>Why would you adopt agent first coding?

Since most work on software projects is going to be done via coding, debugging, QA, etc AI agents you should prioritize finding ways to increase the velocity of these AI agents to maximize the velocity of the project.

>Are you that bad at it?

That is irrelevant.

>Is there anything you really have to get done regardless of quality right this second?

You are implying that AI agents have low quality work, but that is not the case. Being able to save time for an equivalent result is a good thing.

>Just write the code yourself, and stop training your replacement.

AI labs are the ones doing the training better AI.
