It's just a tool. Use it well or use it badly - just the same as any. If you are generating slop using the tool, we'll then that is your own problem.

For me, the AI is essentially "faster hands" that can type what I am thinking way faster than I can do it. I tell it what I want, I give it the broad architecture and design patterns/types to use, and any specific test conditions, and let it write all of that usually by the time I have responded to a single email or chat message or two. Custom instructions etc build overtime to address model blind spots or my own personal taste so I don't have to repeat myself in every prompt for cross-cutting things.

Does it "one shot it"? Almost never - we go around the cycle a few times, treating it like pair programming a junior or intern by keeping a close eye on the broad direction and making sure it is acceptable - course-correcting where it matters, but cutting some slack where it doesn't. Sometimes I ask it why it picked a particular approach (that I wouldn't have necessarily) and it gives me a cogent explanation and we go with it, so I actually sometimes learn new things from it too which is great.

The other use case is just it's sheer capacity to research a codebase and hold everything in it's attention at once. It can comprehend unfamiliar code way faster and way more in-depth than I can. So if you are in an unfamiliar code base or a language or framework you are not that familiar with, it absolutely shines because it can just absorb all that info in seconds, and then you can just drill it with questions and what-abouts and how does it do this and what technique is used for that and that, what are the existing patterns and norms in this codebase when it comes to foo or bar? Etc etc

What I am not doing is deferring everything off to the AI unless it really doesn't matter (e.g. disposable one-off or prototype code). Same that I would not expect a junior or intern to make big architectural decisions when implementing something - you keep them on a fairly close leash and watch what they are up to.
