Yes I like where Zed is going with this.

I find pair programming very productive with agentic coding.

Two people (plus one or more agents) have the full context of the plan, execution, written code, automated and manual testing. Both can help drive to the point where it feels safe to sign off on the change right then and there and merge it.

Compare that to traditional PR / code review, where so much of that context is lost. At best the coder needs to spend a lot more time rewriting up a great PR description to bring the reviewer up to speed. At worst the reviewer needs to read lots of AI slop PRs, docs, transcripts, and code to try to make sense of things.

Doing it together then merging the thread and moving on can be efficient.
