Is This a ChatGPT Hyphen — or Just Good Writing?

The article focuses on the evolving perception of the em dash punctuation mark amid advances in artificial intelligence (AI), particularly ChatGPT. It explains that the em dash, traditionally valued by writers for its versatility, has recently been stigmatized as a sign of AI-generated text, sometimes called the "ChatGPT hyphen." This shift is linked to AI models' frequent use of the em dash, reflecting its prevalence in source materials like books and academic papers. The article also traces the em dash's historical decline and resurgence due to technological changes and highlights concerns that AI detection tools may wrongly accuse human writers of plagiarism based on punctuation use.
