ex-Apple engineer gave Grok 4.6 two jobs inside Cursor, went to sleep, and opened the results live the next morning: no babysitting, no checking every generation, just a model left running on real work for hours. • 00:42 - reveal the website Grok redesigned overnight • 23:21 - go from a voice prompt to a full software stack • 45:43 - inspect the generated code + architecture • 01:21:26 - Grok 4.6 vs Opus 5 • 01:46:31 - live PR + Cloud Agent workflow Most coding demos test an AI for 5 minutes. This tests the thing that matters for agents: can the model keep working when you stop watching it? SpaceXAI built Grok 4.6 specifically around longer-running agent tasks, coding and more ambitious visual work. The endgame isn’t prompting faster. It’s giving an agent a job at night and reviewing finished work in the morning. Worth watching before you choose which model runs your overnight agent loops.

Unless rectified quickly, most of the US, Europe, and Asia will go extinct This is a true existential risk

Suspect we will start to hear about a “Pareto optimal” balance of computationally efficient humans, cheaper open-source tokens and frontier tokens. Our internal AI spend @Atreidesmgmt will be roughly 100x higher in August 2026 vs. March 2026. Still roughly doubling every month. Note that is before Grok Bot moves to consumption pricing which will likely create a step function when it happens (at least for me). AI means that scale has become more important to investing imo. I think there will be a minimum token spend required to be competitive in most knowledge based industries. The “compute inequality” referenced by Sholto in our discussion.

people don’t realize this, but 2026 appears to be the first year in human history where humanity as a whole is below replacement fertility. this has never happened before. not during wars. not during pandemics. for the first time in human history, we are not producing enough children to replace ourselves. this is the only real existential crisis.

Did you know Elon Musk was weirdly "predicted" in a Wernher von Braun book nearly 80 years ago? In his 1948 novel *Project Mars*, von Braun describes a future Martian government led by a figure called the "Elon." It's not a person's name, but a title for the head of government. Still, considering Elon Musk's lifelong obsession with Mars, this has to be one of the strangest coincidences in space history!

Rome handed out free grain to 40,000 citizens in 73 BC. By 46 BC, Julius Caesar found 320,000 people lining up for their monthly ration. That eight-fold expansion happened in under three decades, and it shows you how welfare states actually grow. No Roman senator stood up and announced a plan to addict a third of the city to government bread. It happened incrementally, through political competition. Each magistrate who wanted votes expanded eligibility. Each expansion normalized the next one. The citizen who once considered the dole shameful eventually expected it, then demanded it, then organized politically to protect it. This is the core mechanism free market thinkers have identified across every era: once you create a transfer program, you create a constituency for that program. Recipients vote. Administrators build careers. Grain merchants who supply the state develop a stake in keeping the contracts flowing. The political economy locks in. Caesar, to his credit, actually cut the rolls back to 150,000 through verification audits. It was one of his more economically coherent moves, though the Senate still murdered him. His successors quietly let the numbers climb again. What did the dole require? Massive grain imports from Sicily, Sardinia, and Egypt, organized through state logistics at state expense, funded by taxation and conquest. When the conquest revenue dried up, the obligation remained. Rome had written a check against future military success, and future military success eventually failed to arrive. The lesson is not complicated. Distribute a benefit and you distribute dependency. Distribute dependency and you distribute political power to whoever controls the distribution. The grain dole didn't weaken Rome overnight, but it made every subsequent reform politically impossible.

Three months later, Grok’s progress is amazing, and @bot makes it even more powerful and easier to use. This is the fidelity using the same prompt: “Explain Navier-Stokes equation and how it relates to airfoil design with actual fluid dynamics simulation.”

Just stop doing this dumb shit. If some made-up rule says you have to, just break or change it.

One of the most eloquent explanations of immigration you’ll ever hear. Milton Friedman had an extraordinary ability to cut through the political bullshit and explain complicated issues with simple economic logic. Still relevant today. 🎯

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.”

🚨 UPDATE: The Karmelo Anthony legal team is IN SHAMBLES after bombshell texts came out that he fantasized about m*rder before killing Austin Metcalf "How many bullets u want coming out of ur chest?" "When I st*b somebody I'm gonna lick their blood off the blade" 2 hours before: "I'm lowkey on the verge" 🤯 UTTER MADNESS He needed the death penalty!

Grok Voice Think Fast 2.0 just ranked #1 on Artificial Analysis’ new Speech Agent Arena for highest Task Success Rate This benchmark actually measures what matters Real people talk to hidden voice agents across practical scenarios. Task Success Rate tracks whether the AI understands the request, calls the correct tools, and successfully completes the job It’s not just about sounding natural. It’s about whether the voice agent can actually get things done Grok finished #1

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.

Elon Musk: "Asylum was supposed to mean that if you go back to your country, you'll get k*lled." "Asylum seekers [now] go on vacation to the country that they're seeking asylum from… That doesn't make any sense."

Bloody hell. I’ve been grossly misinformed about Bolshevism.

Elon Musk sent every Tesla employee a memo that took authority away from their managers and handed it to them. He never asks for more hours. Every rule moves a decision closer to the person doing the work. Musk: “Excessive meetings are the blight of big companies and almost always get worse over time.” Companies have a role for everyone who creates process and no role for anyone who removes it. Meetings and approval chains survive because removing them was never anyone’s job. Musk: “Walk out of a meeting or drop off a call as soon as it is obvious you aren’t adding value.” Attendance has always been treated as proof of commitment. He made it worthless, and contribution became the only thing that counts in the room. Musk: “It is not rude to leave, it is rude to make someone stay and waste their time.” Ordinary manners protect whoever called the meeting. He moved that protection to everyone else sitting quietly with real work waiting on them. Musk: “Don’t use acronyms or nonsense words for objects, software, or processes at Tesla. Anything that requires an explanation inhibits communication.” Internal vocabulary converts knowledge into status and charges every newcomer a fee to participate. A company that speaks plainly can absorb talent at full speed. Musk: “Communication should travel via the shortest path necessary to get the job done, not through the chain of command.” Most good ideas die in transit, three levels below anyone with the power to act on them. Musk: “Any manager who attempts to enforce chain of command communication will soon find themselves working elsewhere.” The only threat in the entire memo. A manager who insists on being routed through is buying his own relevance with everyone else’s time. Musk put a price on it. Musk: “Always pick common sense as your guide. If following a company rule is obviously ridiculous in a particular situation, the rule should change.” Following a bad rule normally shields you. Exercising judgment exposes you. He flipped which one carries the risk, and every rule now has to earn its place against the person applying it. Every institution drifts toward protecting its own comfort. The ones that keep building are held together by people who rewrite the rules back down to something a single person can act on. Nothing on that list requires a budget, a headcount, or a title. You can run the entire memo from wherever you are sitting right now. Most people never test it and never learn it was permitted the whole time.
