Has Trump pulled off the equivalent of a politically impossible global carbon tax?

Well, certainly not on purpose! He almost certainly thinks he is advancing the agenda of nominally US-based multinational oil companies. But by limiting the supply of oil and gas world wide, he has at least temporarily brought about the peak oil scenario that seemed to be fashionable a decade or two ago, and then mostly forgotten as it looked like new fossil fuel discoveries and exploitation technologies, along with non-fossil-fuel technologies, might outstrip any hard limit in the (economically viable) geologic supply.

But now we get to find out what an actual hard limit on supply looks like. It won’t be permanent – we can speculate months to years. But electrification technology was already a snowball rolling downhill in Asia, and this will just accelerate the takeover of electric vehicles, even if effective propaganda is hiding this from the U.S. public. Governments like Thailand’s are making rational policy choices such as incentivizing trade-in of internal combustion engines for electric. The economic incentive to do this is there, and has been slowed down until now only by infrastructure lock-in and path dependence. Even if this disruption is measured in months or years, the technology will continue to progress even in that time, and rational governments will realize this shut-down situation can happen again in the future and that they can mitigate the risk. So thank you to the one-man wrecking ball who has made all this short-term pain (i.e., horrible suffering and death for many, many human beings which I don’t mean to make light of) and long-term gain possible! (Now, you could say, and I admit, that with electrification coal will be substituted for oil and gas in the near to medium term, and this is not a win for the environment. I actually don’t know if it is a net win or loss, when you consider the greater efficiency of electrification over mobile internal combustion engines. But the incentives still favor renewables longer-term, and the incentives get stronger and stronger as renewables continue to get cheaper while coal as far as I know does not.)

A coalition of the willing implementing an international carbon tax is still a theoretical possibility. Here is one article on what that could look like. It is hard for me to imagine politically, but let’s say a group of large non-oil-producing economies, led for example by China, India, and the Asian Development Bank, decided they were going to do this and impose equivalent border-adjustment taxes (legal under the WTO I think not that this seems to matter any more) on all trading partners not doing it.

An international plan for sustainable development

International cooperation on climate and taxation remains inadequate to deliver decarbonisation, reduce poverty, and finance sustainable development at the required scale. We propose a Sustainable Union among willing countries, combining carbon pricing, new taxes on wealth, polluting fuels, financial transactions, and corporate income, with international revenue-sharing and conditional cooperation mechanisms. Most revenues would remain with participating governments for domestic spending, while a defined share would be pooled internationally. Specifically, participating countries would contribute 1% of gross national income (GNI) to a common pool redistributed in proportion to population, generating net transfers from richer to poorer countries. Meanwhile, the remainder of the revenue would increase domestic fiscal space by on average 2.2% of GNI. Although politically ambitious, such a framework might be credible, as governments are already advancing related forms of voluntary cooperation, and survey evidence indicates that it would be supported by majorities worldwide.

SimCity in space

Planetizen has a nice post on city-building games other than SimCity. I’m looking for a birthday gift for a kid who loves Minecraft and is interested enough in science to maybe add a little more hard sci-fi into the mix. The kid of mention is super smart and just not a reader – believe me, I’ve tried. I feel a little guilty giving kids these days more screen-based stuff, but then again I figure birthdays and Christmas are when you give them the things they want that you feel just a little guilty about.

Anyway, two games that are mentioned are Surviving Mars and Aven Colony, both space colony building games, the first looking like pretty hard science and the second more fantasy. These are both on Steam which we already have. From a little more research, Satisfactory is a less serious game but people seem to love it. So I have a bit more thinking to do and a choice to make.

The technological republic?

Below is the Goodreads description of The Technological Republic: Hard Power, Soft Belief, and the Future of the West, by Palantir’s CEO. I also read the summary of it posted by the company on X. It’s a lot of words that don’t add up to a lot of meaning, in my opinion, but my cynical synopsis is “The USA is exceptional and morally pure. AI and surveillance technology are the new weapons of mass destruction. Pay us to build them before our enemies (which is pretty much everyone else, because we are exceptional and morally pure) build them first and attack us with them. Our morally pure public service will be to get rich selling weapons and surveillance technology to the US government, and yours will be to sacrifice your children with a smile on your face when we draft them and send them to fight holy wars against our enemies.”

