General Motors' Cruise robotaxi unit announced today that it will lay off 900 employees, or 24% of its workforce. The news follows the departure of nine executives amid an ongoing safety investigation following an inccident in which a pedestrian was dragged by one of the company's self-driving cars. CNBC reports: The company had 3,800 employees before Thursday's cuts, which also follow a round of contractor layoffs at Cruise last month. Affected employees will receive paychecks until Feb. 12 and at least an additional eight weeks of pay, plus severance based on tenure. A Cruise representative also told CNBC that the company's goal is now to work on a fully driverless L4 service, as well as relaunching ride-hailing in one city to start. In a statement, a Cruise spokesperson said, "We shared the difficult news that we are reducing our workforce, primarily in commercial operations and related corporate functions. These changes reflect our decision to focus on more deliberate commercialization plans with safety as our north star. We are supporting impacted Cruisers with strong severance and benefits packages and are grateful to the departing employees who played important roles in building Cruise and supporting our mission."

GM added, "GM supports the difficult employment decisions made by Cruise as it reflects their more deliberate path forward, with safety as the north star. We are confident in the team and committed to supporting Cruise as they set the company up for long-term success with a focus on trust, accountability and transparency."

The Information: In the future, [Google] plans to use Gemini across nearly its entire line of products, from its search engine to its productivity applications and an AI assistant called Pixie that will be exclusive to its Pixel devices, two people familiar with the matter said. [...] The rollout of Pixie, an AI assistant exclusively for Pixel devices, could boost Google's hardware business at a time when tech companies are racing to integrate their hardware with new AI capabilities. Pixie will use the information on a customer's phone -- including data from Google products like Maps and Gmail -- to evolve into a far more personalized version of the Google Assistant, according to one of the people with knowledge of the project. The feature could launch as soon as next year with the Pixel 9 and the 9 Pro, this person said.

Google Maps will soon give you the option to store your location data on your device instead of in the cloud. Android Police reports: In the coming year, Google is planning to switch things up by defaulting to saving your Timeline directly on your device instead of the cloud. You'll also have the option to wipe out bits or the whole information dossier whenever you want and disable location history completely. When you're jumping ship to a new device and want to keep your data close, you always have the option to back it up in the cloud. Google assures you that it'll lock it up with encryption.

Another significant update is the shorter default amount of time before your location history is auto-deleted. Soon, when you turn on location history, the default auto-delete time shrinks to three months. In the past, it used to hang around for 18 months by default. If you're the sentimental type, you can extend the Timeline's lifespan or turn off the auto-delete option. Google Maps has another nifty trick up its sleeve: soon, you can erase all traces of your trips with just a few taps. Say you've got a favorite hangout spot and you want to keep it to yourself. You can wipe the slate clean right from the app, whether it's searches, directions, visits, or shares. This handy feature is making its debut on Maps for Android and iOS in the next few weeks.

Finally, you will soon be able to click on the blue dot on the map to view your Location History and Timeline at a glance. It allows you to tweak what you share and store on Maps, all without having to dive into the settings. Currently, the blue dot only gives you some neat shortcuts for parking saves and location sharing.

According to Reuters, General Motors' Cruise robotaxi unit dismissed nine executives amid an ongoing safety investigation, which the company confirmed included Chief Operating Officer Gil West. The company conducted a full safety review following an incident in San Francisco where a pedestrian was struck and dragged by one of its cars. GM already halted service nationwide and removed its cars from public roads. Reuters reports: CEO Kyle Vogt and co-founder Dan Kan both resigned in recent weeks and Cruise is preparing for a round of layoffs this month. "Following an initial analysis of the October 2 incident and Cruise's response to it, nine individuals departed Cruise," according to the memo. "We are committed to full transparency and are focused on rebuilding trust and operating with the highest standards when it comes to safety, integrity, and accountability," the memo said. "As a result, we believe that new leadership is necessary to achieve these goals."

