Three Swiss men aged 28, 43 and 52 were wounded in a stabbing at the Winterthur train station on Thursday morning (08:30 local time). Police identified the attacker as a 31‑year‑old Swiss‑Turkish dual national and classified the incident as an “act of terror”.Stabbing at Winterthur Train Station Classified as Terrorist ActRegional police chief Marius Weyermann confirmed the suspect was arrested five minutes after emergency services were alerted. The man had previously attracted police attention in 2015 for distributing ISIL propaganda and had been briefly placed in a psychiatric facility days earlier.Casualties and Immediate ResponseVictims: ages 28, 43, 52Two victims discharged or set for release by mid‑afternoonOldest victim remains hospitalized after thigh surgeryArrest made within five minutes of the attackSecurity Implications for SwitzerlandZurich’s top security official Mario Fehr described the incident as “an evil act of terror”. Swiss President Guy Parmelin expressed shock, emphasizing the deep impact on the nation. The Islamic Central Council of Switzerland condemned the attack and reiterated that ISIL is a perverse terrorist sect, not an Islamic movement.Potential Policy and Community Reactions AheadAuthorities believe the attacker acted alone, but the incident may prompt tighter monitoring of individuals with extremist links and renewed debate on mental‑health assessments in security contexts. Community leaders are expected to call for solidarity and increased vigilance in public spaces.

Asana's Strategic AI AcquisitionAsana has acquired the workflow automation company StackAI for $75 million, marking a significant step in the company's broader AI pivot. The acquisition aims to position Asana as an "AI-native workplace platform" and integrate StackAI's agent-building capabilities into Asana's existing work management system. The announcement was made Thursday afternoon to coincide with Asana's earnings and investor call.StackAI's Workflow Automation CapabilitiesStackAI, built as an AI workflow-automation system, designs agents to operate within existing business systems, pulling in data from platforms like Salesforce, Slack, and Gsuite. The company, founded by Tony Rosinol and Bernard Aceituno, will join Asana as part of the acquisition. StackAI has faced competition from automation tools like Zapier as well as AI labs like OpenAI and Anthropic in the rapidly evolving AI automation space.Financial Terms and Funding BackgroundThe acquisition comes as StackAI had raised just under $20 million, according to PitchBook data, with most of it coming in a recent $16 million Series A round. That round included funding from Gradient, Epakon Capital, Lobby VC, LifeX Ventures, and Vercel CEO Guillermo Rauch. While the $75 million acquisition price represents a significant premium over StackAI's funding, it reflects Asana's commitment to accelerating its AI capabilities.Asana's AI-Native TransformationWhile users are most familiar with Asana's work management system, the company has been releasing AI-oriented products in recent years, including the AI Studio agent builder and AI Teammates series of pre-built automations. Asana believes its deep integration into existing corporate workflows provides a key advantage, allowing it to distill context and training data that would otherwise be unavailable. This acquisition specifically aims to "agentify the most complex business processes end-to-end," according to CEO Dan Rogers.Future of Human-Agent Work in EnterpriseAsana has struggled on public markets during the AI era, losing more than half its market cap value since the introduction of ChatGPT. However, revenue has continued to grow steadily, and the new leadership is confident that human-agent products will enable a rebound. With this acquisition, Asana aims to accelerate its roadmap into "the next phase of human-agent work," potentially differentiating itself from both traditional work management platforms and standalone AI automation tools in the competitive enterprise software landscape.

The Munition Shortage The United States has enough munitions for any plausible scenario in the Iran war, but rebuilding its depleted inventories will “take years”, according to a new report by the Center for Strategic and International Studies (CSIS). Replenishment Timeline Restoring pre-war stockpiles of four critical munitions heavily used by US forces during nearly 40 days of joint fighting with Israel against Iran would take at least two years – and in some cases more than three – the Washington-based think tank said on Wednesday. Land Attack Missile (TLAM) Terminal High Altitude Area Defences (THAAD) interceptors Patriot missiles SM-3 and SM-6 ship-based surface-to-air missiles The Data Analysis The report noted that while US officials publicly project confidence in weapons stockpiles, analysts have said that dwindling munition supplies may be shaping Washington’s calculations over whether to resume the war on Iran. The Impact Analysis “Campaigns against Iran and its proxies – and, for Patriot interceptors, aid to Ukraine – have made the problem more acute,” said the CSIS report. “Alongside replenishing its own stocks, the United States also has to fulfil orders from allies and partners.” The Prediction “Decisions on how to allocate new production have already created bilateral friction, and this friction will continue for the next few years as demand outpaces supply,” the report warned. The main problem is not funding but production time, limited manufacturing capacity and long procurement lead times, with CSIS noting that past procurement levels were relatively low for many systems, slowing replacement efforts despite recent increases in defence spending.

