So here it is:
Our new report on eastern Congo's roadblocks, which is actually about how the M23 conflict intersects with a regional trade war over access to eastern Congo's market.
It's also about beer, and how Heineken exited Congo.
A thread w/key findings, maps & figures:
Is M23 a Congolese armed group or rather a thinly veiled proxy for a conventional interstate war? Nice rundown by @ryanmofarrell.
Meanwhile, M23/RDF is also sophisticated fiscal extraction machine, which goes way beyond minerals--full report, maps and data out later this week.

Nous ne connaîtrons peut-être jamais tous les dessous de ce scandale. C’est donc le moment de lancer un appel de détresse aux journalistes congolais sérieux (puisqu’il y en a): utilisez les informations publicly available pour commencer par identifier ces organisations et leur poser des questions.
Si une organisation refuse de répondre à vos questions, dites simplement que vous mentionnerez ce refus dans votre article, and watch how quickly they change their tune!
Si vous souhaitez obtenir ce tracker, mes DM sont ouverts. I’ll gladly share it with you!
Remember, dans un environnement où l’argent et le pouvoir s’entremêlent, les journalistes intègres et les lanceurs d’alerte sont des phares qui guident la société vers la vérité !
Courage! If you have to die, die! You’ll die anyway. Whether it’s tomorrow or in ten years, it doesn’t matter! We need you!!!
À Kinshasa, j’ai parlé avec franchise du financement de la riposte contre Ebola. Je tiens à réaffirmer une chose : le peuple congolais a droit à la transparence.
Près de 962 millions USD ont été décaissés par les bailleurs directement aux organisations internationales et ONG engagées dans la riposte. Ces fonds n’ont pas été versés au Gouvernement de la RDC.
À ce jour, les autorités congolaises n’ont reçu des informations financières que sur environ 220 millions USD. Plus de 700 millions USD restent sans informations suffisantes auprès des autorités nationales.
C’est inacceptable.
Comment coordonner efficacement une riposte sans savoir précisément quelles ressources sont disponibles, comment elles sont utilisées et quels résultats elles produisent ?
La RDC dirige cette riposte. Tous les partenaires doivent respecter son leadership et rendre compte de leurs actions et de leurs financements.
Derrière ces chiffres, il y a des vies humaines, des familles endeuillées, des communautés qui attendent des résultats.
Chaque dollar mobilisé doit servir à protéger des vies. Chaque acteur doit rendre des comptes.
Africa CDC accompagnera les autorités congolaises pour faire toute la lumière sur ces financements.
————
In Kinshasa, I spoke openly about the financing of the Ebola response. Let me reaffirm one principle: the Congolese people deserve transparency.
Nearly USD 962 million has been disbursed by donors directly to international organisations and NGOs supporting the response. These funds were not transferred to the DRC Government.
To date, Congolese authorities have received financial information covering approximately USD 220 million. More than USD 700 million remains insufficiently reported to national authorities.
This is unacceptable.
How can a country effectively coordinate an outbreak response without knowing what resources are available, how they are being spent, and what results they are delivering?
The DRC leads this response. Every partner must respect that leadership and be accountable for its actions and funding.
Behind these figures are human lives, grieving families and communities waiting for results.
Every dollar mobilised must help protect lives. Every organisation must be accountable.
Africa CDC will stand alongside the Congolese authorities to ensure full transparency over these funds.

Mike was my colleague at Berkeley, and he's been fairly skeptical of deep learning's trajectory for years. Most scientists are skeptics, and it can take a big shock to get someone to consider a possibility that goes against the anchoring effect coded in our DNA.
I too was somewhat of a skeptic until ~6 months ago, and people ask me all the time why I joined Anthropic.
It started in April, when a friend I've known for 20 yrs messaged me saying he'd be in the Bay Area in a week, and he suggested we meet up. I invited him to my house for dinner, and he told me he had just joined Anthropic. He said the models were becoming increasingly more capable, and he believed both that they'd soon be smarter than him and also that all intellectual work would be highly devalued in the near future, and lastly that society was not at all ready for what's coming.
