> If LLMs get better at writing—which I think is extremely likely—will you switch positions and say that now using LLMs without disclosure is A-OK?

I would say it is certainly significantly more ok. There are two reasons reading AI-generated text sucks now:

1. It's usually low value and not trustworth - I could have just asked the AI myself.

2. The prose style is horrible to read.

If we eliminate the second reason then it's definitely an improvement. (Although on the other hand the terrible prose can be quite a helpful indication that you're wasting your time reading slop, so maybe we shouldn't complain about it!)
