Ultimately, the author (the engineer writing the PR) should always fully own the impact and consequences of their code. This has always been true, but it’s become even more critical with AI-assisted coding and more junior engineers who primarily test only for functional correctness.

Just like AI now helps nearly everyone write code, it makes sense for AI to handle an initial pass at reviewing code too. However, there’s significant value in human reviewers providing an outside perspective—both to build shared understanding of the codebase and to catch higher-level issues.

TLDR; AI should do the first pass on reviews, but another engineer should also review the code for context and collaboration. Ultimately, though, the author still fully owns every line that gets merged.
