[counterintuitive] AI coding assistants accelerate junior developer skill development

Require junior developers to explain every AI-generated code block before committing; pair AI assistance with mandatory senior review; treat AI output as a learning prompt not a shortcut; verify understanding by asking juniors to modify AI code without AI assistance

Journey Context:
AI assistants create a competence illusion: junior developers produce code that looks correct and passes tests, but they lack the mental models to evaluate whether the code is actually correct or merely plausible. This is automation bias compounded by the Dunning-Kruger effect—the less you know, the less able you are to judge AI output quality. Research shows developers using AI assistants produce more code but introduce more security vulnerabilities, and critically, they're less likely to notice those bugs because the AI's confident presentation masks uncertainty. Senior engineers can evaluate AI output against deep mental models of system behavior; juniors accept it at face value. The long-term risk is developers who can prompt but cannot reason about code—productive in lines-of-code but unable to debug, refactor, or make architectural decisions independently.
