One Developer's Account of Being Stretched Across Three Roles as AI Replaced Teammates

A software developer recently shared how their employer consolidated frontend, backend, and QA responsibilities into a single role after AI tools were introduced to fill the gap left by departing teammates. The title and pay remained unchanged, while the scope expanded dramatically across disciplines the developer had little prior experience in. Although AI proved effective at handling syntax errors and generating boilerplate quickly, it failed to provide the contextual judgment needed to evaluate whether solutions were appropriate for a specific codebase. The developer shipped two tests in their first month that passed but tested nothing meaningful, only discovering the flaw after a colleague flagged it in code review. The key takeaway was that AI closes the syntax gap almost instantly but does nothing to replace the hard-won experience required to distinguish working code from genuinely correct code.
