Lauren Forristal writes via TechCrunch: Netflix announced during its Upfronts presentation on Wednesday that it's launching its own advertising technology platform only a year and a half after entering the ads business. This move pits it against other industry heavyweights with ad servers, like Google, Amazon and Comcast. The announcement signifies a significant shake-up in the streaming giant's advertising approach. The company originally partnered with Microsoft to develop its ad tech, letting Netflix enter the ad space quickly and catch up with rivals like Hulu, which has had its own ad server for over a decade.

With the launch of its in-house ad tech, Netflix is poised to take full control of its advertising future. This strategic move will empower the company to create targeted and personalized ad experiences that resonate with its massive user base of 270 million subscribers. [...] Netflix didn't say exactly how its in-house solution will change the way ads are delivered, but it's likely it'll move away from generic advertisements. According to the Financial Times, Netflix wants to experiment with "episodic" campaigns, which involve a series of ads that tell a story rather than delivering repetitive ads. During the presentation, Netflix also noted that it'll expand its buying capabilities this summer, which will now include The Trade Desk, Google's Display & Video 360 and Magnite as partners. Notably, competitor Disney+ also has an advertising agreement with The Trade Desk. Netflix also touted the success of its ad-supported tier, reporting that 40 million global monthly active users opt for the plan. The ad tier had around 5 million users within six months of launching.

Police officers in Britain could be armed with Ghostbusters-style devices that fire electromagnetic rays to shut down the engines of ebikes being used in a crime. From a report: Gavin Stephens, chair of the National Police Chiefs' Council (NPCC), said the weapon was in development and could be months away from being available, though it is expected to be longer than that. He said it would be housed in a backpack, reminiscent of the equipment used in the Ghostbusters series of movies. It could tackle crime linked to newer vehicles such as electric bikes and electric scooters.

The device is being developed with the Defence Science and Technology Lab, which is overseen by the Ministry of Defence, alongside other technological innovations that British police are hoping to use. It would fire an electromagnetic pulse at a vehicle that an officer wants to stop because the rider is suspected of involvement in a crime. The electromagnetic weapon works by tricking the engine into thinking it is overheating, which shuts down the engine and brings the vehicle to a stop. It requires a line of sight to work, Stephens said.

Stephens told a media briefing: "Basically, it interferes with the electric motor, to trick the electric motor into thinking it is overheating. It sends a signal to confuse the electric motor. All these electric motors apparently have an inbuilt safety system that if it thinks it's overheating, it shuts down. At the minute, it's like a ginormous backpack." The equipment was demonstrated to police leaders at the Farnborough technology show earlier this year. Stephens said: "They were also telling me it has the potential to be useful with normal combustion engine vehicles."

An anonymous reader quotes a report from New Scientist: Efforts to build a global quantum internet have received a boost from two developments in quantum information storage that could one day make it possible to communicate securely across hundreds or thousands of kilometers. The internet as it exists today involves sending strings of digital bits, or 0s and 1s, in the form of electrical or optical signals, to transmit information. A quantum internet, which could be used to send unhackable communications or link up quantum computers, would use quantum bits instead. These rely on a quantum property called entanglement, a phenomenon in which particles can be linked and measuring one particle instantly influences the state of another, no matter how far apart they are. Sending these entangled quantum bits, or qubits, over very long distances, requires a quantum repeater, a piece of hardware that can store the entangled state in memory and reproduce it to transmit it further down the line. These would have to be placed at various points on a long-distance network to ensure a signal gets from A to B without being degraded.

Quantum repeaters don't yet exist, but two groups of researchers have now demonstrated long-lasting entanglement memory in quantum networks over tens of kilometers, which are the key characteristics needed for such a device. Can Knaut at Harvard University and his colleagues set up a quantum network consisting of two nodes separated by a loop of optical fibre that spans 35 kilometers across the city of Boston. Each node contains both a communication qubit, used to transmit information, and a memory qubit, which can store the quantum state for up to a second. "Our experiment really put us in a position where we're really close to working on a quantum repeater demonstration," says Knaut. To set up the link, Knaut and his team entangled their first node, which contains a type of diamond with an atom-sized hole in it, with a photon that they sent to their second node, which contains a similar diamond. When the photon arrives at the second diamond, it becomes entangled with both nodes. The diamonds are able to store this state for a second. A fully functioning quantum repeater using similar technology could be demonstrated in the next couple of years, says Knaut, which would enable quantum networks connecting cities or countries.

