I switched to semicolons... They look similar enough in use to string things together. I'm sure AI is coming for those too though, and that will be a grim day because those are my last stand.

There are times when an em dash can be used in place of a semicolon, but I don't think that's the usual LLM usage. Instead it's replacing a replacing a comma, colon, or period.

Unless you're talking about restructuring your sentences to allow for a semicolon; that's fine.

For example that semicolon could have been an em dash, but I don't think it's the type that LLMs over favor.
