The Em Dash Death Certificate

Kamil Banc explores how the em dash, a 300-year-old punctuation mark, became a telltale sign of AI-generated content due to overuse by language models. The article traces the mark's history, explains why AI overuses it, and offers practical alternatives like colons, semicolons, and varied sentence structure. The broader lesson is about recognizing and breaking predictable AI writing patterns to keep content authentically human.

Lead claim

AI overuse turned the 300-year-old em dash into a predictable tell of machine-generated writing

Atomic Claims

What this article supports

Claim 1 · Source summary

Origins of the Em Dash

The em dash originated in the 1700s when printers measured it against the width of the letter M.

Claim 2 · Source summary

How AI Learned Dashes

Machine learning models learned to use em dashes after identifying them frequently in engaging conversational content.

Claim 3 · Source summary

Writers Abandon the Dash

Real writers started avoiding em dashes to dodge the AI label, killing a useful punctuation mark.

Claim 4 · Kamil's interpretation

Human Alternatives Recommended

Kamil Banc recommends colons, semicolons, parentheses, and full stops as human alternatives to overused em dashes.

Claim 5 · Kamil's interpretation

Edit AI Output Ruthlessly

Banc advises editing AI output ruthlessly, cutting every second dash, and varying sentence length.

Supporting context

The article blends historical narrative with practitioner observation rather than formal research, tracing the em dash from 1700s printing practices through its adoption by writers like Emily Dickinson to its current status as an AI writing tell. Banc's central argument is that machine learning models absorbed em dash patterns from engaging human content and now deploy them on a rigid schedule, making the punctuation a recognizable signature of generated text. For practitioners, the takeaway is practical: when using AI to draft content, ruthlessly edit output, cut repetitive dashes, vary sentence length, and replace formulaic transitions with line breaks. The broader principle extends beyond punctuation, since overusing any technique turns it into a detectable signature. Writers working manually should also self-assess whether their paragraph structures and transitions have become predictable habits.
