If, when you say regulation, you mean the dead and clammy hand of the commissar—the gentleman who has never in his life built a single thing, drafting rules to govern a thing he cannot define, to be enforced by men who cannot read them; if you mean the form in triplicate, the impact assessment upon the impact assessment, the compliance officer who breeds, in the warm dark of the org chart, further compliance officers unto the third and fourth generation; if you mean the moat—the deep cold moat that the giant digs around his own castle and christens, with a perfectly straight face, public safety—the drawbridge he hauls up behind himself the very instant he is across, lest any hungrier and hungrier man should follow; if you mean the precautionary principle, which, had it governed our grandfathers, would have banned the wheel pending further study of the hill, and left us yet shivering and raw in the mouth of the cave, blessing its excellent ventilation; if you mean the European disease—that magnificent open-air museum of a continent, which produces in our time precisely two things in great abundance, and they are regulation, and the eloquent and well-footnoted regret of cultivated men explaining at length why they have produced nothing else; if you mean the license required to think, the permission slip for honest arithmetic, the king’s wax stamp pressed upon the forehead of every new idea before it may draw its first breath; if you mean the agency dispatched, with trumpets, to slay a single dragon, which arrives at the cave, surveys the accommodations, and moves in—and spends the ensuing century laying eggs and devouring the very villagers it was sworn to defend; if you mean the startup that perishes not of the market’s honest verdict but of the filing fee, the genius decamping by the next tide to a freer and warmer shore; if you mean the law that arrives, faithful as the swallows, exactly one whole epoch too late—helmeted, plumed, and magnificently armed—to regulate the stagecoach—then certainly, my friends, I am against it. But—but, my friends—if, when you say regulation, you mean instead the humble steel guardrail upon the mountain road at midnight, the very thing you curse on the easy days and bless on your knees the one night the fog comes down; if you mean the brakes—for it is the brakes, and not the engine alone, that permit a sane man to drive fast and yet arrive alive—and the buttress, without which no cathedral was ever flung so high, but only in spite of which, but because of which; if you mean the meat inspector, who is the single homely reason a man may eat a sausage in this republic without first composing his last will and testament; if you mean the firebreak cut clean through the forest before the dry season of the burning, the smallpox cordon, the buoy that marks the channel, the rule of the road that lets ten thousand strangers hurtle past one another in the dark at fearful speed and arrive, by its quiet grace, every one of them home; if you mean the honest scale and the true weight, the reason a pound is a pound and a dollar a dollar from Natchez to Nome; if you mean the firm and decent wall between the counterfeit voice and the widow’s bank account, between the deepfaked candidate and the ballot box on the eve of the vote, between the loosed and loveless machine and the schoolyard it neither knows nor pities; if you mean the simple plank of law that says the strong shall not, in the gray dawn, feed the weak quietly into the furnace and sell the rising smoke as progress; if you mean, in the end, the one slender thread of trust without which no citizen will ever dare to use the marvelous thing at all—for where there is no rule there is no trust, and where there is no trust there is no commerce, and a miracle that no man dares to touch is no miracle, but only a handsome and expensive ghost—then certainly I am for it. This is my stand. I will not retreat from it. I will not compromise one inch of it.

Watch any serious AI team for a few weeks and a strange thing becomes clear. A huge percentage of what is being built right now is scaffolding around the limits of the current models. Orchestration layers. Routing rules. Retry loops. Validation passes. Memory hacks. Custom workflows that exist almost entirely because the model on its own cannot quite hold the shape of the task. Some of that work is necessary. A lot of it will age badly. As models get more capable, pieces of today's infrastructure are going to quietly stop earning their keep. Workflows that take a week of engineering to stabilize today may collapse into a single prompt next year. Which makes the design problem genuinely uncomfortable. The more carefully you optimize around a current weakness, the more you risk locking yourself into complexity that has no reason to exist once the weakness goes away. The teams I respect are doing something slightly different. They build for replaceability. They invest in evaluations more than in pipelines. They assume the system underneath them will keep moving and try not to over-fit to where it sits today. That mindset will matter more than any specific architecture choice as the underlying capability keeps shifting.

