Breaking AI & Tech News Analyzed

The Launch of Sesame's Conversational AI On Thursday, the AI startup Sesame, co-founded by Oculus' founders and others from the VR company that sold to Meta, released a public preview of the conversational AI agents it's been developing for over a year. With its new iOS app, Sesame is rethinking the traditional AI chatbot experience popularized by apps like ChatGPT, creating one where conversation flows, even if the AI needs time to think. Reimagining AI Conversation Flow As the company explains in its launch announcement, "There's an inherent tension between replying quickly and taking the time to compose thoughtful responses. A slower response is usually more correct, but it can also feel unnatural if it takes too long." To address this challenge, Sesame claims to have built fast search and retrieval systems, so the AI can have up-to-date information, as well as technology that allows it to run multiple parallel searches while speaking, weaving those results into its responses as it talks. That means the AI will talk more like a human, even pivoting mid-sentence if need be, as it taps into newer information — as a human might when remembering another key fact or point they want to add. User Growth and Development Milestones The app offers four distinct AI agents called Maya, Miles, Simone, and Charlie, each of which have their own distinct voice, personality, point of view, and memory. Maya and Miles were previously available in Sesame's Research Preview of its technology, where they were soon accessed by over one million people within the first few weeks, said Sesame investor Sequoia at the time. (The company had then just raised its $250 million Series B from Sequoia and others and was opening up a beta.) During the beta, Sesame learned from user feedback and rolled out features such as search cards with image results for visualizing concepts, notes for capturing takeaways, a texting mode for those times when speaking aloud is not an option, and support for deep dives where you can get more in-depth results. There's also a new incognito mode for private conversations, which allows the agents access to prior context but saves nothing to memory. Transforming the AI Landscape The app, however, is only the first step toward Sesame's bigger plans for AI involving intelligent eyewear, which the team expects to launch in 2027. Before that, the agents will also learn to do more than just think with you, Sesame hints, suggesting they'll later be able to take action on your behalf — hence why they're called "agents" in the first place, instead of just chatbots. That is potentially even more interesting, as working with agentic tools or apps today requires being able to prompt for what you need and have a specific idea of what you want to happen, and sometimes, even how it should happen. A conversational agent that you could talk to naturally could help you take the next steps, without you having to perfect the command you're giving it. The Road to AI-Powered Eyewear The iOS app is out today in 39 countries, and the full experience is free for the time being. However, there still may be a short waitlist at sign-up. An Android preview is coming in the future, the company says.

The Rise of Recursive Self-Improvement in AIThe word "recursion" is the latest buzzword in AI circles. Two separate startups have taken on the name, and many more have started referencing recursive self-improvement (RSI) in their roadmaps. Like AGI before it, RSI has become a three-letter byword for a cataclysmic AI takeoff – even if there's still a little disagreement about what it exactly means.In basic terms, RSI refers to an AI system that can continuously upgrade itself. Once AI systems can manage the upgrade cycle better than humans, the process can become a closed loop, limited only by the compute power they can access, and humans are no longer necessary or even helpful.Scary or not, that's a vision that a lot of AI labs are eager to chase.Key Players Pursuing Recursive SystemsEarlier this month, well-known AI researcher Richard Socher launched the aptly named Recursive Superintelligence with RSI as an explicit goal. "Our main focus is to build truly recursive, self-improving superintelligence at scale," Socher told TechCrunch at launch, "which means that the entire process of ideation, implementation, and validation of research ideas would be automatic."A number of other prominent researchers are already chasing that same goal, hoping for a breakthrough that will make recursive self-improvement possible.One of the most prominent is Andrej Karpathy, a legendary figure from Tesla and OpenAI, who is using agent swarms to train LLMs on simple tasks for a project he calls Auto-Research. Karpathy has been unusually open about the project, tweeting about milestones regularly and making the building blocks available through a public GitHub repo. So far, the work has mostly been confined to making minor improvements on a GPT-2 scale model — as Karpathy noted in March, "It's not novel, ground-breaking 'research' (yet)" — but it's been enough to convince lots of other researchers to follow the RSI dream. And with Karpathy now working on pre-training at Anthropic, he will have plenty of opportunity to apply the idea at a larger scale.Adaption — founded by Cohere and Google alum Sara Hooker — recently launched a similar tool called AutoScientist in an effort to automate frontier training. Like Karpathy's auto-researchers, the system trains agents to make incremental improvements — but for Adaption, the goal is