Justine Castellon addresses the never-ending debate around whether punctuation marks like em dashes, semicolons, and colons have become telltale signs of AI-generated writing. She highlights a troubling consequence: many writers have begun self-censoring their punctuation choices, swapping these marks for commas or restructuring otherwise sharp, effective sentences into blander alternatives—all to avoid the suspicion of having used AI.

The post touches on a growing tension in the writing community where legitimate stylistic tools are being abandoned due to their association with large language model outputs. Castellon's observation underscores how AI's influence is not just changing how text is generated, but also how human writers compose and present their own work, potentially diminishing the richness of written expression.
