Sam Altman (L) and Elon Musk Getty Images Jurors on Wednesday sat for a final day of testimony in the Musk v. Altman showdown. A trophy and a tantrum figured prominently, and LinkedIn cofounder Reid Hoffman was name-dropped. Closing arguments and the start of jury deliberations are expected on Thursday. After three weeks of testimony that has shed new light on some of Silicon Valley's biggest names, the Musk v. Altman jury trial is finally coming to a close. OpenAI wrapped up its case on Wednesday. Closing arguments are scheduled for Thursday morning, and the jury is expected to start deliberations thereafter. Musk has accused OpenAI's Sam Altman and Greg Brockman of "looting" the charity they founded together in 2015. OpenAI says Musk's claims are driven by "jealousy" and that he left the company in 2018 after failing to gain control. On Wednesday, OpenAI trotted out a string of executives who painted a picture of a company that had no choice but to partner with a tech giant like Microsoft to compete with rivals like Google and Anthropic. See what was revealed during the jury's last day of testimony in this blockbuster case, which has the potential to reshape the AI landscape. OpenAI's Chief Futurist Joshua Achiam arrives to court in Oakland, California for the Musk v Altman trial. Benjamin Fanjoy/Getty Images OpenAI's "futurist" recalls 'tense exchange' where Elon Musk called him a 'jackass' Joshua Achiam, OpenAI's chief futurist, was probably the most memorable witness of the day. He told jurors about a companywide meeting where Musk answered questions about his planned departure from OpenAI in 2018. Musk told the crowd of 50 or 60 people that he was leaving OpenAI to start his own competing AI. He said he wanted to "build it very fast, because he was very worried that someone else, if they got it, would do the wrong thing with it," Achiam said. Achaim said he challenged Musk on the safety of this approach, which he called "unsafe and reckless." "How did Musk respond," OpenAI's lawyer Randall Jackson asked. "Defensively," Achiam said. "We had a pretty tense exchange, and he snapped and called me a jackass." Protesters poked fun at Elon Musk outside the Oakland federal courthouse where the Tesla CEO's civil claim against OpenAI and Microsoft is being tried. Josh Elelson/AFP via Getty Images OpenAI's lawyers sought to prove the 'jackass' exchange — with evidence In an effort to prove Achiam's story, OpenAI's lawyers brought a trophy to court that the futurist said he received after his heated exchange with Musk. On the witness stand, Achiam described the trophy as "a small golden jackass, inscribed with: 'never stop being a jackass for safety.'" He said his then-colleagues, Dario Amodei and David Luan, gave it to him as a thank-you for standing up to the Tesla CEO. Lead OpenAI attorney William Savitt told reporters after the day's session that Wednesday had been the first time he'd touched the statue. The futurist had to do without the visual aid, however. Judge Yvonne Gonzalez Rogers did not accept the trophy as evidence, so it did not appear before the jury. Elon Musk at court in his civil trial against OpenAI and Sam Altman. Benjamin Fanjoy/Getty Images OpenAI turned a Musk expert's testimony against him Musk and Altman have presented dueling experts on a question at the core of the trial — was the nonprofit that runs OpenAI hurt or helped by its $13 billion partnership with Microsoft? Musk's expert testified last week that the partnership was indeed hurt, supporting the Tesla CEO's contention that in partnering with Microsoft, OpenAI betrayed the company's nonprofit origins and mission. But on Thursday, OpenAI's expert, John Coates, used Musk's expert's own pie chart and testimony against him. The partnership has "generated value for the nonprofit that I believe he himself accepted was in the $200 billion range in his own testimony," Coates said, referencing Musk expert Daniel Schizer. "If that's not faring well, I don't know what faring well is." The LinkedIn co-founder was name-dropped as jury testimony wrapped on Thursday. Kimberly White/Getty Images Microsoft's CTO once questioned how Reid Hoffman would feel about it partnering with OpenAI In a scored point for Musk, the jury learned Thursday that Microsoft's own CTO once raised concerns about how OpenAI's early nonprofit donors, including LinkedIn cofounder Reid Hoffman, would react to a partnership. "I wonder if the big OpenAI donors are aware of these plans," Chief Technology Officer Kevin Scott said in a 2018 email he was asked to read aloud to jurors. In it, Scott said he doubted donors would appreciate OpenAI using their seed money to "go build a for-profit thing." Scott was being questioned by an OpenAI lawyer, who may have wanted jurors to quickly hear Scott's explanation: that he only had a "vague awareness" of what was happening at OpenAI at the time. Scott also told the jury he wasn't thinking about Musk when he made the remark. "Primarily, I was thinking about Reid Hoffman. He was the OpenAI donor I knew," Scott said, adding, "I wasn't thinking about anyone besides him." Jurors heard