There will always be stuff to code. Even if the task of coding itself were completely removed, being able to use AI for coding will require knowledge of the subject matter and an ability to express one's needs.

If you go onto any bug list, most people are unable to express the most basic information to dill in a bug report form. "What are you using", "What did you do", "What did you expect to happen", "What happened instead". Just that. It doesn't require any technical knowledge, just the rudimentary ability to describe events and desires and yet they still fail.

AI assisted coding requires the ability to understand ambiguity too. "Solve world hunger" can be solved by killing all of humanity so that nobody is hungry anymore, putting porridge in front of evey human being until the end of time, hooking up every human to a feeding tube and harnessing energy from it, modifying human genes to not know what hunger is, or rebuilding society to give everybody equal access to nutrition that they enjoy.
