Why EVs Will Win: It's About Costs, Not Climate Some good news and reason for optimism: the energy transformation is underway and unstoppable, with PV and batteries as key enablers and massively falling costs for both technologies. (1/x)

This kind of behavior is NOT more prevalent in Europe vs the US, and I will die on this hill. There are good angels, and there are bad angels. In the US, and in Europe. There is a special place in hell for Americans who feel the need to punch down on Europe for likes on this platform. While all Tier 1 US funds are investing more and more in Europe. US investment in European tech is (21 bubble excluded) at an all time high, as well as is cultural patronizing / stereotyping of Europe just to feel better about themselves. You don‘t need that, the US is a fantastic place. As is Europe.

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.

Eine Technologie ist in 30 Jahren 99 % billiger geworden. Nicht Computerchips – Batterien. Das verändert gerade die Welt. Im Jahr 1995: 5000 Dollar pro Kilowattstunde. Heute: unter 50 Dollar. Und der Preis fällt immer weiter. Wenn die meisten Menschen „Batterie“ hören, denken sie an Knopfzellen in der Armbanduhr oder AA-Batterien im Spielzeug. Heute aber treiben Batterien Autos an, die 500 Kilometer weit fahren. Sie speichern den Strom ganzer Städte. Sie versorgen Fabriken über Nacht. Das hat mit den Spielzeugbatterien so viel zu tun wie Tischkicker mit einem WM-Finale. Warum ist das so wichtig? Weil Energie die Grundlage von allem ist, was wir tun (das hat die ganze Welt ja gerade wieder zu spüren bekommen, dank Donald Trump). Eine sehr billige Technologie, Energie zu speichern, verändert nicht irgendein Detail – sie verändert das ganze Spiel. Der Preisverfall folgt dabei einem Muster, das Ökonomen Wright’s Law nennen. Bei Batterien hält es seit über 30 Jahren, egal ob Krise, egal welche Chemien und Architekturen die Ingenieure einsetzen. Wir alle kennen diesen Preisverfall von Computerchips. Das ist der gleiche Mechanismus – nur verändert er diesmal nicht, wie gut du Bilder auf deinem Smartphone bearbeiten kannst, sondern unser ganzes Energiesystem. Mal konkret: Ein Netzspeicher sind Hunderte Schiffscontainer voller Batteriezellen, aufgestellt auf einer Fläche so groß wie ein paar Fußballfelder, angeschlossen ans Stromnetz. Mittags, wenn die Sonne mehr Strom liefert als gebraucht wird, laden sie sich auf. Abends, wenn alle kochen und Netflix schauen, geben sie ihn wieder ab. Das ist auch keine Theorie mehr. Das passiert schon längst. In Kalifornien lieferten solche Speicher Ende März 2026 einen Rekord von 12,3 Gigawatt – 43 Prozent der gesamten Stromnachfrage am Abend. So viel wie sechs Hoover Dams. In Texas deckten Batterien im Sommer 2025 über 10 Prozent der Spitzennachfrage – und zum ersten Mal seit Jahren musste der Netzbetreiber die Menschen nicht anflehen Strom zu sparen, um das Netz zu sichern. In der Lausitz baut LEAG den größten Batteriespeicher Europas – 1 Gigawatt, auf einem ehemaligen Braunkohle-Standort. Wo früher Kohle verstromt wurde, stabilisieren bald Batterien das Netz. Und auf Firmenebene? Ein deutsches Aluminiumwerk hat mit Batteriespeichern seine Stromrechnung drastisch gesenkt – indem es den Verbrauch in den teuersten Stunden des Tages kappt. Ersparnis: 4,4 Millionen Euro pro Jahr, amortisiert nach etwas über einem Jahr. BMW Leipzig betreibt seine Montagelinien nachts netzunabhängig, mit Solar und Speicher vom eigenen Gelände. Nicht weil die Politik es vorschreibt, sondern weil sich die Ökonomie gedreht hat. Die Batterie-Revolution hat längst begonnen. Erzähl deinen Kollegen davon.

