Today at Google I/O 2023, it was announced that Interaction to Next Paint (INP) is no longer an experimental metric. It's been hugely helpful to have a simple set of three metrics – focused on loading, interactivity, and responsiveness – that everyone can understand and focus on. How does INP compare to FID?

“The three pillars of observability at the time were metrics, logs, and traces,” Wilson said.
