Spain fact of the day
Spain’s grid ran entirely on renewable energy for the first time on April 16, with wind, solar, and hydro meeting all peninsular electricity demand during a weekday. Five days later, solar set a new record, generating 20,120 MW of instantaneous power – covering 78.6% of demand and 61.5% of the grid mix.

AI Goes to College…for the Free Money
Last year, the state [CA] chancellor’s office estimated 25 percent of community college applicants were bots.
Everyone understands that students are using AI; sometimes to help them learn, sometimes to avoid learning. What I didn’t appreciate is that community colleges offering online courses are being flooded with AI bots who are taking the courses:
The bots’ goal is to bilk state and federal financial aid money by enrolling in classes, and remaining enrolled in them, long enough for aid disbursements to go out. They often accomplish this by submitting AI-generated work. And because community colleges accept all applicants, they’ve been almost exclusively impacted by the fraud.
The state has launched a Bladerunner-eque “Inauthentic Enrollment Mitigation Taskforce” to try to combat the problem. This strikes me, however, as more of a problem on the back-end of government sending out money without much verification. It’s odd to make the community colleges responsible for determining who is human. Stop sending the money to the bots and the bots will stop going to college.
Sam Altman, as usual, is ahead of the game.
Spain facts of the day
- In 1990, less than 1% of the Spanish population were foreign residents. The foreign-born population was even smaller, with immigrants accounting for about 0.5% of residents.
- In 2023, Spain alone accounted for 23% of all naturalizations in the European Union
As of 2025…
- 14% of residents in Spain are foreign nationals.
- Nearly 20% of Spain’s population was born outside the country.
- 1 in 7 residents of Madrid were born in Latin America.

The Library Burned Slowly
A powerful but grim essay by John McGinnis, Professor of Constitutional Law at Northwestern. For decades, the federal government—driven by the left—expanded its control over universities. The right, most notably Ronald Reagan, tried to resist, shielding civil society from state overreach. They failed. Now, a new right has turned to the left’s playbook and is imposing its own vision of the good society. Chris Rufo mocks classical liberals like myself and their naive ideas of neutrality, fairness and open institutions. Principles are for losers. Seize power! Crush your enemies. Rufo does know how to crush his enemies. But what happens when the devil turns? Bludgeoning your enemies is fun while it lasts but you can’t bludgeon your way to a civilization. Hayek’s civil society dies in the rubble.
It seems remarkable that seemingly antisemitic protests by undergraduates, such as those at my own university of Northwestern, could threaten the biomedical research funding of its medical school. But the structure of civil rights laws as applied to universities has long allowed the federal government to cut off funding to the entire university based on the wrongful actions of particular units or departments.
Ironically, the left, now alarmed by the federal government’s intrusive reach, bears direct responsibility for crafting the very legal weapons wielded against the universities it dominates. Almost four decades ago, progressive legislators demanded sweeping amendments to civil rights law, expanding federal oversight over higher education. The sequence of events reveals a cautionary tale of political hubris: progressive confidence that state power would reliably serve their ends overlooked the reality that governmental authority, once unleashed, recognizes no ideological master. Today’s circumstances starkly illustrate how expansive federal control over civil society, originally celebrated by progressives, returns to haunt its architects. The left’s outrage ought to focus not on this particular administration but on its own reckless empowerment of the state.
…Clumsy governmental dictates on contentious matters such as transgender rights do not merely settle disputes; they inflame societal divisions by transforming moral disagreements into winner-takes-all political battles. Civil society, by contrast, thrives precisely because it embraces diversity and facilitates compromise, allowing pluralistic communities to coexist peacefully without being conscripted into ideological warfare. The left, fixated upon uniform outcomes, consistently undervalues the power of voluntary cooperation and cultural persuasion. Their shortsightedness has delivered into the hands of their opponents the very instruments of coercion they forged, vividly confirming an enduring truth: the power you grant government today will inevitably be wielded tomorrow by your adversaries.

My excellent Conversation with Chris Dixon
Here is the audio, video, and transcript. Here is the episode summary:
Chris Dixon believes we’re at a pivotal inflection point in the internet’s evolution. As a general partner at Andreessen Horowitz and author of Read Write Own, Chris believes the current internet, dominated by large platforms like YouTube and Spotify, has strayed far from its decentralized roots. He argues that the next era—powered by blockchain technology—can restore autonomy to creators, lower barriers for innovation, and shift economic power back to the network’s edges.