again a videotaped deposition by former OpenAI executive Mira Murati. Bloomberg/Getty Images OpenAI lawyers hit rewind on damning depos to make their case Last week, Musk's lawyers played a series of videotaped depositions from former OpenAI board members and executives who complained about Altman, including the "culture of lying" they say he created at OpenAI. On Wednesday, OpenAI's lawyers hit play on some of the same tapes to make a different point: Those same people supported the ChatGPT maker's partnerships with Microsoft, which is at the heart of Musk's claims. "We realized this was the best path forward for building what OpenAI was deciding to build," former board member Tasha McCauley said about OpenAI's 2019 deal with Microsoft. She made similar statements about Microsoft's 2023 investment in OpenAI. Former OpenAI tech chief Mira Murati also described OpenAI's dealings with Microsoft as in line with the company's mission. "Do you think investments gave Microsoft undue control over OpenAI," the lawyer asked Murati. "No," she said. Correction: May 14, 2026 — An earlier version of this story misstated Mira Murati's role at OpenAI. She was OpenAI's chief technology officer, not a former board member.

Anthropic CFO Krishna Rao said AI is collapsing hours of office work into minutes and changing what employees actually do all day. Bloomberg/Getty Images Anthropic CFO Krishna Rao said AI has reshaped Anthropic's white-collar work environment. Execution roles turned into supervisors of AI, requiring higher "talent density" across the company. Anthropic's AI, Claude, now writes 90% of the company's code and handles most of its finance work. Anthropic CFO Krishna Rao says AI now writes 90% of the company's code — and it's changing what white-collar workers do all day. Rao, on an episode of Patrick O'Shaughnessy's "Invest Like the Best" podcast published Wednesday, described a workplace inside Anthropic where AI systems increasingly handle the execution layer of knowledge work — from software engineering to financial reporting — while humans shift toward oversight, judgment, and strategy. "We've hired a lot more people because of that," Rao said, adding that he sees Claude as a productivity "accelerant." "That actually means that we can get a lot more done, and that even as we grow the team, those people are more productive as they come up the curve on how to use Claude within our company. And I think that's starting to be true across many companies as well. " The comments offer a glimpse into how one of Silicon Valley's leading AI companies believes artificial intelligence will reshape white-collar jobs: not necessarily by eliminating workers outright, but by automating large portions of their day-to-day tasks and turning employees into supervisors of AI systems. The shift is already happening inside Anthropic itself, Rao said. "90 plus percent of our code is actually written by Claude Code," he said, referring to Anthropic's AI coding product. The company's finance team is undergoing a similar transformation, Rao said. Anthropic now uses Claude to produce financial statements, while its monthly financial review process is "90 to 95% ready" before humans step in to review and interpret the results. "What used to take hours to produce," Rao said of some internal reports, "now comes down to 30 minutes." Rao argued that the productivity gains have allowed Anthropic employees to spend less time gathering information and more time making decisions about it. "I think of it as, you know, accentuating and accelerating the talent that we already have," Rao said. "We talk a lot about how talent density beats talent mass, and I think that's true here — like, we want the densest collection of AI research talent, and inference engineering talent. And that, enabled with the best models, we think is a really winning combination." AI's effect on the workforce Details about how Anthropic's staff use AI come as companies across industries race to integrate the technology in the workplace. Some firms have pushed employees to adopt AI as automation capabilities improve, while others have cut jobs, citing new AI-driven efficiencies. The shift has fueled a growing debate among economists and executives over whether AI will ultimately replace white-collar workers or make them more productive. Some warn automation could eliminate jobs faster than new ones can be created, while others argue productivity gains could ultimately increase labor demand. As employees become more productive with AI assistance, Rao said, companies may actually expand hiring because "there's no shortage of work to do." Still, Rao's description of the workplace inside Anthropic suggests the nature of white-collar work is already changing rapidly. He said employees increasingly oversee AI systems rather than completing tasks manually, while teams deploy "fleets of agents" that work across projects simultaneously. "Everyone kind of becomes a manager," Rao said. "The implications of that and the productivity gain that can come from that — we're very, very early in that, but the potential for it is incredible."

