This is true. But, it's also true of assigning tasks to junior developers. You'll get back something which is a bit like what you asked for, but not done exactly how you would have done it.

Both situations need an iterative process to fix and polish before the task is done.

The notable thing for me was, we crossed a line about six months ago where I'd need to spend less time polishing the LLM output than I used to have to spend working with junior developers. (Disclaimer: at my current place-of-work we don't have any junior developers, so I'm not comparing like-with-like on the same task, so may have some false memories there too.)

But I think this is why some developers have good experiences with LLM-based tools. They're not asking "can this replace me?" they're asking "can this replace those other people?"
