    This week we talk about in-game skins, investment portfolios, and Counter-Strike 2.We also discuss ebooks, Steam, and digital licenses.Recommended Book: Apple in China by Patrick McGeeTranscriptAlmost always, if you buy an ebook or game or movie or music album online, you’re not buying that ebook, or that game, or whatever else—you’re buying a license that allows you access it, often on a specified device or in a specified way, and almost always in a non-transferrable, non-permanent manner.This distinction doesn’t matter much to most of us most of the time. If I buy an ebook, chances are I just want to read that ebook on the device I used to buy it, or the kindle attached to my Amazon or other digital book service account. So I buy the book, read it on my ebook reader or phone, and that’s that; same general experience I would have with a paperback or hardback book.This difference becomes more evident when you think about what happens to the book after you read it, though. If I own a hard-copy, physical book, I can resell it. I can donate it. I can put it in a Little Free Library somewhere in my neighborhood, or give it to a friend who I think will enjoy it. I can pick it up off my shelf later and read the exact same book I read years before. Via whichever mechanism I choose, I’m either holding onto that exact book for later, or I’m transferring ownership of that book, that artifact that contains words and/or images that can now be used, read, whatever by that second owner. And they can go on to do the same: handing it off to a friend, selling it on ebay, or putting it on a shelf for later reference.Often the convenience and immediacy of electronic books makes this distinction a non-issue for those who enjoy them. I can buy an ebook from Amazon or Bookshop.org and that thing is on my device within seconds, giving me access to the story or information that’s the main, valuable component of a book for most of us, without any delay, without having to drive to a bookstore or wait for it to arrive in the mail. That’s a pretty compelling offer.This distinction becomes more pressing, however, if I decide I want to go back and read an ebook I bought years ago, later, only to find that the license has changed and maybe that book is no longer accessible via the marketplace where I purchased it. If that happens, I no longer have access to the book, and there’s no recourse for this absence—I agreed to this possibility when I “bought” the book, based on the user agreement I clicked ‘OK’ or ‘I agree’ on when I signed up for Amazon or whichever service I paid for that book-access.It also becomes more pressing if, as has happened many times over the past few decades, the publisher or some other entity with control over these book assets decides to change them.A few years ago, for instance, British versions of Roald Dalh’s ‘Matilda’ were edited to remove references to Joseph Conrad, who has in recent times been criticized for his antisemitism and racist themes in his writing. Some of RL Stine’s Goosebumps books were edited to remove references to crushes schoolgirls had on their headmaster, and descriptions of an overweight character that were, in retrospect, determined to be offensive. And various racial and ethnic slurs were edited out of some of Agatha Christie’s works around the same time.Almost always, these changes aren’t announced by the publishers who own the rights to these books, and they’re typically only discovered by eagle-eyed readers who note that, for instance, the publishers decided to change the time period in which something occurred, which apparently happened in one of Stine’s works, without obvious purpose. This also frequently happens without the author being notified, as was the case with Stine and the edits made to his books. The publishers themselves, when asked directly about these changes, often remain silent on the matter.What I’d like to talk about today is another angle of this distinction between physically owned media and digital, licensed versions of the same, and the at times large sums of money that can be gained or lost based on the decisions of the companies that control these licensed assets.—Counter-Strike 2 is a first-person shooter game that’s free-to-play, was released in 2023, and was developed by a company called Valve.Valve has developed all sorts of games over the years, including the Counter-Strike, Half-Life, DOTA, and Portal games, but they’re probably best known for their Steam software distribution platform.Steam allows customers to buy all sorts of software, but mostly games through an interface that also provides chat services and community forums. But the primary utility of this platform is that it’s a marketplace for buying and selling games, and it has match-making features for online multiplayer games, serves as a sort of library for gamers, so all their games are launchable from one place, and it serves ...

    Climate Risk

    This week we talk about floods, wildfires, and reinsurance companies.We also discuss the COP meetings, government capture, and air pollution.Recommended Book: If Anyone Builds It, Everyone Dies by Eliezer Yudkowsky and Nate Soares TranscriptThe urban area that contains India’s capital city, New Delhi, called the National Capital Territory of Delhi, has a population of around 34.7 million people. That makes it the most populous city in the country, and one of the most populous cities in the world.Despite the many leaps India has made over the past few decades, in terms of economic growth and overall quality of life for residents, New Delhi continues to have absolutely abysmal air quality—experts at India’s top research hospital have called New Delhi’s air “severe and life-threatening,” and the level of toxic pollutants in the air, from cars and factories and from the crop-waste burning conducted by nearby farmers, can reach 20-times the recommended level for safe breathing.In mid-November 2025, the problem became so bad that the government told half its workers to work from home, because of the dangers represented by the air, and in the hope that doing so would remove some of the cars on the road and, thus, some of the pollution being generated in the area.Trucks spraying mist, using what are called anti-smog guns, along busy roads and pedestrian centers help—the mist keeping some of the pollution from cars from billowing into the air and becoming part of the regional problem, rather than an ultra-localized one, and pushing the pollutants that would otherwise get into people’s lungs down to the ground—though the use of these mist-sprayers has been controversial, as there are accusations that they’re primarily deployed near air-quality monitoring stations, and that those in charge put them there to make it seem like the overall air-quality is lower than it is, manipulating the stats so that their failure to improve practical air-quality isn’t as evident.And in other regional news, just southeast across the Bay of Bengal, the Indonesian government, as of the day I’m recording this, is searching for the hundreds of people who are still missing following a period of unusually heavy rains. These rains have sparked floods and triggered mudslides that have blocked roads, damaged bridges, and forced the evacuation of entire villages. More than 300,000 people have been evacuated as of last weekend, and more rain is forecast for the coming days.The death toll of this round of heavy rainfall—the heaviest in the region in years—has already surpassed 440 people in Indonesia, with another 160 and 90 in Thailand and Vietnam, respectively, being reported by those countries’ governments, from the same weather system.In Thailand, more than two million people were displaced by flooding, and the government had to deploy military assets, including helicopters launched from an aircraft carrier, to help rescue people from the roofs of buildings across nine provinces.In neighboring Malaysia, tens of thousands of people were forced into shelters as the same storm system barreled through, and Sri Lanka was hit with a cyclone that left at least 193 dead and more than 200 missing, marking one of the country’s worst weather disasters in recent years.What I’d like to talk about today is the climatic moment we’re at, as weather patterns change and in many cases, amplify, and how these sorts of extreme disasters are also causing untold, less reported upon but perhaps even more vital, for future policy shifts, at least, economic impacts.—The UN Conference of the Parties, or COP meetings, are high-level climate change conferences that have typically been attended by representatives from most governments each year, and where these representatives angle for various climate-related rules and policies, while also bragging about individual nations’ climate-related accomplishments.In recent years, such policies have been less ambitious than in previous ones, in part because the initial surge of interest in preventing a 1.5 degrees C increase in average global temperatures is almost certainly no longer an option; climate models were somewhat accurate, but as with many things climate-related, seem to have actually been a little too optimistic—things got worse faster than anticipated, and now the general consensus is that we’ll continue to shoot past 1.5 degrees C over the baseline level semi-regularly, and within a few years or a decade, that’ll become our new normal.The ambition of the 2015 Paris Agreement is thus no longer an option. We don’t yet have a new, generally acceptable—by all those governments and their respective interests—rallying cry, and one of the world’s biggest emitters, the United States, is more or less absent at new climate-related meetings, except to periodically show up and lobby for lower renewables goals and an increase in subsidies for and policies that favor the ...

