Manu speaking bluntly on em-dashes (prompted by this post):

I’ll keep writing however I want, and if someone decides to stop reading what I write because they suspect it’s AI-generated because I use too many em dashes, or parentheses, or any other punctuation or word or whatever, well, good riddance. I’m not gonna miss you.

I’ll speak bluntly as well: the hand-wringing over whether or not to use punctuation because LLMs generate text with them is…just fucking stupid. Nobody fucking cares people and if they do they’re the ones that have the problem, not you. Just stop already. Write how you want to write.
