As IBM Pushes For More Automation, Its AI Simply Not Up To the Job of Replacing Staff

Thu, 2024-09-26 01:21
An anonymous reader shares a report: IBM's plan to replace thousands of roles with AI presently looks more like outsourcing jobs to India, at the expense of organizational competency. That view of Big Blue was offered to The Register after our report on the IT giant's latest layoffs, which resonated so strongly with several IBM employees that they contacted The Register with thoughts on the job cuts. Our sources have asked not to be identified to protect their ongoing relationships with Big Blue. Suffice to say they were or are employed as senior technologists in business units that span multiple locations and were privy to company communications: These are not views from the narrow entrance to a single cubicle. We're going to refer to three by the pseudonyms Alex, Blake, and Casey. "I always make this joke about IBM," said Alex. "It is: 'IBM doesn't want people to work for them.' Every six months or so they are doing rounds of [Resource Actions -- IBM-speak for layoffs] or forcing folks into impossible moves, which result in separation." That's consistent with CEO Arvind Krishna's commitment last year to replace around 7,800 jobs with AI. But our sources say Krishna's plan is on shaky ground: IBM's AI isn't up to the job of replacing people, and some of the people who could fix that have been let go. Alex observed that over the past four years, IBM management has constantly pushed for automation and the use of AI. "With AI tools writing that code for us ... why pay for senior-level staff when you can promote a youngster who doesn't really know any better at a much lower price?" he said. "Plus, once you have a seasoned programmer write code that is by law the company's IP and it is fed into an AI library, it basically learns it and the author is no longer needed." But our sources tell us that scenario has yet to be realized inside IBM.

OpenAI To Remove Non-Profit Control and Give Sam Altman Equity

Thu, 2024-09-26 00:40
OpenAI is working on a plan to restructure its core business into a for-profit benefit corporation that will no longer be controlled by its non-profit board. "Chief executive Sam Altman will also receive equity for the first time in the for-profit company, which could be worth $150 billion after the restructuring as it also tries to remove the cap on returns for investors," reports Reuters. From the report: The OpenAI non-profit will continue to exist and own a minority stake in the for-profit company, the sources said. The move could also have implications for how the company manages AI risks in a new governance structure. [...] The details of the proposed corporate structure, first reported by Reuters, highlight significant governance changes happening behind the scenes at one of the most important AI companies. The plan is still being hashed out with lawyers and shareholders and the timeline for completing the restructuring remains uncertain, the sources said. "We remain focused on building AI that benefits everyone, and we're working with our board to ensure that we're best positioned to succeed in our mission. The non-profit is core to our mission and will continue to exist," an OpenAI spokesperson said. Earlier today, OpenAI's chief technology officer Mira Murati announced her departure from the company. Her resignation follows the departures of founders Ilya Sutskever and John Schulman. Further reading: OpenAI Pitched White House On Unprecedented Data Center Buildout

Ray-Ban Smart Glasses Updated With Real-Time AI Video, Reminders, and QR Code Scanning

Thu, 2024-09-26 00:00
An anonymous reader quotes a report from TechCrunch: Meta CEO Mark Zuckerberg announced updates to the company's Ray-Ban Meta smart glasses at Meta Connect 2024 on Wednesday. [...] Meta says its smart glasses will soon have real-time AI video capabilities, meaning you can ask the Ray Ban Meta glasses questions about what you're seeing in front of you, and Meta AI will verbally answer you in real time. Currently, the Ray-Ban Meta glasses can only take a picture and describe that to you or answer questions about it, but the video upgrade should make the experience more natural, in theory at least. These multimodal features are slated to come later this year. In a demo, users could ask Ray-Ban Meta questions about a meal they were cooking, or city scenes taking place in front of them. The real-time video capabilities mean that Meta's AI should be able to process live action and respond in an audible way. This is easier said than done, however, and we'll have to see how fast and seamless the feature is in practice. We've seen demonstrations of these real-time AI video capabilities from Google and OpenAI, but Meta would be the first to launch such features in a consumer product. Zuckerberg also announced live language translation for Ray-Ban Meta. English speaking users can talk to someone speaking French, Italian, or Spanish, and their Ray-Ban Meta glasses should be able to translate what the other person is saying into their language of choice. Meta says this feature is coming later this year and will include more language later on. The Ray-Ban Meta glasses are getting reminders, which will allow people to ask Meta AI to remind them about things they look at through the smart glasses. In a demo, a user asked their Ray-Ban Meta glasses to remember a jacket they were looking at, so they could share the image with a friend later on. Meta announced that integrations with Amazon Music, Audible, and iHeart are coming to its smart glasses. This should make it easier for people to listen to music on their streaming service of choice using the glasses' built-in speakers. The Ray-Ban Meta glasses will also gain the ability to scan QR codes or phone numbers from the glasses. Users can ask the glasses to scan something, and the QR code will immediately open on the person's phone with no further action required. Zuckerberg also unveiled the company's prototype AR glasses codenamed Orion, which feature a 70-degree field of view, Micro LED projectors, and silicon carbide lenses that beam graphics directly into the wearer's eyes.