BREAKING: President of the European Commission, Ursula von der Leyen introduces EU Inc. President of the @EU_Commission says: "With EU Inc. we are making it drastically easier to start and grow a business all across Europe" The @euinc_petition is designed to create a new EU-wide corporate entity, like a Delaware LCC in the United States, giving firms full access to the ​EU single market and avoiding the patchwork of 27 national corporate laws. European Commissioner ⁠Michael McGrath says: "We need to incentivise companies to stay in Europe and encourage those who once looked elsewhere to return" The movement was Co-Founded by @andreasklinger and spearheaded by a number of European technology advocates including @MarvinTBaumann.

Inside @google, we have a system for sending small bonuses to peers that helped us out. It's used often, and builds a culture of gratitude. We added an AI tool that scans your chats, emails, whatever and generates a report that shows who helped you the most lately. So handy.

Not a bad take, but it's clear that we can't just copy what works in China and expect it to work here or even better. We need to find our own approach and that's the responsibility of entrepreneurs, while it's the responsibility of politics to get out of the way and reduce barriers.

@DominiqueCAPaul Die Grafik berücksichtigt nicht, dass die Erwerbstätigenquote stark gestiegen ist über den Zeitraum. Mehr Teilzeit, arbeitende Mütter, Rentner. Ich höre keine Forderungen der 4-Tage Woche. Ich höre aber einen Kanzler, der uns Faultheit und Verantwortung vorwirft

Wer ist „die Politik“, wenn nicht wir selbst? Ich finde die Arbeitsmoral des Durchschnittsbürgers ist kaum mit dem Wunsch nach Wirtschaftswachstum vereinbar. Wir können nicht der Politik die alleinige Schuld geben, dass nichts passiert und gleichzeitig eine Viertagewoche einfordern.

I spent time in Shenzhen last year and when I saw Merz come back from China saying Germans need to work more I immediately knew what broke his brain because I lived the exact same cognitive shock my first week in Huaqiangbei I burned through 4 prototype iterations of a motor controller board for less than a thousand bucks total, back home a friend was working on something similar and spent over 12 thousand for a single revision that took almost two months to arrive when you live that contrast in your own hands with your own project something permanently shifts in how you see the world and it goes way deeper than speed & cost what Shenzhen actually built is a collective learning organism, imagine 20 PCB fabs 15 injection mold shops 30 component distributors and a hundred firmware freelancers all within a 2km radius, looks insanely redundant from the outside until you realize redundancy is actually information density in disguise I watched this firsthand with an injection mold supplier I was working with, this guy had seen a hundred founders iterate similar thermal designs over 6 months so he proactively modified his tooling before I even opened my mouth, he knew what I needed before I knew what I needed, the intelligence lives in the relationships between the nodes and it compounds daily the west thinks about manufacturing as a cost center you optimize by centralizing… China accidentally built a distributed neural network of manufacturing intelligence where knowledge diffuses horizontally across thousands of agents faster than any single western company can process internally so when Merz comes back and says we need to work a bit more I think he saw the problem but COMPLETELY misdiagnosed the solution, telling Germans to work harder is like telling a horse to gallop faster when the other side built a combustion engine the gap is ARCHITECTURAL it’s ecosystem density, you need a custom connector in Shenzhen you walk 200 meters, in Munich you send an email and wait 3 weeks it’s iteration speed, parallel search vs sequential optimization at the system level, it’s risk tolerance, Chinese founders ship something broken on Monday fix it Tuesday ship again Wednesday while European companies are still in the approval phase for the pilot program of the feasibility study… and Merz only saw the surface, what he missed is the tier 2 cities like Hefei Chengdu Wuhan replicating the Shenzhen model at scale right now BYD going from irrelevant to outselling every european automaker combined in roughly 5 years, Huawei building its own 7nm chip under maximum sanctions when every analyst said it was physically impossible & behind all of that a government that treats advanced manufacturing as an existential national priority while europe debates whether AI needs another ethics committee I think what we’re watching is the most asymmetric economic competition in modern history and most western leaders are still framing it as a productivity problem when it’s actually an ontological one Europe & America are optimizing variables that China stopped tracking years ago meanwhile China is compounding on dimensions the west has no framework to even measure Merz at least had the courage to name it out loud and I respect that genuinely but working a bit more inside a broken architecture just means you arrive at the wrong destination slightly faster