Tyler and Chris discuss the economics of platform dominance, how blockchains merge protocol-based social benefits with corporate-style competitive advantages, the rise of stablecoins as a viable blockchain-based application, whether Bitcoin or AI-created currencies will dominate machine-to-machine payments, why Stack Overflow could be the first of many casualties in an AI-driven web, venture capital’s vulnerability to AI disruption, whether open-source AI could preserve national sovereignty, NFTs as digital property rights system for AIs, how Kant’s synthetic a priori, Kripke’s modal logic, and Heidegger’s Dasein sneak into Dixon’s term‑sheet thinking, and much more.
Most of the talk was about tech of course, but let’s cut right to the philosophy section:
COWEN: What’s your favorite book in philosophy?
DIXON: I’ve actually been getting back into philosophy lately. I did philosophy years ago in grad school. Favorite book, man. Are you into philosophy?
COWEN: Of course, yes. Plato’s Dialogues; Quine, Word and Object; Parfit, Reasons and Persons; Nozick. Those are what come to my mind right away.
DIXON: Yes. I did analytic philosophy. I actually was in a graduate school program and dropped out. I did analytic philosophy. Actually, Quine was one of my favorites — Word and Object and Two Dogmas of Empiricism, all those kinds of things. I like Donald Davidson. Nozick — I loved Anarchy, State, and Utopia. Reading that with Rawls is a great pairing. I used to love Wittgenstein, both early and later. I was into logic, so Frege and Russell. This was a grad school.
Now I’m trying to finally understand continental philosophy. I never understood it. I’ve actually spent the last three months in a philosophy phase. I’ve been watching a lot of videos. Highly recommend this. Do you know Bryan Magee?
COWEN: Sure, yes.
DIXON: Amazing. I watched all of his videos. This guy, Michael Sugrue, was a Princeton professor — great videos on continental philosophy. I’ve been reading — it sounds pretentious; I’m not saying I understand this or I’m an expert on it, but I’m struggling in reading it. I’m trying to read Being and Time right now — Heidegger. I really like Kripke. I follow Kripke. I liked his books a lot. Nelson Goodman was one of my favorites. Funny enough, I just bought it again — Fact, Fiction, and Forecast. Kripke — Naming and Necessity is his legendary book on reference and language.
COWEN: I’ve never been persuaded by that one. It always felt like sleight of hand to me. He’s very, very smart. He might be the sharpest philosopher, but I like the book on Wittgenstein better.
DIXON: He basically invented modal logic. I don’t know if you know that story. He was in high school, something.
COWEN: He was 15 years old, I heard. Yes.
DIXON: [laughs] He’s like a true prodigy. Like a lot of philosophy, you have to take it in the context, like Naming and Necessity I think of as a response — gosh, I’m forgetting the whole history of it, but as I recall, it was a response to the descriptive theory of reference, like Russell. Anyways, I think you have to take these things in a pairing.
Actually, last night I was with a group of people. I got a lecture on philosophy, and it was great because he went through Hume, Kant, Hegel, Nietzsche. I don’t want to go too much into that, but I’ve always struggled with Kant. Then he went into Hegel and explained that Hegel struggled with Kant in the same way that I did, and then improved on it. I’m not trying to go into details of this; it’s too much. The point is, for me, a lot of it has to be taken in as a dialogue between thinkers over multiple periods.
COWEN: Are you getting anything out of Heidegger? Because I sometimes say I’ve looked at every page of that book, but I’m not sure I’ve read it.
DIXON: It’s a good question. I have a friend who’s really into it, and we’ve been spending time together, and he’s trying to teach me. If you want, I’ll send you some videos that I think are really good.
COWEN: That’d be great.
DIXON: They’ve helped me a lot. I’ve always got it from an intellectual history point of view. If you want to follow the history of postmodernism, there’s Heidegger and then Derrida, and just what’s going on in the academy today with relativism and discourse and hermeneutics. I think it’s modern political implications that were really probably kicked off by Nietzsche and then Heidegger. I’ve always understood in that sense.
What I struggle with, and I understand him as a theory of psychology, I think of describing the experience of the Dasein and being-in-the-world. To me, it’s an interesting theory of psychology. You’re thrown into the world. This whole idea is very appealing to me. Just that whole story he tells — you’re thrown into the world, ready at hand versus present at hand. I think this idea of knowing how versus knowing that, different kinds of knowledge is a very interesting idea. Do you watch John Vervaeke?
COWEN: No.