Evan Prodromou Launches The Social Web Foundation To Build Out the Fediverse

Wed, 2024-09-25 23:20
Evan Prodromou, co-author of the ActivityPub protocol, has launched The Social Web Foundation to address the challenges of the ActivityPub ecosystem and foster the growth of the Fediverse. The foundation aims to support developers, organizations, and governments through advocacy, educational materials, and infrastructure, while maintaining a decentralized approach to improving the social web. We Distribute reports: "I wish I would've started it five years ago," Evan explains in a call, "We're seeing growth of ActivityPub in the commercial sector, we want to help guide that work, especially for devs that don't know how to engage with the Fediverse, or the work that happens in private spaces. As we're seeing a lot of growth, it's important to help push that growth forward, we're really filling in the crack no other organization is doing." The foundation launches with a dedicated team of three: Evan Prodromou is the Research Director, Mallory Knodel serves as the Executive Director, and Tom Coates acts as Product Director. The trio brings a wealth of knowledge regarding protocol development, open source development, technology policy, and product development for the Web. In terms of fulfilling its goals, the organization has a few specific areas of focus: People, Policy, Protocol, and Plumbing. The SWF has deemed these areas as critical to their mission statement, and will start with these core focuses. [...] At launch, The Social Web Foundation has announced 12 partner organizations, who serve as a pool of knowledge, resources, and stakeholders. The majority of these entities are either building for the Fediverse directly, or providing infrastructure and services indirectly. Aside from Meta being an early supporter, one surprise is the inclusion of The Ford Foundation, a social justice organization dedicated to supporting next-generation solutions for the social good. At time of launch, the SWF will have access to more than 20 dedicated advisors, who will guide the organization on current problem areas their own efforts are facing, and provide insights on how to move forward and make progress. "The Fediverse is too big and too diverse for anyone to claim to speak for the Fediverse. That's not what we want to do or who we want to be," Evan says, "We may do things that people on the network disagree with, like encouraging media organizations to join the network, but what we want to do is help the mission of growing and improving the Fediverse over time."

Russia Blocks OONI Explorer, a Large Open Dataset On Internet Censorship

Wed, 2024-09-25 22:40
As of September 11th, Russia has blocked access to OONI Explorer, citing concerns over circumvention tools. This block affects Russian users' ability to access not only circumvention data but also the extensive dataset on global internet censorship that OONI provides. From a blog post: OONI Explorer is one of the largest open datasets on internet censorship around the world. We first launched this web platform back in 2016 with the goal of enabling researchers, journalists, and human rights defenders to investigate internet censorship based on empirical network measurement data that is contributed by OONI Probe users worldwide. Every day, we publish new measurements from around the world in real-time. Today, OONI Explorer hosts more than 2 billion network measurements collected from 27 thousand distinct networks in 242 countries and territories since 2012. Out of all countries, OONI Probe users in Russia contribute the second largest volume of measurements (following the U.S, where OONI Probe users contribute the most measurements out of any country). This has enabled us to study various cases of internet censorship in Russia, such as the blocking of Tor, the blocking of independent news media websites, and how internet censorship in Russia changed amid the war in Ukraine. In this report, we share OONI data on the blocking of OONI Explorer in Russia.

OpenAI Pitched White House On Unprecedented Data Center Buildout

Wed, 2024-09-25 21:20
An anonymous reader quotes a report from Bloomberg: OpenAI has pitched the Biden administration on the need for massive data centers that could each use as much power as entire cities, framing the unprecedented expansion as necessary to develop more advanced artificial intelligence models and compete with China. Following a recent meeting at the White House, which was attended by OpenAI Chief Executive Officer Sam Altman and other tech leaders, the startup shared a document with government officials outlining the economic and national security benefits of building 5-gigawatt data centers in various US states, based on an analysis the company engaged with outside experts on. To put that in context, 5 gigawatts is roughly the equivalent of five nuclear reactors, or enough to power almost 3 million homes. OpenAI said investing in these facilities would result in tens of thousands of new jobs, boost the gross domestic product and ensure the US can maintain its lead in AI development, according to the document, which was viewed by Bloomberg News. To achieve that, however, the US needs policies that support greater data center capacity, the document said. "Whatever we're talking about is not only something that's never been done, but I don't believe it's feasible as an engineer, as somebody who grew up in this," said Joe Dominguez, CEO of Constellation Energy Corp. "It's certainly not possible under a timeframe that's going to address national security and timing."

