The rise of AI tools such as GitHub Copilot and ChatGPT has reshaped software development by providing substantial support for coding and debugging tasks. Although these tools enhance productivity and reduce routine workload, existing research has largely emphasized short-term efficiency gains, leaving their long-term cognitive and pedagogical effects insufficiently explored. This study investigates the cognitive trade-offs associated with sustained reliance on generative AI, with particular attention to students and junior developers. Recent empirical findings indicate that excessive dependence on AI assistance may weaken deep debugging skills, impede conceptual understanding, and challenge... More >