to make it easier to train a full-scale frontier model. If those same researchers start to push the frontier forward, the system could quickly spiral into something very much like RSI.Disarray founder Doris Xin drew more specific RSI interest when her self-trained machine learning agent took home 28 medals in a recent Kaggle competition, beating out many human-trained agents. As she sees it, the major challenge is reliability."I would argue, given infinite compute and infinite time horizon, we are already there," Xin told me. "I want to make an argument that this is not a creative endeavor, really. It's just a lot of meat-and-potatoes engineering."The Current State of Self-Improving AIThere's also plenty of evidence that the AI industry isn't very close to recursive systems in any meaningful way — and is still grappling with talking to a wary public about its progress. So Google CEO Sundar Pichai basically admitted in a recent podcast interview."It's a continuum, and we are all definitely making progress," Pichai said. "But in the way people describe RSI, that would represent a next level of acceleration and would have a lot of implications, but we aren't quite there yet."But the continuum includes an awful lot of self-improving AI systems.In January, one of Anthropic's lead programmers for Claude Code estimated that "close to 100%" of his team's code was written by the tool — a frank admission that Claude Code was literally writing itself.Just because engineers are using an AI tool doesn't mean the tool can replace them — but Anthropic seems to be getting close to replacing engineers too. In a recent survey tied to the Mythos preview, five out of 18 Anthropic engineers believed that, with harness improvements, this version of Mythos could soon substitute for an L4 engineer — a midlevel programmer who can take on involved projects without supervision.Still, there were some of the same weaknesses you might expect."Some of Claude's major reported weaknesses compared to an L4 include: self-managing week-long ambiguous tasks, understanding org priorities, taste, verification, instruction-following, and epistemics," the report reads.In other words, its weaknesses are everything involved with self-direction, which is the cornerstone for RSI. But sure, for everything else, Claude is ready to step right in.Expert Perspectives on RSI TimelinesJust like the AGI term before it, the AI industry also can't tell us how far away it is from showcasing a meaningful recursive system. When Georgetown's Center for Security and Emerging Technology assembled a group of experts to study RSI last year, the group found a major split in assessments — some expecting an imminent "superintelligence" style explosion while others expected slower progress and an eventual plateau. But all agreed that recursion made the future especially difficult to predict.Helen Toner, director of CSET and a former board member at OpenAI, told TechCrunch that simply using AI tools to do AI research isn't enough to qualify as RSI. "They're just using AI for as much as they can," Toner told TechCrunch. "And I think that is different from the classic definition of RSI, which is really that there are no humans needed."Toner pointed to a recent post by METR's Ajeya Cotra, which distinguishes different milestones on the path to the AI research takeover. One step, which Cotra calls "adequacy," would come when the system can still perform research after all humans are removed — even if the resulting research isn't as valuable or efficient. "Parity" comes when an AI-only system is as good at research as a human-only system. "Supremacy," the final stage, comes when an AI-only system outperforms a collaborative system between humans and AI.Ultimately, Cotra concludes that AI is very close to the adequacy threshold of being able to produce some work on its own — similar to the incremental changes made by Karpathy's Auto-Research system. "I wouldn't be totally shocked if you told me this milestone had already passed, and I expect it to happen in the next couple years," Cotra wrote.She was less clear on when parity will come, but once it does, she thinks it would "massively accelerate the pace of AI progress, leading to AI research supremacy within another year."The Challenges Ahead for Recursive AIWith so much of AI built on scaling laws, there's a strong tendency to think RSI will follow the same curve. Toner thinks that many of those pursuing AI research and development via RSI "think of it as a pretty smooth ladder, where you can just keep scaling up."But even if AI researchers are able to make incremental improvements like Karpathy's auto-researchers, there will be larger challenges in handing off the whole process of research. Toner put it in terms of the history of computing, which has seen human beings handing off more and more of the process while still directing things from the top."We went from machine languages to assembly language and compiled languages; you're getting further and further from the guts of the computer," Toner said. "But the human is still, in some intuitive sense, running the show."Moving beyond that paradigm will take significant challenges, both in engineering and alignment. But even with the massive investments happening, there's no infinite compute available — and the basic trade-off between human labor and machine intelligence will be hard to overcome.The Future of Recursive Self-ImprovementAs for a total recursive AI system of apocalyptic visions? The only thing researchers essentially agree on is that, like AGI, it's not here yet.