The Cruise spokesperson confirmed that among those dismissed was also Chief Legal and Policy Officer Jeff Bleich and Senior Vice President of Government Affairs David Estrada. Cruise's troubles are also a setback for an industry dependent on public trust and the cooperation of regulators. The unit had in recent months touted ambitious plans to expand to more cities, offering fully autonomous taxi rides. The investigation, led by law firm Quinn Emmanuel, is expected to last until January, GM has said. "The personnel decisions made today are a necessary step for Cruise to move forward as it focuses on accountability, trust and transparency," GM said in a statement.

Earlier this year, General Motors announced plans to phase out Apple CarPlay and Android Auto, shifting instead to built-in infotainment systems developed with Google. Now, the company has explained why it made that decision to MotorTrend: Tim Babbitt, GM's head of product for infotainment, gave MT a better explanation at a press event for the new Chevrolet Blazer EV, the flagship vehicle in the no CarPlay or Android Auto strategy. According to him, there's an important factor that didn't make it into the fact sheet: safety. Specifically, he cited driver distraction caused by cell phone usage behind the wheel. According to Babbitt, CarPlay and Android Auto have stability issues that manifest themselves as bad connections, poor rendering, slow responses, and dropped connections. And when CarPlay and Android Auto have issues, drivers pick up their phones again, taking their eyes off the road and totally defeating the purpose of these phone-mirroring programs. Solving those issues can sometimes be beyond the control of the automaker. You can start to see GM's frustration. Babbitt's thesis is that if drivers were to do everything through the vehicle's built-in systems, they'd be less likely to pick up their phones and therefore less distracted and safer behind the wheel. He admits, though, GM hasn't tested this thesis in the lab or real world yet but believes it has potential, if customers go for it.

The issues Babbitt cited with CarPlay and Android Auto seem like they'd be mostly linked to using those programs wirelessly, and while he says that's true, just plugging the phone into a USB data port doesn't solve all the problems. Babbitt says even when using a physical connection, Android phones are prone to compatibility issues between the vehicle and all the various phone manufacturers running Android. iPhones, meanwhile, suffer from backwards compatibility issues that cause older iPhone models to have trouble running CarPlay consistently. He points to J.D. Power data that shows issues with CarPlay and Android Auto are common owner complaints, and that customers tend to blame the automaker rather than the phone manufacturer or phone software. In that way, eliminating CarPlay and Android Auto potentially relieves GM of a key customer complaint dragging down their perceived quality scores. After MotorTrend's story was published, GM issued the following statement: "We wanted to reach out to clarify that comments about GM's position on phone projection were misrepresented and to reinforce our valued partnerships with Apple and Google and each company's commitment to driver safety. GM's embedded infotainment strategy is driven by the benefits of having a system that allows for greater integration with the larger GM ecosystem and vehicles."

Google's making the second generation of Imagen, its AI model that can create and edit images given a text prompt, more widely available -- at least to Google Cloud customers using Vertex AI who've been approved for access. From a report: But the company isn't disclosing which data it used to train the new model -- nor introducing a way for creators who might've inadvertently contributed to the data set to opt out or apply for compensation.

Called Imagen 2, Google's enhanced model -- which was quietly launched in preview at the tech giant's I/O conference in May -- was developed using technology from Google DeepMind, Google's flagship AI lab. Compared to the first-gen Imagen, it's "significantly" improved in terms of image quality, Google claims (the company bizarrely refused to share image samples prior to this morning), and introduces new capabilities including the ability to render text and logos. "If you want to create images with a text overlay -- for example, advertising -- you can do that," Google Cloud CEO Thomas Kurian said during a press briefing on Tuesday.

