Sorry to spoil your party, @EU_Commission.
15 of 27 member states break the Maastricht rules. Not one of the big four meets both criteria. Germany, France, Italy and Spain all fail. Meanwhile the Netherlands plays by the book and gets asked to pay for joint debt.
You should enforce, to ensure stability.

Het pijnlijke zelfonderzoek van de republikeinen
De uitslag van aanstaande dinsdag weten we nog niet, maar zelfs als de republikeinen op het nippertje de meerderheid in het congres uit handen van de democraten weten te houden, volgt er een pijnlijke periode van politiek zelfonderzoek. De partij heeft de afgelopen jaren, eigenlijk sinds de eerste kandidatuur van Donald Trump in 2016, elke vorm van kritisch politiek denken taboe verklaard. Dat is geen probleem zolang je wint. Als de voortekenen niet bedriegen wordt die politieke luwte aanstaande dinsdag door een ware electorale orkaan verstoord.
Het was oud-adviseur Steve Bannon die in een interview met de Financial Times zelfs waarschuwde voor een politieke burgeroorlog binnen de republikeinse partij. Met aan de ene kant de trouwe Trump-aanhang die weigert de lessen van 10 jaar arrogant Trumpisme ter harte te nemen. En aan de andere kant de republieken die de afgelopen jaren onder een politieke steen hebben gezeten, maar nu hun kans schoon zullen zien om de partij weer in traditioneel conservatief vaarwater te brengen. Het kan een bloedige politieke afrekening worden.
Sterke man Donald Trump heeft de partij zwak gemaakt. Geen discussie, geen nieuwe vrienden, geen toekomstperspectief, geen oplossingen voor de grote problemen van het land.
Congresleden dachten dat ze die inhoudelijke zwakte konden verstoppen onder het lefgozergedrag van Donald Trump. De vanzelfsprekendheid van “ze stemmen toch wel op The Donald’ is uitgewerkt.
De sterke man kan alleen maar pieken. Hoger, steeds hoger tot het misgaat en dan gaat het ook snel.
Dat moment kan dinsdag aanbreken. Dan komt er die heftige discussie en het belabberde perspectief van de politieke ratten die het zinkende schip verlaten.
Een fantastische kans voor de democraten. Maar ze zijn er ook goed in dat soort kansen te verkwanselen.
Hun zwakte werd pijnlijk duidelijk door het theatrale optreden optreden afgelopen week van Barack Obama. Er was weer het pijnlijke besef: ‘zo eentje hebben we er nu niet’. Obama is, zoals Bill Clinton dat in z’n goede dagen was, een natuurtalent. Het gemak en de humor waarmee hij een zaal van vele duizenden aanhangers toespreekt was voor de democraten hartverwarmend, maar dus ook ontnuchterend. Obama zou, als hij nog een keer mee mocht doen, in 2028 elke denkbare Republikeinse kandidaat knock-out verslaan.
Maar goed, eerst aanstaande dinsdag en de politieke guerilla die waarschijnlijk in de Republikeinse partij zal losbarsten.
Het leven is niet saai.

You'll always be a legend for this
I have just informed my colleagues that I will step down as @ECB President on 7 February 2027.
It has been a source of great pride to serve this institution.
I thank all of those who have supported me on this journey over the past seven years.

Bitcoin Core is some of the most reviewed code in the world.
We were curious how our frontier AI model would handle it. Last month we ran 16 agents across 5 of the top models for a week to look for issues in Bitcoin Core v32.0rc1
Impressively, they surfaced two minor items - both now disclosed responsibly.
Agentic teams have been a huge unlock so far for our security efficiency. They're also remarkable to watch.

I would hope, although I seriously doubt it, that this began with a mea culpa about his own inaction when Putin invaded Ukraine in 2014. Yes, we want everyone supporting Ukraine against Russia aggression, but Obama is a badly flawed messenger.

This is honestly shocking.
Three months ago, Hong Wang was awarded the Fields Medal for resolving the Kakeya conjecture in three dimensions.
Today, OpenAI released a proposed proof of the conjecture in ALL dimensions.
And that’s not all. It also announced a proposed existence proof for quantum chromodynamics and a proposed refutation of the Exponential Time Hypothesis.
Experts say that, if confirmed, these would be Nobel prize and Turing award level discoveries respectively.
A journalist just asked me: “What remains for humans to do?”
I think it’s becoming increasingly clear that more and more problem solving will be automated.
But humans will remain crucial in determining the direction of discovery. Deciding which problems are worth solving.
Because the value of a discovery depends on our needs, our priorities and the kind of world we want to build.
There will be a shift from problem solving to problem setting.
I also think there will be huge individual differences.
People with strong critical thinking skills, creativity and imagination will be supercharged by AI.
People without those skills risk surrendering to it.
I’m particularly concerned for children, who may never develop these skills.
I think epistemic literacy - how to distinguish information from knowledge - is the single most important skill we should be teaching.

Vorige week heeft OpenAI 700 wiskundige papers gepubliceerd. Mijn aanstaande schoonzoon zit in de wereldtop in quantumfysica. Hij vertelde dat er wiskundigen in tranen waren. Mensen die hun hele carriere besteed hadden aan iets uit te zoeken, waren met een paar uur AI-rekenen ingehaald. Het hele veld verandert.

China's 2008 is happening now.
Property investment in China dropped -21% YoY in the first 9 months of 2026, its largest decline for this period of the year on record.
This marks a deterioration from a -20% YoY decline in the first 8 months of 2026.
The latest drop is also significantly worse than the -16% decline recorded during the 2020 pandemic.
Property investment in China has now contracted every month since 2022, its longest declining streak on record.
For perspective, during the 2008 Financial Crisis, this figure never fell below +1% YoY growth.
China's property sector is experiencing a historic downturn.

