  "account": "Anyone who's ever been on call knows the feeling of dashboards flashing red and the race to find the root cause. Solving the problem feels like a constant effort, while figuring out what the problem really is takes more time. When vendors promise AI can solve that, it's tempting to believe, though the reality is more nuanced.\n\nFinding symptoms is easy – isolating the cause is not. Many \"AI-driven root cause analysis\" tools are great at showing that several alerts belong to the same issue, but they struggle to explain what that underlying issue is. Correlation, alert grouping and noise reduction are useful, yet they don't equal causal diagnosis. The distinction between correlation and diagnosis is crucial. Understanding why alerts fire is far more valuable than just recognizing they're related.\n\nCreating a system that can truly diagnose causes requires moving beyond simple alert correlation. It needs to analyze the relationships between components and determine how changes in one part produce effects elsewhere. That's a different process than just stacking up more dashboards. A real causal diagnosis process would involve:\n\n1. Correlating events\n2. Building a model of how changes in upstream services affect downstream symptoms\n3. Testing the direction of cause-and-effect relationships\n4. Verifying the model against past incident history\n5. Expressing confidence levels in its diagnosis conclusions\n\nBut most tools today stop at correlation, leaving the hard work of understanding causes undone. Sketched out, the process requires causal inference, incident history analysis, and calibrated uncertainty handling. This is a tall order – especially as we layer in AI components that may behave unpredictably. Traditional deterministic systems are one thing, but non-deterministic AI models introduce a whole new set of challenges.\n\nThe biggest worry is that an AI system will confidently give wrong answers, especially when dealing with complex, AI-powered components. It risks eroding the trust engineers need when working under pressure. Once trust in an automated system is lost, it's very hard to rebuild. That's why treating postmortems seriously is so important. Detailed, causally clear postmortems generate the kind of training data that makes automated diagnosis smarter. Leadership plays a key role here – when a team invests in thorough postmortems, it's building the foundations for better AI-assisted incident response in the future.",