Silicon Valley has lost its way.

Our most brilliant engineering minds once collaborated with government to advance world-changing technologies. Their efforts secured the West’s dominant place in the geopolitical order. But that relationship has now eroded, with perilous repercussions.

Today, the market rewards shallow engagement with the potential of technology. Engineers and founders build photo-sharing apps and marketing algorithms, unwittingly becoming vessels for the ambitions of others. This complacency has spread into academia, politics, and the boardroom. The result? An entire generation for whom the narrow-minded pursuit of the demands of a late capitalist economy has become their calling.

In this groundbreaking treatise, Palantir co-founder and CEO Alexander C. Karp and Nicholas W. Zamiska offer a searing critique of our collective abandonment of ambition, arguing that in order for the U.S. and its allies to retain their global edge—and preserve the freedoms we take for granted—the software industry must renew its commitment to addressing our most urgent challenges, including the new arms race of artificial intelligence. The government, in turn, must embrace the most effective features of the engineering mindset that has propelled Silicon Valley’s success.

Above all, our leaders must reject intellectual fragility and preserve space for ideological confrontation. A willingness to risk the disapproval of the crowd, Karp and Zamiska contend, has everything to do with technological and economic outperformance.

At once iconoclastic and rigorous, this book will also lift the veil on Palantir and its broader political project from the inside, offering a passionate call for the West to wake up to our new reality.

Where are we on longevity?

This is a long excerpt from Peter Diamandis’s book We Are as Gods: A Survival Guide for the Age of Abundance. The New York Post somewhat amusingly did not proofread and reports the subtitle of the book as “A Survival God…” – maybe they will correct before you read this? Or maybe nobody knows or cares. Anyway, it’s sort of a cheerleading piece but I found it interesting for a run-down of some of the longevity drugs and technologies that are out there:

CRISPR lets us edit the genome; Yamanaka factors, a set of four transcription genes, roll back the biological age of cells; cellular reprogramming, epigenetic editing, mitochondrial enhancement. Each of these technologies adds more possibility, and all of them are being accelerated by AI.

Enter senolytics, a new class of drugs that clears zombie cells from our system. In mice, they’ve already extended healthspan and lifespan. Human trials are underway.

Meanwhile, companies like Celularity are working on immune reinforcement. Founded by stem cells pioneer Robert Hariri, Celularity harvests NK cells from healthy placentas and transfers them into aging bodies, where they bolster immune function. They’re also developing T cell and stem cell supplements to reboot the body’s natural repair systems. Together, these advances shift the paradigm from treating age-related disease to preventing decline before it starts.

It goes on like that, and kind of transitions from the academic research to sales pitches for various companies. Probably some of their stuff will work out and some will turn out to be snake oil.

Is Russia really a match for western Europe economically or militarily?

Here’s some fun with the CIA World Factbook, courtesy of Gemini, not fact-checked by me. This might have taken me at least half an hour to an hour to pull together in the past, which means I probably wouldn’t have done it today given other things I have to get to. Anyway, I hear suggestions that Russia is going to inevitably attack western European countries. That just doesn’t make any sense. Russia is a military power only because it spends 7% of its GDP on the military, and at the moment its military is battle-hardened from recent conflict. Very roughly speaking, its military spending is on the order of double the UK, France, or Germany (any one of those). But the GDP of any one of these western European countries is on the order of double Russia’s GDP. So attack them directly, and Russia might have a short-term advantage but they will be able to overwhelm Russia over time. That’s any one. If those three countries stick together, they can steamroll Russia once they get into a war economy mode. And add in the rest of Europe or NATO not including the US, and the comparison is laughable. Add in the US, and Russia would be fighting a literally an order-of-magnitude larger enemy. So maybe, as some are suggesting, Russia would consider attacking a small NATO country like Estonia or Finland, but it seems like a huge gamble to me. And they seem to be pretty coldly rational to me. It’s seems more likely they will try to consolidate their control over the remaining non-NATO eastern European countries, and be content that they have stopped the eastward expansion of NATO dead in its tracks for the foreseeable future if not for generations. This last was probably their primary objective in attacking Ukraine, and it has been achieved.

April 2026 in Review

In fast-moving current events as I write (Saturday, May 2), active so-called “kinetic” warfare seems to have subsided in and around Iran. Let’s hope the trend continues in this hopeful direction. Human rights violations elsewhere and global economic impacts persist.

