KubeCon demo scales agent swarm from 50 to 16 million actors in three days

At the Google booth at KubeCon NA 2026, a demo called "Agent Substrate" lets attendees scan a QR code to launch their own agent in a gVisor sandbox — no sign-in required. The swarm scaled day over day: 50 actors on day 1, 65,536 on day 2, and 16,777,216 on day 3, running on 4,096 physical worker pods with 64x oversubscription and gVisor runsc isolation.
The control plane shows worker pool execution, an attendee agent fleet matrix, and an "L7 Request Parking Lot" where requests wait at the gateway while their actor restores from a snapshot instead of being rejected. Open source at github.com/moficodes/agent-swarm.
