In 1948, a 32-year-old at Bell Labs published a paper nobody fully understood. Engineers found it too mathematical. Mathematicians found it too engineering-focused. One prominent mathematician reviewed it negatively. That paper - "A Mathematical Theory of Communication", became the founding document of the digital age. The man was Claude Shannon. Father of Information Theory. At 21, he wrote the most important master's thesis of the 20th century. Working at MIT on an early mechanical computer, Shannon noticed its relay switches had exactly two states - open or closed. He had just taken a philosophy course introducing Boolean algebra, which also operated on two values: true and false. Nobody had ever connected these two things. His 1937 thesis proved that Boolean algebra and electrical circuits are mathematically identical, and that any logical operation could be built from simple switches. Howard Gardner called it "possibly the most important, and also the most famous, master's thesis of the century." Every digital computer ever built traces back to this insight. At 29, he proved that perfect encryption exists. During WWII, Shannon worked on classified cryptography at Bell Labs. His work contributed to SIGSALY, the secure voice system used for confidential communications between Roosevelt and Churchill. In a classified 1945 memorandum, he mathematically proved the one-time pad provides perfect secrecy, unbreakable not just computationally, but provably, permanently, against an adversary with infinite power. When declassified in 1949, it transformed cryptography from an art into a science. It laid the foundations for DES, AES, and every modern encryption standard. At 32, he defined what information is. His 1948 paper introduced one equation: H = −Σ p(x) log p(x) Shannon entropy. The average uncertainty in a probability distribution. The minimum bits required to encode a message. Three things followed: > He defined the bit - the fundamental unit of all information. His colleague John Tukey coined the name. > He proved the channel capacity theorem, every communication channel has a maximum rate of reliable transmission. You can approach it. You can never exceed it. > He unified telegraph, telephone, and radio into a single mathematical framework for the first time. Robert Lucky of Bell Labs called it the greatest work "in the annals of technological thought." Where his equation lives in AI today: Cross-entropy loss - the function training every classifier and language model, is derived directly from H. Decision tree splits use information gain, which is H applied to data. Perplexity, the standard LLM evaluation metric, is an exponentiation of cross-entropy. Every time a neural network trains, Shannon's formula runs inside it. He also built the first AI learning device. In 1950, Shannon built Theseus, a mechanical mouse that navigated a maze through trial and error, learned the correct path, and repeated it perfectly. Mazin Gilbert of Bell Labs said: "Theseus inspired the whole field of AI." That same year he published the first paper on programming a computer to play chess. He co-organized the 1956 Dartmouth Workshop, the founding event of AI as a field. The man: He rode a unicycle through Bell Labs hallways while juggling. He built a flame-throwing trumpet, a rocket-powered Frisbee, and Styrofoam shoes to walk on the lake behind his house. He called his home Entropy House. When asked what motivated him: "I was motivated by curiosity. Never by the desire for financial gain. I just wondered how things were put together." In 1985, he appeared unexpectedly at a conference in Brighton. The crowd mobbed him for autographs. Persuaded to speak at the banquet, he talked briefly, then pulled three balls from his pockets and juggled instead. One engineer said: "It was as if Newton had showed up at a physics conference." He died in 2001 after a decade with Alzheimer's, the cruel irony of information slowly leaving the mind of the man who defined what information was. Claude, the AI model, is named after Claude Shannon, the mathematician who laid the foundation for the digital world we rely on today.

Grok 4.6 just took #1 on CursorBench. Not only the highest score. It did it at a fraction of the cost of the models sitting right behind it. That combination is the real signal. Top-tier results are one thing. Top-tier results that stay cheap enough to run for long agentic coding sessions are something else. I see this as the practical edge that matters for real work. Benchmarks are useful. Sustained performance at low cost is what actually gets used.
Grok 4.6 on extra high thinking mode now achieves #1 score on CursorBench!

It’s that easy to use Grok @Bot
I launched Grok Bot for 24 hours, gave it 3 jobs, and stopped treating AI like a chatbot. I had it scan live X + web data for emerging AI products, research what people were actually saying about them, filter the obvious engagement bait, compare sources and turn the strongest signals into a structured brief. At the same time, I could have separate research paths looking at competitors, code or market opportunities instead of forcing everything through one conversation. That’s the difference I underestimated. I don’t want to sit inside a chat writing another prompt every 5 minutes. I want to define the objective, give the agent access to the right tools and data, let it execute, then step back in when judgment or approval is actually needed. The old workflow was prompt → answer → copy → repeat. The workflow I’m moving toward is assign → execute → verify. Once AI stops waiting for your next message, it stops feeling like software you use and starts feeling like work you delegated.

