Flat-out, you _need_ to understand the code you're merging. If you don't, ownership then lands on whatever AI agent you're using. Ultimately, you can't fire the AI agent in the same way you can fire the person at the driver seat when shit hits the fan and they've consistently caused incidents that force people to work late hours to resolve it.

I agree with the sentiment but I would add more nuance; you have to pick what is important to understand and what you can delegate; not all code is mission-critical.

In any case at the end you're the owner/accountable so you need to justify your and your agent choices.