Visa has disclosed an undisclosed investment in AI coding platform Replit, aiming to embed its payment suite directly into the developer environment so that both developers and AI agents can accept payments without leaving the platform. Strategic Investment and Joint Exploration of AI‑Powered Payments The two companies are testing how Visa Intelligent Commerce and the Trusted Agent Protocol can be woven into Replit’s workflow. More than 1,000 Visa employees already use Replit for prototyping, and the collaboration remains in an exploratory stage with no formal product announcements. Valuation Surge and Funding Milestones Highlight Replit’s Growth September 2025: Replit reached a $3 billion valuation. March 2026: Raised $400 million in a Series D led by Georgian Partners, pushing valuation to $9 billion. Enterprise self‑serve contracts now allow deals up to $200,000 without sales interaction. Customer churn is described as "very, very low" with net retention hitting 300 % in some cases. Implications for the Emerging Agentic Payments Ecosystem The move underscores a broader race to build infrastructure for "agentic payments," where AI agents transact on behalf of users. Competitors such as Robinhood (agent‑driven trading) and Google (shopping agents) are pursuing similar capabilities, suggesting the market will soon demand secure, verifiable AI‑mediated transactions. Future Trajectory: From Prototype to Mainstream Agentic Commerce If the exploratory projects mature, Replit could become a one‑stop shop for developers to build, host, and monetize AI agents, accelerating adoption of Visa’s Trusted Agent Protocol. Analysts anticipate that as enterprise adoption grows and churn remains low, the partnership may evolve into a commercial product suite within the next 12‑18 months, positioning Visa and Replit at the forefront of the next wave of AI‑driven commerce.

Lead: Brazil’s 2026 World Cup outlook Brazil enter the 2026 FIFA World Cup as the most decorated nation with five titles, yet they have not lifted the trophy in 24 years. Under new manager Carlo Ancelotti, the squad blends seasoned stars such as Neymar and emerging talents like Vinicius Jr as they aim to defy low expectations. Ancelotti’s foreign‑manager milestone and tactical shift After dismissing Dorival Jr, Brazil appointed Carlo Ancelotti – the nation’s first permanent foreign coach. The Italian brings five Champions League crowns and experience across Europe’s top five leagues, promising a pragmatic yet attacking approach. Ancelotti has already repositioned Vinicius Jr as a central striker and reinstated Neymar despite recent injury concerns. Key statistics and squad composition World Cup appearances: 22 (every tournament since 1930) Best performance: Winners (1958, 1962, 1970, 1994, 2002) FIFA ranking: 6 Top scorer: Ronaldo – 15 goals Most caps: Cafu – 20 matches Player to watch: Vinicius Jr Squad highlights: Goalkeepers: Alisson, Ederson, Weverton Defenders: Marquinhos, Alex Sandro, Danilo, Gabriel Magalhães Midfielders: Bruno Guimarães, Casemiro, Fabinho Forwards: Vinicius Jr, Neymar, Raphinha, Endrick Why Brazil’s underdog narrative could reshape the tournament Despite a star‑laden roster, Brazil are among the least fancied Brazilian sides ever, a status that may relieve pressure and allow creative freedom. The blend of experienced leaders and youthful vigor, combined with Ancelotti’s proven ability to manage egos, could make Brazil a surprise contender against groups that include Morocco, Scotland and debutants Haiti. Outlook and Al Jazeera’s projection Al Jazeera predicts Brazil will reach the quarter‑finals. Their success will hinge on the fitness of Neymar, the form of Vinicius Jr, and the defensive stability provided by Marquinhos and Alisson. If the squad clicks, a deep run is plausible; otherwise, early knockout looms. Group C schedule June 13 – Brazil vs Morocco (East Rutherford, New Jersey) – 18:00 local / 22:00 GMT June 19 – Brazil vs Haiti (Philadelphia) – 21:30 local / 01:30 GMT (June 20) June 24 – Scotland vs Brazil (Miami) – 18:00 local / 22:00 GMT