    Thorium Reactors

    This week we talk about radioactive waste, neutrons, and burn while breeding cycles.We also discuss dry casks, radioactive decay, and uranium.Recommended Book: Breakneck by Dan WangTranscriptRadioactive waste, often called nuclear waste, typically falls into one of three categories: low-level waste that contains a small amount of radioactivity that will last a very short time—this is stuff like clothes or tools or rags that have been contaminated—intermediate-level waste, which has been contaminated enough that it requires shielding, and high-level waste, which is very radioactive material that creates a bunch of heat because of all the radioactive decay, so it requires both shield and cooling.Some types of radioactive waste, particularly spent fuel of the kind used in nuclear power plants, can be reprocessed, which means separating it into other types of useful products, including another type of mixed nuclear fuel that can be used in lieu of uranium, though generally not economically unless uranium supplies are low. About a third of all spent nuclear fuel has already been reprocessed in some way.About 4% of even the recyclable stuff, though, doesn’t have that kind of second-life purpose, and that, combined with the medium- and long-lived waste that is quite dangerous to have just sitting around, has to be stored somehow, shielded and maybe cooled, and in some cases for a very long time: some especially long-lived fission products have half-lives that stretch into the hundreds of thousands or millions of years, which means they will be radioactive deep into the future, many times longer than humans have existed as a species.According to the International Atomic Energy Agency, something like 490,000 metric tons of radioactive spent fuel is currently being stored, on a temporary basis, at hundreds of specialized sites around the world. The majority of this radioactive waste is stored in pools of spent fuel water, cooled in that water somewhere near the nuclear reactors where the waste originated. Other waste has been relocated into what’re called dry casks, which are big, barrel-like containers made of several layers of steel, concrete, and other materials, which surround a canister that holds the waste, and the canister is itself surrounded by inert gas. These casks hold and cool waste using natural air convection, so they don’t require any kind of external power or water sources, while other solutions, including storage in water, sometimes does—and often the fuel is initially stored in pools, and is then moved to casks for longer-term storage.Most of the radioactive waste produced today comes in the form of spend fuel from nuclear reactors, which are typically small ceramic pellets made of low-enriched uranium oxide. These pellets are stacked on top of each other and encased in metal, and that creates what’s called a fuel rod.In the US, alone, about 2,000 metric tons of spent nuclear fuel is created each year, which is just shy of half an olympic sized swimming pool in terms of volume, and in many countries, the non-reuseable stuff is eventually buried, near the surface for the low- to intermediate-level waste, and deeper for high-level waste—deeper, in this context, meaning something like 200-1000 m, which is about 650-3300 feet, beneath the surface.The goal of such burying is to prevent potential leakage that might impact life on the surface, while also taking advantage of the inherent stability and cooler nature of underground spaces which are chosen for their isolation, natural barriers, and water impermeability, and which are also often reinforced with human-made supports and security, blocking everything off and protecting the surrounding area so nothing will access these spaces far into the future, and so that they won’t be broken open by future glaciation or other large-scale impacts, either.What I’d like to talk about today is another potential use and way of dealing with this type of waste, and why a recent, related development in China is being heralded as such a big deal.—An experimental nuclear reactor was built in the Gobi Desert by the Chinese Academy of Sciences Shanghai Institute of Applied Physics, and back in 2023 the group achieved its first criticality, got started up, basically, and it has been generating heat through nuclear fission ever since.What that means is that the nuclear reactor did what a nuclear reactor is supposed to do. Most such reactors exist to generate heat, which then creates steam and spins turbines, which generates electricity.What’s special about this reactor, though, is that it is a thorium molten salt reactor, which means it uses thorium instead of uranium as a fuel source, and the thorium is processed into uranium as part of the energy-making process, because thorium only contains trace amounts of fissile material, which isn’t enough to get a power-generating, nuclear chain reaction going.This reactor was able to successfully ...
