Eh, I think my decades of experience writing my own code was necessary for me to develop the skills to be able to precisely tell the AI what to build, but I don't think I need to (always) write new code to know how to know what I need.

Now, if the thing I am building requires a technology I am not familiar with, I will spend some time reading and writing some simple test code to learn how it works, but once I understand it I can then let the AI build from scratch.

Of course, this does rely on the fact that I have years of coding experience that came prior to AI, and I do wonder how new coders can do it without putting in the work to learn how to build working software without AI before using AI.
