Stop it, please. Em-dashes are perfectly fine. On a throwaway Reddit-post, no. I understand the signal. But on a corporate publication or some other piece of professional writing, absolutely. Humans do use em-dashes on those.

I'm much more interested in what the private model "tweet-rejector" could be used for...

My wife is a professional fiction writer and it's disheartening to see sudden accusations of the use of AI based solely on the usage of em-dashes.

Is it? I feel like that depends on whether you take a prescriptive or descriptive point of view.

Oh no. That's really too bad. Fingers crossed they'll beat the VC curse because it is so close to perfect as it is right now.
