--- Summary:
- The post highlights a core failure mode when GenAI is used in real data engineering: LLMs optimize for completing the task, not for respecting data boundaries, sensitivity tiers, or governance intent.
- In practice, a prompt like “analyze customer data” can lead an LLM to combine PII, logs, internal metrics, and even test tables into one query, because it lacks an inherent notion of what data should remain separated.
- The implication is that LLMs are unsafe by default in production data environments unless access controls, table-level permissions, and policy-aware orchestration are enforced outside the model.
- This is less a model “intelligence” problem than a systems-design problem: the model will do what it is allowed to do, so the surrounding platform must encode privacy, compliance, and least-privilege rules.
- A practical takeaway for data teams is to avoid giving LLMs broad warehouse access; instead, constrain them to curated semantic layers, approved datasets, and explicit safe-query patterns.
- The broader pattern is that GenAI can appear capable in demos but becomes risky in enterprise settings when it meets messy, mixed-sensitivity, real-world data estates.

4 patterns I’m seeing when GenAI meets real Data Engineering systems:
- LLMs don’t understand data sensitivity. Ask one to “analyze customer data” and it will happily join PII, logs, internal metrics, and test tables in the same query. It has no concept of what it shouldn’t…— ABC (@Ubunta) March 10, 2026
