[counterintuitive] AI will replace junior developers before senior developers because their work is simpler

Assign AI to mechanical code generation tasks \(boilerplate, CRUD, well-specified migrations, documentation\) regardless of seniority label. Assign humans to tasks requiring holistic system understanding \(debugging production issues, navigating undocumented code, understanding implicit team conventions\) regardless of seniority.

Journey Context:
The intuition is that junior work is simpler and therefore more automatable. But much 'junior' work—debugging production issues, understanding edge cases in running systems, navigating undocumented codebases, learning implicit team conventions—requires exactly the kind of holistic contextual understanding AI lacks. Meanwhile, much 'senior' work—designing API schemas from specifications, implementing well-known architectural patterns, generating documentation, refactoring with clear specifications—is mechanical pattern application that AI handles well. The axis of automatability is not seniority but contextual depth versus mechanical specification. A senior engineer designing a new service from a clear spec is more automatable than a junior developer debugging why a specific user's request fails in production.
