Burry is mass-publishing the accounting case for his put options on Nvidia and Palantir while the rest of the market is still debating whether the capex cycle has legs. The math he’s referencing is specific. The Big Four hyperscalers just guided $650-700 billion in combined 2026

Human predators/dark personalities have unusual responses to death. Their brains are different, in particular the prefrontal cortex & amygdala, so they do not experience emotions like grief. They are fascinated, in a sadistic way, about grief in others. Sometimes they get angry

Attention is a form of love. Think about what your child has to do to get your attention. If the only way they get real engagement from you is by being on their phone or playing video games, that's what they'll optimize for. They'll develop elaborate strategies to extract

I am quoting directly from theeconomyofmeaning.com/2026/02/27/why… This is what eveyone needs to understand, including students and parents. "If anything, this is one of the most robust findings in cognitive science. What feels fluent is often misleading. Understanding in the moment is not

🚨 BREAKING: Someone just rebuilt the entire AI assistant stack in Zig. It's called NullClaw. The binary is 678 KB. It uses ~1 MB of RAM. It boots in under 2 milliseconds. No runtime. No VM. No framework. No garbage collector. Just raw Zig. Here's why this is absurd: →

It feels ironic that stacking mac studios is the cheapest way to run frontier AI today. But it actually makes sense. Nothing else beats the memory unit economics of Apple Silicon. Memory and memory bandwidth (not FLOPS) is what matters for local inference. Everything runs at

One of the best predictors of how successful a child will be is the amount of time they spend reading Parents should start reading with their kids as early as possible, even before they understand the words. This should be a daily activity. This is the best way to build a love

BEAM is the correct virtual machine for agents, and Elixir and Gleam are the correct languages. The future is massively concurrent

Mises obliterated the entire socialist project in 1920 with one devastating insight: "Where there is no free market, there is no pricing mechanism; without a pricing mechanism, there is no economic calculation." The socialists spent the next century pretending this problem didn't

Many people, even self-described conservatives, think socialism would work if human nature were different. No. Socialism cannot work, even in a hypothetical society of selfless genius saints. Why not? Because socialism centralizes economic choices. How much lumber do we

In the first decades of computer programming, there were no engineering principles. We just threw code at the machines and kept what worked. It has taken us 80 years to build up a minimal set of engineering principles -- and few yet follow and understand them. AI vastly

Rob Henderson argumenta aquí que la caída de las tasas de natalidad en los países ricos no se debe principalmente a costos económicos, sino a presiones sociales y de estatus impulsadas por las élites culturales. El verdadero obstáculo para tener hijos hoy día es social, no

What Uncle Bob says is true; I've been here for 46 years of this and it startles me when I actually remember how primitive our technology was. Probably the biggest change between interactive programming at a terminal and AIs was version-control systems. I remember before we had

"limit your kid's screen time" is correct advice today, but people are confused about why it's correct, and that matters because the reason has an expiration date. the issue with ipad kids was never too much screen time in some vague moral sense, but that the software on the

wise words from the best systems engineer I've worked with: "two things that make code actually maintainable: 1. reduce the layers a reader has to trace 2. reduce the state a reader has to hold in their head" applies to every codebase. always.

Kubernetes is beautiful. Every Concept Has a Story, you just don't know it yet. In k8s, you run your app as a pod. It runs your container. Then it crashes, and nobody restarts it. It is just gone. So you use a Deployment. One pod dies and another comes back. You want 3 running,

What is "AI psychosis"? There's clearly something going on, but several things mixed up under the name. It probably is not "AIs directly causing mental health crises". The number to watch for that is schizophrenia related emergency room visits, and that hasn't gone up in 5
