Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right. Ask the barista/bartender if you can't find us.

We meet and sketch each other in Berlin. This is just an art gym that we also exercise our social skills. Afterwards usually we go for lunch as a group. **How Does It Work?** This event is simple, we meet and sketch each other doing portraits. Most of the participants use pencils or watercolors. Main aim is to socialize while we draw. There will be plenty of time to talk and get to know each other. We have to mention that this event is suitable for all levels. Many have started to draw in our event actually. **Structure** A. Warmup Phase: We pose to each other for 1 minute. B. Main Phase: We pose to each other for 10 minutes. C. Showcase Phase: We show some of the drawings we did to each other. **Who We Are** Creative Sessions is an art events group located in Berlin. **Is it Free?** The event is free of charge. It is advisable to get a drink though. This is a cafe, we need to have at least half of the people on each table with a drink. They accept only cash and most hot drinks cost from 2.50 to 3.50. **How to help or donate?** The event is provided for free but many people help this be a regular thing. We also need people to volunteer and help for minor tasks like the serving of the drinks or cleaning up. Just send us a message.

​Artificial intelligence is evolving at an extraordinary pace and is already reshaping how we work, learn, create, and make decisions. Some see AI as a powerful tool that will enhance human potential and solve global problems. Others warn about risks: bias, automation, loss of control, and long-term societal impact. ​In this meeting, we will explore AI from both perspectives — techno-optimism and techno-pessimism. What can AI actually do today? How does it work under the hood? Where are its real strengths, and where are its limitations? And how should we think about its future development? ​We invite both professionals and non-professionals to join the discussion. Whether you work with AI, study it, are simply curious about it, or approach it from philosophy, psychology, sociology, or everyday experience — your perspective is welcome. ## **​Preparation & Suggested Materials** ​To help you prepare, we’ve put together a curated reading list that includes books, research papers, articles, interviews, and practical guides. The world of AI moves fast, so alongside well-known books you will also find recent articles and research projects. ​You don’t need to read everything. Choosing one book, article, or even a short explainer is enough to take part in the discussion. You’re also welcome to bring your own material, as long as it relates to artificial intelligence and its societal impact. ​The full list of suggested readings (with links) is available here: ​[https://docs.google.com/document/d/17PoZmqzxQ5EJsET292lTI193ms_MZNvgv5XAnbVmRBY/edit?usp=sharing](https://docs.google.com/document/d/1Hu_dLOgnzvrfgE3CZQVBz6CqyPIgAMWxYE24o4yx3fQ/edit?usp=sharing&utm_source=luma) ***​Popular-Science Books*** ​Accessible but substantial books that explain how AI works and how it affects society. For example: * ​*Co-Intelligence* by Ethan Mollick * ​*Hello World* by Hannah Fry * ​*Artificial Intelligence: A Guide for Thinking Humans* by Melanie Mitchell * ​*Homo Deus* by Yuval Noah Harari ​***Scientific & Popular Articles*** ​Shorter texts for those with limited preparation time. These include: * ​A brief history of AI (Haenlein & Kaplan) * ​“On the Dangers of Stochastic Parrots” (Bender et al.) * ​Stephen Wolfram’s explainer on how ChatGPT works * ​Andrew Ng’s “AI is the New Electricity” ​***Real-World Applications & Practical Guides*** ​Materials for those interested in applied AI: * ​KDnuggets blog (case studies and practical use) * ​*Deep Learning Illustrated* * ​Google’s Prompt Engineering Guide ***​Research Projects*** ​For a forward-looking perspective: * ​Epoch AI * ​AI 2027 scenario ## **Important Information** ​​We aim to create a safe, inclusive space for sharing ideas and learning from different perspectives. Respectful dialogue is encouraged, and participants are asked to follow our **[Code of Conduct](https://docs.google.com/document/d/1zhC3yhSvmAoO4wx5TlEmW-oyxs5FhCXN7MD0f0I_SAc/edit?tab=t.0&utm_source=luma)**. * ​​**Age 16+** * ​​The discussion will be held **in English.** * ​​**Registration is required** to attend the event. * ​​Participation is free. Donations are optional and help support our meetings.

Ditch the old book club, where everyone has to read the same book...this is better! It works like this: Bring your own book. Come chat, have some tea or coffee, get to know your neighbors. Then we quietly read together, side by side, for about one hour, each one reading their own book, and afterwards we talk with each other about what we are reading. The usual agenda: - Arrival and introduction (~20 minutes) - ⁠Silent reading (~1 hour) - ⁠Discussion (~30-40 minutes) - ⁠Join us for a bite at a local restaurant afterwards, if you like! You may read in any language, you may read any book. We are a group of international residents of Berlin from many different countries, of all ages, and we converse in English. We welcome you! No registration needed – the event is donation based. All funds support the Offenes Wohnzimmer.

Einladung zu einer Reise hin zum eigenen Körper: Wenn unser Geist Urlaub macht, taucht darunter ganz von allein Spiel, Spontaneität, Leichtigkeit auf. Aber wie kommen wir in eine solchen Zustand? Zeit, Sanftheit, Kommunikation. Mit ganz unterschiedlichen, leicht zugänglichen, Impulsen und Übungen aus Contact Improvisation, Tanz und Movement beginnen wir mehr und mehr nach innen zu horchen. Durch sowohl Stille als auch Bewegung kommen wir zur Ruhe, wecken erhöhte Präsenz und Verbundenheit. Experimentieren, Loslassen und Albernheit sind willkommen, wenn wir mit uns selbst, in Partnerarbeit und in der Gruppe in Bewegung kommunizieren. Der Workshop richtet sich an alle Neugierigen, die dieses Im-Moment-Sein schon immer mal ausprobieren wollten - oder bereits Erfahrungen haben. Wie ist es, wenn wir für eine Weile alles kalkulierende fallen lassen und uns einfach nur dem hingeben, was unser gemeinsamer Atem kreiert? Bitte komm' in gemütlicher Kleidung, in der du dich gut bewegen kannst, ohne große Knöpfe, Schnallen, Accessoires, ohne allzu vollen Magen :-) 🕛 Wann: Sonntag 19.04.26, 14-17 Uhr 📍Wo: Villa Offensiv, Hasselwerderstraße 38, 12439 Berlin Anmeldungslink: https://forms.office.com/e/NuZgqM3Cjz \-\-\-\-\-\-\- When our mind takes a break, playfulness, spontaneity, and lightness emerge naturally. But how do we reach such a state? Time, gentleness, communication. Through diverse, easily accessible impulses and exercises from Contact Improvisation, dance, and movement, we begin to listen more and more to our inner selves. Through both stillness and movement, we find peace, awaken heightened presence, and experience connection. Experimentation, letting go, and silliness are welcome as we communicate with ourselves, in pairs, and as a group through movement. This workshop is for all those curious to experience this state of being in the moment—or who already have some experience with it. What is it like when we let go of all calculation for a while and simply surrender to what our shared breath creates? Please come in comfortable clothing that allows you to move freely, without large buttons, buckles, or accessories, and don't eat too much :-) 🕛 When: Sunday, April 19, 2026, 2–5 pm 📍 Where: Villa Offensiv, Hasselwerderstraße 38, 12439 Berlin Registration link: https://forms.office.com/e/NuZgqM3Cjz

You can join whatever court you like and move between courts during the event. We self-organize, so once you finish a game, you can start a rematch, mix with another court, or take a break as you see fit. Upon arrival, join the warmup happening on one of the courts.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