Most frightening and/or depressing story: We have heard horror stories about U.S. government debt over the decades, many not grounded strictly in evidence. But this time really seems to be different, where the absolute size of the debt at the moment means higher than normal interest rate payments as a fraction of the economy and tax revenue. At the risk of stating the obvious, this means the government has less money for things other than interest payments. Meanwhile the trends are increasing debt level, increasing interest rates, and potentially lackluster economic and tax revenue growth, all pointing toward a runaway train. Hoping for a pickup in economic growth seems to be the main strategy being pursued to counteract this feedback loop.

Most hopeful story: AI science seems to have a theme of mine in April. We can constraint an AI scientist to actually respect the laws of physics, potentially accelerating scientific and technological progress. AI should also be good at synthesizing past research to form a basis for future progress, and organizing data in an accessible way so that others (human and/or AI) can confirm findings or make new discoveries from that same data. I know some very nice people who work in today’s academic publishing industry, but this may not be an area of rapid future growth. The future of engineering and scientific modeling will probably consist of giving an AI a very detailed specification for what you want it to accomplish, then reviewing/validating the result when it comes back.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: Augmented (aka mixed) reality glasses are getting pretty common in China, and slowly catching on elsewhere. Early adopters include cheating students, of course.

methylsiloxanes

All we have to do is look, and we find more “forever chemicals” all throughout the environment and our bodies. This just adds to my suspicion that classes of chemicals like PFAS and microplastics (and before that lead, DDT, etc.) might not be the most pervasive or dangerous chemicals out there, but merely the ones we have put under the magnifying glass so far. Similarly, we put the Covid-19 virus under many microscopes for many years and found all kinds of things it does to our bodies and brains. But if we put similar scrutiny on other microorganisms, who knows what we might find?

A new study shows that a specific type of silicone, the so-called methylsiloxanes, is widely present in the atmosphere across diverse environments. Also, concentrations appear to be much higher than expected. According to the researchers, this raises concerns about their potential—yet poorly understood—effects on human health and the climate. Methylsiloxanes are commonly used in industry, transportation, cosmetics, and household products. The study was supervised by Utrecht University and the University of Groningen, and the results are published in Atmospheric Chemistry and Physics.

I’m probably a broken record on this, but chemistry really does make our modern lives safer and more convenient overall. Without water disinfection, food preservatives, antibiotics, vaccines, dental anesthesia, etc., our lives would be nasty, brutish, and short indeed, as they were before we had those things. We don’t want to give up the benefits of useful chemicals, but we also should always be searching for non-toxic alternatives that give us the same benefits.

vehicle-to-grid (or detachable, mobile batteries)

That’s right, your electric car could theoretically serve as a battery for your electric house that can detach itself and move around during the day. Not only that, but you could theoretically sell energy back to the grid – “vehicle to grid” – that you don’t need during times of peak demand. It all makes a lot of sense, although predictably the US grid is not up to date enough to fully support this. We can be hopeful though that utilities will make rational choices as they look at grid updates and vehicle-to-grid policies vs. building new generation capacity.

Of course, if mobility is going to be more of a convenient on-demand service as opposed to buying a machine that puts me in debt and takes up a quarter of my house, I personally would rather buy the battery without the vehicle. In fact, if it is profitable to do so, I don’t see why a group of homeowners or investors wouldn’t get together and invest in a battery farm. Or how about a battery+data+solar farm? So it seems to me that if this policy change is made, it could drive significant change in behavior and physical infrastructure.

robots and sidewalks

We’re starting to see those Uber Eats robots on the sidewalks here, and they are spurring some renewed interest in the poor state of the city’s sidewalks. Now, I am surprised they don’t just design the things with bigger tires, as many parents have figured out that a “jogging stroller” can navigate our decrepit streets much better than a stroller with small tires designed for a fully ADA-compliant mall.

Anyway, since sidewalks here are the legal responsibility of private property owners, it occurs to me that Uber could start suing people if they wanted. It seems they would have a valid argument of economic damages. And trip-and-fall lawsuits, or the threat thereof, are a primary motivator of the sidewalk repairs that do happen, as this article in The Philadelphia Citizen points out.

