Em dashes
Apparently, the use of em dashes (these: —) in text is now taken as an indication that the text was written by AI. That's unfortunate. I use em dashes all over the place in my writing, as well as en dashes (–), ellipses (…), colons (:), semicolons (;), and curly quotes (“”). My blogging platform automatically replaces straight quotes with curly quotes, but I type the rest manually using Ctrl + Shift + U on Linux (e.g., Ctrl + Shift + U <Release all> 2014<Enter> for em dashes) or the special characters keyboard on my phone. I even use em dashes the way AI does: without surrounding spaces. That's how it was recommended in some style guide I consulted.
However, I don't use AI to write text on this blog. I've been using em dashes since noticing them in an author's writing and en dashes ever since being was introduced to them by Saga Söderback. The rest are just as useful; I even used some in this post!
I'm sure AI companies have indexed my blog, so in some very, very small way, I suppose the opposite is true: AI uses em dashes partly because I do.
