    This week we talk about Yoon, martial law, and impeachment.We also discuss the PPP, chaebol, and dictators.Recommended Book: Starter Villain by John ScalziTranscriptIn the wake of WWII, Korea—which was previously held by the recently-defeated Japanese Empire—was split into two countries, the north backed by the Soviet Union and the south backed by the United States and its allies.North Korea had a guerrilla fighter and staunch Soviet-style communism activist, Kim Il Sung, placed at the head of its new government, while South Korea was to be led by a longtime local politician named Syngman Rhee, who had run the country earlier, from 1919 until 1925, at which point he was impeached, and then again in 1947-1948, as head of the country’s post-war provisional government.Rhee was a hardcore Korean independence activist during a period when the Japanese were clamping down on their mainland holdings and doing away with anyone who caused trouble or sparked anti-colonial protests, so he spent some time in exile, in China, returned to the US, where he was educated, for a bit, and then the US military returned him to Korea to run that provisional government once the dust had settled and the Japanese had been ousted from the area.Rhee was an ideal representative in the region by American standards, in some ways, as he was vehemently anti-communist, even to the point of killing and supporting the killing of something like 100,000 communist sympathizers during an uprising on South Korea’s Jeju Island. He was president when North Korea invaded, sparking the Korean War, and then refused to sign the armistice that would have formally ended the conflict in 1953, because he believed the only solution to the conflict between these nations was a military one, and he held out hope that the South would someday conquer the North and unify Korea as a nation, once more.Rhee then won reelection in 1956, and changed the country’s constitution to allow him to remain in office, getting rid of the two-term limit—which was not a popular move, but it worked, and he was able to run uncontested in 1960, because his opponent died of cancer in the lead-up to the election—though his opposition protested the results, claiming a rigged voting process, and this led to a huge movement by students in the country, which became known as the April Revolution; students were shot by police while protesting during this period, and that ultimately led to Rhee stepping down that same year, 1960.So Rhee was a western-educated, christian conservative who was vehemently anti-communist, though also living in a part of the world in which an aggressive communist dictatorship recently invaded, and was threatening to do so again—so it could be argued his paranoia was more justified than in other parts of the world that had similar frenzied moments and governments during the cold war, though of course the violence against innocent citizens was impossible to justify even for him and his government; his authoritarian rule was brought to an end following that shooting of student protestors, and that left a power vacuum in the country, and South Korea saw 13 months of infighting and instability before a General named Park Chung Hee launched a coup that put him in charge.Park positioned himself as president, and he did pretty well in terms of economic growth and overall national development—at this point the South was way behind the North in pretty much every regard—but he was also an out-and-out dictator who ruled with an iron fist, and in 1972 he put an entirely new constitution into effect that allowed him to keep running for president every six years, in perpetuity, no term limits, and which gave the president, so himself, basically unlimited, unchecked powers.The presence of a seemingly pretty capable, newly empowered dictator helped South Korea’s economy, manufacturing base, and infrastructure develop at an even more rapid pace than before, though his nearly 18-year presidency was also defined by the oppression he was able to leverage against anyone who said anything he didn’t like, who challenged him in any way, and who spoke out of turn against the things he wanted to do, or the constitution that allowed him to do all those things.In 1979, he was assassinated, and there’s still a lot of speculation as to the why of the killing—the assassin was in Park’s orbit, and was seemingly doing okay as part of that all-powerful government entity—but alongside speculation that it might have been planned by the US, in order to keep South Korea from developing a nuclear weapon, that it might have been the result of political jealousy, and that if might have been just an impulsive act by someone who was done being pushed around by a bully, it’s also possible that the perpetrator was a democracy activist who wanted to get a successful and long-ruling dictator out of the way.Whatever the actual catalyst was, the outcome was more political ...

