Breaking AI & Tech News Analyzed

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 United Nations' weather agency has warned that the planet is on track to experience its hottest year on record by the end of the decade, with climate risks intensifying across the globe.WMO Forecast Signals 86% Likelihood of New Hottest Year Within Five YearsIn a report released on Thursday, the World Meteorological Organization (WMO) stated there is an 86% chance that one of the next five years will surpass 2024 as the warmest year since records began. The agency also highlighted a 75% probability that the five‑year average temperature from 2026 to 2030 will exceed the 1.5 °C increase above pre‑industrial levels.Statistical Outlook: Probabilities, Temperature Gaps, and Regional Shifts86% chance of a new record year within the next five years.75% chance that the 2026‑2030 average exceeds 1.5 °C (2.7 °F) above pre‑industrial levels.Arctic winter temperatures projected to be 2.8 °C (5 °F) above the 1991‑2020 average, more than three‑and‑a‑half times the global rate.Rainfall expected to rise in the Sahel, Northern Europe, Alaska and Siberia, while the Amazon is forecast to become drier.Implications for the Paris Agreement and Global Climate PolicyAlmost 200 countries signed the Paris Agreement in 2016, pledging to limit warming to 1.5 °C. The WMO’s findings suggest the target is becoming increasingly unattainable unless emissions are cut dramatically. Michael Jacobs, professor of political economy at the University of Sheffield, warned that nations must accelerate renewable‑energy deployment and electrification. Simon Stiell, the UN climate chief, called recent European heatwaves a “brutal reminder” of the stakes.Looking Ahead: What 2030 Could Mean for Extreme Weather and Mitigation EffortsIf the projected trends materialise, the world can expect more frequent and intense heatwaves, stronger storms, and heightened stress on water resources. Policymakers will face pressure to tighten emissions‑reduction commitments, expand climate‑resilient infrastructure, and secure financing for adaptation in vulnerable regions. The next five years will be a decisive window for translating climate pledges into concrete action before the 2030 temperature threshold is crossed.

The Economic Dilemma Facing Jamaica's Energy Future Jamaica stands at a critical juncture in its energy policy, with preliminary tests off the south coast suggesting the presence of crude oil in the Walton-Morant basin. This potential discovery comes at a time when the island is grappling with the dual pressures of post-pandemic recovery and the escalating costs of climate adaptation. Testing the Waters in the Walton-Morant Basin United Oil & Gas, a UK-based company, holds the exclusive exploration license for the 22,400sq km block. Recent seabed sampling has identified hydrocarbons, a development that energy minister Daryl Vaz has described as "very positive." However, experts caution that even with confirmation, commercial production is unlikely until the mid-2030s. Balancing the Books: Fuel Imports vs. Climate Costs The financial calculus behind this potential shift is stark. Jamaica currently imports all its fuel, a cost that fluctuates between $1.5bn and $2bn annually. While the island generated $4.3bn from tourism in 2024, the economic strain is compounded by the $12bn bill for damage caused by Hurricane Melissa. This financial vulnerability is driving the government's cautious optimism toward oil exploration. The Regional Race for Fossil Fuels Jamaica is not alone in this pursuit. The Caribbean and Latin America are witnessing a resurgence in fossil fuel interest, following Brazil's deep-water discoveries in the 2000s. The region is now joined by Suriname and Guyana as emerging producers, creating a competitive landscape where nations are weighing immediate economic relief against long-term environmental stability. A Green Pledge at Odds with Survival? The environmental implications are significant. Theresa Rodriguez-Moodie of the Jamaica Environment Trust argues that pursuing oil exploration contradicts the island's moral standing to demand climate assistance. "If we want to have any kind of moral high ground... we cannot be considering expanding the fossil fuel industry," she stated. As Jamaica navigates this complex path, it faces the challenge of reconciling its Paris Agreement commitments with the immediate economic survival of its population.

