​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.

**Labor: Past, Present, and Future – Work, Power, and Purpose** Labor is a defining force of human life. It shapes how we survive, how societies are organized, and how power and resources are distributed. Work can provide stability, dignity, and meaning—but it can also lead to inequality, exploitation, and exhaustion. More than just an individual experience, labor is a collective reality that reflects the structure of our world. At its foundation, labor is tied to survival. Like all living beings, humans must expend energy to sustain life. Our bodies and minds are wired for effort, cooperation, and problem-solving. Yet human labor goes far beyond biology—it is structured by economic systems, cultural values, and political decisions that determine who works, how, and for whose benefit. Across history, labor has continuously evolved—and so have the struggles surrounding it. Workers have organized to demand rights, protections, and fair wages, giving rise to unions, movements, and political parties. In many countries, labor movements shaped modern democracy, from the Social Democratic Party of Germany in Germany to the Labour Party in the UK, alongside similar movements across Europe and beyond. These efforts are remembered and celebrated globally on Labor Day. Labor is not only a human phenomenon. In the natural world, cooperation, division of roles, and collective effort are essential for survival—from insect colonies to social mammals. These systems offer a broader perspective on work as something deeply rooted in life itself, while also highlighting what makes human labor unique: its complexity, inequality, and capacity for change. In today’s world, labor is undergoing rapid transformation. Automation, digital platforms, and globalization are reshaping traditional employment. Stable careers are giving way to flexible—and sometimes precarious—forms of work. At the same time, the psychological experience of labor is becoming more visible: questions of burnout, motivation, identity, and purpose are central to how people relate to their work. Looking ahead, the future of labor may challenge long-held assumptions. Artificial intelligence and robotics could significantly reduce the need for human labor in many sectors, while increasing demand in others. This raises fundamental questions: What is the role of work in human life? How should wealth be distributed? And how do we define purpose in a world where labor is no longer central to survival? We will explore how labor has evolved through history—from early forms of work to modern economies—and how worker movements and political forces like the Social Democratic Party of Germany and the Labour Party shaped rights and social change. We’ll also reflect on labor as a biological, psychological, and social experience—how effort, motivation, and cooperation shape both humans and the natural world—and how work today is being transformed by technology, from gig economies to automation. Finally, we’ll look ahead to the future of labor, asking what happens if work changes fundamentally, and how we might rethink purpose, fairness, and the role of labor in our lives. Join us for a critical and engaging discussion on labor—not only as work, but as a force that shapes society, identity, and the future. Together, we’ll reflect on how labor defines our lives today and how it might be reimagined tomorrow. *** 📅 Event Details 🗓️ Date: Saturday, 18 April 2026 ⏰ Time: 14:30 📍 Location: Hardenbergstraße 10, 10623 Berlin 📱 WhatsApp: For prep materials and directions (Group Chat) [Group Chat](https://chat.whatsapp.com/Ba8ZAaH2Yuk6FGmD3LLO7H)

Nice! You are looking for real long time friendship! You might have already lived in Berlin or other big cities and experienced the "Anonymous" culture for a while. Meeting random people over and over and never see the same person again! In order to find "Real Long Term Friendship" in Berlin, do as follows: * You should not care how many people are joining this meetup. You RVSP. Even if only one person is joining. Because if everyone are waiting for everyone else to RVSP, nobody joins and nobody finds a new friend. * You do not care how many people of the opposite sex are joining. You are looking for friends. Finding the best romantic partner in the world, while avoiding not very attractive others, can be your other goal, for another time. Here we are looking for Friends. Real ones. * You are going to risk a very precious property of yours: Your time! Yes, there are thousands of opportunities in Berlin, there might be a rock concert for free, a birthday party you might miss, an important person might call you and invite you spontaneously, but you never find new friends until you decide to risk your time and meet people anyway. "I will check my calendar and get back to you" also does not work. Commit your time and spend it. Trust me, you won't go bankrupt ;-) * You are ready to use your phone as a real phone! You might have been using your phone as a tablet to visit Instagram and Facebook and watch movies. But if you want to find friends, you must know that people might take your phone number and give you theirs. That means they will Call you! And you have to pick up the phone and answer it. If you want to find new friends, you must be ready to do something really hard for the first time after years: Call people first, and if they called you: Answer your phone! * You are going to meet some people twice! That's the point of friendship. We already can experience random encounters with random people in random places one at a time. But that is not called friendship. If you want friends, you must be ready to meet the same person more than once. If you agree with above, RVSP and COME! You will meet other people who think the same way. P.S: Now that you've read all the way down to here, I suggest you [watch this animation](https://player.vimeo.com/video/547249272?h=22f3dd0f6f).