In separate work, Xiao-Hui Bao at the University of Science and Technology of China and his colleagues entangled three nodes together, each separated by around 10 kilometers in the city of Hefei. Bao and his team's nodes use supercooled clouds of hundreds of millions of rubidium atoms to generate entangled photons, which they then sent across the three nodes. The central of the three nodes is able to coordinate these photons to link the atom clouds, which act as a form of memory. The key advance for Bao and his team's network is to match the frequency of the photons meeting at the central node, which will be crucial for quantum repeaters connecting different nodes. While the storage time was less than Knaut's team, at 100 microseconds, it is still long enough to perform useful operations on the transmitted information.

Google is opening up API access to its Google Home smart home platform, allowing app developers to access over 600 million connected devices and tap into the Google Home automation engine. In addition, Google announced that it'll be turning Google TVs into Google Home hubs and Matter controllers. The Verge reports: The Home APIs can access any Matter device or Works with Google Home device, and allows developers to build their own experiences using Google Home devices and automations into their apps on both iOS and Android. This is a significant move for Google in opening up its smart home platform, following shutting down its Works with Nest program back in 2019. [...] The Home APIs are already available to Google's early access partners, and Google is opening up a waitlist for any developer to sign up today. "We are opening up access on a rolling basis so they can begin building and testing within their apps," Anish Kattukaran, head of product at Google Home and Nest, told The Verge. "The first apps using the home APIs will be able to publish to the Play and App stores in the fall."

The access is not just limited to smart home developers. In the blog post, Matt Van Der Staay, engineering director at Google Home, said the Home APIs could be used to connect smart home devices to fitness or delivery apps. "You can build a complex app to manage any aspect of a smart home, or simply integrate with a smart device to solve pain points -- like turning on the lights automatically before the food delivery driver arrives." The APIs allow access to most devices connected to Google Home and to the Google Home structure, letting apps control and manage devices such as Matter light bulbs or the Nest Learning Thermostat. They also leverage Google Home's automation signals, such as motion from sensors, an appliance's mode changing, or Google's Home and Away mode, which uses various signals to determine if a home is occupied. [...]

What's also interesting here is that developers will be able to use the APIs to access and control any device that works with the new smart home standard Matter and even let people set up Matter devices directly in their app. This should make it easier for them to implement Matter into their apps, as it will add devices to the Google Home fabric, so they won't have to develop their own. In addition, Google announced that it's vastly expanding its Matter infrastructure by turning Google TVs into Google Home hubs and Matter controllers. Any app using the APIs would need a Google hub in a customer's home in order to control Matter devices locally. Later this year, Chromecast with Google TV, select panel TVs with Google TV running Android 14 or higher, and some LG TVs will be upgraded to become Google Home hubs.

Additionally, Kattukaran said Google will upgrade all of its existing home hubs -- which include Nest Hub (second-gen), Nest Hub Max, and Google Wifi -- with a new ability called Home runtime. "With this update, all hubs for Google Home will be able to directly route commands from any app built with Home APIs (such as the Google Home app) to a customer's Matter device locally, when the phone is on the same Wi-Fi network as the hub," said Kattukaran. This means you should see "significant latency improvements using local control via a hub for Google Home," he added.

An anonymous reader quotes a report from Ars Technica: Google's I/O conference is still happening, and while the big keynote was yesterday, major Android beta releases have apparently been downgraded to Day 2 of the show. Google really seems to want to be primarily an AI company now. Android already had some AI news yesterday, but now that the code-red requirements have been met, we have actual OS news. One of the big features in this release is "Private Space," which Google says is a place where users can "keep sensitive apps away from prying eyes, under an additional layer of authentication."

First, there's a new hidden-by-default portion of the app drawer that can hold these sensitive apps, and revealing that part of the app drawer requires a second round of lock-screen authentication, which can be different from the main phone lock screen. Just like "Work" apps, the apps in this section run on a separate profile. To the system, they are run by a separate "user" with separate data, which your non-private apps won't be able to see. Interestingly, Google says, "When private space is locked by the user, the profile is paused, i.e., the apps are no longer active," so apps in a locked Private Space won't be able to show notifications unless you go through the second lock screen.

