A robot stops in a warehouse. The fleet has dashboards — good ones! Grafana panels, traces, metrics, logs shipped to some index that costs real money every month. The team did their observability homework. And what happens next? Somebody opens a terminal, SSHes into the robot, and starts grepping. I find this endlessly fascinating.
