Total fanasy. I am an enterprise developer and use multiple AI tools all the time. They are very helpful at a low level, meaning AI is great, not perfect, at providing blocks of code for specific tasks you describe coherently. Very often this provided code is based on outdated versions or from drawing on misdirection in some website.

What its often bad at is providing code beyond specific tasks, especially if it has to plug into a larger app which always have mountains of unspoken goals, appearance, flow, and nuance. This code is often wrong.
