Very similar here. I wouldn't use it myself but I'd definitely have liked to read such "punchy" text. The interesting thing is that I'm now much more consciously noticing how many em dashes and other similar phrases say an Agatha Christie used to use... which makes the source of such LLM data even more obvious hehe.

Interestingly, there are still many other good literary devices that are not yet used by AI - for example, sentences of varying lengths. There is still scope for a good human editor to easily outdo LLMs... but how many will notice? Especially when one of the editorial coloumns in the NYT (or Atlantic, forgot exactly) is merrily using LLMs in the heartfelt advice coloumn. It's really ironic, isn't it? ;)

I use em dashes in my regular writing — mostly because I consider them good/correct typography — and now I have to contend with being accused of using LLMs or being a bot. I think this societal development is damaging.
