According to Soumith Chintala on Twitter, the widespread adoption of em dashes in AI-generated prose, particularly by ChatGPT, is influencing human writing styles and professional communication. Chintala notes that em dashes, once a personal stylistic choice, have become emblematic of 'soulless AI prose' as large language models like ChatGPT increasingly use them for sentence flow and clarity (source: @soumithchintala, Twitter, August 5, 2025). This phenomenon highlights how AI-generated content is shaping digital communication norms, presenting opportunities for businesses to refine brand voice and differentiate from AI-generated text. Companies in content creation, marketing, and AI tool development can leverage this trend by tailoring editorial guidelines to preserve human authenticity, addressing growing user demand for unique, non-AI style writing in business communications.