An anonymous reader quotes a report from The Register: Two years after the Log4Shell vulnerability in the open source Java-based Log4j logging utility was disclosed, circa one in four applications are dependent on outdated libraries, leaving them open to exploitation. Research from security shop Veracode revealed that the vast majority of vulnerable apps may never have updated the Log4j library after it was implemented by developers as 32 percent were running pre-2015 EOL versions. Prior investigations from Veracode also showed that 79 percent of all developers never update third-party libraries after first introducing them into projects, and given that Log4j2 -- the specific version of Log4j affected by the vulnerability -- dates back to 2014, this could explain the large proportion of unpatched apps.

A far smaller minority are running versions that were vulnerable at the time of the Log4j vulnerability's disclosure in December 2021. Only 2.8 percent are still using versions 2.0-beta9 through 2.15.0 -- post-EOL versions that remain exposed to Log4Shell, the industry-coined moniker of the vulnerability's exploit. Some 3.8 percent are still running version 2.17, a post-patch version of the Java logger that's not exposed to Log4Shell attacks, but is vulnerable to a separate remote code execution (RCE) bug (CVE-2021-44832).

The researchers believe this illustrates a minority of developers that acted quickly when the vulnerability was first disclosed, as was the advice at the time, had returned to older habits of leaving libraries untouched. Altogether, just shy of 35 percent remain vulnerable to Log4Shell, and nearly 40 percent are vulnerable to RCE flaws. The EOL versions of Log4j are also vulnerable to three additional critical bugs announced by Apache, bringing the total to seven high and critical-rated issues. "At a surface level, the numbers above show that the massive effort to remediate the Log4Shell vulnerability was effective in mitigating risk of exploitation of the zero-day vulnerability. That should not be surprising," said Chris Eng, chief research officer at Veracode.

"The bigger story at the two-year anniversary, however, is that there is still room for improvement when it comes to open source software security. If Log4Shell was another example in a long series of wake-up calls to adopt more stringent open source security practices, the fact that more than one in three applications currently run vulnerable versions of Log4j shows there is more work to do.

"The major takeaway here is that organizations may not be aware of how much open source security risk they are exposed to and how to mitigate it."

According to Reuters, Ukraine's biggest mobile network was hit by "what appeared to be the largest cyber attack of the war with Russia so far," severing mobile and internet services for millions of people and knocking out the air raid alert system in parts of Kyiv. From the report: Kyivstar has 24.3 million mobile subscribers - more than half of Ukraine's population - as well as over 1.1 million home internet subscribers. Its CEO Oleksandr Komarov said the attack was "a result of" the war with Russia, although he did not say which Russian body he believed to be responsible, and that the company's IT infrastructure had been "partially destroyed." "(The attack) significantly damaged (our) infrastructure, limited access, we could not counter it at the virtual level, so we shut down Kyivstar physically to limit the enemy's access," Komarov said.

A source close to Ukraine's cyber defense also said that Russia was suspected to be the source of the attack, but no specific group had been identified. "It's definitely a state actor," said the source, who asked not to be identified because of the delicacy of the issue, adding that data cable interception showed "a lot of Russian controlled traffic directed at these networks." "There's no ransom. It's all destruction. So it's not a financially motivated attack," said the source. Ukrainian officials said that air raid alert systems in more than 75 settlements in the central Kyiv region were affected by the cyber attack.

Komarov said two databases containing customer data had been damaged and were currently locked. "The most important thing is that the personal data of users has not been compromised," Kyivstar said in its statement, promising to compensate customers for loss of access to services. Meanwhile, Ukraine's defense intelligence director (GUR) said it infected thousands of servers belonging to Russia's state tax service with malware, and destroyed databases and backups. "According to GUR's statement published Tuesday, the attack led to the 'complete destruction' of the agency's infrastructure," reports The Record. "GUR claimed they destroyed configuration files 'which for years ensured the functioning of Russia's tax system.'"

