BREAKING: Amazon data centers used 2.5 billion gallons of water in 2025

Tyler Cowen on how AI will change our lives. Excellent.

this is just the most ridiculous AI application i've ever seen lol a Peter Thiel-backed startup that makes AI collars for cows is now worth $2 billion and the more I read about it the cooler it gets. here's how it works: every cow wears a solar-powered collar that talks to a network of radio towers and an app on the farmer's phone instead of building physical fences, the farmer draws the fence on a map in the app, and the collar keeps each cow inside that invisible line using GPS when a cow drifts toward the edge, the collar plays a sound to steer her, and a gentle vibration tells her which way to go. it's like how a car beeps as you back up toward a wall the cows learn the cues in a few days so now a rancher can move an entire herd to fresh grass by sliding the fence on a map, without driving out to open a single gate and that same collar is reading each cow's body the whole time. it takes five readings per second on every animal, so the AI can catch a cow that's sick, injured, ready to breed, or about to give birth before a person would ever notice walking the field so it's basically like WHOOP for cows too lol and they gave the AI behind it the perfect name: the Cowgorithm it's been trained on more than 7 billion hours of real cow behavior, which is why Halter calls the data its real asset and moat. they know what a normal cow looks like better than anyone, so they can flag the odd one out instantly it's already on more than 1M cattle across New Zealand, Australia, and a bunch of US states. California even used it on public land to graze cattle in patterns that clear dry brush and slow down wildfires costs about $5 to $8 per cow per month a job that used to mean barbed wire, gates, and driving the fields all day is now mostly 1 person on their phone

Hello, we are Jonathan and Abigail - unashamed pedants who want to bring this affliction to bear on all things public policy and practice. We believe that details matter, especially in public administration. This is why today we are founding quibble: a campaign to fix the small stuff. Think, for example, about the cookie banner that we click on every webpage. Each instance is not a big deal, so we just put up with it. But its cumulative impact adds up - on average we press it 5 times per day. The European Commission estimates that it costs EU citizens 343 million hours per year. And who is there to represent the impacts of seemingly minor issues like this in a systematic way? We want quibble to be the answer. In the case of the cookie banner, lots of advocacy has rightly focused on privacy, but has this meant that user experience has taken a backseat? We believe there are ways to improve user experience without compromising on privacy. We will share more about this soon. Consider another example. Did you know that in some government-run car parks you can be fined for a minor keying error, such as accidentally typing a zero instead of an “o”? Again, we will come to the detail of this quibble in the coming weeks, but for now just consider again the question: who? Who is there currently to systematically represent the interests of the parker who is given an unfair ticket? An inherent feature of consumer interests is that those who have them rarely have enough other things in common to make collective organisation and representation feasible. This is the gap that quibble seeks to fill. Now of course excellent consumer interest groups exist. But understandably quibbles might not be at the top of their lists. Our hope is that quibble will be complementary; picking up the bottom-of-the-list issues faced by various groups - the stuff they are almost too embarrassed to raise because they are too small. We are not embarrassed about detail. If you’ve ever had a splinter, you know small things can have a big impact. This is what quibble is committed to tackling, and our wider hope is that by doing so we will also incentivise policy makers to be even more careful about detail.

