Why JansBrief exists
Jan Stenbeck was the smartest person I ever met. Not smart in the way academics are smart. Smart in the way that changes the world. He saw what nobody else saw. He understood that mobile telephony would revolutionise countries that hadn't even laid copper wire yet. He broke state socialist monopolies when everyone said it was impossible. He built empires out of ideas.
Every day Jan received a binder. Two people read all the world's important newspapers and magazines for him and pulled out what mattered. The things others missed. The faint signals that foreshadow great change.
I worked with Jan. I learned from him. And I have never forgotten that binder. JansBrief is my tribute to him, a modern version: global, AI-driven, available to everyone with ambition.

A ten-storey apartment block in north London is now standing — and it is held up not by steel or reinforced concrete but by an exoskeleton of unreinforced volcanic rock. Petra Heights, designed by architecture studio Groupwork and structural engineers Webb Yates, uses a thousand tons of stone arranged in a ladder-like frame around three residential blocks on Finchley Road. The studio calls it a world first for high-rise construction.
The principle is ancient. Stone has been bearing loads since the Egyptians. But twentieth-century building codes, insurance frameworks, and engineering curricula systematically pushed it out of anything taller than a few storeys. Concrete and steel became not just dominant but assumed — so deeply woven into regulation, supply chains, and professional identity that proposing a stone high-rise felt less like innovation than provocation.
What changed is a convergence of three pressures. First, embodied carbon. Concrete production alone accounts for roughly eight per cent of global CO₂ emissions; steel adds another seven. Stone, quarried and cut, carries a fraction of that footprint. Second, computational structural analysis now lets engineers model complex load paths through irregular natural materials with a confidence that was impossible a generation ago — parametric software can optimise a stone grid the way it optimises a steel truss. Third, and most quietly, the economics of conventional materials have shifted. Steel prices remain volatile, cement faces carbon levies in the EU and UK, and labour shortages in concrete trades have driven construction costs upward. A material that can be cut by CNC machines and assembled with smaller crews starts to look not just virtuous but competitive.
Petra Heights is not a pavilion or a folly. It is housing — six to ten storeys, designed for people to live in, financed and insured through normal channels. That is what makes it a signal rather than a stunt. The project had to clear UK building regulations, which were written for steel and concrete. Webb Yates developed bespoke testing regimes and modelling protocols to satisfy structural safety requirements. The fact that they succeeded means a regulatory pathway now exists for others to follow.
The implications run well beyond one London postcode. If stone exoskeletons can meet high-rise safety standards in the UK — one of the world's most stringent regulatory environments — then the method becomes replicable wherever good building stone is available, which is a remarkably large part of the planet. Countries across the Middle East, East Africa, and South Asia sit on vast limestone and basalt reserves. For them, this is not an imported technology but a rediscovery of a local one, upgraded with modern engineering.
None of this means concrete and steel are going away. But the assumption that they are the only serious structural option for tall buildings has, as of Finchley Road, been physically disproved. That is how materials revolutions begin — not with a manifesto, but with a building that stands up.

