Svět AI se hýbe rychleji, než stíháme psát dokumentaci. Každý týden přijde nový „killer model“ a vývojáři přebíhají od jednoho toolu k druhému. Výsledkem často není vyšší produktivita, ale: * workflow se rozpadá při každé změně modelu * roste bezpečnostní a procesní riziko * know-how zůstává v jednotlivcích místo v týmu A právě tady vzniká prostor pro náskok. V Unnits jsme postavili CODAGa jako střechu nad vaší AI. Je mu jedno, jestli zrovna vede Claude, GPT-4 nebo Llama. Vy držíte proces, kontext a know-how. Modely jen dodávají výkon. **Proč dorazit na Evennt #31:** * **Jednotný mozek týmu:** Jak zajistit, aby junior i senior pracovali se stejným kontextem a know-how nezůstávalo jen v hlavách jednotlivců. * **Pitva orchestrátoru:** Dan Charousek ukáže, proč je vlastní kontext a orchestrace důležitější než model, který zrovna vyhrává benchmarky. * **Konec rozpadu workflow:** Jak měnit modely podle ceny, výkonu nebo use-casu bez přepisování procesů a dokumentace. * **Know-how jako majetek firmy:** Jak uchovat kontext, rozhodnutí a znalost vašeho prostředí mimo konkrétní model nebo tool. **🗓️ Kdy:** Úterý 2. 6. 2026 od 18:00 📍 **Kde:** Unnits - Drtinova 8, Praha 5 Evennt #31 není o naleštěných prezentacích. Je to o živém demu (které se možná rozbije), o otevřené debatě s Danem Charouskem a o hledání cesty, jak z AI udělat předvídatelný proces, který firmě přináší stabilitu, kontrolu a konkurenční výhodu.

You went on that retreat, read the book, committed to meditate daily. And here you are at 3 am, drunkenly staring down a Žižkov doner, wondering what went wrong. You are not alone! Come share your spiritual misadventures. Its a space where you can bring a poem, story, koan etc. Or just come and hang out. All paths and experiences are welcome. We are meeting at Stromovka Park, at the clearing near Fontana Stromovka (pin in the description). Bring something to sit on, pets are also welcome! We’ll start with an opening circle, short group meditation and then move into sharing and discussion. If you arrive late and we are already meditating please join us quietly so you don't disturb others.

I have been studying the question of "self" online with Prof. Ellie Anderson and so I thought a prompt on the "self" might be interesting. Full confession: I had Claude create this prompt and I like it, so here goes: Imagine a thought experiment that merges two classic puzzles: > You undergo a procedure, performed neuron by neuron, in which every biological component of your brain is replaced with a functionally identical synthetic substitute. At each step, your behavior, memories, and personality remain unchanged. When the last neuron is swapped, is the consciousness experiencing the world still you? And — more pressingly — was there ever a continuous "you" to begin with? ### Questions to Wrestle With * If consciousness is purely physical, does the *gradual* nature of the replacement matter, or is it equivalent to being destroyed and rebuilt? * Could there be a "self" without continuity of experience — even moment to moment, while you sleep? On a more practical level, consider the simpler case first: **hemispherectomy** patients — people who have had an entire cerebral hemisphere surgically removed — often retain a strong sense of personal identity and continuity. This suggests "you" are not rigidly tied to specific physical material. But does that vindicate the synthetic neuron case, or merely show that identity is more *flexible* than we thought — not that it can survive *complete* substrate replacement? I used Claude so I could get this out today and let everyone have some time to consider it. Hope to see you at the Oracle. Sorry about the location change two weeks ago. That's what I get for trusting local weather predictions!
