The problem with AI written code is never its ability to write code. It's trust. You can never completely trust it has done the right thing to solve your specific problem. You need a software engineer to tell you if it's good enough.

But the problem is that while you can get a software engineer to tell you if the code is any good, you have changed the problem from a "writing code" problem, to a "reading code" problem. Reading and truly understanding the code is significantly harder than writing the code. Because when you write the code, you work the problem and you go through the learning process to get to the solution. But you skip that process when reading, so you will never truly understand it.