    Assad Overthrown
    2024/12/10
    This week we talk about coups, the Arab Spring, and Bashar al-Assad.We also discuss militias, Al Qaeda, and Iran.Recommended Book: The Algebraist by Iain M. BanksTranscriptIn the early 2010s, a series of uprisings against unpopular, authoritarian governments spread across the Middle East—a wave of action that became known as the Arab Spring.Tunisia was where it started, a man setting himself on fire in protest against the nation’s brazenly corrupt government and all that he’d suffered under that government, and the spreading of this final gesture on social media, which was burgeoning at the time, amplified by the still relatively newfound availability and popularity of smartphones, the mobile internet, and the common capacity to share images and videos of things as they happen to folks around the world via social media, led to a bunch of protests and riots and uprisings in Jordan, Egypt, Yemen, and Algeria, initially, before then spreading to other, mostly Arab majority, mostly authoritarian-led nations.The impact of this cascade of unrest in this region was immediately felt; within just two years, by early 2012, those ruling Tunisia, Egypt, Libya, and Yemen had been toppled, there were attempts to topple the Bahraini and Syrian governments, there were massive protests in Iraq, Jordan, Kuwait, Morocco, Oman, Algeria, and Sudan, and relatively minor protests, which were still meaningful because of the potential punishments for folks who rocked the boat in these countries, smaller protests erupted in Djibouti, Western Sahara, Saudi Arabia, Palestine, and Mauritania.Several rulers and their ruling parties committed to stepping down soon, or to not run for reelection—some of them actually stuck with that commitment, though others rode out this period of tumult and then quietly backtracked.Some nations saw long-lasting periods of unrest following this eruption; Jordan had trouble keeping a government in office for years, for instance, while Yemen overthrew its government in 2012 and 2015, and that spun-out into a civil war between the official government and the Iran-backed Houthis, which continues today, gumming up the Red Sea and significantly disrupting global shipping as a consequence.What I’d like to talk about today, though, is another seriously disruptive sequence of events that have shaped the region, and a lot of things globally, as well, since the first sparks of what became the Arab Spring—namely, the Syrian Civil war—and some movement we’ve seen in this conflict over the past week that could result in a dramatically new state of affairs across the region.—In 1963, inspired by their brethren’s successful coup in nearby Iraq, the military wing of the Arab nationalist Ba’ath party of Syria launched a coup against the country’s post-colonial democratic government, installing in its stead a totalitarian party-run government.One of the leaders of this coup, Hafez al-Assad, became the country’s president in 1971, which basically meant he was the all-powerful leader of a military dictatorship, and he used those powers to even further consolidate his influence over the mechanisms of state, which meant he also had the ability to name his own successor.He initially planned to install his brother as leader when he stepped down or died, but that brother attempted to overthrow him when he was ill in 1983 and 1984, so when he got better, he exiled said brother and chose his eldest son, Bassel al-Assad, instead.Bassel died in a car accident in 1994, though, so Hafez was left with his third choice, Bashar al-Assad, which wasn’t a popular choice, in part because it was considered not ideal for him to choose a family member, rather than someone else from the leading party, but also because Bashar had no political experience at the time, so this was straight-up nepotism: the only reason he was selected was that he was family.In mid-2000, Hafez died, and Bashar stepped into the role of president. The next few years were tumultuous for the new leader, who faced heightened calls for more transparency in the government, and a return to democracy, or some form of it at least, in Syria.This, added to Bashar’s lack of influence with his fellow party members, led to a wave of retirements and purgings amongst the government and military higher-ups—those veteran politicians and generals replaced by loyalists with less experience and credibility.He then made a series of economic decisions that were really good for the Assad family and their allies, but really bad for pretty much everyone else in the country, which made him and his government even less popular with much of the Syrian population, even amongst those who formerly supported his ascension and ambitions.All of this pushback from the people nudged Bashar al-Assad into implementing an increasingly stern police state, which pitted various ethnic and religious groups against each other in order to keep them from unifying against the ...