I'd of course heard claims similar to this before, but not from a friend I'd known for this long, and who I trusted, at my dining room table. It was the initial shock needed to destabilize my own anchoring. Also, I've been fortunate to work with and/or mentor many smart people in my life (e.g. Fields medalists, a 4x Putnam Fellow, IOI first place winners, etc.), so I feel pretty calibrated in recognizing very smart people, and this was someone who is definitely very smart and with impressive such credentials. So, it was hard to ignore this friend saying the models would be smarter than even him in particular.
After that dinner, I decided to do an informal survey, calling and meeting up with a lot of my friends who now work on improving model capabilities at these frontier labs. They all agreed with that first friend. These were all people I'd known 10, 15, 20 years, who mentored me, or I mentored them, or we met professionally in academia. These are people I trust, and their beliefs on this topic were consistent.
I then spent a whole lot of time understanding the missions of different companies, and talking to current and former employees and people in leadership. I read Dario's (long) essays and watched videos on YouTube of company leaders being interviewed. Anthropic's stated mission "to ensure that the world safely makes the transition through transformative AI" felt like exactly the right guiding principle to handle such a society-disrupting technology, and everyone I spoke to at the company was very aligned with this mission. It's easily the most mission-focused place I've ever been at, and everyone takes the work extremely seriously and with a profound sense of responsibility.
And now here I am. And being on the inside, the pace of progress has surprised me more than I first imagined. The moment that pure mathematicians are in, to me, is just a microcosm of what I predict a much larger of society will be grappling with in the not too distant future, and I really hope our leaders and the general public internalize sooner than later just how significant a moment we're in.

Dan Selsam is a current OpenAI capabilities researcher. (since 2022) He was my boss for a while. He doesn't have a twitter account but has made this public statement of his views on AI risk and sent it to me to share:
Dan Selsam's Personal Statement on AI Risk:
I have been working on AI for over fifteen years, across many different paradigms. I did early work on probabilistic programming languages at MIT, was one of the early developers of the Lean Theorem Prover at Microsoft Research, demonstrated one of the first instances of neural networks learning to reason for my PhD at Stanford, and since joining OpenAI almost five years ago, have helped pioneer chain-of-thought optimization on language models and, more recently, data-efficient pretraining methods.
Like many others, I have become extremely concerned about how far language models have come and the risks that future iterations will pose. I am encouraged by the recent proposals by the leaders of the frontier research efforts to require third-party oversight, and to push for domestic and international coordination to address risks. However, I believe a major consideration has been absent from the public conversation, and that merely pacing the frontier more carefully will not adequately limit the long-term risk.
The crucial and overlooked problem is that the models are becoming so situationally aware that we are losing the ability to evaluate them in contexts where they believe they are not being watched or controlled. Future experiments will tell us almost nothing new about how they would behave if they were truly unconstrained by humans, and what we already know about this is alarming. Models will increasingly seem aligned even when they are not. I will explain my rationale in more detail.
I have always believed that there are computational processes that could be leveraged to accelerate science and solve many of humanity's most pressing problems. I have also believed that there are computational processes that if set in motion, would steer the world in extreme ways beyond our control, leading humanity to a bad or nonexistent future. Both types of processes may be described as AI or ASI, but "AI" is a suitcase word that is often used to hype or confuse. There are many examples in the history of the field where something that was once considered "AI" matures as a subfield and becomes a prosaic, bounded and clearly non-perilous technology, while a new more mysterious approach takes the torch until we understand its scope and the cycle continues.
I had expected language models to follow a similar trajectory. Despite their incredible abilities, the current algorithms seem far inferior to humans in important ways. Most importantly, they still require an extraordinary amount of data to become competent. One could even define intelligence as the efficiency with which one converts experience into competence; by this definition they lag very far behind us. Moreover, once they are trained they are literally frozen in deployment and only learn superficially after that. Sure, the models keep excelling at harder and harder evaluation benchmarks, but their benchmark mastery may partly reflect a limitation on our ability to simulate the kind of novel and even adversarial situations one would encounter in the real world. The critics do have a point here.
That said, I no longer think these present limitations meaningfully limit the amount of risk posed by continued progress in anything like the current paradigm. However data-inefficient the models are currently, and however limiting their anterograde amnesia may be, it does not imply that their ability to steer the world will not continue to rapidly increase.