Cisco on Wednesday announced it would conduct layoffs affecting about 4,000 staff, or under 5% of its workforce. WEF Cisco plans to cut about 4,000 jobs to refocus on AI, affecting less than 5% of its workforce. Despite layoffs, Cisco sees strong quarterly results and raises sales forecast on AI demand. Cisco's restructuring will invest more in AI chips, fiber optics, and security amid job cuts. Cisco is cutting "fewer than 4,000 jobs" as the networking giant restructures its business to focus more heavily on artificial intelligence, according to a memo from CEO Chuck Robbins published Wednesday. The layoffs, which affect less than 5% of Cisco's workforce, come as the company reported stronger-than-expected quarterly results and raised its sales forecast on growing demand for AI infrastructure. In a regulatory filing on Wednesday, Cisco said the restructuring is expected to cost up to $1 billion, largely due to severance expenses. The company said it expects to record about $450 million of those charges in the current quarter, with the remaining costs carrying into fiscal 2027. The company's stock was up more than 17% in after-hours trading. Cisco joins a growing list of tech companies that have tied layoffs to AI-related efficiencies and broader organizational changes. In the memo, Robbins said Cisco is shifting investments toward areas "where demand and long-term value creation are strongest," including AI chips, fiber optics, and security. The company said it plans to continue hiring in strategic areas while eliminating some roles as part of its AI-related restructuring. Read the full memo below: Team, Today we announced our Q3 FY26 earnings with record revenue of $15.8 billion, up 12 percent year over year, and double-digit top and bottom-line growth. The ELT and I could not be prouder of the growth you have all delivered for Cisco. These results are even more impressive given the complex environment we're operating in — a rapidly changing market, with intensifying competition, and a global shortage of components critical to support our portfolio and the AI buildout from our customers. The companies that will win in the AI era will be those with focus, urgency, and the discipline to continuously shift investment toward the areas where demand and long-term value creation are strongest. I'm confident Cisco will be one of those winners. This means making hard decisions — about where we invest, how we're organized, and how our cost structure reflects the opportunity in front of us. With this, we are making changes today that will result in the reduction of our overall workforce in Q4 by fewer than 4,000 jobs, representing less than 5 percent of our total employee base. Most notifications will begin on May 14 and continue globally in alignment with applicable local laws and regulations. For employees whose roles are impacted, leaders will share details directly — including timing, available resources, support, and benefits in each country. This will include pro-rated payment of FY26 bonuses to impacted employees. We will provide support in finding new opportunities, whether internal or external, through Cisco's placement services — a program that has seen 75 percent of participants discover their next role. We are also committed to continued personalized learning and will provide one year of access to all Cisco U courses and certifications, covering AI, Security, Networking, and more. While we are reducing roles in some areas, we are making clear, strategic investments — particularly in silicon, optics, security, and in our employees' use of AI across the company. These investments are building from a position of strength — and focusing on the technologies and businesses that will accelerate our growth, deliver unmatched innovation to customers and partners, and define our future. To those leaving Cisco, thank you for your contribution, your dedication, and the mark you have made on this company. We are deeply grateful and are committed to handling this transition with the care, clarity, and respect that defines our culture. For those who will continue here, we will discuss these changes and answer questions at the Cisco Beat on May 21 at 8 a.m. PT. We have important, impactful, and consequential work ahead. Your focus, resilience, and leadership are vital to our growth and relevance in FY27 and beyond. Chuck and the Executive Leadership Team Read the original article on Business Insider

