The next generation of agents won't just answer questions. They'll work autonomously, collaborate with other agents, and learn from experience. As we move from interactive chatbots to persistent agent workforces, the infrastructure powering them needs to fundamentally evolve. In this talk, we'll explore the emerging architecture of agentic systems, from stateful sandboxes and persistent memory to agent communication and orchestration. We'll examine why today's agent platforms aren't built for this future, and what it will take to power a world where teams of agents can tackle complex, long-running work together.