Another new Android 15 feature is "Theft Detection Lock," though it's not in today's beta and will be out "later this year." The feature uses accelerometers and "Google AI" to "sense if someone snatches your phone from your hand and tries to run, bike, or drive away with it." Any of those theft-like shock motions will make the phone auto-lock. Of course, Android's other great theft prevention feature is "being an Android phone." Android 12L added a desktop-like taskbar to the tablet UI, showing recent and favorite apps at the bottom of the screen, but it was only available on the home screen and recent apps. Third-party OEMs immediately realized that this bar should be on all the time and tweaked Android to allow it. In Android 15, an always-on taskbar will be a normal option, allowing for better multitasking on tablets and (presumably) open foldable phones. You can also save split-screen-view shortcuts to the taskbar now.

An Android 13 developer feature, predictive back, will finally be turned on by default. When performing the back gesture, this feature shows what screen will show up behind the current screen you're swiping away. This gives a smoother transition and a bit of a preview, allowing you to cancel the back gesture if you don't like where it's going. [...] Because this is a developer release, there are tons of under-the-hood changes. Google is a big fan of its own next-generation AV1 video codec, and AV1 support has arrived on various devices thanks to hardware decoding being embedded in many flagship SoCs. If you can't do hardware AV1 decoding, though, Android 15 has a solution for you: software AV1 decoding.

In an op-ed for The Wall Street Journal, Representatives Cathy McMorris Rodgers (R-Wash.) and Frank Pallone Jr (D-N.J.) made their case for why Section 230 of the 1996 Communications Decency Act has "outlived its usefulness." Section 230 of the Communications Decency Act protects online platforms from liability for user-generated content, allowing them to moderate content without being treated as publishers.

"Unfortunately, Section 230 is now poisoning the healthy online ecosystem it once fostered. Big Tech companies are exploiting the law to shield them from any responsibility or accountability as their platforms inflict immense harm on Americans, especially children. Congress's failure to revisit this law is irresponsible and untenable," the lawmakers wrote. The Hill reports: Rodgers and Pallone argued that rolling back the protections on Big Tech companies would hold them accountable for the material posted on their platforms. "These blanket protections have resulted in tech firms operating without transparency or accountability for how they manage their platforms. This means that a social-media company, for example, can't easily be held responsible if it promotes, amplifies or makes money from posts selling drugs, illegal weapons or other illicit content," they wrote.

The lawmakers said they were unveiling legislation (PDF) to sunset Section 230. It would require Big Tech companies to work with Congress for 18 months to "evaluate and enact a new legal framework that will allow for free speech and innovation while also encouraging these companies to be good stewards of their platforms." "Our bill gives Big Tech a choice: Work with Congress to ensure the internet is a safe, healthy place for good, or lose Section 230 protections entirely," the lawmakers wrote.

At Google I/O on Tuesday, Google previewed a feature that will alert users to potential scams during a phone call. TechCrunch reports: The feature, which will be built into a future version of Android, uses Gemini Nano, the smallest version of Google's generative AI offering, which can be run entirely on-device. The system effectively listens for "conversation patterns commonly associated with scams" in real time. Google gives the example of someone pretending to be a "bank representative." Common scammer tactics like password requests and gift cards will also trigger the system. These are all pretty well understood to be ways of extracting your money from you, but plenty of people in the world are still vulnerable to these sorts of scams. Once set off, it will pop up a notification that the user may be falling prey to unsavory characters.

No specific release date has been set for the feature. Like many of these things, Google is previewing how much Gemini Nano will be able to do down the road sometime. We do know, however, that the feature will be opt-in.

At Google I/O today, Google introduced a "next-generation AI assistant" called Project Astra that can "make sense of what your phone's camera sees," reports Wired. It follows yesterday's launch of GPT-4o, a new AI model from OpenAI that can quickly respond to prompts via voice and talk about what it 'sees' through a smartphone camera or on a computer screen. It "also uses a more humanlike voice and emotionally expressive tone, simulating emotions like surprise and even flirtatiousness," notes Wired. From the report: In response to spoken commands, Astra was able to make sense of objects and scenes as viewed through the devices' cameras, and converse about them in natural language. It identified a computer speaker and answered questions about its components, recognized a London neighborhood from the view out of an office window, read and analyzed code from a computer screen, composed a limerick about some pencils, and recalled where a person had left a pair of glasses. [...] Google says Project Astra will be made available through a new interface called Gemini Live later this year. [Demis Hassabis, the executive leading the company's effort to reestablish leadership inÂAI] said that the company is still testing several prototype smart glasses and has yet to make a decision on whether to launch any of them.

