The Emdash
Something I have noticed recently is people complaining they can no longer use the emdash because it is associated with AI. That is not the case! Continue to use it, just use it right.
Some emdash rules—the emdash indicates a new direction in thought, functioning similarly to a semi-colon; but where the semi-colon joins two thoughts together, the emdash indicates an abrupt change in pace. When it acts like a comma, it typically does so when it's giving information. It can also precede lists—products, information, etc.—and can be used after punctuation.
But notice how none of these uses felt like AI? That is because AI uses the emdash incorrectly; where a semi-colon would better serve its purpose, it defaults to the emdash—honestly, it will default to the emdash for simple things like commas!—and you'll be hard pressed to find it using the emdash in conversations.
So, my fellow writers, I encourage you to continue using the emdash... just avoid using it where different punctuation would be better suited.
