I feel the opposite way, that git branching and merging will become a bigger part of the job as more code is written by agents in parallel and then accepted by other agents or humans.
for example it’s not out of the question that we could end up with tooling that does truly continuous testing and integration, automatically finding known-good deployments among a continuously edited multiplayer codebase
we’d have to spend a lot more energy on specifications and acceptance testing, rather than review, but I think that’s inevitable - code review can’t keep up with how fast code gets written now
Codex already has a fantastic review mode, and gemini / claude are building tools around pr review that work no matter how that pr was produced, so I think this interface is going to get baked in to how agents work in the near term.