Hassabis believes that imbuing AI models with a deeper understanding of the physical world will be key to further progress in AI, and to making systems like Project Astra more robust. Other frontiers of AI, including Google DeepMind's work on game-playing AI programs could help, he says. Hassabis and others hope such work could be revolutionary for robotics, an area that Google is also investing in. "A multimodal universal agent assistant is on the sort of track to artificial general intelligence," Hassabis said in reference to a hoped-for but largely undefined future point where machines can do anything and everything that a human mind can. "This is not AGI or anything, but it's the beginning of something."

At its I/O developer conference today, Google announced Veo, its latest generative AI video model, that "can generate 'high-quality' 1080p resolution videos over a minute in length in a wide variety of visual and cinematic styles," reports The Verge. From the report: Veo has "an advanced understanding of natural language," according to Google's press release, enabling the model to understand cinematic terms like "timelapse" or "aerial shots of a landscape." Users can direct their desired output using text, image, or video-based prompts, and Google says the resulting videos are "more consistent and coherent," depicting more realistic movement for people, animals, and objects throughout shots. Google DeepMind CEO Demis Hassabis said in a press preview on Monday that video results can be refined using additional prompts and that Google is exploring additional features to enable Veo to produce storyboards and longer scenes.

As is the case with many of these AI model previews, most folks hoping to try Veo out themselves will likely have to wait a while. Google says it's inviting select filmmakers and creators to experiment with the model to determine how it can best support creatives and will build on these collaborations to ensure "creators have a voice" in how Google's AI technologies are developed. Some Veo features will also be made available to "select creators in the coming weeks" in a private preview inside VideoFX -- you can sign up for the waitlist here for an early chance to try it out. Otherwise, Google is also planning to add some of its capabilities to YouTube Shorts "in the future." Along with its new AI models and tools, Google said it's expanding its AI content watermarking and detection technology. The company's new upgraded SynthID watermark imprinting system "can now mark video that was digitally generated, as well as AI-generated text," reports The Verge in a separate report.

Dan Robinson reports via The Register: VMware has made another small but notable post-merger concession to users: the Workstation Pro and Fusion Pro desktop hypervisor products will now be free for personal use. The cloud and virtualization biz, now a Broadcom subsidiary, has announced that its Pro apps will be available under two license models: a "Free Personal Use" or a "Paid Commercial Use" subscription for organizations. Workstation Pro is available for PC users running Windows or Linux, while Fusion Pro is available for Mac systems with either Intel CPUs or Apple's own processors. The two products allow users to create a virtual machine on their local computer for the purpose of running a different operating system or creating a sandbox in which to run certain software. [...]

According to VMware, users will get to decide for themselves if their use case calls for a commercial subscription. There are no functional differences between the two versions, the company states, and the only visual difference is that the free version displays the text: "This product is licensed for personal use only." "This means that everyday users who want a virtual lab on their Mac, Windows, or Linux computer can do so for free simply by registering and downloading the bits from the new download portal located at support.broadcom.com," VMware says. Customers that require a paid commercial subscription must purchase through an authorized Broadcom Advantage partner.

The move also means that VMware's Workstation Player and Fusion Player products are effectively redundant as the Pro products now serve the same role, and so those will no longer be offered for purchase. Organizations with commercial licenses for Fusion Player 13 or Workstation Player 17 can continue to use these, however, and they will continue to be supported for existing end of life (EOL) and end of general support (EoGS) dates.

An anonymous reader quotes a report from Ars Technica: Crashing into parked cars, drifting over into oncoming traffic, intruding into construction zones -- all this "unexpected behavior" from Waymo's self-driving vehicles may be violating traffic laws, the US National Highway Traffic Safety Administration (NHTSA) said (PDF) Monday. To better understand Waymo's potential safety risks, NHTSA's Office of Defects Investigation (ODI) is now looking into 22 incident reports involving cars equipped with Waymo's fifth-generation automated driving system. Seventeen incidents involved collisions, but none involved injuries.