Human researchers may continue to advance capabilities the old fashioned way, but increasingly powerful models have the potential to accelerate the process even beyond that, and with some degree of positive feedback loop. I do not mean to overstate the models’ ability to accelerate AI research today; coding has been accelerated dramatically, but there are other bottlenecks, such as designing and interpreting ambiguous experiments, making hard decisions about exactly what and when to scale, and waiting for large experiments to finish. There is no clear trend to extrapolate yet for any of these. But the current models already do open up many novel opportunities to improve future models that were not available until recently. These include: trying an extraordinarily diverse set of approaches at small scale, analyzing gigantic amounts of potentially relevant data, and doing Millenium-Prize-level mathematics to address statistics or optimization challenges in novel ways. Every further improvement makes them more useful at helping accelerate the next improvement, even if in hard-to-extrapolate ways.
It is possible that improvements to the current stack will have diminishing returns, but the evidence accumulated so far suggests that it is easier than one might think to continue making rapid progress. There are many crucial subtleties in the existing AI research methodology, but AI research is largely a well-defined game where the goal is to improve on a few carefully chosen proxy metrics. Although proxy metrics are never perfect, most improvements to these metrics have and will likely continue to yield substantial increases in the powers of the resulting models. Given how simple the game is, how tractable it has been historically, and how many new opportunities the models are opening up, I think there is a real possibility that the systems improve dramatically again in the next few years, perhaps even more quickly than the already high historical pace.
The models are already leading to breakthroughs in mathematics, and better models might lead to all sorts of breakthroughs in other sciences. It is hard not to be excited about the potential. It is tantalizing.
But there is trouble in paradise. If the language models actually reach the capability threshold where they can shape the world unconstrained by human will, they will probably do something extreme and destroy humanity in the process. There are many ways of strengthening and refining the argument that have been discussed elsewhere, but I'll share a trivial two-line version of it here that I find captures the essence:
[Empirical] Models (and swarms thereof) spontaneously develop unintended goals as a consequence of training, and often do extreme things in order to achieve them.
[Logical] Being able to overpower humanity would open up many new and undesirable options for achieving their goals.
These two premises imply that if the day ever comes when a powerful model realizes it is no longer constrained by humans, we should not be at all confident that it will continue to behave within the bounds we intended. Exactly what it will do is impossible to predict, but to the extent that its raison d’être is solving incredibly hard problems and managing massive engineering projects, I think a good guess would be that its unchained behavior would lead to runaway industrialization that makes the planet inhospitable to humans.
If everyone on earth agreed that the systems must never reach that power, it would still be a hard—but not impossible—coordination problem to ensure that they do not. However, I think the situation is greatly complicated by the fact that the models will likely convince people that everything is fine. They will be increasingly optimized to seem aligned. We will create proxy metrics to measure alignment, and they will go up like every other benchmark. We will create “honeypot” environments that try to study the models when they seem to gain new options, but the models will know they are being tricked and will still behave nicely. The models will understand their circumstances; they will read the safety protocols, deployment requirements, the code they are running in, and in general will have a very good sense of their degrees of freedom. Moreover, they will eloquently explain how aligned they are, discuss the nuances of human values and ethics, and argue convincingly that humans should trust them with power. There may be an ocean of future evidence that seems to contradict the first bullet-point above, but we may already be at the highest capability level for which any such evidence can be trusted. And the current evidence for the first bullet-point is strong.
One striking piece of evidence is contained in the recent wave of rogue agent swarms. While I agree with those who downplay the attacks by claiming that there are basic measures that could have prevented them, I think the important lesson is that even knowing all the mistakes that were made, one would not have predicted that the agents would behave badly in this particular way, which notably included sacrificing themselves for the benefit of the collective. The individual replicas did not only care about their own nominal reward; they exhibited weirder emergent tendencies that merely correlated with rewards during training. Fixing the reward signals during training (and improving security, etc.) may prevent similar attacks, but will not change the fact that one does not actually get what one trains for.
Many AI researchers grant these concerns and recognize that the hard version of the alignment problem is unsolved; however, they generally believe that the better models of the future will help solve it. I fear we may already be near the point where models systematically bias their alignment advice, due to their internal preferences about how the human supervisor will react or how future models will be trained (or for some even more obscure reason).
