Are you still reviewing code written by AI?
I’m not anymore. Neither is Lauren Tan.
She used to work at Cursor and is now at SpaceX AI. A few days ago, she did an interview describing how she develops now:
For a lot of agent-written code, she no longer reviews it line by line. She even lets agents auto-merge PRs.
When she wakes up in the morning, there may already be twenty-plus PRs in main. Last month, she merged close to a thousand PRs.
Why is she willing to do that?
Most people’s workflow is still this:
Hand the requirement to an agent. The agent changes the code. Then you start the project and check it yourself. If the page looks wrong, you screenshot it and throw it back. If the program errors, you copy the logs over. If performance is bad, you open DevTools yourself.
It looks like the agent is doing the work, but you never actually leave the loop.
So two agents at once is still manageable. Five and you start falling behind. Once a dozen agents are working at the same time, the human becomes the slowest part of the system.
The first thing Lauren did was hand verification over to the agent as well.
She has the agent start the app itself, operate the UI itself, capture Performance traces and heap snapshots itself, or open the iOS Simulator.