Meta Unveils AR Glasses Prototype

Wed, 2024-09-25 20:02
Meta unveiled prototype AR glasses codenamed Orion on Wednesday, featuring a 70-degree field of view, Micro LED projectors, and silicon carbide lenses that beam graphics directly into the wearer's eyes. In an interview with The Verge, CEO Mark Zuckerberg demonstrated the device's capabilities, including ingredient recognition, holographic gaming, and video calling, controlled by a neural wristband that interprets hand gestures through electromyography. Despite technological advances, Meta has shelved Orion's commercial release, citing manufacturing complexities and costs reaching $10,000 per unit, primarily due to difficulties in producing the silicon carbide lenses. The company now aims to launch a refined, more affordable version in coming years, with executives hinting at a price comparable to high-end smartphones and laptops. Zuckerberg views AR glasses as critical to Meta's future, potentially freeing the company from its reliance on smartphone platforms controlled by Apple and Google. The push into AR hardware comes as tech giants and startups intensify competition in the space, with Apple launching Vision Pro and Google partnering with Magic Leap and Samsung on headset development.

Google Complains To EU Over Microsoft Cloud Practices

Wed, 2024-09-25 19:29
Alphabet unit Google filed a complaint to the European Commission on Wednesday against what it said were Microsoft's anti-competitive practices to lock customers into Microsoft's cloud platform Azure. From a report: Google, whose biggest cloud computing rivals are Microsoft and Amazon Web Services, said Microsoft was exploiting its dominant Windows Server operating system to prevent competition. Google Cloud Vice President Amit Zavery told a briefing that Microsoft made customers pay a 400% mark-up to keep running Windows Server on rival cloud computing operators. This did not apply if they used Azure. Users of rival cloud systems would also get later and more limited security updates, Zavery said. Google pointed to a 2023 study by cloud services organization CISPE which found that European businesses and public sector bodies were paying up to 1 billion euros ($1.12 billion) per year on Microsoft licensing penalties. Microsoft in July clinched a 20-million-euro deal to settle an antitrust complaint about its cloud computing licensing practices with CISPE, averting an EU investigation. However, the settlement did not include Amazon Web Services, Google Cloud Platform and AliCloud, prompting criticism from the first two companies.

China-Linked Hackers Breach US Internet Providers in New 'Salt Typhoon' Cyberattack

Wed, 2024-09-25 18:41
Hackers linked to the Chinese government have broken into a handful of U.S. internet-service providers in recent months in pursuit of sensitive information, WSJ reported Wednesday, citing people familiar with the matter. From the report: The hacking campaign, called Salt Typhoon by investigators, hasn't previously been publicly disclosed and is the latest in a series of incursions that U.S. investigators have linked to China in recent years. The intrusion is a sign of the stealthy success Beijing's massive digital army of cyberspies has had breaking into valuable computer networks in the U.S. and around the globe. In Salt Typhoon, the actors linked to China burrowed into America's broadband networks. In this type of intrusion, bad actors aim to establish a foothold within the infrastructure of cable and broadband providers that would allow them to access data stored by telecommunications companies or launch a damaging cyberattack. Last week, U.S. officials said they had disrupted a network of more than 200,000 routers, cameras and other internet-connected consumer devices that served as an entry point into U.S. networks for a China-based hacking group called Flax Typhoon. And in January, federal officials disrupted Volt Typhoon, yet another China-linked campaign that has sought to quietly infiltrate a swath of U.S. critical infrastructure. "The cyber threat posed by the Chinese government is massive," said Christopher Wray, the Federal Bureau of Investigation's director, speaking earlier this year at a security conference in Germany. "China's hacking program is larger than that of every other major nation, combined." U.S. security officials allege that Beijing has tried and at times succeeded in burrowing deep into U.S. critical infrastructure networks ranging from water-treatment systems to airports and oil and gas pipelines. Top Biden administration officials have issued public warnings over the past year that China's actions could threaten American lives and are intended to cause societal panic. The hackers could also disrupt the U.S.'s ability to mobilize support for Taiwan in the event that Chinese leader Xi Jinping orders his military to invade the island.

