A coding agent can inspect a repository, edit several files, run tests, and open a pull request. That is a meaningful expansion beyond autocomplete. It is not, however, the same as taking responsibility for software in production. The distinction matters because code generation is only one part of turning an ambiguous need into a dependable system change.
Code generation is not the whole engineering job
Software engineering begins before a function is written and continues after it is merged. Someone must perform problem framing, identify affected users, uncover constraints, choose tradeoffs, and define acceptance criteria. Someone must also decide whether test results are persuasive, whether a migration is reversible, and whether the organization can operate the change safely.
Compressible work includes boilerplate, mechanical migrations, repository searches, and routine test generation. Architecture is harder to delegate because system context and accountability shape its tradeoffs. Incident response is harder because operational context and accountability remain with the team. Security-sensitive work is harder because context and accountability determine acceptable risk. These areas are not intrinsically safe from automation; broader execution simply makes human judgment more consequential.