Deadly Airstrike in Northern Gaza City Claims Ten LivesAn Israeli air raid on a residential building in northern Gaza City on Wednesday night killed at least 10 people, among them four children, and left more than 20 injured. The attack unfolded despite a nominal cease‑fire that has been in place since October.Casualty and Injury Toll from the StrikeDeaths: 10 (including 4 children)Injured: 20+Location: Residential building, northern Gaza CityAl Jazeera reporter Hind Khoudary noted that children were playing nearby when the strike hit, and parents hesitated to leave their homes or tents for fear of further attacks.Ceasefire Breaches and Humanitarian Aid ShortfallTotal cease‑fire violations reported by Gaza’s Government Media Office: 3,005 over 227 daysAid trucks allowed into Gaza: 49,973 out of the agreed 135,600 (≈36% compliance)The figures underscore a widening gap between the cease‑fire terms and on‑the‑ground realities, with Israel accused of repeatedly breaching the agreement.Broader Implications for Gaza’s Humanitarian CrisisThe latest strike follows the funeral of Mohammad Odeh, head of Hamas’s armed wing, whose death a day earlier intensified tensions. Prime Minister Benjamin Netanyahu described Odeh as Hamas’s head of intelligence during the Oct. 7 attacks and highlighted Israel’s ongoing campaign against senior Hamas leaders.Relatives of Odeh, including Abu al‑Abd Odeh, warned that “the war has not stopped,” reflecting the dire conditions reported by residents.Potential Trajectory of the ConflictWith both sides accusing each other of violating the cease‑fire, the risk of a return to full‑scale war is growing. Continued restrictions on aid and the high number of violations suggest that humanitarian conditions will deteriorate unless a substantive de‑escalation occurs.

The UK-EU Reset Deal The UK and EU have announced an agreement to scrap Brexit red tape affecting UK food exports to the EU, including fresh sausages and burgers, from mid-2027. This move is part of the first confirmed result of Keir Starmer's 'reset' negotiations with Brussels. Simplifying Export Rules When the new rules come into force, exporters of meat – whether fresh, frozen or processed – will no longer require costly veterinary certificates to prove they meet EU standards. Similar documentation for plants or wood packaging material will also no longer be needed. Businesses selling into Northern Ireland will no longer require health labels. Economic Impact The deal is expected to add up to £5.1bn a year to the UK economy. The agreement will support British jobs and slash red tape for British farmers, producers, and businesses. Industry Reaction Biosecurity minister Helene Hayman said the deal was 'great news for British food and drink businesses of all sizes', including the estimated 16,000 companies that stopped exporting to the EU after Brexit due to excessive bureaucracy. Future Outlook The government is working towards a mid-2027 start date for the new agreement and wants businesses in the agri-food sector to start getting ready now. Negotiations over the deal are expected to conclude in time for the next EU-UK summit on July 13.

The US Strikes Near Bandar Abbas The United States has carried out new strikes near Iran's Bandar Abbas port, targeting what it described as military threats to its forces and maritime traffic in the Strait of Hormuz, according to reports. Iranian media said the explosions caused no casualties or property damage. Escalating Tensions in the Strait of Hormuz The latest developments come amid rising tensions around the Strait of Hormuz, a key global shipping route that has become a major flashpoint in negotiations and confrontations involving Iran and the US. Iran's Response to the Strikes Iranian state media reported explosions near Bandar Abbas port and the Strait of Hormuz for the second time since Tuesday, amid rising tensions in one of the key flashpoints in Iran-US negotiations. Iran's Tasnim news agency, quoting a military source, said the IRGC Navy fired on a US tanker, accused of crossing the Strait of Hormuz with its radar turned off. Diplomatic Efforts and Sanctions US President Donald Trump said Iran would receive no sanctions relief under any agreement and insisted Tehran would surrender its enriched uranium stockpile, despite Iran repeatedly rejecting those demands. The US Treasury Department added Iran's Persian Gulf Strait Authority to its sanctions list, targeting the body Tehran created to manage ship transit requests through the Strait of Hormuz. Regional Reactions and Developments Kuwait's military said its air defences intercepted 'hostile' missiles and drones as warning sirens sounded across the country. The Israeli military ordered residents of parts of Tyre city and Zaqqoq al-Mufdi in southern Lebanon to vacate the area immediately and move north of the Zahrani River.