**You need to watch Zelenskyy's interview with Steven Bartlett.**
Sitting in front of the camera is an utterly exhausted, at times visibly broken man who has spent almost five years personally managing a war, making critical decisions day and night.
From the very first minutes, you can see just how drained he is. When asked the routine question, "How are you?" he replies that he barely sleeps because he spends his nights in military group chats, moving the last remaining air defense systems from one region to another.
Two stories are particularly heartbreaking.
The first is about a missile that struck a children's playground within seconds, while parents watched from their apartment windows as their children were torn apart.
The second is about presenting posthumous military awards to the families of fallen soldiers:
"You present an award to a father, feel his strong hand, and then he quietly asks, 'Can we hug?' At that moment, I simply cease to exist inside. These people are gone. They will never be the same again."
When the host tries to take him back into his past, showing old photographs from Kryvyi Rih, his student comedy performances, his voice acting as Paddington Bear, and scenes from *Servant of the People*, Zelenskyy looks at them with detachment, almost as though he is watching someone else's life.
He also recalls February 2022 without any attempt to portray himself as a hero.
He says that for the first 20 days, he simply ran from office to office on adrenaline, calling everyone he could and trying to organize deliveries of water and food to Kyiv.
Fear and the full realization of what had happened only caught up with him three weeks later, when Bucha was liberated and mass graves containing hundreds of murdered civilians were discovered.
Using Bucha as an example, he explains why advice from outsiders to simply negotiate a quick deal causes him such deep frustration:
"Imagine that in the United States or Britain, a mass grave is discovered containing 500 tortured people with their hands tied. How could you simply forgive everything after that?"
The rest of the conversation revolves around the deadlock in which Ukrainians, and indeed everyone involved, now find themselves.
Zelenskyy explains the causes of the war in simple terms: Moscow is trying to forcibly rebuild the Soviet empire because Ukraine's integration into Europe would finally bury that project.
But when the conversation turns to the present, there is unmistakable bitterness in his words.
Almost one-fifth of Ukraine's territory is occupied. The east is under relentless bombardment. Cities are left without electricity. People are dying every single day.
Meanwhile, every discussion about a ceasefire runs into the same demand: Kyiv must withdraw even farther from its fortified positions, without any guarantees that Russia will not launch another offensive a year later.
Toward the end, the conversation turns to Trump and Ukrainian strikes on Russian oil facilities.
Trump publicly reprimands Zelenskyy over attacks on Russian refineries because he fears rising diesel prices for American farmers ahead of the elections.
And this is where you can see just how deeply that approach affects Zelenskyy.
His country is burning.
Moscow has rejected his proposal for a mutual halt to attacks on energy infrastructure.
Patriot missiles paid for by Europe are being redirected by the Americans to the Middle East.
And somehow, Zelenskyy is the one being blamed for fuel prices in the United States.
The entire interview leaves you with a profoundly bleak feeling.
Here is a man trapped between the daily deaths of people in his own country and the pragmatic bargaining of allies who have their own elections, their own interests, and their own political calculations.
And yet, he can no longer step away from this responsibility.
**Watch it.**

Nederland kan niet langer in dezelfde muntunie met Frankrijk.
🇳🇱 Nederland: schuld 45%, tekort 1,6%.
🇫🇷 Frankrijk: schuld 116%, tekort 5,1%.
Maastricht zegt 60% en 3%. Slechts 12 van de 27 EU-landen halen dat.
De regels gelden alleen nog voor wie ze toch al naleefde (wij onder andere)

De rente van Frankrijk op de obligatiemarkten is zojuist door de 5% gegaan, onhoudbaar! De ECB zal wel ingrijpen maar dat zorgt voor nog meer inflatie in Nederland. Als je samen in een euro zit, betaal je belasting voor het mismanagement van anderen.

Absolutely incredible.
For the first time since 2013, France's 10Y Government Bond yield has risen above the US 10Y Note Yield.
That's +550 basis points since the low seen in 2020.
Borrowing costs are skyrocketing in France.

As i said human and AI can work together on these things.
Mathematicians Validate an AI-Generated Proof of Brennan's Conjecture.
Four mathematicians, including 2010 Fields Medalist Stanislav Smirnov, have examined OpenAI's proposed solution to Brennan's conjecture, a longstanding problem in complex analysis dating to 1978.
In a manuscript submitted on 16 October 2026 and listed by arXiv on 19 October, Ilia Binder, Oleg Ivrii, István Prause, and Stanislav Smirnov report that the AI-generated argument is correct but unnecessarily lengthy. They identify its essential mathematical ideas, produce a substantially shorter proof, and formulate a stronger result.
Brennan's conjecture concerns the integrability of derivatives of conformal maps. For a conformal map g: Ω → 𝔻, where Ω is a simply connected proper plane domain, it predicts
∫_Ω |g′(z)|ᵖ dA(z) < ∞, for 4/3 < p < 4.
The researchers also state a stronger bound for the bounded universal integral-means spectrum:
B_b(t) < t²/4, for −2 < t < 2, t ≠ 0.
The manuscript proves the corresponding non-strict inequality, while the details establishing strictness are deferred to a subsequent paper. The work has not yet undergone peer review.
This development illustrates an important relationship between AI-generated mathematics and human mathematical expertise. An AI-produced argument has prompted mathematicians to isolate its central ideas, simplify its reasoning, and investigate a stronger theorem.