Some of the reports came directly from Waymo, while others "were identified based on publicly available reports," NHTSA said. The reports document single-party crashes into "stationary and semi-stationary objects such as gates and chains" as well as instances in which Waymo cars "appeared to disobey traffic safety control devices." The ODI plans to compare notes between incidents to decide if Waymo cars pose a safety risk or require updates to prevent malfunctioning. There is already evidence from the ODI's initial evaluation showing that Waymo's automated driving systems (ADS) were either "engaged throughout the incident" or abruptly "disengaged in the moments just before an incident occurred," NHTSA said. The probe is the first step before NHTSA can issue a potential recall, Reuters reported. A Waymo spokesperson said the company currently serves "over 50,000 weekly trips for our riders in some of the most challenging and complex environments." When a collision occurs, Waymo reviews each case and continually updates the ADS software to enhance performance.

"We are proud of our performance and safety record over tens of millions of autonomous miles driven, as well as our demonstrated commitment to safety transparency," Waymo's spokesperson said, confirming that Waymo would "continue to work" with the ODI to enhance ADS safety.

A portal linking New York City to Dublin via a livestream has been temporarily shut down after inappropriate behavior ensued, according to the Dublin City Council. From a report: Less than a week after the 24/7 visual art installation was put in place, officials have opted to close it down temporarily after people began to flash each other, grind on the portal, and one person even shared pictures of the twin tower attack to people in New York City. Alternatively, the portal had also been the site of reunions with old friends and even a proposal, with many documenting their experience with the installation online.

The Dublin City Council said that although those engaged in the inappropriate behavior were few and far between, videos of said behavior went viral online. "While we cannot control all of these actions, we are implementing some technical solutions to address this and these will go live in the next 24 hours," the council said in a Monday statement. "We will continue to monitor the situation over the coming days with our partners in New York to ensure that portals continue to deliver a positive experience for both cities and the world."

An anonymous reader shares a report: Google's Gemini AI often just feels like a chatbot built into a text-input field, but you can really start to do special things when you give it access to a ton of data. Gemini in Gmail will soon be able to search through your entire backlog of emails and show a summary in a sidebar. That's simple to describe but solves a huge problem with email: even searching brings up a list of email subjects, and you have to click-through to each one just to read it.

Having an AI sift through a bunch of emails and provide a summary sounds like a huge time saver and something you can't do with any other interface. Google's one-minute demo of this feature showed a big blue Gemini button at the top right of the Gmail web app. Tapping it opens the normal chatbot sidebar you can type in. Asking for a summary of emails from a certain contact will get you a bullet-point list of what has been happening, with a list of "sources" at the bottom that will jump you right to a certain email. In the last second of the demo, the user types, "Reply saying I want to volunteer for the parent's group event," hits "enter," and then the chatbot instantly, without confirmation, sends an email.

Marc Whitten, Unity Create's chief product and technology officer, is stepping down on June 1, 2024, following the company's contentious Runtime Fee policy. Whitten will assist with the transition until December 31, 2024. The now-discarded Runtime Fee, announced in September 2023, faced severe backlash from developers who viewed it as a punitive per-install tariff. Unity reworked the fee and acknowledged its lack of communication with developers. CEO John Riccitiello also departed in October 2023, succeeded by Matthew Bromberg. Upon resignation, Whitten will receive a total of $814,801 in various payouts and benefits.

Among Google's swath of new AI models and tools announced today, the company is also expanding its AI content watermarking and detection technology to work across two new mediums. The Verge: Google's DeepMind CEO, Demis Hassabis, took the stage for the first time at the Google I/O developer conference on Tuesday to talk not only about the team's new AI tools, like the Veo video generator, but also about the new upgraded SynthID watermark imprinting system. It can now mark video that was digitally generated, as well as AI-generated text.

[...] Google had also enabled SynthID to inject inaudible watermarks into AI-generated music that was made using DeepMind's Lyria model. SynthID is just one of several AI safeguards in development to combat misuse by the tech, safeguards that the Biden administration is directing federal agencies to build guidelines around.

Google is shaking up Search. On Tuesday, the company announced big new AI-powered changes to the world's dominant search engine at I/O, Google's annual conference for developers. From a report: With the new features, Google is positioning Search as more than a way to simply find websites. Instead, the company wants people to use its search engine to directly get answers and help them with planning events and brainstorming ideas. "[With] generative AI, Search can do more than you ever imagined," wrote Liz Reid, vice president and head of Google Search, in a blog post. "So you can ask whatever's on your mind or whatever you need to get done -- from researching to planning to brainstorming -- and Google will take care of the legwork."