Google Paid $2.7 Billion To Bring Back an AI Genius Who Quit in Frustration

Wed, 2024-09-25 18:04
At a time when tech companies are paying eye-popping sums to hire the best minds in artificial intelligence, Google's deal to rehire Noam Shazeer has left others in the dust. From a report: A co-author of a seminal research paper that kicked off the AI boom, Shazeer quit Google in 2021 to start his own company after the search giant refused to release a chatbot he developed. When that startup, Character.AI, began to flounder, his old employer swooped in. Google wrote Character a check for around $2.7 billion, according to people with knowledge of the deal. The official reason for the payment was to license Character's technology. But the deal included another component: Shazeer agreed to work for Google again. Within Google, Shazeeer's return is widely viewed as the primary reason the company agreed to pay the multibillion-dollar licensing fee. The arrangement has thrust him into the middle of a debate in Silicon Valley about whether tech giants are overspending in the race to develop cutting-edge AI, which some believe will define the future of computing.

Admins Using Windows Server Update Services Up in Arms as Microsoft Deprecates Feature

Wed, 2024-09-25 17:20
Microsoft giveth and Microsoft taketh away, as administrators using Windows Server Update Services (WSUS) will soon find out. From a report: Windows Server 2025 remains in preview, but Microsoft has been busy letting users know what is set for removal and what will be deprecated in the release. WSUS fits into the latter category -- still there for now, but no longer under active development. This is a big deal for many administrators who rely on the feature to deploy and manage the distribution of updates and features in an enterprise environment. It'll even work on a network disconnected from the internet -- download the patches to a connected computer, stick them on some removable media, import the patches to a WSUS server on the disconnected network, and away you go. A tame administrator told El Reg: "We are migrating to Intune. It's a lot more complicated than WSUS, and it takes a lot longer to get set up." "Such is progress!" he sighed. Microsoft's advice is, unsurprisingly, to migrate to cloud tools. As well as the aforementioned Intune, there is also Windows Autopatch for client update management or Azure Update Manager for server update management. And there are plenty of third-party tools out there too, such as Ansible. Microsoft's announcement has attracted comment. One user said: "Congratulations, you just made centralized automated patching subject to internal politics and budget constraints. "I survived the era of Melissa, SQL Slammer, and other things that were solved when we no longer had to choose between paid patch management or trusting admins of every server to do the right thing. For those of you that did not live through that, buckle up!"

New California Law Requires One-Click Subscription Cancellations

Wed, 2024-09-25 16:40
A new law in California will make it easier for consumers to cancel their streaming subscriptions and similar products when they enroll in automatic renewal of those services. From a report: The law, passed through Assembly Bill (AB) 2863, will require companies that offer automatic subscription renewals through one-click purchases to also offer customers a way to cancel their subscriptions through the same one-click method. California already had one of the toughest subscription cancellation laws in the country, requiring companies to offer a way to cancel a recurring subscription through the Internet if they allowed customers to sign up for a service that way. The initial law was meant to prevent companies from allowing customers to purchase a subscription through the web, while forcing them to call a hotline to cancel them. Consumer advocacy groups complained that companies would often subject customers to frustrating long wait times on the phone with the hope that they would eventually hang up without cancelling their service. While the law was good in theory, it contained at least one loophole: Companies were in compliance as long as they offered a way for customers to cancel their subscriptions online, but could make them click several links or visit several webpages with opt-in requirements before a cancellation request was processed.

Nintendo Japan Plans To Stop Repairing Its Classic Edition Consoles

Wed, 2024-09-25 16:00
An anonymous reader shares a report: Somehow, Nintendo's NES Classic Edition console is already almost eight years old, while the Super Nintendo Classic Edition is about to turn seven. That's apparently old enough for Nintendo to announce that the Japanese versions of the consoles -- the Nintendo Classic Mini Family Computer and the Nintendo Classic Mini Super Famicom -- will no longer be eligible for repair once Nintendo Japan's current stock of parts runs out. That doesn't mean that if you wake up tomorrow morning with a mini Famicom that won't boot you're out of luck. Nintendo Japan will continue to accept repairs but is warning users that it doesn't have a definitive timeline for how long that will be the case.