    2024/12/03
    This week we talk about emissions, carbon credits, and climate reparations.We also discuss Baku, COP meetings, and petrostates.Recommended Book: The Struggle for Taiwan by Sulmaan Wasif KhanTranscriptIn 2016, a group of 195 nations signed the Paris Agreement under the United Nations Framework Convention on Climate Change, usually just called the Paris Agreement, which was negotiated the previous year, and which, among other things, formalized the idea of attempting to keep the global average temperature from increasing by 1.5 C, which is about 2.7 F, above pre-industrial levels.The really bad stuff, climate-wise, was expected to happen at around 2 degrees C above that pre-industrial level, so the 1.5 degrees cutoff made sense as sort of a breakwater meant to protect humanity and the natural world from the most devastating consequences of human-amplified climate change.This has served decently well as a call-to-arms for renewable energy projects and other efforts meant to reduce greenhouse gas emissions, and many nations have actually made really solid strides in that direction since this agreement was formalized, dramatically truncating their emissions in a variety of ways, while also laying the groundwork for long-term reductions by installing a whole lot of solar and wind, reviving old and building new nuclear power facilities, reinforcing and expanding their grids, including adding all sorts of large-scale battery storage, and figuring out ways to reduce energy consumption, which has allowed for the shut-down of coal and oil plants.Shorter-term solutions, like replacing more polluting and emitting sources of energy, like coal, with gas, have also put a big dent in overall global emissions, especially for entities like the US and Europe; this isn’t ideal as a permanent measure, because there are still a lot of emissions associated with gas, especially its transport, because of leakage, and gas itself, in the atmosphere, has really significant greenhouse properties, but in the short-term this has proven to be one of the most impactful solutions for some nations and large corporations, and it’s increasingly being seen as a transitionary measure, even by those who oppose the use of any fossil fuels long-term.Things have been going decently well, then, even if progress is still far short of where it needs to be for most countries to meet their Paris Agreement commitments, and far slower than many people who are watching this space, and analyzing whether we’ll be able to avoid triggering those much-worse climate outcomes, would prefer.One issue we’re running into, now, is that those original commitments were a little fuzzy, as the phrase “preindustrial period” could mean many different periods, even if it’s commonly assumed to be something like 1850 to 1900, in the lead-up to humanity’s full-on exploitation of fossil fuels and the emergence of what we might call the modern era—society empowered by things like coal and oil and gas, alongside the full deployment of electrical grids.Throughout this period, though, from the mid-19th century to today, the climate has experienced huge swings year to year, and decade to decade. The evidence showing that we humans are throwing natural systems way off their equilibrium are very clear at this point, and it isn’t a question of whether we’re changing the climate—it’s more a question of how much, how quickly, and compared to what; what baseline are we actually using, because even during that commonly used 1850 to 1900 span of time, the climate fluctuated a fair bit, so it’s possible to pick and choose baseline numbers from a range of them depending on what sort of picture you want to paint.Research from the World Meteorological Organization in 2022 found that, as of that year, we were probably already something like 1.15 degrees C above preindustrial levels, but that it was hard to tell because La Niña, a weather phenomenon that arises periodically, alongside its opposite, El Niño, had been cooling things down and dampening the earth-warming impacts of human civilization for about three years.They estimated, taking La Niña’s impact into consideration, that the world would probably bypass that breakwater 1.5 degrees C milestone sometime in the next four years—though this bypassing might be temporary, as global temperatures would increase for a few years because of the emergence of El Niño.Adding to the complexity of this calculation is that aforementioned variability in the climate, region to region, and globally. The WMO estimated that through 2027, the world is likely to fluctuate between 1.1 and 1.8 degrees C above preindustrial levels—and that at that higher range, El Niño might tip things into the especially dangerous 2 degree C territory the Paris Agreement was supposed to help us avoid.By late-2024, it was becoming increasingly obvious that the world had stepped past the 1.5 degrees threshold into unfamiliar climactic ...

    This week we talk about Mastodon, Threads, and twttr.We also discuss social platform clones, user exoduses, and communication fractures.Recommended Book: Invisible Rulers by Renée DiRestaTranscriptIn 2006, a prototype of a software project called twttr, t-w-t-t-r, was developed by Jack Dorsey and Florian Weber, that name used because the full twitter.com domain, the word with all its vowels, was already owned and in use, and because the vowel-less version of the word only had five letters, which aligned with SMS short codes for the US, which were basically shorthand versions of telephone numbers that were used in lieu of such numbers by mobile network operators at the time.Going without vowels was also super trendy in Silicon Valley back then, due to the flourishing of online success stories like Flickr.Twitter, in that early incarnation, was meant to be a one-to-many SMS service, which means sending text messages from one phone to multiple phones, rather than one to one, which was the default.This early prototype was used internally at Odeo, which was an early-2000s web-based media directory, founded by some of the same people who eventually founded Twitter as a company, and random fun fact, Kevin Systrom who eventually cofounded Instagram, was an intern at Odeo one summer, back in 2005, before the company was sold in 2007.Twitter was spun out as its own company the same year Odeo was sold, and by 2009 it had become the hot new thing in the burgeoning world of the web—folks were sending tens of thousands of tweets, messages that were shared one-to-many, though online, on the web, instead of via SMS, by the end of 2007, and that was