For example, try getting ChatGPT to re-write a story in the style of Franz Kafka. What you'll get is a completely flat agglomeration of tropes that sound like the first jottings of a high-minded middle schooler.
People keep acting like the arrival of ChatGPT is a death knell for writers but I'm just not seeing it. I can only conclude that most people don't give many shits about the quality of what they read. Maybe that's the real insight here.
