Then they might not read it at all. I often zone out as soon as I expect I'm reading slop and that's the reason try to ensure my own writing isn't slop adjacent.
I'm also not sure there is an "AI bubble." Everyone I know is using it in every industry. Museum education, municipal health services, vehicle engineering, publishing, logistics, I'm seeing it everywhere.
As mentioned elsewhere I've seen non-tech people refer to them as "AI dashes."
> if a test for what a symbol ‘really means’
There was no suggestion of such a test. No symbol has an intrinsic meaning. The point GP was about considering how your output will be received.
That point was very obviously made within a specific cultural context, at the very least limited to the world of the Latin alphabet. I'm sure there are other LLM signifiers outside of that bubble.
