A real product decision: artifacts and the review bottleneck
Show the "three eras" framing and why it changes which bets have the most value.
Step 1 of 3
The theses round can collapse into a prioritization matrix recited from memory. The antidote is one real decision narrative: a shift the product actually made, the bottleneck it relieved and the adoption signal that followed. This is that story.
Cursor's own framing is three eras of coding, each defined by where the developer's attention goes. Era one was Tab, attention on keystrokes. Era two was synchronous agents you steered, attention on the steering. Era three is async agents running in the cloud, attention on reviewing. The product question that era forces is sharp: if the human no longer watches the output stream, what do you ship them instead?
