Agent Substrate, with Tim Hockin and Brandon Royal

Tim Hockin is a long term software engineer with Google Cloud and I would argue one of the fathers of Kubernetes. Brandon Royal is a product manager on GKE and has been behind the launch of multiple OSS projects like the Ray Operator for k8s, Agent Sandbox and our topic for today - Agent Substrate.
