Platform engineering is not a replacement for DevOps. It's what happens when DevOps works well enough that it creates a new problem.

Here's the sequence most teams miss.

DevOps solves the wall between dev and ops.

Developers own deployments. Everyone automates. Software ships faster. This works well up to 30-50 engineers. Every team manages their own infrastructure. It's messy but manageable.

Then scale kicks in. At 80-100 engineers, "everyone owns their infrastructure" means: 12 teams with 12 different CI/CD setups, 12 different Kubernetes patterns, 12 different approaches to secret management. A new engineer needs weeks to understand how deployments work. A security audit reveals inconsistency everywhere. Senior engineers spend 30% of their time answering other teams' infrastructure questions.

DevOps didn't fail. It created the conditions for a new problem.