The LeadA novel featuring a protagonist whose job is taken by AI has won the Climate fiction prize. Hum by Helen Phillips, the American writer's third novel, explores themes of technological displacement and the commodification of nature in a dystopian future.The Disneyfication of Nature in LiteratureHum is about a woman, May, who loses her job to a "hum" of the title – a humanoid robot. Struggling to find work, she becomes a guinea pig for an experimental injection that alters her face so it can't be recognised by surveillance. When she gets paid for it, she splashes out on family passes to the Botanical Garden, the last remaining green space in her city. There, things take a turn for the worse.The Climate Fiction Prize RecognitionThe prize, worth £10,000, was first awarded last year to Abi Daré for And So I Roar, the follow-up to her bestselling debut The Girl with the Louding Voice. This year's judging panel was chaired by Guardian theatre critic and former literary editor of the Independent, Arifa Akbar. Alongside Kit de Waal and Friederike Otto on the panel were author Jessie Greengrass and book influencer Simon Savidge.Judges' Perspectives on the NovelJudge and writer Kit de Waal described Phillips's book as being about the "Disneyfication of nature … turning nature into a rare place that we have to pay to see". Fellow judge and climate scientist Friederike Otto added that it "tackles the central reason that nothing is done about the climate crisis – privilege", while writer Daisy Hildyard described it as "mesmerising and scary".The Author's InspirationPhillips was inspired to write the book after walking home from work one day and having the thought that she needed to buy dishcloths, before opening her computer at home and finding that dishcloths were being advertised to her. "That eerie feeling stuck with me, and I started to think about what worst-case scenarios might arise from surveillance by an algorithm."Impact on Climate AwarenessHum "helps us connect with what really matters and stops us from sleepwalking into an inevitable dystopia", said Lucy Stone, CEO of Climate Spring, which funds the prize. "In the novel, the machines themselves start to question the insane volume of advertising and the consumer treadmill, and then show the family that there are multiple different futures lying ahead of them."Future RecognitionPhillips will appear at Hay festival to discuss the book on Saturday 30 May. Alongside Phillips on this year's shortlist were Madeleine Thien for The Book of Records, Robbie Arnott for Dusk, Keshava Guha for The Tiger's Share, Susanna Kwan for Awake in the Floating City and Maria Reva for Endling.

The Comeback That Almost WasBritish No 4 Fran Jones delivered a performance defined by sheer grit, pushing 27th seed Marie Bouzkova to the brink of defeat in a high-stakes second-round clash at Roland Garros. Despite trailing 0-6 in the first set and 1-4 in the second, Jones refused to surrender, eventually falling 6-0, 7-6 (3). The match served as a testament to her resilience, as she fought back from a seemingly insurmountable deficit to force a tie-break.Deconstructing the Match DataRanking Disparity: Jones, ranked outside the world's top 100, faced a significant challenge against Bouzkova, a former top-10 player and consistent tour veteran.Scoreline Analysis: The 6-0, 7-6 (3) scoreline highlights a dominant first set followed by a gritty recovery in the second.Turning Point: Jones led the second-set tie-break 3-1, demonstrating her ability to compete at the highest level even when physically compromised.The Impact of Mental FortitudeWhat defines Jones is not just her heavy topspin forehand, but her "mentality monster" persona. Having overcome a rare genetic condition (ectrodactyly) and recent physical setbacks like a glute tear and concussion, her ability to maintain focus under extreme pressure is her unique selling point. Bouzkova, often described as a "gatekeeper" due to her durability, proved too consistent in the end, but Jones forced her to work for every point.Looking Ahead: The Road to WimbledonDespite the loss, Jones views this week as a stepping stone. With her sights set on the grass-court season, her confidence in her mental approach suggests she will continue to climb the rankings. Her primary focus now shifts to physical recovery and maintaining her fitness to capitalize on her formidable mindset when the tournament moves to Wimbledon.