Grok Bot can recreate any viral video from the link 🤯 How it works: I send @bot a link to an AI clip. It watches the video and writes a prompt to recreate it (with any changes I want). Then it uses @imagine to generate the new video! I tried it on the subway trend 👇

I’ll give you the big picture: America has been living under two constitutions since 1964. The Civil Rights Act began as a ban on segregation. Then Griggs made unequal group outcomes illegal, Bakke locked race preferences into college admissions under the diversity banner, and Title VII and the EEOC grew into a permanent legal apparatus that can override private contracts, hiring decisions, and free association whenever the numbers look uneven. Christopher Caldwell’s point in The Age of Entitlement is that one constitution protects individual liberty, while the other enforces group equality. So, at which group’s expense, specifically, has this “equality” been happening in schools, universities, corporations, and government?

The Bataclan attackers who murdered 130 people in Paris were already known threats, but the European authorities still let them operate freely. Abdelhamid Abaaoud, the ringleader, had a conviction in absentia and an international arrest warrant yet moved between Syria, Greece, and Western Europe for months without being stopped. Samy Amimour was under formal judicial supervision after trying to join jihadists in Yemen, slipped it, traveled to Syria, returned to France, and helped carry out the massacre. Two more attackers entered through the Greek island of Leros on fake Syrian passports, riding the same migrant routes used by hundreds of thousands of real asylum seekers. France’s own Fiche S terrorism watchlist flagged thousands of people as security risks, including several connected to the attackers, but the designation carried no legal force so they remained free. The parliamentary inquiry later confirmed every name was already known. What was missing was the will to act before the massacre began.
If Denmark’s leftists can close the border to protect their welfare state, why don’t American leftists? While Germany threw the gates open in 2015, Mette Frederiksen’s government went turned Denmark into one of Europe’s strictest countries on immigration. They forced toddlers from majority non-Western neighborhoods into mandatory Danish language and values daycare starting at age 1. They became the first EU country to process asylum claims outside Europe and started stripping residency permits from Syrians once they ruled Damascus safe enough to return. Asylum applications dropped from over 21,000 in 2015 to under 2,000. They decided mass immigration without integration would bankrupt the system Danish workers spent decades paying into, so they closed the door. I suspect American leftists have ulterior motives.

Second time trying Grok Bot and I'm still not over it. It took my whole growth engine and split into 4 of itself. One's on content, one's on scheduling, one's watching engagement, one pulls it all into reports at the end. There's a master orchestrator on top deciding who does what and when, and I genuinely didn't set that part up, it figured out the division of labor on its own. I haven't touched it since I hit go. It just moves through the queue and only comes to me when something actually needs a yes or no. I keep forgetting this is still just @grok. What @xAI and @elonmusk are building here plays more like a team that clocked in already knowing the job, not a bot waiting for instructions.
WILDEST PART OF MY WEEK: told @bot Grok Bot to watch how I file expense reports once. Just once. Next day it had already processed the backlog. Logged into the portal, matched receipts to line items, flagged two duplicates I would've missed. Without me touching it again. Didn't write a script. Didn't set up a workflow. It just learned it by watching. WOW! Now I've got three Bots running in one thread: one on expenses, one triaging support tickets, one drafting follow-ups. They hand off to each other and only surface when something actually needs my sign-off. Feels like managing a small team. @SpaceX buying @Cursor suddenly makes a lot more sense watching this thing work.