There are only six moves in this longevity-focused strength-training routine. Hilary Brueck, Business Insider Researchers are testing a new 6-move strength-training routine for healthy aging. The program doesn't require any weightlifting and can be adapted for any fitness level. People in the trial have been getting stronger and more nimble. Most longevity scientists and doctors agree that one habit is better than any drug or supplement for healthy aging: Exercise. Researchers are still piecing together exactly why exercise supports longevity. Still, it appears to benefit not only fitness and metabolism, but also improve how our cells operate. Plus, exercise lowers a person's risk of developing age-related diseases like cancer and dying early. It also boosts mental health. How do you exercise for longevity? In a groundbreaking clinical trial, researchers at Mount Sinai Hospital in New York City are trying to answer this question in a simple, straightforward way. They are testing a new home exercise routine for patients aged 60-85 that requires almost no equipment. I tried it while visiting the Mount Sinai Physiolab, where researchers measure how your body shifts from burning fat to carbohydrates for fuel as workout intensity increases. In the lab, we tracked how my body switched from fat burning to carbohydrates as fuel for exercise. Hilary Brueck, Business Insider During my visit, I learned the six foundational moves of their evidence-based strength training routine. These exercises are intended to support what aging researchers call "activities of daily living," which keep people independent and mobile as they get older. Moves like getting out of your chair, climbing stairs, and picking things up off the floor should get easier over time as you repeat these exercises. The goal in this longevity trial is for people to work up to three sets of 10, three times a week. The three lower body moves for longevity include squats — a trainer's favorite My longevity exercise session started with squats, a classic go-to strength-training move that targets the legs, lower back, and core. Deadlifts strengthen the lower back and the butt, which is great for countering low back pain and maintaining good posture as we age. Finally, the third lower body exercise was a lateral walk with a band around my upper calves. This sideways move targets the smaller glute muscles, the gluteus medius and gluteus minimus, which help improve balance and stability. Exercise scientist and cardiometabolic disease expert Ryan Walker, who directs the Human Metabolism and Physiology Lab at Mount Sinai, said in this trial, as his patients have gotten fitter, he's noticed they are also walking faster. A faster gait speed is consistently linked to healthier aging and less physical decline in older adults. Participants are also getting noticeably stronger, needing tougher resistance bands over time. This training technique is sometimes referred to as progressive overload, the concept of increasing resistance and repetitions over time to build muscle and power. "Some people in the study are doubling up bands because they've become too strong," he said. "It's actually working." The three upper-body moves include a modified push-up for any fitness level Time to move on up and strengthen the upper body. Bent-over rows were a challenging first move, targeting my back, core, and shoulders. This exercise is a perfect antidote for hunching over a screen all day. No wonder I felt the burn. Shoulder presses with bands are a safer alternative to jumping into free weights, Walker said. "A lot of people in their 60s and 70s have never really done a resistance training program, and a common mistake that trainers and coaches make is throwing them right into free weights," he said. "That's not only most likely not safe, but it certainly is not going to be sustainable and feasible for them in the long term." Colored bands with varying degrees of resistance allow study participants to progress on their own over time, without the hazards or hassle of heavy weights. By continually challenging themselves, participants can stimulate improvements in bone density, connective tissue strength, and heart health. The last strength exercise we did was a push-up; no band was needed here. This one really challenges your entire core, arms, chest, shoulders, abs, and even your heart muscles. There is no shame in elevating this move using a wall or a bench, or dropping to the knees for your presses. Resistance training like this is "critically important for everyone after 35 to 40 for maintaining strength and balance and mobility," Walker said. If the trial yields favorable results, he hopes it can lay the foundation for a longevity exercise routine that could be delivered to hospitals, nursing homes, and anyone who wants to improve their fitness, strength, and bone health as they age. "You can, at the very least, stop or slow that decline in muscle wasting and muscle loss that's seen with aging and older adults," he said. Read the original article on Business Insider

