Points and comments are a snapshot, not live.

A writer passionately defends the em dash against AI detection fears.

The author celebrates the em dash as a tool for clarifying, adding caveats, and creating dramatic pauses mid-sentence. They argue it is more assertive than parentheses, colons, or ellipses, and more useful than semicolons. To avoid AI suspicion, they recommend AP-style spacing around the em dash, which AI does not default to. The piece also offers writing coaching for $175 per hour.

What commenters are saying

Commenters largely dismiss the AI-em dash panic as a niche online obsession. One says the only people who care are "losers on Tumblr and commenters on fanfiction sites." Others note that form-based AI detection is error-prone. A split emerges: some worry about AI co-opting style, while others argue substance matters more and suggest writing however you want. A few defend the double-hyphen as an alternative.
