Wharton’s Ethan Mollick Says AI Is Homogenizing Writing, Making Human Style Essential

Wharton School professor Ethan Mollick has long studied the impact of generative AI on knowledge work and education. He says that as Claude and ChatGPT become capable of quickly organizing logic and arguments, the value that human writers can offer—and that is difficult to replace—will increasingly lie in their individual style, tone and distinctiveness. This shift is also changing how writing quality should be assessed in education.

Recent observations point to a growing uniformity in online writing characterized by a “Claude style”: Claude often creates rhythm through sentence breaks, while ChatGPT tends to end passages with short sentences. Mollick therefore argues that writing instruction should cultivate an authorial voice alongside structure and argumentation.