But other cities have figured out better ways, which the article has a nice run-down of:

The 2022 ordinance enabled a straightforward deal: The City of Denver assumed all responsibility for sidewalks in exchange for property owners’ financial support. Denver began collecting a $150 annual fee from property owners and putting it towards citywide sidewalk maintenance. Last summer, Denver announced $75 million in repairs and construction from that fund.

Denver is a bold example, but it’s not alone. In many cities, residents don’t have to shoulder the full burden of sidewalk repairs. Chicago has a popular “shared cost sidewalk program” that has been running for decades and uses City resources to incentivize property owners to repair pedestrian walkways. Citizens pay a maximum of $2,400 — and typically around $1,000 — to participate, costs which are comparable to what a private contractor would charge. Cities like San Jose, NM and Memphis, TN have similar shared-cost programs.

And then there’s Washington, D.C., where a 6-year, $115 million effort to improve sidewalks is underway. The local government established a goal of building 8 miles of new sidewalks each year and repairing up to 40 miles of existing ones — work that aims to satisfy both the Vision Zero initiative and the Office of Disability Rights’ Olmstead Plan. In D.C., the land between a property and the curb is publicly owned, making it easier for the government to intervene. But the decision to prioritize sidewalks and enact a cohesive plan are actions that every city could seek to emulate.

Of course, people hate new taxes, and are only partially fooled by not-even-tax-deductible taxes disguised as service charges and fees. There’s also a complex issue this article doesn’t go into, which is that by making private property owners legally responsible for obviously public sidewalks, the city also makes them legally responsible for arguably public infrastructure underneath such as water, sewer, and gas pipes. But the point is that these programs solve a problem and give us value back in a more efficient manner than the non-system we have now.

Academic publishing beyond the current citation regime

This blog post from someone named David Oks pines for a time before citations became a central pillar in the effort to advance scientific publishing. Thank you Mr. Oks for sharing your views, which got me thinking. I am not sure I agree 100%, because an important part of civilization and science is our ability to document the state of knowledge so that each successive generation can build on it. But the point is taken that the extreme focus on gaming this one metric (number of citations, citation scores of individual academics and journals) has become an end in itself, rather than a means for advancing civilization and science.

I do think AI can be very good at improving the state of the “literature review”. Every scientific article starts with a summary of literature on the topic, which the authors then typically build on (although, some articles are just literature review). A human author can spend years sifting through a vast amount of literature relevant to a topic, particularly a novel or interdisciplinary topic, trying to find those few needles in a haystack that are really the most, say, 100 highly relevant papers, and synthesize them into a foundation that can be built on it. I have done this, and it is actually a very fun thing to do (for my personality type, I suppose, not for everyone, but there are many like me…) Through this process, you gradually build and refine your own unique mental model on a subject which then can become the foundation for your personal unique contribution to human progress. However, even spending years, you can’t come close to looking at everything possibly relevant, and you can miss some of those needles. An AI should be able to look at literally the entire haystack, find and synthesize the needles, in a matter of minutes or at most hours, compared to months or years for a person. The only sad thing here is that the best mental models in the brains of the smartest humans might not be built in the same way. Overall though, I suspect the rate of progress can be increased significantly.

What is an alternative to the citation regime according to Mr. Oks?

So I suspect that we’ll have to fundamentally rethink the institutions of scientific life for the age of strong AI. Perhaps, as AI makes it possible to do much more science much more quickly, the culture of science will become more like the culture of engineering—faster, more collaborative, less interested in priority claims. In such a world, the most efficient unit of scientific contribution might be a living document, perhaps even just a GitHub repo: something with data, code, analysis, and a thin narrative layer that AI scientists could read, regenerate, or update as needed. And citations, in this world, could ultimately become obsolete. Journal articles would survive, though perhaps they’d become something closer to definitive pronouncements on major breakthroughs or on the state of knowledge in a given domain—a bit like what scientific books were before the rise of journals. In a world where science is much more productive than it is today, legitimacy will be the scarce factor in the production of useful scientific knowledge.

I am not sure I have experienced the culture of engineering described here in my own engineering career, but this may be referring to something more like “product development” rather than the public infrastructure and environmental planning type work I do. Anyway, my idea of AI-backed knowledge synthesis plus this idea of open data and code may be on to something.