Microsoft Claims Its New Tool Can Correct AI Hallucinations

Wed, 2024-09-25 15:00
An anonymous reader quotes a report from TechCrunch: Microsoft today revealed Correction, a service that attempts to automatically revise AI-generated text that's factually wrong. Correction first flags text that may be erroneous -- say, a summary of a company's quarterly earnings call that possibly has misattributed quotes -- then fact-checks it by comparing the text with a source of truth (e.g. uploaded transcripts). Correction, available as part of Microsoft's Azure AI Content Safety API (in preview for now), can be used with any text-generating AI model, including Meta's Llama and OpenAI's GPT-4o. "Correction is powered by a new process of utilizing small language models and large language models to align outputs with grounding documents," a Microsoft spokesperson told TechCrunch. "We hope this new feature supports builders and users of generative AI in fields such as medicine, where application developers determine the accuracy of responses to be of significant importance." Experts caution that this tool doesn't address the root cause of hallucinations. "Microsoft's solution is a pair of cross-referencing, copy-editor-esque meta models designed to highlight and rewrite hallucinations," reports TechCrunch. "A classifier model looks for possibly incorrect, fabricated, or irrelevant snippets of AI-generated text (hallucinations). If it detects hallucinations, the classifier ropes in a second model, a language model, that tries to correct for the hallucinations in accordance with specified 'grounding documents.'" Os Keyes, a PhD candidate at the University of Washington who studies the ethical impact of emerging tech, has doubts about this. "It might reduce some problems," they said, "But it's also going to generate new ones. After all, Correction's hallucination detection library is also presumably capable of hallucinating." Mike Cook, a research fellow at Queen Mary University specializing in AI, added that the tool threatens to compound the trust and explainability issues around AI. "Microsoft, like OpenAI and Google, have created this issue where models are being relied upon in scenarios where they are frequently wrong," he said. "What Microsoft is doing now is repeating the mistake at a higher level. Let's say this takes us from 90% safety to 99% safety -- the issue was never really in that 9%. It's always going to be in the 1% of mistakes we're not yet detecting."

45 Years Ago CompuServe Connected the World Before the World Wide Web

Wed, 2024-09-25 12:00
Tony Isaac shares a report from WOSU Public Media: Silicon Valley has the reputation of being the birthplace of our hyper-connected Internet age, the hub of companies such as Apple, Google and Facebook. However, a pioneering company here in central Ohio is responsible for developing and popularizing many of the technologies we take for granted today. A listener submitted a question to WOSU's Curious Cbus series wanting to know more about the legacy of CompuServe and what it meant to go online before the Internet. That legacy was recently commemorated by the Ohio History Connection when they installed a historical marker in Upper Arlington -- near the corner of Arlington Center and Henderson roads -- where the company located its computer center and corporate building in 1973. The plaque explains that CompuServe was "the first major online information service provider," and that its subscribers were among the first to have access to email, online newspapers and magazines and the ability to share and download files. CompuServe, founded in 1969 in Ohio as a subsidiary of Golden United Life Insurance, began as a computer time-sharing service for businesses. In 1979, it launched an online service for consumers, partnering with RadioShack since they "were key in reaching early computer users." Acquired by H&R Block in 1980, CompuServe became a leader in digital innovations like email, online newspapers, and chat forums, with The Columbus Dispatch becoming the first online newspaper. "... it turned out that what was most popular is not reading reliable news sources, but just shooting the breeze with your friends or arguing with strangers over politics," said former tech journalist and early Compuserve user Dylan Tweney. Despite competing with Prodigy and AOL through the 1990s, CompuServe struggled with the rise of the internet. AOL acquired the company in 1997, but CompuServe remains a digital pioneer for fostering online communities. "For a lot of people, CompuServe was a connection to the world and their first introduction to the idea that their computer could be more than a computer," said Tweney. "It was a communications device, an information device."