Ed Targett reports via The Stack: Broadcom is killing off VMware's on-premises perpetual licenses -- and getting set to strong-arm VMware customers onto subscriptions, by also ending the sale of Support and Subscription renewals for such customers. VMware described this to customers as part of its plan to "complete the transition of all VMware by Broadcom solutions to subscription licenses." "We are [also] ending the sale of Support and Subscription (SnS) renewals for perpetual offerings beginning today" SVP Krish Prasad said in a FAQ.

VMware perpetual licenses were described by its own Office of the CTO earlier this year in a short blog as its "most renowned licenses." The on-premises licenses for the virtualization software come with a license key, with SnS separately licensing users for support and software updates. Perpetual license keys never expire but the SnS lapses and now will not, seemingly, be renewed -- meaning that customers reluctant to shift to an alternative licensing model will be left without support or updates.

VMware customers "may continue using perpetual licenses with active support contracts. We will continue to provide support as defined in contractual commitments. We encourage customers to review their inventory of perpetual licenses, including Support Services renewal and expiration dates," Broadcom said rather menacingly, on December 10. The company is also announcing a new "bring-your-own-subscription license option, providing license portability to VMware validated hybrid cloud endpoints running VMware Cloud Foundation," it added, without initially sharing details.

Nearly 1 in 5 teenagers in the U.S. say they use YouTube and TikTok "almost constantly," according to a Pew Research Center survey. CNBC reports: The survey showed that YouTube was the most "widely used platform" for U.S.-based teenagers, with 93% of survey respondents saying they regularly use Google's video-streaming service. Of that 93% figure, about 16% of the teenage respondents said they "almost constantly visit or use" YouTube, underscoring the video app's immense popularity with the youth market. TikTok was the second-most popular app, with 63% of teens saying they use the ByteDance-owned short-video service, followed by Snapchat and Meta's Instagram, which had 60% and 59%, respectively. About 17% of the 63% of respondents who said they use TikTok indicated they access the short-video service "almost constantly," the report noted.

Meanwhile, Facebook and Twitter, now known as X, are not as popular with U.S.-based teenagers as they were a decade ago, the Pew Research study detailed. Regarding Facebook in particular, the Pew Research authors wrote that the share of teens who use the Meta-owned social media app "has dropped from 71% in 2014-2015 to 33% today." During the same period, Meta-owned Instagram's usage has not made up the difference in share, increasing from 52% in 2014-15 to a peak of 62% last year, then dropping to 59% in 2023, according to the firm.

An anonymous reader quotes a report from Ars Technica: Thirty years ago, a botanist in Germany had a simple wish: to see the inner workings of woody plants without dissecting them. By bleaching away the pigments in plant cells, Siegfried Fink managed to create transparent wood, and he published his technique in a niche wood technology journal. The 1992 paper remained the last word on see-through wood for more than a decade, until a researcher named Lars Berglund stumbled across it. Berglund was inspired by Fink's discovery, but not for botanical reasons. The materials scientist, who works at KTH Royal Institute of Technology in Sweden, specializes in polymer composites and was interested in creating a more robust alternative to transparent plastic. And he wasn't the only one interested in wood's virtues. Across the ocean, researchers at the University of Maryland were busy on a related goal: harnessing the strength of wood for nontraditional purposes.

Now, after years of experiments, the research of these groups is starting to bear fruit. Transparent wood could soon find uses in super-strong screens for smartphones; in soft, glowing light fixtures; and even as structural features, such as color-changing windows. "I truly believe this material has a promising future," says Qiliang Fu, a wood nanotechnologist at Nanjing Forestry University in China who worked in Berglund's lab as a graduate student. Wood is made up of countless little vertical channels, like a tight bundle of straws bound together with glue. These tube-shaped cells transport water and nutrients throughout a tree, and when the tree is harvested and the moisture evaporates, pockets of air are left behind. To create see-through wood, scientists first need to modify or get rid of the glue, called lignin, that holds the cell bundles together and provides trunks and branches with most of their earthy brown hues. After bleaching lignin's color away or otherwise removing it, a milky-white skeleton of hollow cells remains. This skeleton is still opaque, because the cell walls bend light to a different degree than the air in the cell pockets does -- a value called a refractive index. Filling the air pockets with a substance like epoxy resin that bends light to a similar degree to the cell walls renders the wood transparent.