up to 50 million a day by early 2010.The whole concept of Twitter, then, from its name, which was initially predicated on SMS short codes, to its famous 140-character limit, was based on earlier technology, that of text messages, and that sort of limitation—which has in the years since been messed with a bit, the company slowly adding more capabilities, including the sharing of images and videos and other media types—but those limitations have in part helped define this platform from its peers, as while Facebook expanded and expanded and expanded to gobble up all of its general-purpose social networking competitors, Instagram dominated the photo-posting space, and YouTube has locked down the long-form video world for more than a decade, twitter held its own as a less-sprawling, less successful by most metrics, but arguably more influential network because it was a place that was optimized for concision and up-to-the-minute conversation, as opposed to every other possible thing it could be.This meant that while it didn’t have the same billion-plus user base, and it didn’t have the ever-growing ad-revenue that Meta’s platforms could claim, it was almost always the more culturally relevant network, its users sharing more up-to-date information, its communities generating more memes, which were then spread to other networks days or weeks later, and it became a hotbed of debate and exclusive information from journalists, politicians, and business owners.A lot changed when Tesla and SpaceX owner Elon Musk bought the network in October of 2022, changing the name to X in mid-2023, and pivoting the company dramatically in basically every way: removing a lot of those earlier limitations, cutting the number of employees by something like 80%, and losing a lot of advertisers because of his many ideological statements and political stances—including his backing of former president and now president-elect Donald Trump in the 2024 election.What I’d like to talk about today are the twitter clones that have popped up in recent years, and one in particular that, despite its still-small size and arguable underdog status, is being heralded as the possible successor of Twitter—in that original, influential and scrappy sense—and what makes this network, Bluesky, different from other would-be successors in this space.—The leadership at X, including owner Musk, recently promoted a new feature on the app that refocuses attention away from buttons like likes and shares in favor of views—a metric of engagement that some analysts have claimed is meant to conceal the fact that the network is seeing a lot less actual, human engagement, and because it feeds people posts it wants them to see, this change allows them to artificially inflate the seeming activity on these posts for advertising purposes: they can say, hey look how much attention these posts are getting, please buy some ads, and that allows them to charge a higher price than if they were using those more conventional engagement metrics, which are apparently collapsing.As a company, X has been hemorrhaging money since Musk took over, its ad revenue, which makes up the majority of its income, dropping by nearly half from 2022 to 2023, and it lost another 24% from the first half of 2023 to the first half of 2024.One ...

    AI Scaling Walls
    2024/11/19
    This week we talk about neural networks, AGI, and scaling laws.We also discuss training data, user acquisition, and energy consumption.Recommended Book: Through the Grapevine by Taylor N. Carlson TranscriptDepending on whose numbers you use, and which industries and types of investment those numbers include, the global AI industry—that is, the industry focused on producing and selling artificial intelligence-based tools—is valued at something like a fifth to a quarter of a trillion dollars, as of halfway through 2024, and is expected to grow to several times that over the next handful of years, that estimate ranging from two or three times, to upward of ten or twenty-times the current value—again, depending on what numbers you track and how you extrapolate outward from those numbers.That existing valuation, and that projected (or in some cases, hoped-for growth) is predicated in part on the explosive success of this industry, already.It went from around $10 billion in global annual revenue in 2018 to nearly $100 billion in global revenue in 2024, and the big players in this space—among them OpenAI, which kicked off the most recent AI-related race, the one focusing on large-language models, or LLMs, when it released its ChatGPT tool at the tail-end of 2022—have been attracting customers at a remarkable rate, OpenAI hitting a million users in just five days, and pulling in more than 100 million monthly users by early 2023; a rate of customer acquisition that broke all sorts of records.This industry’s compound annual growth rate is approaching 40%, and is expected to maintain a rate of something like 37% through 2030, which basically means it has a highly desirable rate of return on investment, especially compared to other potential investment targets.And the market itself, separate from the income derived from that market, is expected to grow astonishingly fast due to the wide variety of applications that’re being found for AI tools; that market expanded by something like 50% year over year for the past five years, and is anticipated to continue growing by about 25% for at least the next several years, as more entities incorporate these tools into their setups, and as more, and more powerful tools are developed.All of which paints a pretty flowery picture for AI-based tools, which justifies, in the minds of some analysts, at least, the high valuations many AI companies are receiving: just like many other types of tech companies, like social networks, crypto startups, and until recently at least, metaverse-oriented entities, AI companies are valued primarily based on their future potential outcomes, not what they’re doing today.So while many such companies are already showing impressive numbers, their numbers five and ten years from now could be even higher, perhaps ridiculously so, if some predictions about their utility and use come to fruition, and that’s a big part of why their valuations are so astronomical compared to their current performance metrics.The idea, then, is that basically every company on the planet, not to mention governments and militaries and other agencies and organizations will be able to amp-up their offerings, and deploy entirely new ones, saving all kinds of money while producing more of whatever it is they produce, by using these AI tools. And that could mean this becomes the industry to replace all other industries, or bare-minimum upon which all other industries become reliant; a bit like power companies, or increasingly, those that build and operate data centers.There’s a burgeoning counter-narrative to this narrative, though, that suggests we might soon run into a wall with all of this, and that, consequently, some of these expectations, and thus, these future-facing valuations, might not be as solid as many players in this space hope or expect.And that’s what I’d like to talk about today: AI scaling walls—what they are, and what they might mean for this industry, and all those other industries and entities that it touches.