Competition from other models, especially locally hosted and so-called "uncensored" models, and a political shift to the right which sees many forms of content moderation as censorship, has caused OpenAI to loosen those restrictions. "We want users to be able to use our tools in the way that they want, within very broad bounds of safety," Open AI said in its announcement. The position it seemed to have landed on given these recent stories about teen suicide, is that it wants to "'Treat our adult users like adults' is how we talk about this internally, extending freedom as far as possible without causing harm or undermining anyone else's freedom."

  • Microsoft Announces $30 Billion Investment In AI Infrastructure, Operations In UK
    by BeauHD on 16/09/2025 at 11:20 pm

    Microsoft will invest $30 billion in the U.K. through 2028 to expand AI infrastructure and operations, including building the country's largest supercomputer with 23,000 GPUs in partnership with Nscale. CNBC reports: On a call with reporters on Tuesday, Microsoft President Brad Smith said his stance on the U.K. has warmed over the years. He previously criticized the country over its attempt in 2023 to block the tech giant's $69 billion acquisition of video game developer Activision-Blizzard. The deal was cleared by the U.K.s competition regulator later that year. "I haven't always been optimistic every single day about the business climate in the U.K.," Smith said. However, he added, "I am very encouraged by the steps that the government has taken over the last few years." "Just a few years ago, this kind of investment would have been inconceivable because of the regulatory climate then and because there just wasn't the need or demand for this kind of large AI investment," Smith said. Microsoft's announcement comes as President Donald Trump embarks on a state visit to Britain where he's expected to sign a new deal with U.K. Prime Minister Keir Starmer "to unlock investment and collaboration in AI, Quantum, and Nuclear technologies," the government said in a statement late Tuesday.

  • Taliban Leader Bans Wi-Fi In an Afghan Province To 'Prevent Immorality'
    by BeauHD on 16/09/2025 at 10:00 pm

    An anonymous reader quotes a report from the Associated Press: The Taliban leader banned fibre optic internet in an Afghan province to "prevent immorality," a spokesman for the administration said Tuesday. It's the first time a ban of this kind has been imposed since the Taliban seized power in August 2021, and leaves government offices, the private sector, public institutions, and homes in northern Balkh province without Wi-Fi internet. Mobile internet remains functional, however. Haji Attaullah Zaid, a provincial government spokesman, said there was no longer cable internet access in Balkh by order of a "complete ban" from the leader Hibatullah Akhundzada. "This measure was taken to prevent immorality, and an alternative will be built within the country for necessities," Zaid told The Associated Press. He gave no further information, including why Balkh was chosen for the ban or if the shutdown would spread to other provinces. Read more of this story at Slashdot.

  • Consumer Reports Asks Microsoft To Keep Supporting Windows 10
    by BeauHD on 16/09/2025 at 9:20 pm

    Consumer Reports has urged Microsoft to keep supporting Windows 10 beyond its October 2025 cutoff, saying the move will "strand millions of consumers" who have machines incompatible with Windows 11. The Verge reports: As noted by Consumer Reports, data suggests that around 46.2 percent of people around the world still use Windows 10 as of August 2025, while around 200 to 400 million PCs can't be upgraded to Windows 11 due to missing hardware requirements. In the letter, Consumer Reports calls Microsoft "hypocritical" for urging customers to upgrade to Windows 11 to bolster cybersecurity, but then leaving Windows 10 devices susceptible to cyberattacks. It also calls out the $30 fee Microsoft charges customers for "a mere one-year extension to preserve their machine's security," as well as the free support options that force people to use Microsoft products, allowing the company to "eke out a bit of market share over competitors." Consumer Reports asks that Microsoft continue providing support for Windows 10 computers for free until more people have upgraded to Windows 11. Read more of this story at Slashdot.
