I think a lot of people have a biased idea of writing code. When you're a good programmer, you will be able to prompt a pretty good concept and navigate through any missteps.

When you have no fucking idea what you're talking about, you cannot fix those issues. Simply telling opus "its broken, fix it" wont help. Sure, eventually it comes with a solution, but you have no idea if it's good.

Its like renting a bunch of construction tools and building a house. Unless you know what's important, you have no idea if your house will fall down tomorrow. At the end of the day, companies will always need an expert to sit there and confirm the code is good.