Google's changes to Search, the primary way that the company makes money, are a response to the explosion of generative AI ever since OpenAI's ChatGPT released at the end of 2022. [...] Starting today, Google will show complete AI-generated answers in response to most search queries at the top of the results page in the US. Google first unveiled the feature a year ago at Google I/O in 2023, but so far, anyone who wanted to use the feature had to sign up for it as part of the company's Search Labs platform that lets people try out upcoming features ahead of their general release. Google is now making AI Overviews available to hundreds of millions of Americans, and says that it expects it to be available in more countries to over a billion people by the end of the year.

An anonymous reader shares a report: At a privately held event, Google recently demonstrated a special build of Chromium OS -- code-named "ferrochrome" -- running in a virtual machine on a Pixel 8. However, Chromium OS wasn't shown running on the phone's screen itself. Rather, it was projected to an external display, which is possible because Google recently enabled display output on its Pixel 8 series. Time will tell if Google is thinking of positioning Chrome OS as a platform for its desktop mode ambitions and Samsung DeX rival.

Meta is shutting down Workplace, the tool it sold to businesses that combined social and productivity features, according to messages to customers obtained by Axios and confirmed by Meta. From the report:Meta has been cutting jobs and winnowing its product line for the last few years while investing billions first in the metaverse and now in AI. Micah Collins, Meta's senior director of product management, sent a message to customers alerting them of the shutdown.

Collins said customers can use Workplace through September 2025, when it will become available only to download or read existing data. The service will shut down completely in 2026. Workplace was formerly Facebook at Work, and launched in its current form in 2016. In 2021 the company reported it had 7 million paid subscribers.

According to a new study published in the journal Technology, Mind and Behavior, researchers found that internet use is associated with greater wellbeing in people around the world. "Our analysis is the first to test whether or not internet access, mobile internet access and regular use of the internet relates to wellbeing on a global level," said Prof Andrew Przybylski, of the University of Oxford, who co-authored the work. The Guardian reports: [T]he study describes how Przybylski and Dr Matti Vuorre, of Tilburg University in the Netherlands, analysed data collected through interviews involving about 1,000 people each year from 168 countries as part of the Gallup World Poll. Participants were asked about their internet access and use as well as eight different measures of wellbeing, such as life satisfaction, social life, purpose in life and feelings of community wellbeing.

The team analyzed data from 2006 to 2021, encompassing about 2.4 million participants aged 15 and above. The researchers employed more than 33,000 statistical models, allowing them to explore various possible associations while taking into account factors that could influence them, such as income, education, health problems and relationship status. The results reveal that internet access, mobile internet access and use generally predicted higher measures of the different aspects of wellbeing, with 84.9% of associations between internet connectivity and wellbeing positive, 0.4% negative and 14.7% not statistically significant.

The study was not able to prove cause and effect, but the team found measures of life satisfaction were 8.5% higher for those who had internet access. Nor did the study look at the length of time people spent using the internet or what they used it for, while some factors that could explain associations may not have be considered. Przybylski said it was important that policy on technology was evidence-based and that the impact of any interventions was tracked.

Cruise's autonomous vehicles have resumed operation in Phoenix, Arizona, following an incident in San Francisco last October where a driverless vehicle dragged a pedestrian. The Verge reports: Cruise spokesperson Tiffany Testo said the company is deploying only two autonomous vehicles with safety drivers behind the wheel. In addition, the company has eight manually driven vehicles in the city. Eventually, the service area will "gradually expand" to include Scottsdale, Paradise Valley, Tempe, Mesa, Gilbert, and Chandler -- "measured against predetermined safety benchmarks."

Cruise's slow return to the road is noteworthy, given the huge hurdles facing the company in the wake of the October incident. Regulators accused the company of misleading them about the nature and severity of the incident, in which a pedestrian was dragged over 20 feet by a driverless Cruise after first being struck by a hit-and-run driver.

Several top executives have since left the company, including founder and CEO Kyle Vogt, and around a quarter of employees were laid off. GM has said it will reduce its spending on Cruise. And an outside report found evidence that a culture of antagonism toward regulators contributed to many of the failings.