everyone is looking at grok bot like it is five new employees the more interesting part is that they are not five isolated employees they share one persistent cloud environment: the same browser sessions, terminal, filesystem and authenticated tools - while a chief of staff can route work between them without waiting for you to open the laptop that turns one login into infrastructure a research bot can collect leads, pass them to a writer, hand the result to a designer and let an ops bot update the workflow all inside the same running machine the upside is obvious: less copying, fewer handoffs and work that continues while you sleep the blast radius is just as obvious: - authenticate only the services the whole agent fleet is allowed to reach - give every bot a narrow role description, because that description becomes its place in the org chart - keep irreversible actions behind human approval: sending, publishing, spending and production changes - store skills, configuration and long-term state inside `/workspace`, because the rest of the VM may disappear during an update - treat shared sessions as shared authority, not as separate bot identities the same architecture that makes grok bot useful is what makes it dangerous to configure casually my take: the breakthrough is not that you can hire five AI workers it is that they can operate like one persistent company inside your real tools and your job changes from prompting every task to designing the permissions, boundaries and handoffs the full chief-of-staff setup, session handoff model, approval matrix and `/workspace` survival strategy are mapped out in the article ↓

What, precisely, are women protesting outside the Lindsay Clancy trial? What oppression are they opposing? Why are women posting videos of themselves on TikTok raging at the world about the stresses of motherhood? What, in short, is going on with American women? The answer: we trained several generations of women that they were victims of precisely the institutions that give them – and men! – meaning and happiness. Then we replaced those institutions with social media contagion and endless victimhood. piped.video/watch?v=zwPFtrS2…

The reason Rome fell was because they stopped making Romans
We think the collapse in birth rates is a modern problem. It is not. The most powerful man in the world once faced the exact same thing, and he was so alarmed he passed laws to force his people to have children. This was not a modern government: it was Rome 2000 years ago... The emperor was Augustus, and by his reign the Roman elite had grown wealthy, comfortable, and reluctant to marry or raise families. Men preferred bachelorhood and affairs to the burden of a wife and children. Augustus found it alarming enough to legislate. Around 18 BC and again in AD 9, he pushed through the Lex Julia and the Lex Papia Poppaea, a sweeping set of laws designed to engineer a baby boom by decree. The measures were direct: unmarried men and childless couples faced penalties on what they could inherit. Those who married and had children were rewarded with faster careers and public honors. Women who bore three or more children were granted a special legal freedom, the ius trium liberorum, the "right of three children," releasing them from male guardianship. The state was, quite literally, paying its citizens to reproduce and fining them when they did not. It didn't work... The laws were resented, evaded, and endlessly tinkered with, and Rome's elite went on having small families anyway. The historian Cassius Dio records Augustus standing before the childless men of Rome and shaming them to their faces: "You are committing murder in not begetting in the first place those who ought to be your descendants." A city, he warned them, is not its buildings but its people: "For it is human beings that constitute a city, not houses or porticos or market-places empty of men." Now look at the numbers today. For a population simply to hold steady, women need to average about 2.1 children each. South Korea recently hit 0.72, the lowest rate ever recorded for any country on earth, and even after a small rebound to 0.8 in 2025, it remains less than half of what a country needs to sustain itself. Italy and Japan sit near 1.2, China around 1.0, Spain near 1.1. The United States is about 1.6, the United Kingdom 1.5. According to the UN, more than half the world's countries are now below that line. History doesn't repeat itself, the saying goes, but it often rhymes, and this pattern is old and eerily familiar. A society climbs to the height of its wealth and comfort, and at that very peak its people stop having children, and no law, no incentive, no sum of money seems able to talk them back into it. Rome tried, with the full power of an empire behind it, and failed. At its height the city held more than a million people, a size no European city would reach again for 1700 years, until London in the 1800s. The Roman historian Livy, writing as the Republic gave way to the empire, said his was an age that "can endure neither its vices nor their cure." Two thousand years later, staring at the same problem and just as unable to solve it, we may be watching the beginning of the same story... A civilization does not always fall to an enemy at the gates. As the historian Arnold J. Toynbee once said: “Civilizations die from suicide, not by murder.”

Interesting
I am going to start to share the leaderboard at VulcanBench more regularly. VulcanBench is the only benchmark I know that benchmarks across effort levels, on an eval suite of 100% real engineering tasks. Getting ready to sunset eval suite 3 and eval suite 4 is almost ready to go. Here's the current leaderboard for Eval Suite 3, Grok 4.5 High is the highest scoring model still with Fable 5 Low, yes Low, right behind it. What I've been able to uncover with VulcanBench is that way too many people are running models at Max effort, thinking that buys them more accuracy, when really it just costs more and uses more tokens so takes more time. If you're still in the mode of, tell my agent to do something then go get coffee, you're probably still living in the past. You can move faster, with higher accuracy, the key is not thinking you need Max effort all the time.
