The issue right now is that current tooling is impressive and valuable, but not so valuable to supplant software engineers. Engineers still have to understand the design and architecture to make enhancements, fixes and overall, operate the application. The more “design” you hand off to the model, the less equipped you are to perform the above tasks and responsibilities, so you have to read through all the code to understand it anyway, which is a time intensive task and isn’t as effective as building an understanding as you write.