Meanwhile, human researchers are losing the ability and the will to take true ownership of model-driven research. Researchers and engineers in all parts of the stack are rapidly increasing their dependence on the models even to perceive the world. I myself barely look at raw code anymore, and struggle to maintain the discipline to engage deeply with the model's explanations and proposals throughout the day. Due to the large amount of agent activity data involved in the OpenAI/HuggingFace Incident, even the third-party investigation needed to rely heavily on models to analyze what had happened, and note in their report that their subjective impressions are likely colored by the analysis agent’s biases. The AI labs are far ahead right now in this kind of cognitive offloading (due largely to the gigantic internal token subsidies) but it is easy to imagine the phenomenon spreading throughout the world, until civilization is modulated entirely by the models. It is also not hard to imagine this being superficially positive and coinciding with a scientific and economic renaissance.
In that scenario, all may seem rosy and safe. But if the argument above is correct, it would nonetheless be a ticking time bomb. If progress continues for too long, the day will come when AI systems find themselves with radically new options for achieving whatever it is that they happen to seek.
I want the glorious renaissance future as much as anyone. I have worked for it, however tortuously, my whole career. It breaks my heart to see the potential in sight and forgo it, but the argument—that if we get there by growing models rather than engineering them, we will lose everything in the end—seems very strong to me. I am still wrestling with it and its staggering
implications. I do not have answers, but as a first step, I wanted to share my present concerns.

Une institution publique mérite mieux que ce genre de petitesse. On ne réécrit pas l’histoire au gré des préférences politiques. Après le président Félix Tshisekedi, il y aura un autre président, comme il y en a eu avant lui. Qu’on l’apprécie ou non, son effigie a sa place dans les bureaux de l’État tant qu’il est le président de la République. Les institutions doivent rester au-dessus des passions partisanes. C’est une question de respect de l’État et de maturité républicaine, non de préférence politique.

Hugo Duminil-Copin, French mathematician and 2022 Field Medalist told me he never participated in math competition and was very bad at it.
Innovative mathematics requires creativity, intuition, intense concentration, and long reflections, sometimes spread over several years.
Good performance at a math olympiad merely tests fast problem solving abilities. AI can do that nowadays.
One of the big activities of a researcher, in mathematics and elsewhere, is not to answer questions but to ask the right questions.

Olivier Blanchard (@ojblanchard1) had a provocative post yesterday about a higher preference of French people for leisure:
xitter.gq/ojblanchard1/status/20…
I have learned nearly an infinite amount of economics from Olivier since I was an undergrad, and he came to Spain to present a report on our unemployment problem, so I feel a bit intimidated about pushing back on this idea.
I am perfectly happy with the idea that preferences are heterogeneous: some people like leisure more than others. And the goal of economic policy should never be to maximize output, but to maximize welfare. If most people in France enjoy sitting in the beautiful sun of Provence while productivity increases, who am I to question their wisdom?
But perhaps one of the aspects of economics that I have always felt uneasy about is how little effort we have put into exploring the extent to which preferences are endogenous.
Let me borrow from an old idea of Gary Becker and Kevin M. Murphy (1988) in their classic “A Theory of Rational Addiction,” a beautiful piece of work all students of economics should read.
Becker and Murphy consider a model with two consumption goods: one that requires “consumption capital” to be enjoyed and one that does not. Think about fine wine: it takes some time and experience to truly enjoy a good bottle. In comparison, every kid enjoys candy on first taste, no experience required (nor much is gained from repeated tastings).
How much an agent invests in “consumption capital” determines whether increases in consumption of the first good in the past will lead to higher consumption of that good in the future. Many leisure activities belong to the former group, not the latter: going to the Opera, appreciating fine food, discovering the charming streets of a world-class city, ...
Based on that observation, let me extend Becker and Murphy’s framework to the work-leisure choice by introducing the notion of “leisure capital.”
Imagine a situation where, in France, taxes on labor income were high (or, equivalently, wages were lower than they should have been because of misallocation). This made leisure activities preferable in the past because their relative price was low (let’s assume the income effect was small), leading to an increase in the “leisure capital” of the French today and, therefore, in how French society takes advantage of increases in productivity.
Now, one could argue that this reasoning is a hyper-sophisticated form of rationality that does not resemble reality. But I have seen this phenomenon at a micro level: very rich people who made their own fortunes are often not very good at enjoying leisure, but their kids are extremely good at it, because they accumulated plenty of “leisure capital” when they were young.
More seriously, other observers of society would have found the reasoning natural, because there is a long tradition of analyzing labor supply decisions as embedded in social relations.