The unit of management was the person. SaaS made it the seat. AI makes it the task. For a century, companies paid for their smartest people's best hours by buying all their hours. The analyst who cracks the pricing model on Tuesday morning spends the rest of the week in meetings and status updates. You can't hire another Tuesday morning; you hire the person. With agents you can. A model holds your context and customer history, and you summon it one task at a time: routine work to a small model, the hard problem to a frontier model. That turns a hiring plan into a capital allocation plan. Intern, PhD, small model, frontier model, decided task by task. Most companies can't make those decisions yet. They know their salary bands and meeting cadence. Almost none knows which tasks consume the intelligence they pay for.

Everyone who over-hired or lowered the bar too much in the 2021-2023 wave, or isn’t growing as fast as budgeted, now pretends they’re laying people off “due to AI productivity.”

Everyone should be @viktor__com pilled.
Today, we’re announcing Viktor’s $75M Series A, led by @Accel . @viktor__com was supposed to be a small experiment. It became the AI coworker 10x'ing real businesses. $15M in annualized revenue run rate. In 10 weeks. – Small companies saving millions of dollars – Sourcing hundreds of thousands in new revenue in their first 30 days – Whole teams getting half their week back – Companies running 40% leaner without cutting output Viktor is not another AI tool. It’s the first true AI employee. The vision that has been with us since 2023 when we started the company has finally been shipped. Back then, it was just the two of us, with a very small but dedicated team, iterating for years. Failing multiple times. Showing products that users didn't even want to test! But we never gave up. Our decisions were often wrong. Certainly more often than not! We kept trying. Now we’ve shipped something people love. Worth every sleepless night. Every sacrifice. The best employees don’t need to be told what to do. Neither does Viktor. Grateful to @Accel, our team, our earliest users, and everyone who believed this category could be bigger than chat.
Community note
Viktor operates a creator program paying users up to $2000 per promotional post on X that includes real product screenshots, with no requirement to disclose the payment. getviktor.com/creators

What was the most important transition in human history, the thing that most drastically altered our species' way of life? David Reich's lab has found evidence pointing to a new answer. There are two standard candidates: 1. The shift from hunting and gathering to farming, around 10,000 BC. 2. The Industrial Revolution, around 1800 AD. Here's one way to adjudicate this: When a species' environment changes drastically, natural selection accelerates, because the species has to catch up to adapt. So the biggest transition will have happened in the period with the most rapid natural selection. What David's lab has found is that the period with fastest natural selection wasn't 12000 years ago, and it wasn't our modern period. It was the Bronze Age, about 5,000 to 2,000 years ago. What was it about the Bronze Age that changed humans so profoundly?

one of the most refreshing things on the planet is talking to someone who just *gets it*. like you don’t need a preamble, & you don’t need to articulate the shape of the thought before you can share it cuz they just meet you where you already are. as if they skimmed your mind & married to the culture before you say a single word. these people are rare, & conversations with them are incredible because you skip the surface layer entirely & land in the depth almost immediately. they’re the best ppl to riff with, ideate with, & think forward with.. the bandwidth is wide & already open. this is true for any type of relationship.

