Without the space connecting thoughtsâlike this.
They seem uncommon in natural language but even when used surrounded by space? Gpt uses them all the time without spaces.

There are a couple of different ways to join clauses in written speech, depending on oneâs intent and grammatical necessity. This sentence and the previous, for example, use commas.
One can clarify a point with parenthesis (like this) or adjoin a clause with an emdashâlike this. Sometimes emdashes are usedâin pairsâwhere commas would have sufficed.
It is certainly the case that emdashes are rarer to encounter in conversational writing. It hadnât occurred to me that they might signal AI generated content.
Personally, I would estimate that I use emdashes about as frequently as parentheses or colons (â:â). But semicolons (â;â) I almost never use.
I appreciate that they are grammatically correct, I think its the frequency of occurence that is off with ai. At least thats my perception
