This is a very bad take. LLM's, appear to be at their limit. They're autocomplete and are only as good as their inputs. They can't be depended on for truth. They can't be trusted to even do ~math~.

LLM's work as a place to bounce things off of, but still require editorial work afterword, even when they are working their best.

LLM's take huge amounts of power, both to make run, keep running, and to correct their output.

In general LLM's don't significantly reduce labor, and they are still ~very costly~.

Even the most basic assembly line multiplies someones output. The best assembly lines remove almost all human labor. Even bad assembly lines are wholesale better than individual assembly.

As long as it's LLM, I don't believe it will ever be "useful". We need a different technology to make this sort of assistance useful.
