Both sides have valid points. AI tools can help with ideas, access, and productivity—but overall, they hurt creativity. Creativity comes from struggle: bad drafts, uncertainty, and thinking through language. When AI does that work for you, writers shift from creating to selecting. The result is cleaner writing, but flatter voices and less original thought.
It really depends on the context. If you need to structure the text or limit it to a certain number of characters, AI is the best tool for the job. But a human is still better at writing the text itself, since they have a better grasp of idioms and the human spirit.