The Lease Duration Dispute A controversy has arisen regarding the length of Anthropic's lease with SpaceX, a deal that involves billions of dollars a month for exclusive use of Anthropic's Colossus cluster. Elon Musk claimed on X that the lease is for 180 days with a 90-day notice for mutual cancellation, while SpaceX's recent S-1 filing presents the deal as a three-year agreement. The Details of the Deal According to Musk, the short-term lease was SpaceX's request, not Anthropic's. He stated that SpaceX won't leave Anthropic hanging and will provide a reasonable off-ramp, but might need the compute capacity back if it gets super tight. On the other hand, SpaceX's S-1 filing confirms a 90-day cancellation notice but describes the agreement as lasting through May 2029, with a monthly fee. The Data Analysis The deal involves a significant monthly fee of $1.25 billion, as mentioned in the S-1 filing. This substantial commitment highlights the importance of the compute capacity for both parties. The Impact Analysis The discrepancy between Musk's statement and SpaceX's filing raises questions about the accuracy of the information provided. This situation could be seen as a material misrepresentation made while marketing a security, which could have implications for investors and the companies involved. The Prediction The future of the lease and the relationship between Anthropic and SpaceX will depend on how this situation unfolds. With the SEC possibly involved, the companies will need to clarify the terms of the agreement to avoid any further controversy.

The Road to Wembley Wigan Warriors are gearing up for a big presence at Wembley as they compete in the Challenge Cup finals on Saturday. The club has selected two players, Liam Farrell and Jenna Foubister, to represent them at a Wembley photoshoot, showcasing the team's strong squad and dedication to the sport. Wigan's Successful History Wigan have a remarkable record in finals, rarely losing two on the bounce. With 21 Challenge Cups under their belt, the team is driven by a strong mentality and a rich history of success. According to Farrell, 'There's a bit of outside pressure, an expectation from fans in the town to win. There's also a strong mentality at the club of Wigan lads, who have grown up watching us win finals, wanting to reproduce that themselves.' The Next Generation The club's academy graduates account for 20% of all Super League players, demonstrating Wigan's commitment to developing young talent. Foubister, a 19-year-old player, has already made her England debut and won the quadruple, highlighting the club's ability to nurture and support its players. 'The club put a lot into the youth system,' she says. 'They are very supportive in the way they shape players for the future.' A New Era for Women's Rugby Wigan have taken a proactive approach to providing for their female players, with the women's team having sole use of the revamped Edge Hall Road site. This move has helped to increase the team's fanbase and provide a platform for players like Foubister to develop their skills. 'It is a privilege having our own ground,' she says. 'We can go up whenever we want and have the freedom to train, whereas at Robin Park you got slotted in at a certain time.' Building a Legacy As Farrell's career enters its final phase, Foubister aims to become a hero in her hometown and build a legacy for the women's team. 'The men have a lot of history behind them, but the women's team has to build a history of our own now,' she says. With the support of the town and the club, Foubister and her teammates are well on their way to achieving their goals.