The material the scientists worked with is thin -- typically less than a millimeter to around a centimeter thick. But the cells create a sturdy honeycomb structure, and the tiny wood fibers are stronger than the best carbon fibers, says materials scientist Liangbing Hu, who leads the research group working on transparent wood at the University of Maryland in College Park. And with the resin added, transparent wood outperforms plastic and glass: In tests measuring how easily materials fracture or break under pressure, transparent wood came out around three times stronger than transparent plastics like Plexiglass and about 10 times tougher than glass. "The results are amazing, that a piece of wood can be as strong as glass," says Hu, who highlighted the features of transparent wood in the 2023 Annual Review of Materials Research.

A jury in San Francisco unanimously found (PDF) that Google violated California and federal antitrust laws through deals that stifled competition for its mobile app store. "The verdict delivers the first significant US courtroom loss for big tech in the years-long campaign by rivals, regulators, and prosecutors to tame the power of internet gatekeepers," reports Wired. From the report: The lawsuit next moves to a remedies phase, meaning a judge as soon as the coming weeks will hear arguments about and decide whether to order changes to Google's business practices. Users of devices powered by Google's Android operating system could find more app options to choose from, at lower prices, if Google is forced to allow downloads of rival app stores from Play or share a greater portion of sales with developers selling digital items inside their apps.

The ruling came in a case first filed in 2020 by Epic Games, known for its blockbuster game Fortnite and tools for developers, and argued before a jury since early November. The jury of nine -- a 10th juror dropped out early in the trial -- deliberated for three hours before reaching its verdict. They faced 11 questions such as defining product and geographic markets and whether Google engaged in anticompetitive conduct in those areas. Epic had accused Google of restricting smartphone makers, wireless carriers, and app developers from providing any competition to the Play store, which accounts for over 95 percent of all downloads onto Android phones in the US. Google had denied any wrongdoing, saying that its sole aim was to provide a safe and attractive experience to users, especially as it faced competition from Apple, its iPhone, and its App Store.

Google Play Movies & TV will be replaced with Google TV on January 17, 2024. 9to5Google reports: Since the 2020 launch of the Google TV platform, that branding has replaced Play Movies & TV in areas such as mobile apps, but that's also led to the choice to do away with Play Movies & TV branding basically everywhere else. In October, that decision also made its way to Android TV, and the app has not been working ever since. Despite some confusion over the past few days, the app currently just redirects to Android TV's "Shop" tab, which has been widely available for months.

In a new post, Google explains that it will do away with the last parts of Google Play Movies & TV in January 2024: "With these changes, Google Play Movies & TV will no longer be available on Android TV devices or the Google Play website.* However, you'll still be able to access all of your previously purchased titles (including active rentals) on Android TV devices, Google TV devices, the Google TV mobile app (Android and iOS), and YouTube."

On January 17, Play Movies & TV will officially cease for good on Android TV. For anyone who does still have the app working -- again, most users cannot use the app already -- the "Shop" tab will become the only option. Similarly, Google says that Play Movies & TV will cease on other remaining platforms that same date. Any cable boxes with the app integrated will also lose it, and in turn pushed to the YouTube app for continued access to purchased content. Web access via play.google.com/movies will also go away, with youtube.com/movies becoming the alternative.

The Browser Company's Chromium-based Arc browser, which aims to rethink the whole browser UI with a sidebar for tabs and lots of personalization options, is finally coming to Windows. In a post on X, the Browser Company says it's sent out the first Windows beta invites. It's currently only available for iOS and Mac users.

