This conflates two things.

One is LLMs writing code. Not everything and not for everyone. But they are useful for most of the code being written. It is useful.

What it does not do (yet, if ever) is bridging the gap from "idea" to a working solution. This is precisely where all the low-code ideas of the past decades fell apart. Translating an idea in to formal rules is very, very hard.

Think of all of the "just add a button there"-type comments we've all suffered.