The US Strikes on Bandar Abbas The United States has carried out strikes near Bandar Abbas, the second attack in less than a week on Iran’s strategically important port city, escalating tensions around the Strait of Hormuz despite a fragile ceasefire that has been in place between Washington and Tehran since April 8. Details of the Attack Reuters and The Associated Press, quoting unnamed US officials, reported that US forces shot down four Iranian drones and struck a ground control station for drones on Wednesday in Bandar Abbas. The strikes followed explosions in Bandar Abbas on Tuesday. Iran’s Ministry of Foreign Affairs accused Washington of violating the ceasefire through “aggressive acts” in Hormozgan province, where the port city is located. Significance of Bandar Abbas Bandar Abbas, home to key Iranian naval forces, occupies one of the most strategically sensitive positions in the Gulf. Its location on the Strait of Hormuz has made it central to both Iran’s military position and the wider confrontation with the US. Bandar Abbas lies on Iran’s southern coast, on the northern side of the Strait of Hormuz, the narrow waterway linking the Gulf to the Gulf of Oman and Arabian Sea. The city had a population of more than 526,000 people at the time of Iran’s 2016 census. Military Significance Bandar Abbas is the headquarters of both Iran’s conventional navy and the naval arm of the Islamic Revolutionary Guard Corps (IRGC). The conventional navy has used it as its base since 1977 when Iran moved much of its fleet from Khorramshahr at the western edge of Iran’s Gulf coastline, to Bandar Abbas, transforming the city into the country’s main southern naval command centre. According to the Middle East Institute, the IRGC navy later relocated its headquarters from Tehran to Bandar Abbas to improve operational control along the Strait of Hormuz. Economic Importance The Strait of Hormuz is not just a military chokepoint but also an economic lifeline. Analysts estimated that more than 90 percent of Iranian crude shipments transit through the strait. That makes Bandar Abbas and nearby Gulf infrastructure critical to government revenues, including the trade networks that help Iran circumvent sanctions, particularly by exporting oil to China. Impact on Peace Negotiations Diplomatic and military operations are unfolding simultaneously as Iran and the US have exchanged a volley of proposals and counterproposals for peace since the ceasefire began. “This is unfolding on parallel tracks. There is a military track and a negotiating track all unfolding at the same time,” said Samir Puri, a visiting lecturer in war studies at King’s College London. “The negotiators can only present the leverage they have from the field of battle.

Apple's AI-Powered Siri App Set to Rival ChatGPT Apple is planning to unveil a new AI-powered Siri app at its Worldwide Developers Conference (WWDC) in June, according to leaked renders published by Bloomberg. The app is designed to rival popular AI chatbots like ChatGPT, Claude, and Gemini. The New Siri App Features The new Siri app will feature a rebuilt AI model that uses Google's Gemini AI technology under the hood for added intelligence. The app will allow users to search, launch apps, start messages, ask about the weather, add calendar appointments, search their notes, and trigger app shortcuts. Results will be displayed in a formatted text in a card-style interface that emerges from the iPhone's Dynamic Island. The Data Analysis 2.5 billion: Apple's install base across all devices 900 million: Weekly active users of ChatGPT The Impact Analysis Apple's approach to AI is similar to its earlier multibillion-dollar partnership with Google that made Google the default search engine on iPhone. By partnering with outside companies for AI technology, Apple can leverage its scale and unmatched runway to introduce AI to people who haven't yet adopted standalone AI tools. The Prediction With its massive install base and reputation for prioritizing user privacy, Apple is well-positioned to make a significant impact in the AI market. The new Siri app and AI-powered features are expected to be a major part of Apple's strategy to compete with popular AI chatbots and establish itself as a leader in the AI space.

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.

