I’ve recently been accused of using ChatGPT because I wrote a message with formal language and bullet points.

I'm unapologetic about using em-dashes. They're in my toolbox, and I reach for them. I can and do manually type em-dashes manually in both Linux and Microsoft Windows using the key-codes.

Anyone who is basing their opinion of the provenance of a piece of writing on whether em-dashes are used, then that opinion is emminently discardable lemming-babble.