You will find the (very interesting) tech segments all over the rest of the dialogue. And I am happy to refer you all to the new paperback edition of Chris’s new book Read Write Own: Building the Next Era of the Internet.
Rachel Glennerster calls for reforming foreign aid
Aid agencies already try to cover too many countries and sectors, incurring high costs to set up small programs. Aid projects are far too complicated, resembling a Christmas tree weighed down with everyone’s pet cause. With less money (and in the US, very few staff), now is the time to radically simplify. By choosing a few highly cost-effective interventions and doing them at large scale in multiple countries, we would ensure
- aid funds are spent on highly effective projects;
- we benefit from the substantial economies of scale seen in development;
- a much higher proportion of aid money goes to recipient countries, with less spent on consultants; and
- politicians and the public can more easily understand what aid is being spent on, helping build support for aid.
The entire piece is excellent.
We need more elitism
Even though the elites themselves are highly imperfect. That is the theme of my latest FP column. Excerpt:
Very often when people complain about “the elites,” they are not looking in a sufficiently elitist direction.
A prime example: It is true during the pandemic that the CDC and other parts of the government gave us the impression that the vaccines would stop or significantly halt transmission of the coronavirus. The vaccines may have limited transmission to some partial degree by decreasing viral load, but mostly this was a misrepresentation, perhaps motivated by a desire to get everyone to take the vaccines. Yet the vaccine scientists—the real elites here—were far more qualified in their research papers and they expressed a more agnostic opinion. The real elites were not far from the truth.
You might worry, as I do, that so many scientists in the United States have affiliations with the Democratic Party. As an independent, this does induce me to take many of their policy prescriptions with a grain of salt. They might be too influenced by NPR and The New York Times, and more likely to favor government action than more decentralized or market-based solutions. Still, that does not give me reason to dismiss their more scientific conclusions. If I am going to differ from those, I need better science on my side, and I need to be able to show it.
A lot of people do not want to admit it, but when it comes to the Covid-19 pandemic the elites, by and large, actually got a lot right. Most importantly, the people who got vaccinated fared much better than the people who did not. We also got a vaccine in record time, against most expectations. Operation Warp Speed was a success. Long Covid did turn out to be a real thing. Low personal mobility levels meant that often “lockdowns” were not the real issue. Most of that economic activity was going away in any case. Most states should have ended the lockdowns sooner, but they mattered less than many critics have suggested. Furthermore, in contrast to what many were predicting, those restrictions on our liberty proved entirely temporary.

Who needs a UBI?
CDPAP’s enrollment, workforce and total costs ballooned after the state relaxed eligibility rules in 2015. The number of people receiving care through the program surged from just under 20,000 in 2016 to almost 248,000 last year. New York state Medicaid spending on CDPAP in the last five years has more than tripled to about $9.1 billion.
New York needs to make changes to the program, which Hochul called “wildly expensive.”
…Jobs in home health make up an increasingly large share of the city and state’s overall economy. Between 2014 and 2024, home health aide jobs went from comprising 6% of New York City’s total private-sector jobs to 12%, according to Bill Hammond, the senior fellow for health policy at the Empire Center for Public Policy, a fiscally conservative think tank.
I am not sure all of these numbers fit together, and am not sure that the actual percentage of private sector jobs is 12 percent. Nonetheless, the growth here seems quite rapid. Here is more from Laura Nahmias at Bloomberg.
It’s happening, UAE edition
The United Arab Emirates aims to use AI to help write new legislation and review and amend existing laws, in the Gulf state’s most radical attempt to harness a technology into which it has poured billions.
The plan for what state media called “AI-driven regulation” goes further than anything seen elsewhere, AI researchers said, while noting that details were scant. Other governments are trying to use AI to become more efficient, from summarising bills to improving public service delivery, but not to actively suggest changes to current laws by crunching government and legal data.
“This new legislative system, powered by artificial intelligence, will change how we create laws, making the process faster and more precise,” said Sheikh Mohammad bin Rashid Al Maktoum, the Dubai ruler and UAE vice-president, quoted by state media. Ministers last week approved the creation of a new cabinet unit, the Regulatory Intelligence Office, to oversee the legislative AI push.

England and Wales fact of the day
A recent survey, commissioned by the Bible Society and conducted by YouGov, showed 16 per cent of those aged 18 to 24 in England and Wales said they attended church at least monthly, significantly up from 4 per cent in 2018.