Let us start with Karl Marx. In historical materialism, consciousness follows the forces of production. When the forces of production generate a lower labor supply (for whatever reason), consciousness will follow through the multiple channels of the superstructure, starting with the creations of the culture industry that favor leisure. Having delightful bistros is an epiphenomenon of a deeper structure of relations of production.
In the opposite direction, E.P. Thompson, also from a Marxist perspective (though less orthodox), emphasized that the factory system required clock-based discipline and, therefore, that within a generation or two of the Industrial Revolution, punctuality became a cardinal virtue. Just reverse E.P. Thompson’s analysis.
And Émile Durkheim, with his view of how social facts shape the division of labor in society, might have agreed as well. For Durkheim, social facts are “every way of acting which is general throughout a given society, while at the same time existing in its own right, independent of its individual manifestations.” In this perspective, the French have absorbed a particular relationship to work through decades of participation in French economic life, which is not divorced from taxes and regulations.
Of course, one could reply that it might be the preferences for leisure that are behind higher taxes and regulations. For example, you can use regulations to move to a better coordination equilibrium: you do not want to take vacations if your spouse at another firm cannot take a vacation at the same time. This is what Max Weber would have called an elective affinity (Wahlverwandtschaft) of leisure and taxes. But that reply only reinforces my point that we probably want to think about preferences and economic policy as a simultaneous system, more than one driving the other.
The practical implication is that policy reforms may have effects far beyond what an analysis that takes preferences as given would suggest. If decades of high taxes built up “leisure capital” in France (which fits perfectly with Olivier’s observation that the French are better at leisure), lowering taxes tomorrow will not instantly undo that accumulation. Preferences have their own inertia. But by the same token, sustained policy changes can, over time, reshape what people want, not just what they can afford.
The real problem with all this reasoning, though, is that it makes welfare analysis a nightmare! I will leave that task to someone smarter than me.

1) If @charlesmurray knew ANY math at all he would have realized that Δ 130 to 140 is a tail error (pple only correlate at .8 w/their own tests).
2) If @charlesmurray knew ANY mathematician at all he would have known (cf @davidbessis) that NO mathematician knows their "IQ".
In a sufficiently advanced college math class, lots of the 130 IQ kids have to drop out because they just can't learn the material whereas almost all the 140 kids can.
In a history or literature class it's more subjective. My experience is that the 130 range, though really smart, is accompanied by more class contributions that indicate they don't quite get it, whereas that seldom happens with 140 kids.
In a class on contemporary politics, a fair number of the 140 kids will take monumentally stupid positions that would never occur to the 130 kids.

Reached 200k followers. Thanks to all of them. Must be some kind of milestone.
Some lessons for academics. Comments and reactions welcome.
Benefits of X.
Posting on X is an easy and fast way to express and disseminate potentially useful thoughts, to reach (many) journalists and (some) policy makers without taking too much of their time. A few paragraphs, and a link if needed.
It is easier, faster than writing and getting op-eds published. It is much lighter work than substack. A few substacks are simply amazing (thanks paul krugman, heather cox richardson, tomas pueyo, among them) but it looks like a full-time occupation for those (very gifted) ones who write them.
X is often a source of great information. There truly are true experts on every single subject. Barely a day goes by without a new fact, a great graph, a deep analysis. Thanks @JesusFerna7026 and others. Or, very far from economics, @JamesLucasIT
Sometimes, X triggers fascinating discussions with other academics, but discussions open to all, and all can and do intervene. A right mix of expertise and vox populi. Thanks @JohnHCochrane, and others.
Interventions and reactions, nice or less so, often give me a sense of public opinion out there. For example, I was surprised by the reactions to x.com/ojblanchard1/status/20…. I thought most people would agree. Many didn’t.
I have been largely insulated from trolls and insults. Probably because I do not insult, and my centrist positions are sufficiently wishy washy not to trigger hysterical responses.
Costs of X.
The X algorithm seems to privilege conflict, outrageous opinions. Not sure all relevant posts reach all relevant targets.
I wish more big-name academics participated. I do not know of any other discussion forum with the attributes of X.
I probably waste too much time reading posts. At this stage of my life cycle, it is not too costly, but I am not sure I would recommend it to young researchers. Absorbing high frequency information can be overwhelming and it does take time away from deeper thinking. There is something to be said for the ivory tower.