Nvidia, the world's most valuable chipmaker, has become one of the most prolific investors in AI start-ups this year, seeking to capitalise on its position as the dominant provider of AI processors. From a report: Silicon Valley-based Nvidia said on Monday it had invested in "more than two dozen" companies this year, from big new AI platforms valued in the billions of dollars to smaller start-ups applying AI to industries such as healthcare or energy. According to estimates by Dealroom, which tracks venture capital investments, Nvidia participated in 35 deals in 2023, almost six times more than last year.

That made the chipmaker the most active large-scale investor in AI in a banner year for dealmaking in the sector, outstripping Silicon Valley's largest venture firms such as Andreessen Horowitz and Sequoia, according to Dealroom, excluding small-scale accelerator funds such as Y Combinator that place many smaller bets. "Broadly, for Nvidia, the number one criteria [for making start-up investments] is relevancy," Mohamed Siddeek, head of its dedicated venture arm NVentures, told the Financial Times. "Companies that use our technology, who depend on our technology, who build their businesses on our technologyâ...âI can't think of a situation where we've invested in a company that did not use Nvidia products."

The recently-departed watchdog in charge of monitoring facial recognition technology in UK has joined the private firm he controversially approved, paving the way for the mass roll-out of biometric surveillance cameras in high streets across the country. From a report: In a move critics have dubbed an "outrageous conflict of interest," Professor Fraser Sampson, former biometrics and surveillance camera commissioner, has joined Facewatch as a non-executive director. Sampson left his watchdog role on 31 October, with Companies House records showing he was registered as a company director at Facewatch the following day, 1 November.

Campaigners claim this might mean he was negotiating his Facewatch contract while in post, and have urged the advisory committee on business appointments to investigate if it may have "compromised his work in public office." It is understood that the committee is currently considering the issue. Facewatch uses biometric cameras to check faces against a watch list and, despite widespread concern over the technology, has received backing from the Home Office, and has already been introduced in hundreds of high-street shops and supermarkets.

As racetracks close and old aircraft engines get harder to find, the crowd-pleasing spectacles are endangered. From a report: Magdatude is a 1946 Chevy pickup modified with a jet engine. It wasn't put there for speed. On a rainy September night, the truck rumbled onto the infield of the Rockford Speedway in Illinois, stopping with its business end about 10 feet from a junk minibus. The engine whined to life and shot a blast of fire from its afterburner, engulfing the bus until it was reduced to a charred metal skeleton. "There's nothing left of that thing!" the announcer shouted. "Holy cow!"

It was a textbook jet car meltdown, once a common spectacle at racetracks and drag strips. The fiery craft has become endangered as venues close, spare parts grow scarce and practitioners dwindle. "I think realistically there's going to be a few people that keep it alive," said Josh Baumgartner, Magdatude's owner. "We're hoping to be among them."

A former Navy mechanic named Doug Rose helped to popularize meltdowns after he created a dragster using a jet engine from a scrapyard. According to his widow, Jeanne, he conducted his first fire show around 1968 with a car he named the Green Mamba. Over the years, he honed his craft until he could torch a half-dozen vehicles at once. "Doug's objective was to please the people," she said.

The White House is racing to overcome internal differences and hash out a new policy over how the US and other governments should view the rapid rise of global data flows that are fueling everything from AI to advanced manufacturing. From a report: In a series of sessions due to begin on Wednesday, President Joe Biden's national security and economic teams are due to meet with companies, labor and human rights advocates, and other experts on the digital economy as part of a review launched last month, according to people directly involved. At issue is laying out a clear US position on the rules for the global internet as governments confront an accelerating amount of data flowing across borders with mounting economic, privacy, income inequality and national security consequences.

Coming just days after the EU agreed late Friday to new regulations for AI, the Biden administration's push highlights how governments are racing to figure out their role in a fast-evolving digital economy and competing to lead the conversation. [...] In an interview, a senior administration official said the US was not backing away from long-standing US advocacy for a free and open internet even as some governments around the world are increasingly trying to restrict information flows.