Here is more from the FT. Addendum: The above quotation from the FT is slightly misleading. Both numbers are the percentages for those who self-report as Christians.
Intertemporal substitution (from my email)
From a Czech newspaper:
Recruitment of new recruits in Russia is skyrocketing. With the prospect of a ceasefire, they want to ‘jump on the last train’
The number of Russians who have decided to join the army has multiplied in recent weeks. Regardless of their health, recruitment centres are taking anyone who expresses an interest. And it is growing even as an increasing number of Russian soldiers return from the front line in coffins. This is mainly due to the high rewards, and with the prospect of a ceasefire, the motivation of new recruits is even higher. Many of them hope to collect money and peace of arms will come before they end up on the front line.

Is China the ultimate free-rider?
With a Trump-induced decline of American alliances n the works, is Chinese global ascendancy going to result? It would seem so. Matt Yglesias tweeted that “America may be cooked and it’s gonna be the Chinese century.” Thomas Friedman recently wrote a column suggesting that the future is to be found in China, not America.
In the realm of technology, China’s advances are impressive. BYD has the best and cheapest electric vehicles, the CCP is pulling out all stops to attain high-quality chips and lithography capabilities. Chinese AI, in the form of DeepSeek and Manus, has shocked many Westerners with its inventiveness.
Yet Western and most of all American hegemony is not over yet. These advances by China are real, but they rest on a foundation of Western values and institutions more than it might appear at first.
Consider global economic growth over the last few decades. China has risen in import, relative to most of the poorer nations it was once bunched with. America too has risen in economic influence, widening the gdp gap with Western Europe. The lesson is that economies with scale have prospered more than average, which is hardly surprising in a world where tech and also big business are ascendant. America and China are thus likely to prosper jointly under broadly common conditions.
The inconvenient truth, for China, is that its scale relies upon American power and influence. The Chinese export machine, for instance, requires a relatively free world trading order. The recipe to date has been “mercantilism for us, free trade for everybody else.” Yet Trump threatens to smash that framework. If the world breaks down into bitterly selfish protectionist trading blocs, China will be one of the biggest losers. After all, where will the Chinese sell the rising output from their factories?
The Chinese growth and stability model also requires relatively secure energy supplies. For that it relies on the United States and its allies, as the Chinese programs for nuclear and solar power remain far from their final goals. If the Western alliance system collapses, who is to keep the Middle East relatively stable, at least stable from the point of view of procuring fossil fuels? China hardly seems up to that task, as the country has neither the means, the inclination, the experience, nor the allies to do the job.
Furthermore, China relies more on American hard and soft power more than it likes to let on. The leading role of America makes both Western Europe and also Latin America a bit “soft” when it comes to self-defense and martial spirit and also nationalistic pluck. After all, many countries are outsourcing their defense and also parts of their intelligence-gathering to the United States. That makes them relatively easy pickings for Chinese infiltration, whether it be economic infiltration, pulling up alongside as an easy “extra friend” to boost bargaining power with America, or spying and surveillance. If Trump scuttles our current multilateral commitments and trust, China will find most other countries harder to penetrate, not easier.
Another risk on the horizon is nuclear proliferation, which could result from any number of events, ranging from an Israeli attack on Iran, the partial fall of Ukraine, or a Chinese invasion of Taiwan. The more nuclear powers inhabit the world, the more China is hemmed in with its foreign policy ambitions. That outcome may not be good for the United States either, but again we are back to the scenario where the US and China have some fundamental common interests, rather than the narrative where China displaces America as world leader.
There is much to rue in the first few months of Trump’s foreign and economic policy, but China is far from being able to take the baton. They are running second, and doing a great job of that, precisely because we Americans – in spite of all our mistakes — still have the lead.
My interview with Times Radio
Times of London that is:
What should I ask John Arnold?
Yes, I will be doing a Conversation with him. John might be the smartest person I know about the energy sector and also about philanthropy. Here is the opening of his Wikipedia entry:
John Douglas Arnold (born 1974) is an American philanthropist, former Enron executive, and founder of Arnold Ventures LLC, formerly the Laura and John Arnold Foundation. In 2007, Arnold became the youngest billionaire in the U.S. His firm, Centaurus Advisors, LLC, was a Houston-based hedge fund specializing in trading energy products that closed in 2012. He now focuses on philanthropy through Arnold Ventures LLC. Arnold is a board member of Breakthrough Energy Ventures and since February 2024, is a member of the board of directors of Meta.
So what should I ask him?