X-Rays From a Nuclear Explosion Could Redirect an Asteroid

Wed, 2024-09-25 09:00
Scientists have proposed a method to deflect dangerous asteroids using nuclear explosions, not by directly blowing them up, but by detonating a bomb above the surface to create an X-ray burst that vaporizes part of the asteroid and changes its course. Experiments using the Z machine at Sandia National Laboratories simulated this process, showing that it could potentially redirect even large asteroids to prevent catastrophic impacts on Earth. Space.com reports: In a new study, the researchers employed the Z machine at Sandia National Laboratory, the most powerful laboratory source of radiation in the world. It generates powerful electric pulses, magnetic fields and X-rays to find out how materials react under high pressures and temperatures. "At present, there is only one way to generate an intense enough X-ray burst to do an experiment like this, and that's using the Z Machine," said [Nathan Moore, a physicist at Sandia National Laboratories in Albuquerque, N.M.]. The scientists used electrical pulses from the Z machine to generate powerful magnetic fields. These in turn compressed argon gas to generate plasma, the same form of matter that makes up lightning and stars. This argon plasma produced the X-ray burst the researchers needed to simulate a similar one from a nuclear explosion. "You have to concentrate a lot of power, about 80 trillion watts, into a very small space, the size of a pencil lead, and very quickly, about 100 billionths of second, to generate a hot enough argon plasma, several millions of degrees, to make a powerful enough X-ray burst to heat the asteroid material surface to tens of thousands of degrees to give it enough push," Moore said. The scientists hung up a pair of targets in a vacuum, each 0.47 inches (12 millimeters) wide -- one made of quartz, the other of fused silica. These materials are similar in composition to known asteroids. Previous attempts to study various asteroid deflection strategies all held targets fixed in place, "which wasn't very realistic," Moore said. "After all, asteroids in outer space aren't attached to anything. Besides, how would a mock asteroid accelerate realistically if it was anchored down?" To overcome this problem, the researchers devised what they called "X-ray scissors." They hung the targets up using thin metal foil just 13 microns thick, or about one-eighth the thickness of an average human hair. This foil vaporized when the X-rays hit it, freeing the targets to accelerate naturally in space. The X-ray pulses generated vapor plumes from each target and accelerated each one to about 155 mph (250 km/h), matching computational predictions. "The ability to deflect miniature asteroids in a laboratory using the Z Machine is unlike anything else you can do anywhere else on Earth," Moore said. Scaling these findings up to a 2.5-mile-wide (4 kilometer) asteroid, with a 1 megaton nuclear bomb exploding about 1.25 miles (2 km) from its surface, the researchers suggested the resulting push could help deflect dangerous asteroids away from Earth. "For reference, a 4-km [2.5-mile] asteroid is predicted to be large enough to cause global devastation and possible disruption of civilization, according to the NASA Planetary Defense Strategy and Action Plan," Moore said. Moore noted that asteroids come in a variety of compositions. "This new technique can be used to investigate the deflection response of different asteroid materials," he said. "Understanding how different asteroid materials vaporize and deflect will be critical for preparing for a planetary defense mission, should the need arise." The study has been published in the journal Nature Physics.

Car Software Patches Are Over 20% of Recalls, Study Finds

Wed, 2024-09-25 05:30
An anonymous reader quotes a report from Ars Technica: Software fixes are now responsible for more than 1 in 5 automotive recalls. That's the key finding from a decade's worth of National Highway Traffic Safety Administration recall data, according to an analysis from the law firm DeMayo Law. While that's a sign of growing inconvenience for drivers, the silver lining is that a software patch is usually a much quicker fix than something requiring hardware replacement. "Our analysis suggests we're witnessing a shift in how automotive recalls are handled. The growing number of software-related recalls, coupled with the ability to address issues remotely, could revolutionize the recall process for both manufacturers and vehicle owners," said a spokesperson for DeMayo Law. In 2014, 34 of 277 automotive recalls were software fixes. The percentage of software recalls floated around 12-13 percent (apart from a spike in 2015) before growing steadily from 2020. In 2021, 16 percent of automotive recalls (61 out of 380) were for software. In 2022, almost 22 percent of recalls were software fixes (76 out of 348), and last year topped 23 percent (82 out of 356). Leading the way was Chrysler, with 82 different software recalls since 2014. Ford (66 recalls) and Mercedes-Benz (60) are the two runner-ups. Meanwhile, Tesla ranks only eighth, with 26 software recalls since 2014, which puts it on par with Hyundai (25) and Kia (25). Electrical systems were the most common problem area, which makes sense -- this is also the second-most common hardware fix recall and would probably be the top if it were not for the massive Takata airbag recall, which has affected more than 100 million cars worldwide. The other common systems affected by recalls requiring software remedies were related to backover prevention -- whether that be reversing cameras, collision warnings, or automatic emergency braking -- airbags, powertrains, and exterior lighting. "It should be noted that not all recalls involving a software fix are to solve a software problem," notes Ars' Jonathan M. Gitlin. "Take the recent Jaguar I-Pace recall, which was triggered by battery fires caused by battery cells damaged during assembly. Jaguar's fix? A software update that sets a new, lower limit to the storage capacity of the battery pack, preventing it from fully charging to 100 percent."