The Tactical Chess Match of Champions League FinalIt would be easy to look at Saturday's Champions League final between Paris Saint-Germain and Arsenal and see it as a battle of attack versus defence, of beauty against pragmatism, of French elan against English doughtiness, as some sort of tussle for the soul of football. But it would not entirely be true. And where, after all, was the honour at Agincourt? In the vainglorious charges of the dashing French cavalry or the stoic defiance of the British archers arrayed, naked from the waist down, behind their defensive stakes?The final promises to be a fascinating tactical contest between two teams with contrasting approaches but complementary strengths. PSG's devastating wings, featuring players like Desiré Doué and Khvicha Kvaratskhelia, will test Arsenal's defensive resolve, while Arsenal's set-piece prowess could provide their route to goal.PSG's Dominant Possession vs Arsenal's Defensive ResilienceThe statistical comparison between the two teams reveals contrasting strengths. In the Champions League this season, Paris Saint-Germain have averaged 63.4% possession, higher than anybody apart from Barcelona; Arsenal's figure is 52.6%, the 11th-highest of the 36 sides who made the league stage. PSG's pass completion has been 89.3% to Arsenal's 85.7% (third-highest to 14th-highest). PSG have scored 44 goals to Arsenal's 29. But on the flip side, Arsenal have conceded six goals to PSG's 22 and won 13.4 aerial duels per game to PSG's 9.4 (sixth-highest to 29th-highest).These figures suggest that PSG will dominate possession, while Arsenal will likely sit deep and look to counter-attack. However, that was not how either leg of the semi-final between the teams last season played out: PSG shaded possession at the Emirates and Arsenal at the Parc des Princes as they chased the game.The Full-Back Dilemma for ArsenalThe biggest danger to Arsenal is probably a counterattack. Most opponents sit deep against PSG, especially in Ligue 1, but the evidence of PSG's wins over Chelsea, Liverpool and Bayern Munich is that they are lethal in transition. Arsenal cannot let Desiré Doué or Khvicha Kvaratskhelia get a run on whoever they have at full-back. Both are rapid, supreme dribblers and terrifyingly direct.Full-back is an issue for Arsenal, especially on the right. Ben White is out with a knee injury and Jurriën Timber is doubtful with a groin problem sustained against Everton in mid-March. Martín Zubimendi started at right-back against Crystal Palace but it would seem more likely that Cristhian Mosquera operates there if Timber has not recovered, if only because he is a more natural defender.Riccardo Calafiori has seemed Mikel Arteta's preferred option on the left. His role will be twofold: to stop Doué and to invert into midfield, particularly out of possession, to try to prevent the counter. It may be that Myles Lewis-Skelly is used ahead of Zubimendi alongside Rice, in part because he is familiar with playing at left-back and so could help double up on Doué, or would be comfortable covering for Calafiori were he caught upfield.Midfield Strategies to Counter PSG's WingsAlthough PSG have scored more goals from non-penalty set plays than Arsenal in the Champions League this season (eight to five), it probably is reasonable to assume that corners and free-kicks offer Arsenal's best chance of a goal. But to counter PSG's midfield dominance, Arsenal may need to embrace a more aggressive approach.The first leg of PSG's semi-final against Bayern was remarkably open, almost basketball-like in its end-to-end attacking. But that should not necessarily be regarded as characteristic. PSG can at times seem a little sloppy, too reliant on their attacking prowess, but their performance away to Bayern, when Fabián Ruiz returned, showed how effective PSG's midfield can be. And that means either that Arsenal have to sit deep and accept PSG will dominate the ball or that they need to ensure their midfield has a destructive edge.Lessons from Previous EncountersChelsea's success against PSG in the Club World Cup final perhaps offers, if not a template, then at least inspiration for how Arsenal can hurt the defending European Champions. Enzo Maresca's approach was asymmetric, using Cole Palmer almost as an inside-right, haunting the channel between Nuno Mendes and the left-sided centre-back while getting in behind the left-back wherever possible.On the left, Marc Cucurella regularly tucked into midfield, just as Calafiori surely will, with Pedro Neto tracking back almost as a wing-back to check Achraf Hakimi's thrusts in support of Doué. If Arteta sees things similarly, that is probably more of a job for Leandro Trossard than Eberechi Eze, who may end up on the bench if Arteta, as he surely must, prefers 4-3-3 to 4-2-3-1.Keys to Victory in Saturday's FinalThere is an irony in this. The stereotype of Arsenal this season has been of a defensive side reliant on set plays, but that is not entirely accurate; rather they are a side whose defensive qualities have been highlighted because of deficiencies of creativity and attacking quality. But to beat PSG, it may be that they have to embrace the narrative and be the side critics say they are.Arsenal's right-back situation remains critical. White links better with Bukayo Saka than any of Arsenal's other full-backs, and Timber is as tactically astute as any player in the squad. Unless Timber is fit, the right-back issue is likely to diminish them from a defensive and an attacking point of view.The final will come down to which team can impose their tactical approach most effectively. Can Arsenal's defense contain PSG's devastating wings, or will PSG's midfield dominance prove too much for Arsenal to handle? The answer will determine who lifts the Champions League trophy on Saturday.