Now: Petra Heights creates a live, inhabitable precedent. Developers, insurers, and regulators in the UK now have a completed project to point to. Expect the first planning applications citing it as proof-of-concept within months. The embodied-carbon argument alone will attract ESG-motivated capital.
Soon: Building codes across Europe are already under revision to accommodate low-carbon materials. The EU's forthcoming revision of the Construction Products Regulation is expected to introduce lifecycle carbon metrics. A proven stone high-rise shifts the debate from theoretical to operational: regulators can no longer argue that alternatives to steel and concrete are unproven at scale. Quarrying regions — from Lecce in southern Italy to Rajasthan in India — could see new demand for precision-cut structural stone, creating industrial opportunities in places that globalisation has largely bypassed.
Later: The deeper disruption is conceptual. For a century, "modern" construction has meant industrial materials manufactured in centralised plants. Stone exoskeletons, combined with CNC cutting and parametric design, suggest a model where the structural material is local, the intelligence is in the software, and the carbon is radically lower. If this model matures, it could reshape construction economics in the Global South, where cement imports are a major dollar drain and local stone is abundant. The tallest buildings of the mid-twenty-first century may not be monuments to steel but to the oldest material on earth, made new by computation. Source: Dezeen · 7 September 2026 ---
A coalition of Nigerian opposition parties has taken concrete steps toward a joint front ahead of the 2027 presidential election. Public-interest lawyers and party strategists are building a framework for a common candidate, an effort that has historically collapsed under ego and ethnic arithmetic. What makes this round different is the shared recognition that the ruling APC's grip depends on a fractured opposition. Whether the alliance survives candidate selection remains the central question, but the machinery is moving earlier than in any previous cycle. Source: Business Day Nigeria · 8 September 2026
Staff at the Eiffel Tower walked off the job on Monday after women were reportedly asked to step aside during a visit by a Hindu religious group. The operator, SETE, closed the monument for the day. The incident touches a raw nerve in France, where laïcité — the strict separation of religion and public life — remains a constitutional principle and a persistent flashpoint. Union representatives said the request violated workplace dignity standards. Source: Al Jazeera · 8 September 2026
Huawei is playing a quiet but central role in coordinating China's effort to manufacture the advanced lithography equipment it can no longer buy from the Netherlands. The Financial Times reports that the telecoms-and-technology giant has taken on a "project management" function, orchestrating the dozens of domestic suppliers needed to assemble deep-ultraviolet (DUV) machines capable of producing advanced chips without ASML's tools. The effort is a direct response to tightening US, Dutch, and Japanese export controls. Success is not guaranteed — lithography is among the most technically demanding manufacturing processes ever devised — but the scale of state-backed investment and Huawei's track record of working around sanctions mean the attempt cannot be dismissed. If China achieves even partial self-sufficiency in chipmaking equipment, the strategic calculus of semiconductor export controls changes fundamentally. Source: Financial Times · 8 September 2026
Yemeni government forces have opened a new offensive against Houthi positions, with fighting concentrated in the provinces of al-Bayda and al-Jawf. Officials have declared the intention to retake the capital, Sanaa, held by the Houthis since 2014. The timing is not accidental: the Houthis simultaneously claimed strikes on Saudi Arabia's Abha Airport, King Khalid air base, and Aramco facilities, escalating a multi-front conflict that now stretches from the Red Sea shipping lanes to the Arabian interior.

A new analysis argues that Cambodia's much-touted modernisation drive is hitting a structural wall. The necessary reforms — land tenure transparency, judicial independence, competitive procurement — directly threaten the patronage networks that keep the ruling party in power. The result is a developmental stalemate dressed in the language of reform: new roads and digital ID systems coexist with an unreformed political economy that blocks the productivity gains those investments are meant to unlock.

Uruguayan ferry company Colonia Express has government authorisation to run a Montevideo–Buenos Aires passenger route but cannot begin service because the only vehicle-unloading ramp at Montevideo port belongs to incumbent operator Buquebus. The dispute is a textbook case of infrastructure monopoly: the licence exists, the demand exists, but physical access is controlled by the competitor. Uruguay's transport ministry has yet to intervene. Source: Mercopress · 8 September 2026
Ethiopian Airlines is capturing a growing share of Nigerian outbound passengers by flying directly into regional hubs that Nigerian carriers cannot reach — a consequence of Nigeria's persistent infrastructure deficits in maintenance facilities, pilot training, and airport capacity. The dynamic highlights a paradox: Africa's largest economy is subsidising the aviation sector of a much smaller neighbour because it cannot get its own airports and airlines to function.