—In the world of artificial intelligence, artificial general intelligence, or AGI, is considered by many to be the ultimate end-goal of all the investment and application in and of these systems that we’re doing today.The specifics of what AGI means varies based on who you talk to, but the idea is that an artificial general intelligence would be “generally” smart and capable in the same, or in a similar way, to human beings: not just great at doing math and not just great at folding proteins, or folding clothes, but pretty solid at most things, and trainable to be decent, or better than decent at potentially everything.If you could develop such a model, that would allow you, in theory, to push humans out of the loop for just about every job: an AI bot could work the cash register at the grocery store, could drive all the taxis, and could do all of our astronomy research, to name just a few of the great many jobs these ...

    This week we talk about the Double Reduction Policy, gaokao, and Chegg.We also discuss GPTs, cheating, and disruption.Recommended Book: Autocracy, Inc by Anne ApplebaumTranscriptIn July of 2021, the Chinese government implemented a new education rule called the Double Reduction Policy.This Policy was meant, among other things, to reduce the stress students in the country felt related to their educational attainment, while also imposing sterner regulations on businesses operating in education and education-adjacent industries.Chinese students spend a lot of time studying—nearly 10 hours per day for kids ages 12-14—and the average weekly study time for students is tallied at 55 hours, which is substantially higher than in most other countries, and quite a lot higher than the international average of 45 hours per week.This fixation on education is partly cultural, but it’s also partly the result of China’s education system, which has long served to train children to take very high-stakes tests, those tests then determining what sorts of educational and, ultimately, employment futures they can expect. These tests are the pathway to a better life, essentially, so the kids face a whole lot of pressure from society and their families to do well, because if they don’t, they’ve sentenced themselves to low-paying jobs and concomitantly low-status lives; it’s a fairly brutal setup, looked at from elsewhere around the world, but it’s something that’s kind of taken for granted in modern China.On top of all that in-class schoolwork, there’s abundant homework, and that’s led to a thriving private tutoring industry. Families invest heavily in ensuring their kids have a leg-up over everyone else, and that often means paying people to prepare them for those tests, even beyond school hours and well into the weekend.Because of all this, kids in China suffer abnormally high levels of physical and mental health issues, many of them directly linked to stress, including a chronic lack of sleep, high levels of anxiety, rampant obesity and everything that comes with that, and high levels of suicide, as well; suicide is actually the most common cause of death amongst Chinese teenagers, and the majority of these suicides occur in the lead-up to the gaokao, or National College Entrance Exam, which is the biggest of big important exams that determine how teens will be economically and socially sorted basically for the rest of their lives.This recent Double Reduction Policy, then, was intended to help temper some of those negative, education-related consequences, reducing the volume of homework kids had to tackle each week, freeing up time for sleep and relaxation, while also putting a cap on the ability of private tutoring companies to influence parents into paying for a bunch of tutoring services; something they’d long done via finger-wagging marketing messages, shaming parents who failed to invest heavily in their child’s educational future, making them feel like they aren’t being good parents because they’re not spending enough on these offerings.This policy pursued these ends, first, by putting a cap on how much homework could be sent home with students, limiting it to 60 minutes for youngsters, and 90 minutes for middle schoolers.It also provided resources and rules for non-homework-related after-school services, did away with bad rankings due to poor test performance that might stigmatize students in the future, and killed off some of those fear-inducing, ever-so-important exams altogether.It also provided some new resources and frameworks for pilot programs that could help their school system evolve in the future, allowing them to try some new things, which could, in theory, then be disseminated to the nation’s larger network of schools if these experiments go well.And then on the tutoring front, they went nuclear on those private tutoring businesses that were shaming parents into paying large sums of money to train their children beyond school hours.The government instituted a new system of regulators for this industry, ceased offering new business licenses for tutoring companies, and forced all existing for-profit businesses in this space to become non-profits.This market was worth about $100 billion when this new policy came into effect, which is a simply staggering sum, but the government basically said you’re not businesses anymore, you can’t operate if you try to make a profit.This is just one of many industries the current Chinese leadership has clamped-down on over the past handful of years, often on cultural grounds, as was the case with limiting the amount of time children can play video games each day. But like that video game ban, which has apparently shown mixed results, the tutoring ban seems to have led to the creation of a flourishing black market for tutoring services, forcing these sorts of business dealings underground, and thus increasing the fee parents pay for them ...