NBCUniversal is adding micro dramas from both Bravo and ReelShort. Charles Sykes/NBCUniversal via Getty Images Peacock is licensing 10 micro dramas from ReelShort. NBCUniversal's streamer had already announced it's adding two Bravo original micro dramas this summer. Hollywood is leaning into short-form video and micro dramas. Peacock is dipping its toe into micro dramas by teaming up with ReelShort, Business Insider has learned. NBCUniversal is bringing 10 micro dramas from category leader ReelShort to its flagship streamer's mobile app starting on Thursday, two people familiar with the initiative told Business Insider. The company confirmed the deal but didn't disclose terms. The Peacock-ReelShort deal is a short-term licensing arrangement that will precede a pair of Bravo original micro dramas arriving on Peacock this summer, said John Jelley, NBCUniversal's SVP of product and user experience for Peacock. "We have got a lot of confidence that doing more in the vertical video space is really good for our users and really good for Peacock," Jelley told Business Insider. Micro dramas are bite-sized soap operas known for their cliffhangers, and many have romantic-fantasy themes. NBCU "handpicked" the ReelShort micro dramas it's putting on Peacock, Jelley said. Those titles include "Fated To My Forbidden Alpha," "The Call Boy I Met In Paris," and "Baby, Just Say Yes!" a person familiar with the deal said. ReelShort, a privately held company, didn't respond to a request for comment. The Peacock parent unveiled its first two planned micro drama originals from Bravo this week at its annual presentation to ad buyers: "Campus Confidential: Miami" and "Salon Confessionals with Madison LeCroy." However, it didn't announce its ReelShort licensing deal at the time. Jelley said bringing ReelShort's micro dramas aboard temporarily will help NBCU "make sure that this new format — like all of our new formats that we're testing — really resonates with fans." "There's a lot of differences, subtle differences, between these different types of vertical video — how people click through, how long they stay, how they navigate — and we want to really understand that," Jelley said. Hollywood has become enamored with short-form vertical video, which increasingly dominates social media apps like TikTok and Instagram. YouTube Shorts have also gained popularity in the last few years. NBCU added vertical video clips to the Peacock mobile app last year, and in recent weeks, rivals Disney+, Netflix, and Paramount+ have followed suit. Peacock subscribers can now scroll through Bravo clips, sports highlights, and even AI-generated videos — including a digital avatar of Andy Cohen. These streamers hope that short-form video can help them boost engagement, especially among younger viewers. Read the original article on Business Insider

Amazon headquarters in Seattle Jason Redmond / AFP via Getty Images Amazon's Selling Partner Services team cut jobs this week. Amazon is doubling down on AI and other forms of automation. The latest job cuts highlight Amazon's ongoing efficiency drive. Amazon cut more jobs this week, with reductions hitting its Selling Partner Services organization this time, a company spokesperson confirmed to Business Insider. The layoffs follow roughly 30,000 job cuts announced across waves in October and January. In March, the company also eliminated a small number of roles in its robotics division. The size of the layoffs this week could not be determined, though the spokesperson described the cuts as affecting a "small number" of employees. "We regularly review our organizations to ensure we're best set up to deliver on our goals. Following a recent review, we've made the difficult decision to eliminate a relatively small number of roles in our Selling Partner Services team. We don't take decisions like this lightly, and we're committed to supporting affected employees with transitional health care, a separation payment, and outsourced job placement services," the spokesperson said in a statement. The Selling Partner Services group works closely with millions of third-party merchants that sell products on Amazon's marketplace, helping with onboarding, logistics, and account support. The latest cuts underscore how Amazon continues to reshape its sprawling retail organization after CEO Andy Jassy spent the last two years emphasizing efficiency and cost discipline. While the company previously framed large-scale layoffs as a response to pandemic-era over-expansion, the continued reductions suggest Amazon is still fine-tuning headcount across multiple businesses. The cuts also come as Amazon aggressively expands its investments in AI across nearly every part of the company, from retail operations and customer service to advertising and logistics. Executives have increasingly pushed teams to use AI tools to automate routine tasks and streamline operations, raising concern among some employees that roles might be replaced or reduced through automation. Jassy has said AI will allow Amazon to operate more efficiently over time, and warned last year that it could help "reduce" the company's workforce. Have a tip?