Somewhere in Montevideo, a ferry company has done everything right. Colonia Express obtained its operating licence. It secured government authorisation from Uruguay's Ministry of Transport. It has a boat, a route, a market — thousands of passengers and vehicles moving between Montevideo and Buenos Aires every week. And it cannot sail.
The reason is grimly simple. The only ramp at Montevideo's port capable of unloading vehicles belongs to Buquebus, the incumbent operator that has run the crossing for years without serious competition. Buquebus controls the physical chokepoint. No ramp, no cars. No cars, no viable business.
This is a monopoly story stripped to its skeleton. It is not about technology or regulation or consumer preference. It is about a single piece of concrete infrastructure — a ramp — that one company owns and another needs. The government granted the licence but did not ensure access to the facility that makes the licence usable. The paperwork is pristine. The competition is impossible.
What makes this worth watching is what happens next. Colonia Express can litigate, lobby, or build. It could pressure the port authority to construct a second ramp. It could find an alternative berth. It could make the case — publicly, loudly — that a state-sanctioned monopoly over port infrastructure is incompatible with the competition the state itself authorised. The playbook for breaking comfortable monopolies is well-known: find the technical workaround, expose the absurdity, and make the incumbents' defence of their position look like what it is.
Uruguay is a small, well-governed country that prides itself on institutional transparency. That makes this fight more interesting, not less. The monopoly is not hidden behind corruption or state ideology. It is sitting in plain sight, bolted to a dock. The question is whether anyone with enough stubbornness and ingenuity will find a way around it — or through it.

The highway that Steinbeck called "the mother road" was commissioned on 11 November 1926 and is now entering its centennial year. Artnet traces how the route reshaped American visual culture — from Dorothea Lange's Depression-era photographs to Ed Ruscha's deadpan gas station series to Bob Dylan's paintings of roadside America. The centennial is prompting new exhibitions and commissions along the route's 2,400-mile path from Chicago to Santa Monica, but the deeper story is about how a road built for commerce became a canvas for national mythology.

In *The Debut*, premiering at fall festivals, Eisenberg directs Moore as a suburban housewife who loses herself in community theatre. Eisenberg describes her performance as "so good and so weird" — a study in how amateur performance can crack open a life that respectability has sealed shut. The film is Eisenberg's second as director, after *When You Finish Saving the World*, and continues his interest in characters whose self-image collapses under gentle pressure.

Over two decades of drought, wildfire, and salmon collapse, Oregon has thrown small fixes at its landscape — fish ladders here, forest thinning there. Now the state is turning to an older engineer. Beaver reintroduction programmes are demonstrating measurable results: their dams slow water flow, raise water tables, create wetland habitat, and reduce wildfire fuel loads. The approach is cheap, self-sustaining, and increasingly backed by hydrological data. The beaver, it turns out, is infrastructure. Source: Reasons to be Cheerful · 8 September 2026
The Icelandic singer Laufey performed Luiz Bonfá's "Perdido de Amor" in Portuguese on the Sunset stage at Rock in Rio, a gesture that landed with a Brazilian audience primed to be sceptical of foreign artists attempting their national music. That a 25-year-old from Reykjavík is singing mid-century Brazilian jazz to tens of thousands — and being embraced for it — says something about how musical taste now moves along affinity lines rather than national ones.

A century ago, the Pan-American road promised to bind the Americas into a single corridor of fraternity and commerce. Aeon's Shawn Miller traces what actually happened: the highway exists in fragments, interrupted by the Darién Gap, by political indifference, and by the practical reality that continental solidarity is easier to announce than to pave. The essay is a quiet demolition of grand infrastructure promises — relevant wherever leaders announce transformative corridors without budgets. Source: Aeon · 8 September 2026
Nathan Fielder and Lance Oppenheim stunned the Telluride Film Festival with *You Can See Everything*, a documentary about Elizabeth Holmes made with unprecedented access to the Theranos founder. The film reportedly avoids the prosecutorial tone of prior Holmes coverage, instead examining the psychology of belief — Holmes's belief in herself, investors' belief in her, and the audience's belief that they would never have been fooled. Early reviews call it disorienting and uncomfortably generous. Source: TechCrunch · 8 September 2026 ---
Eric Wu, who built Opendoor into a multi-billion-dollar company before stepping away in 2022, has brought his new venture NavigateAI out of stealth with $25 million in backing from Elad Gil, Khosla Ventures, and homebuilder Lennar. The company builds AI copilots that give construction workers real-time, hands-free guidance through smartphones and Meta's AI glasses. The target problem is blunt: the US construction industry is short hundreds of thousands of skilled workers, and the data-centre boom alone requires four to five thousand labourers per project. NavigateAI's bet is that overlaying step-by-step visual instructions onto a worker's field of view can compress training timelines and reduce costly errors — turning a novice into a competent installer faster than any classroom could. If it works at scale, the implications reach beyond labour shortages: every step captured by the system becomes a data layer that can be analysed for safety, quality, and efficiency. Construction, one of the last major industries to resist digitisation, may finally be forced into it — not by management consultants, but by the simple arithmetic of not having enough people to hold the tools.