The Lead: China's Bold Leap into Long-Duration SpaceflightChina has launched its Shenzhou-23 mission in which an astronaut will spend a full year in orbit for the first time, a crucial step in Beijing's ambition to send humans to the moon by 2030. The Long March 2-F rocket lifted off from the Jiuquan launch centre in north-western China on Sunday, carrying three astronauts to the Tiangong space station.The Mission Details: Historic Crew CompositionThe mission marks the first spaceflight ever undertaken by an astronaut from Hong Kong: Lai Ka-ying, 43, who previously worked for the territory's police. The other crew members are the space engineer Zhu Yangzhu, 39, and the former air force pilot Zhang Zhiyuan, also 39, who will be travelling into space for the first time.The Scientific Objectives: Preparing for Deep SpaceThe crew is expected to undertake numerous scientific projects in life sciences, materials science, fluid physics and medicine. A key experiment will be the full-year stay in orbit by one of the crew to study the effects of a long stay in microgravity, part of China's preparations for future lunar and possible Martian missions.Richard de Grijs, an astrophysicist and professor at Macquarie University in Australia, said the main challenges would be long-term effects on humans, including bone density loss, muscle wasting, radiation exposure, sleep disturbance and behavioural and psychological fatigue. He also underlined the importance of reliable water and air-recycling systems and the ability to manage potential medical emergencies far from Earth.The Lunar Ambitions: China's Moon RoadmapThe Shenzhou-23 mission is part of China's goal to land astronauts on the moon before 2030 in a race with Nasa's Artemis programme. Beijing is also testing the equipment required to reach its goal, with an orbital test flight of its Mengzhou spacecraft set for 2026. It will replace the ageing Shenzhou line and will carry China's astronauts to the moon.China hopes to have built the first phase of a manned scientific base, known as the International Lunar Research Station, by 2035. It also plans to welcome its first foreign astronaut, from Pakistan, to the Tiangong station by the end of this year.The Global Context: China's Space Program EvolutionBeijing has significantly expanded its space programmes over the last 30 years, injecting billions of dollars in a push to catch up with the US, Russia and Europe. It landed the Chang'e-4 probe on the far side of the moon, a world first, in 2019, and a rover on Mars in 2021.China has been formally excluded from the International Space Station since 2011, when the US banned Nasa from collaborating with Beijing, prompting it to develop its own space station project. This isolation has accelerated China's indigenous space capabilities, making the Shenzhou-23 mission a milestone in both scientific achievement and geopolitical space competition.

The Urban Pompeii of Los AngelesThe La Brea Tar Pits and Museum, a cornerstone of Los Angeles' cultural landscape, is preparing to close its doors in July 2026 for a comprehensive overhaul. This $240 million renovation aims to reimagine the visitor experience while preserving the site's status as the world's only urban, active ice age excavation site.A $240M Transformation of the Ice AgeThe project, led by the Natural History Museums of Los Angeles County and designed by the New York firm Weiss/Manfredi, will transform the interior exhibition spaces and the surrounding 13-acre park. New walkways and bridges are planned to create a dynamic environment, though the existing structure will remain largely intact.Project Timeline: Closing in July 2026, reopening in 2028.Design Firm: Weiss/Manfredi (known for Brooklyn Botanic Garden and Olympic Sculpture Park).Scope: Interior updates, landscape features, and new bridges.Preserving the Past: The Value of the CollectionThe site holds over 2 million fossils, including mastodons and saber-toothed cats. The preservation quality is exceptional, retaining collagen for accurate carbon dating, which provides invaluable data on the past ecosystem. The site is often described as "Pompeii, but in the middle of a massive city."Bridging the Gap Between Science and SocietyEmily Lindsey, the museum's associate curator, emphasizes the site's critical role in scientific literacy. It offers a unique opportunity to showcase the scientific process publicly, countering current mistrust of science by making it accessible and understandable to the public.The Future of Urban PaleontologyThe reopening in 2028 is expected to set a new standard for urban natural history museums, potentially increasing attendance and serving as a model for integrating scientific research directly into public spaces.