Two economists just published a mathematical proof that AI will destroy the economy. Not might. Not could. Will — if nothing changes. The paper is called "The AI Layoff Trap." Published March 2, 2026. Wharton School, University of Pennsylvania. Boston University. Peer reviewed. Mathematically modeled. The conclusion is one sentence. "At the limit, firms automate their way to boundless productivity and zero demand." An economy that produces everything. And sells it to nobody. Here is how you get there. A company fires 500 workers and replaces them with AI. A competitor fires 700 to keep up. Another fires 1,000. Every company is behaving rationally. Every company is following the incentives correctly. And every company is building a trap for itself. Because the workers who were fired were also customers. When they lose their jobs faster than the economy can absorb them, they stop spending. Consumer demand falls. Companies respond by cutting costs — which means automating more workers — which means less spending — which means more falling demand — which means more automation. The loop has no natural exit. The researchers tested every proposed solution. Universal basic income. Capital income taxes. Worker equity participation. Upskilling programs. Corporate coordination agreements. Every single one failed in the model. The only intervention that worked: a Pigouvian automation tax — a per-task levy charged every time a company replaces a human with AI, forcing them to price in the demand they are destroying before they pull the trigger. No government has implemented this. No major economy is seriously discussing it. Meanwhile the numbers are already tracking the curve. 100,000 tech workers laid off in 2025. 92,000 more in the first months of 2026. Jack Dorsey fired half of Block's workforce and said publicly: "Within the next year, the majority of companies will reach the same conclusion." Nobody is doing anything wrong. Companies are following their incentives perfectly. That is exactly the problem. Rational behavior. At scale. Simultaneously. With no mechanism to stop it. Two economists built the math. The math leads to one place. Source: Falk & Tsoukalas · Wharton School Boston University ·

Here’s a simple solution. If you don’t like the assessment of your house, you should be allowed to change that assessment to an arbitrarily lower number, provided that you’re required to sell to anyone who offers you say 30% above that number

Finnish scientists trucked in real forest dirt and grass and laid it over the gravel at four daycare yards. They let the kids dig around in it for a month. The blood tests came back with changes the researchers hadn’t expected to see so fast or so clear. The study ran at ten daycares in two Finnish cities with 75 kids aged three to five. Four of the yards got the forest treatment: about a tennis court worth of soil and grass laid over the gravel, plus planters and peat blocks the kids could dig and climb on. Three others stuck with their normal gravel yards. The last three were daycares where the kids were already visiting real forests every day. After one month, the variety of bacteria living on the kids’ skin shot up, and the kind that helps train the skin’s immune defenses jumped the most. Their gut bacteria started to look like the gut bacteria of the forest-visiting kids. Their blood showed more of the immune cells whose job is to keep the body from freaking out at harmless stuff like pollen and peanuts, and overall inflammation dropped. The kids on the plain gravel yards showed none of this. Childhood asthma in the US doubled between 1980 and 1995. Food allergies in kids jumped 50 percent between 1997 and 2011, then jumped another 50 percent between 2007 and 2021. And peanut allergies in one-year-olds tripled between 2001 and 2017. The Finnish researchers think one of the reasons is simple: kids today don’t get dirty enough. 37 percent of American preschoolers now spend an hour or less outside on a normal weekday. Their immune systems are getting trained in environments stripped of the bacteria humans have always lived around. Aki Sinkkonen, who led the study, put it in plain words: “It would be best if children could play in puddles and everyone could dig organic soil.” The Finnish government is now helping pay for daycares across the country to make the same changes.

"Hurt" is not an original by Johnny Cash. The song was written by Trent Reznor (Nine Inch Nails) in 1994 for the album The Downward Spiral. Rick Rubin had to insist several times on Cash recording his version, at first Johnny found the idea completely insane because the original version is industrial and noisy. At 71, already very ill, almost blind and with trembling hands, Cash completely transformed the band. The iconic video, directed by Mark Romanek, was filmed at the House of Cash (his own museum). June Carter Cash appears looking at him fondly, the video was shot in February 2003, a few months before she died (May) and Johnny himself (September). Trent Reznor was so moved that he declared, "This song is not mine anymore." It is considered one of the best covers of all time.

Clemson is $1.5B in debt. Syracuse is closing or pausing 93 programs, UNC-Chapel Hill plans to cut spending by $89M over 3 years. Duke recently let 600 employees go in a $350M budget cut. Indiana public colleges announced a plan to eliminate or merge 580 programs statewide.

The first major university that publicly commits to a total AI ban in its undergrad teaching (no AI in class, in creating syllabi or class prep, creating & completing assignments, or grading) and makes that part of its brand will see a major surge in applications & enrollment.