The prosecution: MelanieI want to live a healthier life too, but removing all plastics is unrealistic and unaffordableMy girlfriend, Amy, has become increasingly concerned about microplastics and environmental toxins, and it is starting to feel a little too much. It all began after she watched online content about how plastics affect fertility, and has escalated into a broader effort to remove anything she considers “toxic” from our home.We have thrown out hundreds of pounds’ worth of cleaning products and replaced toothbrushes and dental floss. I came home from work to find all our plastic food containers had been binned, and now she wants to discuss replacing furniture, like swapping our white plastic dining table for an oak one.In principle, I understand it will be better for us. I share her desire to live a healthier lifestyle, especially as we are trying for a baby using a donor and I will be the one carrying the pregnancy. However, the pace and the intensity of the change feels a bit unmanageable.If I pick up a plastic bottle of water, Amy will snatch it from my hands and say it’s poisonousWe can’t realistically eliminate all plastics and find alternatives overnight. Unfortunately, the world is full of plastic and so is our home: we have polyester cushions, plastic shoes and appliances that I’m not prepared to chuck out. Attempting a total removal feels financially and emotionally unsustainable. Buying a new dining table won’t be easy on our wallets.We are both self‑employed and saving for a baby, so we need to be frugal. Plastic‑free products are often deemed as specialist and it’s hard to get cheap alternatives. When I found Amy had splurged on all these organic cleaning products I was shocked, because they cost about £200.At the moment, it feels as if any “normal” behaviour is deemed to be unsafe by her. If I pick up a plastic bottle of water, Amy will snatch it from my hands and say it’s poisonous.I support her decision to live with fewer toxins, but her level of vigilance is harming our wellbeing. I want us to make healthier choices, but to do so gradually and realistically, rather than through sweeping changes that leave us feeling anxious and restricted.The defence: AmyI’m conscious of what we’re exposed to as we’re trying for a baby and I want the best for themPlastics and chemicals are everywhere. I’m not pretending we can eliminate them all, but I’d like to make some changes. I don’t think the only rational response when presented with all the information about toxins and plastics is to shrug and accept it without question.It’s not that hard to make some changes. Mel says: “Microplastics are everywhere, so where does it end?” But she should be saying: “What can we do to start?”Small changes help improve our health. I watched a documentary and it really scared me: I learned that just brushing my teeth with my normal toothbrush was releasing hundreds of thousands of microplastics into my mouth every day. These are linked to illness and altered brain functionality.Mel hasn’t heard all of the facts. If she watched the same documentary, she would feel the sameI didn’t start looking into endocrine disruptors and microplastics because I wanted to overhaul our home overnight. It was because we’re trying for a baby and that makes me more conscious of what we’re exposed to. If we have a child, I want them to have the best start in life and be as healthy as possible.Sometimes Mel acts as if I’m trying to dismantle our entire life, but I’m just trying to make things better. Switching cleaning products and replacing plastic food storage with glass will benefit us for years. When I threw our cleaning products away, it was because I had done the research and knew how much better nontoxic ones would be for us. That wasn’t a gradual adjustment, but I don’t regret it.I feel overwhelmed sometimes, but being told to “calm down” or “take it slow” doesn’t help. I don’t want to make our lives miserable. I want us to make informed choices together.Not drinking from plastic bottles is an easy change we can make, as is using better cleaning products. Mel and I need to work together on this, and active participation is important to me. If my decisions seem rash, it’s only because Mel hasn’t heard all of the facts. If she watched the same documentary she would feel the same. I don’t want to scare her, but making our home safer for our unborn child is a priority.The jury of Guardian readersGetting rid of plastic won’t make Amy and Melanie’s home healthier if they replace it with pressure and resentment. Amy’s pursuit is noble, but her cold‑turkey approach risks alienating Melanie from the cause.Estelle, 27They both want to live with fewer toxins, but Amy shouldn’t decide the pace at which they do this without agreement from Melanie. Amy throwing out all plastic containers and cleaning products without any discussion contradicts her claim that she wants “to make informed choices together”.Val, 68Life’s too short to make it hard for yourself. Carrying containers everywhere and only going to specialist retailers? No one’s got time for that when there’s work and chores to be done. Changing your life after one documentary is extreme, and Amy should consider the benefits of plastic.Ivan, 29We can’t live perfect lives, but that doesn’t mean we shouldn’t try to make better choices. I think they plan together what can change now and what can wait, Melanie might feel part of it instead of feeling it is something being done to her.Michael, 39Amy is valiant in trying to live a healthier lifestyle, but not making it a joint decision with Melanie seems to be detrimental to their relationship, and they need to be working together when they have a child. I wonder if Amy’s obsession might be masking a deeper issue.Jon, 50Now you be the judgeIn our online poll, tell us: should Amy bin her hatred of plastics?The poll closes on Wednesday 3 June at 9am BSTLast week’s resultsWe asked, should Martin stop telling his wife how to mop the floor?98% of you said yes – Martin is guilty2% of you said no – Martin is innocent