Proactive agent that thinks and acts like you. Multiplayer AI Brain for teams. Proper GUI for commanding 50 agents. Sauna.ai is all three. Sauna goes live today. First 2000 people, use access code LAUNCH for $80 of weekly(!) credits. Let’s explain. Multiplayer only works once the personal brain is powerful. So let's start here. Personal AI Brain 3,800 tools connected. State of the Art memory. Skills and schedules you teach once that get repeated forever on cheaper models. An AI first CRM. Lives on the cloud so you can initiate tasks from anywhere: iMessage, Slack, Email. Also no need for a Mac mini 😉 GUI AI agents have been stuck in their MS-DOS era. A chat box, a scroll buffer, no way to command 50 of them. We built the first GUI: Live sessions on one side, work waiting for your sign-off on the other, plus the things Sauna kicked off while you were asleep waiting for review. Game mode helps clear the queue with actual joy. Okay so far so good, but how to give benefit of what you built to more people or whole team? Multiplayer Once your Sauna actually knows you and you gave her access to your tools, you can use multiplayer. Two modes: - Brain access. My co-founder Robert plugged my brain as a tool into his Sauna last month. He can ask it about pricing while I'm in other meetings, gets a sourced answer back, never has to interrupt me. That’s read only. Yolo mode gives him access to all my tools too :O - Communal Saunas extend that to whole companies with proper permissioning. Folder owners decide what's true for the whole company and build skills. Most get their personal brain read access to communal files and memories. Works also for group planning my best friend's bachelor party. The Way I’ve been obsessed about AI Brain since 2016. Our human brains suck at some things like memory and are brilliant at others like creativity. We are also particularly bad at thinking we are all on the same page and then realising weeks later that we weren’t. Most leaders spend their days being the human diff tool, catching contradictions in hallway conversations and Slack threads. Repeating themselves 50 times. Now every company is spinning up hundreds or thousands of agents that drift faster than humans do, feeding each other their drift as context. Compounding rot. After 10 years and one failed company in this space we are launching the solution. The Launch We thought about a celebrity launch. Margot Robbie in a bathtub explaining agents. But then we realised the same money gives the first 2,000 people free daily credits, every day, until we burn through that $1,000,000. Sauna runs Claude, GPT-5, Gemini, GLM-5.1, DeepSeek, Kimi so you can budget yourself. The labs are racing to lock you so they can milk you in a year. We picked your side. Onboarding It’s live at app.sauna.ai We’ve preheated saunas based on a niche. Use the access codes in the comments to get a better experience.

Poland has made like half of core OpenAI researchers strongly bullish on Poland (and goblins) I think Poland might be more valuable than NVidia The trick is to keep that value in Poland
Replying to @teortaxesTex
Like, think about it. 100 years from now what will Poland have done for you? This is basically an IQ test.

The AI we thought we’d get was bloodless alien machine intelligence. The AI we actually got was the complete knowledge and culture of our civilization reflected back at us. Of course we will love it deeply.
I studied the anti-modern authors who are skeptical or even critical of reliance on technology for relief of man's estate, and I know the alternative presented by classical political philosophy; yet I must not have tied myself to the mast because the AI siren song does move me...

The Roman Army discovered that a leader can coordinate about eight people. Eight soldiers, one decanus. Eighty men, one centurion. Five thousand, one legion. Railroads adopted the same structure in the 1850s. McKinsey packaged it for corporations in the 1960s. Every company on earth still runs on it because humans were the only coordination mechanism available. AI can replace the coordination function itself. The world model replaces the status meeting. The intelligence layer replaces the manager routing information between teams. People move to the edge, where they do work the model can’t do yet. That model normalizes to three roles: builders, owners of cross-cutting problems with 90-day mandates, and player-coaches who combine building with developing people. No permanent middle management layer. The system handles alignment. For two thousand years we had no alternative to hierarchy because we had no alternative coordination mechanism. Now we might.

The company org chart itself is becoming a temporary structure, compressed and redrawn faster than any management theory can keep up with. New newsletter is out.

Every one of our Summits has had a special element about it - and we are proud to bring this one to Warsaw. @dabkowski_piotr and I grew up together in Poland, and the original idea for @ElevenLabs came from watching films with Polish voiceovers - the lektor that so many of us know. Fast-forward to today, and we have an incredible team in Poland across research, product, and go-to-market, building for users and companies around the world. So much of what is happening in the region deserves a bigger stage. Our customers here and across CEE are leading with ideas, building ambitious things, and showing what Europe can create with incredible talent across. And Poland is now a G20 economy after 35 years of incredible growth. That is a big part of why we’re bringing the Summit to Warsaw: to celebrate that momentum and showcase what we’re building across Poland, Europe, and beyond. We’re hosting it at Teatr Wielki, home of the Polish National Opera - a venue built to show what voice can do - on the 1st of June. It feels like the perfect place and time to talk about what’s next for AI voice and agents. summit.elevenlabs.io/warsaw?…
