The Silent Skill Drain: How AI Code Generation Erodes Developer Mastery

While AI tools accelerate task completion, they create a 'cognitive debt' by enabling developers to skip the learning required to build durable expertise. Research shows that passive AI usage—copying generated code without understanding—produces significantly worse comprehension than active engagement, revealing that the real risk isn't the tools themselves but the default behavior of using them to close tasks rather than deepen knowledge. Over years of this pattern, developers risk becoming tool-dependent rather than truly capable engineers.
