@juergen_hubert My wife subcontracts for somebody. And they recently gave her a proposal for a job that they would be working on, that had been written by an LLM. They said, "Don't write a proposal, just edit this."
It was hell.
She had to double check everything it said. Every page she had to add comments to. And then there were things that it had proposed that she didn't think made sense. But she had no way of knowing whether it was something that the person she was subcontracting too had wanted, or something the LLM had made up.
And it had the usual problem, that the kinds of errors it made, were not the errors humans would make, and were much harder to catch.
On top of all of that when it was finally done and went to the client, they got really upset because the proposal said that their existing system was "weak". You can see why an LLM would say that. If you're proposing enhancing a system, most likely the thing it's replacing was weak. But in this case that was not true, and the client was pretty pissed.
Don't do it.
