What Should Humans Design When AI Can Write Most of the Code? AI can now write code. Not perfectly. Not always safely. Not without review. But it can write a great deal of code. It can generate functions, create tests, call APIs, build UI components, handle common errors, and produce large amounts of implementation detail at a speed no human developer can match. This changes the meaning of programming. For a long time, much of a programmer's work was the act of implementation itself. We read requirements, understood the system, designed functions, wrote types, created tests, handled edge cases, debugged errors, and gradually transformed an abstract idea into working code. Of course, programming was never only typing. It always required design, judgment, and understanding. But still, a large amount of time was spent translating structure into code. Now AI is starting to take over a large part of that translation work. So the question is not simply: Can AI write code?…