The Lead: Labour's Internal Debate Over InequalitySenior Labour figures Wes Streeting and Andy Burnham have launched a sharp critique of former Prime Minister Tony Blair, accusing him of failing to confront inequality in his recent assessment of the party. The exchange comes as Blair published a lengthy critique of Labour's time in office under Keir Starmer, advocating for policies including cracking down on welfare spending and abandoning restrictions on oil and gas production.The Event Details: Blair's Critique and Labour's ResponseIn his essay, Blair criticized the policy proposals of both Burnham and Streeting – both widely expected to challenge Starmer for the leadership should Burnham win the Makerfield byelection. Streeting responded in a Guardian article, stating that "inequality – the economic, social and democratic fracture running through modern Britain – is treated as peripheral rather than fundamental" in Blair's analysis.Burnham, the mayor of Greater Manchester, added that "He doesn't mention inequality once" in Blair's essay, suggesting that failing to address this issue demonstrates a misunderstanding of current political dynamics. "If you don't get how that's driving politics now, if you are not rooting your analysis in the fact that people are unable to live and that things that were taken for granted are no longer affordable, then you are not understanding what's going on," Burnham stated.The Ideological Divide: Policy Disagreements Within LabourThe disagreement highlights significant policy differences within the Labour party. Streeting defended his approach to taxation, stating it was vital to "tip the balance of taxation away from work towards wealth," directly countering Blair's suggestions. He also rejected Blair's call for accommodation with US policies, criticizing Blair's war in Iraq and stating that "Atlanticism cannot mean automatic subservience."Torsten Bell, the Department for Work and Pensions minister who was a key author of Labour's last budget, supported the criticism of Blair's analysis, stating that "the challenge for the essay is that it doesn't have a project that remotely fits the time and place we are living in." Bell also disputed Blair's assessment that VAT should have been raised instead of employers' national insurance, calling it "a recipe for much higher interest rates" and inflation.The Political Implications: Leadership Challenges and Party DirectionThe exchange comes at a critical time for the Labour party, with potential leadership challenges on the horizon. Blair's critique specifically targeted the policy proposals of both Burnham and Streeting, who are seen as potential successors to Starmer. The focus on inequality suggests a strategic positioning by these figures as they prepare for potential leadership contests.Streeting emphasized that "the task of progressive politics is not to recreate yesterday, but to ensure ordinary working people have power, protection and opportunity in the world now emerging." This approach contrasts with what appears to be Blair's nostalgia for past political strategies, particularly the 1990s approach that defined his premiership.The Future Outlook: Labour's Path ForwardBlair has stated that his essay aims to "start a debate in the party about serious policy," suggesting that he views the current direction as potentially leading to "real trouble" for the country. However, the response from senior Labour figures indicates that any debate will necessarily center on the role of inequality in British politics and the appropriate response to economic challenges.The exchange also highlights the ongoing tension within Labour between different generations of leadership and their approaches to policy. As the party considers its future direction, the debate over inequality appears set to remain central, with Streeting and Burnham positioning themselves as champions of addressing economic disparities that they see as fundamental to modern British politics.

The Escalation in Southern LebanonIsrael has significantly increased its military activities in Lebanon, particularly in the southern regions, despite ongoing ceasefire agreements with Hezbollah. This escalation marks a notable shift in the security dynamics of the border area, with Israeli forces conducting more frequent airstrikes and artillery shelling in recent weeks.Strategic Objectives Behind the OffensiveAccording to military analysts, Israel's intensified campaign appears aimed at degrading Hezbollah's capabilities and infrastructure. The Israeli government has stated that these operations are necessary to prevent what it describes as "imminent threats" from the Lebanese militant group, which has been rebuilding its arsenal since the last major conflict in 2024.International Response and Diplomatic FalloutThe escalation has drawn condemnation from several international bodies, with the United Nations expressing concern over the potential for wider regional conflict. Diplomatic efforts to restore calm have intensified, though both sides appear entrenched in their positions. The United States has called for restraint while maintaining its support for Israel's right to defend itself.Humanitarian Impact on Lebanese CiviliansThe increased hostilities have had severe consequences for civilian populations in southern Lebanon. Reports indicate dozens of civilian casualties and the displacement of thousands as residential areas come under fire. Humanitarian organizations warn of a developing crisis as access to basic necessities becomes increasingly difficult in affected regions.Regional Implications and Future OutlookThis escalation risks destabilizing an already fragile region, potentially drawing in other actors and reigniting broader conflicts. Military experts suggest that unless diplomatic intervention succeeds in de-escalating tensions, the situation could deteriorate further, potentially leading to another full-scale conflict between Israel and Hezbollah with unpredictable regional consequences.
