Parentheses in headings is a telltale AI sign now? I feel like this has been a common way for normal humans to write for ages.
Normal humans do it very rarely, LLMs do it all the time.
I wish we had metrics for claims like this. I feel like it's been a very common thing to see in blog posts written by humans, not AIs, over the last two decades.
It's probably not long till approximately nobody can distinguish LLM and human text.
