Dark Dynamism: drones, dark factories and deurbanizationJakub Šimek

Startup villages are the next frontier on the road to network states. This book aims to serve as a practical guide to bootstrap a desired future that is both definite and optimistic, to quote Peter Thiel’s framework. Dark Dynamism is my second book, a kind of sequel to Bespoke Balajisms I published on Kindle in 2024. The first book was about 90 ideas of Balaji Srinivasan and 10 of my own concepts, I built on top of his thinking. In Dark Dynamism, I focus on my ideas I played with over the last 8 years, inspired by Balaji Srinivasan, Alexander Bard and many people from the Game B and IDW scenes.

Enterprise Integration Is Dead! Long Live AI-Driven Integration with Apache C...Markus Eisele

We keep hearing that “integration” is old news, with modern architectures and platforms promising frictionless connectivity. So, is enterprise integration really dead? Not exactly! In this session, we’ll talk about how AI-infused applications and tool-calling agents are redefining the concept of integration, especially when combined with the power of Apache Camel. We will discuss the the role of enterprise integration in an era where Large Language Models (LLMs) and agent-driven automation can interpret business needs, handle routing, and invoke Camel endpoints with minimal developer intervention. You will see how these AI-enabled systems help weave business data, applications, and services together giving us flexibility and freeing us from hardcoding boilerplate of integration flows. You’ll walk away with: An updated perspective on the future of “integration” in a world driven by AI, LLMs, and intelligent agents. Real-world examples of how tool-calling functionality can transform Camel routes into dynamic, adaptive workflows. Code examples how to merge AI capabilities with Apache Camel to deliver flexible, event-driven architectures at scale. Roadmap strategies for integrating LLM-powered agents into your enterprise, orchestrating services that previously demanded complex, rigid solutions. Join us to see why rumours of integration’s relevancy have been greatly exaggerated—and see first hand how Camel, powered by AI, is quietly reinventing how we connect the enterprise.
