He doesn't know what he'll find, but that's the beauty of being part of the swarm: Even if you don't know where you're going, you still get there.
When you're on a smoothly-running train, it doesn't feel like you're moving; instead, it feels like the world is falling behind you.
It's only when the ride gets bumpy that you fully realize the truth:
You're not waiting for a train that will take you somewhere you're supposed to be going.
We're in transit already.