"The machines in the facility waft air towards a water-based solvent," reports the Times of London, "which carbon dioxide in the air dissolves into. An electrical current then separates those compounds from the solvent, creating a pure stream of CO2."

More details from Sky News: The UK's first-ever direct air capture plant has been turned on to remove CO2 from the atmosphere and turn it into jet fuel. The machine, developed by Mission Zero Technologies in partnership with the University of Sheffield, will run on solar power to recover 50 tonnes of CO2 from the air per year and turn it into Sustainable Aviation Fuel (SAF)...

Aviation accounts for about 2% of the world's emissions and Ihab Ahmed, research associate from the University of Sheffield, said the fuel has the capacity to massively reduce the impact of aviation on the environment — and is an important step towards the government's ambitious target to increase the use of SAF to at least 10% by 2030.
America opened its first carbon-capture facility in November in a warehouse in California. While the carbon isn't converted into sustainable air fuel, it can capture a maximum of 1,000 tons of carbon dioxide per year/

Slow load times? Choppy videos? The real problem is latency, writes the Verge — but the good news is "there's a plan to almost eliminate latency, and big companies like Apple, Google, Comcast, Charter, Nvidia, Valve, Nokia, Ericsson, T-Mobile parent company Deutsche Telekom, and more have shown an interest." It's a new internet standard called L4S that was finalized and published in January, and it could put a serious dent in the amount of time we spend waiting around for webpages or streams to load and cut down on glitches in video calls. It could also help change the way we think about internet speed and help developers create applications that just aren't possible with the current realities of the internet... L4S stands for Low Latency, Low Loss, Scalable Throughput, and its goal is to make sure your packets spend as little time needlessly waiting in line as possible by reducing the need for queuing. To do this, it works on making the latency feedback loop shorter; when congestion starts happening, L4S means your devices find out about it almost immediately and can start doing something to fix the problem. Usually, that means backing off slightly on how much data they're sending... [L4S] makes it easier to maintain a good amount of data throughput without adding latency that increases the amount of time it takes for data to be transferred...

If you really want to get into it (and you know a lot about networking), you can read the specification paper on the Internet Engineering Task Force's website... The L4S standard adds an indicator to packets, which says whether they experienced congestion on their journey from one device to another. If they sail right on through, there's no problem, and nothing happens. But if they have to wait in a queue for more than a specified amount of time, they get marked as having experienced congestion. That way, the devices can start making adjustments immediately to keep the congestion from getting worse and to potentially eliminate it altogether... In terms of reducing latency on the internet, L4S or something like it is "a pretty necessary thing," according to Greg White, a technologist at research and development firm CableLabs who helped work on the standard. "This buffering delay typically has been hundreds of milliseconds to even thousands of milliseconds in some cases. Some of the earlier fixes to buffer bloat brought that down into the tens of milliseconds, but L4S brings that down to single-digit milliseconds...."

Here's the bad news: for the most part, L4S isn't in use in the wild yet. However, there are some big names involved with developing it... When we spoke to Greg White from CableLabs, he said there were already around 20 cable modems that support it today and that several ISPs like Comcast, Charter, and Virgin Media have participated in events meant to test how prerelease hardware and software work with L4S. Companies like Nokia, Vodafone, and Google have also attended, so there definitely seems to be some interest. Apple put an even bigger spotlight on L4S at WWDC 2023 after including beta support for it in iOS 16 and macOS Ventura... At around the same time as WWDC, Comcast announced the industry's first L4S field trials in collaboration with Apple, Nvidia, and Valve. That way, content providers can mark their traffic (like Nvidia's GeForce Now game streaming), and customers in the trial markets with compatible hardware like the Xfinity 10G Gateway XB7 / XB8, Arris S33, or Netgear CM1000v2 gateway can experience it right now...

The other factor helping L4S is that it's broadly compatible with the congestion control systems in use today...