MIT Technology Review highlights a global flurry of exploration for naturally occurring geological hydrogen — so-called "white hydrogen" or "gold hydrogen" — trapped in underground rock formations. Unlike green hydrogen (made by splitting water with renewable electricity) or grey hydrogen (made from natural gas), geological hydrogen requires no energy input to produce. If commercially viable deposits exist at scale, they could undercut the economics of every other hydrogen pathway. Exploration is now underway in Mali, where a well has been producing hydrogen since 2012, as well as in Australia, the US, and France. The science is early and the geology uncertain, but the potential payoff — a zero-carbon fuel that comes out of the ground ready to use — is large enough to justify the search.

New Scientist reports that physicists are on the verge of directly observing the quantum vacuum — the seething, not-quite-empty state that quantum theory predicts beneath apparent emptiness. A new experiment using extraordinarily powerful lasers aims to detect the fleeting particle pairs that pop in and out of existence in "empty" space. If successful, it would be the first direct evidence of vacuum structure, a result with implications for dark matter physics and potentially for the foundations of quantum field theory itself. The experiment is a reminder that the most consequential science often happens at the boundary of what can be measured. Source: New Scientist · 8 September 2026 ---

That is where Brent crude is now trading — holding near one hundred dollars a barrel as traders watch two forces collide. On one side, strong Chinese buying has tightened physical supply. On the other, Iran and Oman are negotiating an arrangement to manage shipping through the Strait of Hormuz, the chokepoint through which roughly a fifth of the world's oil passes daily. The price is not a spike; it is a plateau, sustained by a market that has absorbed months of Middle Eastern instability, OPEC discipline, and resurgent Asian demand without finding enough new supply to bring the cost down. For importing nations — from India to Kenya to the Philippines — triple-digit oil is a direct tax on growth. For US voters heading toward November's congressional elections, it lands as the price on the pump sign they see every morning. One hundred dollars is the number at which energy policy stops being abstract and starts deciding elections.

8 — Today's Wisdom
A ten-story building in north London is now held up by volcanic stone. No rebar, no concrete in the structural frame, just stone cut with CNC machines and optimized with parametric software. It's not an art project. It's housing, financed and insured through ordinary channels, approved under British building codes that were written for steel and concrete.
What strikes me isn't that it works. Stone has carried loads for five thousand years. What strikes me is how long it took to circle back to the obvious. Concrete accounts for eight percent of global CO₂ emissions, steel for another seven. Stone, quarried and cut, has a fraction of that footprint. Yet for an entire century, an entire industry treated these industrial materials as the only serious options—not because they were superior in every application but because regulations, training programs, and insurance models were built around them until no one questioned the assumption anymore.
This is a pattern I recognize from tech. The most profitable breakthroughs are rarely about inventing something new. They're about seeing that the thing everyone takes for granted, the practice no one questions, actually rests on an assumption that expired long ago. And then having the courage to build as if the assumption doesn't exist.
Petra Heights is not a revolution. It's proof that the revolution was already possible. Someone just had to stand up and start laying stone.
