$PI just became a payment option for real-world robot services via Fabric Foundation's RoboPay network.

Seems minor on the surface, but this is the only type of integration that actually matters. Real utility happens when someone pays for a service they were already going to buy — not when projects announce vague "partnerships" with no actual transaction flow.

The test isn't hype or announcements. It's whether people use it to pay for something they'd purchase regardless of which token they use.
