IMO the author buried the lede:<p>&gt; Finally, understand that logging is expensive. I’ve seen entire teams of absolutely brilliant engineers spend years building, managing, and evolving logging infrastructure. It’s a hard problem, made much harder by overburdening the pipelines with unnecessary load.<p>It&#x27;s ultimately a piece about engineering cost versus benefit. There&#x27;s a real cost associated with logging every event with identity, to create an audit trail. Maybe that&#x27;s necessary in your domain, for compliance reasons or otherwise. In which case it falls into the bucket of machine-read structured logging, and you design for it. But for lots of domains, it isn&#x27;t strictly necessary.
