Exactly, 1000 PRs per week probably equates to around ~100 engineers worth of output.

Hard to do an exact ROI, but they're probably saving something like $20,000,000+ / year from not having to hire engineers to do this work.

They still need someone to review and hopefully QA every PR. I doubt it’s saving much time except maybe the initial debug pass of building human context of the problem. The real benefit here is the ability for the human swe to quickly context switch between problems and domains.

But again: the agent can only move as fast as we can review code.

And they're not the only company doing this.

Financial capital at scale will begin to run circles around labor capital.
