As an em dash appreciator—and there are dozens of us!—I have mixed feelings on ChatGPT embracing our little guy. My suspicion is that it's a quirk of their RLHF tuning where the em dash—which is definitely distinct from the en dash and hyphen—came to be associated with authoritative writing.

The style in the UK – for professional writing, at least – has generally been ‘word en-dash word’. My understanding was that ‘wordem-dashword’ was a US style thing and I don’t think I’ve ever seen it used in a UK publication. (I suspect few non ‘writers’ know the difference between an en-dash and a hyphen and some publications also seem to be relaxed about it.)

So it was no surprise to me that ChatGPT used em dashes (I assume a US bias to its training data) and I immediately told it to stop using them (along with Title Case titles). (Source: professional writer for 30 years.)