    This week we talk about peat, pig iron, and sulphuric acid.We also discuss the Industrial Revolution, natural gas, and offshore wind turbines.Recommended Book: Deep Utopia by Nick BostromTranscriptThis episode is going live on election day here in the US; and this has been quite a remarkable election season for many reasons, among them that there’s been just a boggling amount of money spent on advertisements and events and other efforts to claim attention and mindshare, and in part because the vitriol and tribalism of the past several elections—an evolved, intensified version of those things—has almost completely dominated all those messages.And as someone who’s based in a swing-state, Wisconsin, I can tell you that it’s been a lot. It’s been a lot everywhere, as US elections also claim more than their fair-share of news reportage in other countries, but in the US, and in the relatively few states that are assumed to be the kingmakers in this election, it’s been just overwhelming for months, for basically a year, actually. So instead of doing anything on the election, or anything overtly political—there’ll no doubt be time for that in the coming weeks, once the dust has settled on all this—let’s talk about coal. And more specifically, British coal.Coal has been used throughout the British Isles for a long time, with early groups burning unrefined lumps of the substance to heat their homes, though generally only when their local, close-enough-to-the-surface-to-be-gathered source for the stuff was pure enough to beat-out other options, like peat and wood, which was seldom the case in most of these areas.It was also used to create lime from limestone, the lime used for construction purposes, to make mortar, and it was used for metal-shaping purposes by blacksmiths.Beyond that, though, it was generally avoided in favor of cleaner-burning options, as coal is often accompanied by sulphur and other such substances, which means when burned in its natural form, it absolutely reeks, and it can make anyone unlucky enough to be caught in the smoke it creates tear-up, because the resulting sulfurous gas would react with their eye-moisture to create sulphuric acid; not pleasant, and even though it was generally better than peat and wood in terms of the energy it contained, it was worse in basically every other way.Earlier groups of people had figured out the same: there were folks in China as early as 1000 BC, for instance, who used these rocks as fuel for copper smelting, and people in these same early-use areas, where coal veins were exploitable, were really leaning into the stuff by the 13th century AD, when Marco Polo visited and remarked that the locals were burning these weird black stones, which granted them wild luxuries, like being able to take “three hot baths a week.”Groups in Roman Britain were also surface mining, using, and trading coal at a fairly reasonable level by around 200 AD, though it was still primarily used to process things like grain, which needed to be dried, and to work with iron—as with those Chinese groups, coal has long been appreciated for its smelting capabilities, because of its high energy density compared to other options.In the British Isles, though, coal was largely imported to major cities by sea, until around the 13th century when the easily accessed deposits were used up, and shaft mining, which granted access to deeper deposits via at times long tunnels that had to be dug and reinforced, was developed and became common, including in areas that hadn’t previously had surface sources that could be exploited.In the 16th century, this and similar innovations led to a reliable enough supply of coal that folks living in the city of London were able to largely replace their wood- and peat-burning infrastructure with coal-burning versions of the same.It’s thought that this transition was partly the consequence of widespread deforestation that resulted from a population boom in the city—more lumber was needed to build more buildings, but they also required more burnable wood fuel—though some historians have argued that what actually pushed coal to the forefront, despite its many downsides compared to wood and peat, is the expansion of iron smelting and the increasing necessity of iron for Britain’s many wars during this period, alongside England’s burgeoning glass-making industry.Both of these manufacturing processes, making iron and glass, required just a silly amount of fuel—making just one ton of the lowest-grade cast iron, so-called pig iron, consumed something like 28 tons of seasoned wood, and glass was similarly wood-hungry.What’s more, that combination of city expansion and the King’s desire to massively build-out his Navy meant timber resources were continuously being strained anywhere industry popped up and flourished, so those industries would then expand to areas where wood was still cheap, over time making wood it more ...

    This week we talk about Joe Rogan, Call Her Daddy, and podcast monetization.We also discuss Kamala Harris, Donald Trump, and double-haters.Recommended Book: You Sexy Thing by Cat RamboTranscriptIn the world of US politics, double-haters are potential voters who really just don’t like the candidate from either major political party, and thus they decide whether and how to vote based on who they dislike least—or in some cases who they would like to hurt, the most.This isn’t a uniquely American concept, as voters in many global democracies face similar situations, but it seems to be an especially pressing issue in this year’s upcoming US Presidential election—and election day is a week away as of the day this episode goes live—because the race is just so, so close, according to most trusted polls.In that same context, swing states are states that could swing either way, theoretically at least, in terms of who their votes go to, and because these swing states contain enough electoral college votes to allow even the candidate who doesn’t win the popular vote to win the presidency, that makes them especially vital battlegrounds.So there’s a scramble going on right now, for both parties, to muster their existing bases, to shore-up some of the demographic groups they’re relying upon in this election, and to get their messaging in front of as many of those double-haters and other undecideds as possible so as to maybe, possibly swing this neck-and-neck race in their direction.Toward that end, we’ve seen simply staggering sums of money pulled in and spent by both major parties’ campaigns: it’s looking likely that this will be the most expensive election season in US history, with just under $16 billion in spending across federal races, alone—which is up from just over $15 billion in 2020, according to nonpartisan group Open Secrets; that actually means this election will probably end up being just a smidgeon cheaper than 2020’s election, if you adjust for inflation, rather than comparing in absolute dollar terms, but both of these races will have been several times as expensive as previous elections, weighing in at about double 2016’s cost, and triple what these races tended to cost previously, in the early 2000s.For perspective, too, US elections were already quite a lot more expensive than elections held in other wealthy countries.According to a rundown by the Wall Street Journal, Canada’s 2021 election only cost something like $69 million in inflated-adjusted dollars, and US elections tend to cost about 40-times more, per person—so this is a population-scaled figure—than elections in the UK and Germany.The cost of local elections in the US have been increasing, as well, in some cases substantially, and that’s part of why unpaid exposure and promotion is becoming increasingly valuable: it takes a lot of communications oomph to puncture the hubbub of commercial marketing messages in the US, and while pulling in a lot of money to buy ads and fund other promotional efforts is one way to do that, it’s also possible to approach the problem asymmetrically, going to people where they already are, basically, and getting some of that valuable face-time without having to spend a cent on it.And that’s what I’d like to talk about today—specifically, efforts by candidates to get on popular podcasts, and why this medium in particular seems to be the go-to for campaigns at a moment in which the electoral stakes are historically high.—Podcasts, by traditional definition, are audio files delivered using an old-school, open technology called RSS.In the years since they first emerged, beginning in the early days of the 2000s, the transmission mechanisms for these audio files have become a bit more sophisticated, despite being based on essentially the same technology. They’ve been joined, though, by utilities that allow folks to stream undownloaded audio content, to ping the servers where these audio files are stored more regularly, and to attach all kinds of interesting and useful metadata to these files, which add more context to them, while also providing the fundaments of basic micropayment schemes and the capacity to include video versions of an episode, alongside audio.That video component has been pushed forward in part by the success of content-makers on YouTube, where for a long while podcasters have promoted their audio shows with visualized snippets, behind-the-scenes videos, and other such add-on content. Over the past handful of years, though, it has also become a hotbed of original video podcast content, some podcasters even using YouTube as their native distribution client—and that, combined with Spotify’s decision to start offering video podcasting content alongside audio podcasting content, in part to compete with YouTube, has pushed video-podders to the forefront of many charts.Multi-person conversational and interview shows have maybe benefitted most from ...
