The Download: how AI affects creativity, and CRISPR babies

Generative AI models have made it simpler and quicker to produce everything from text passages and images to video clips and audio tracks. But while AI's output can certainly seem creative, do these models actually boost human creativity? That's what two researchers set out to explore by studying how people used OpenAI's large language model GPT-4 to write short stories. The model was helpful--but only to an extent. They found that while AI improved the output of less creative writers, it made little difference to the quality of the stories produced by writers who were already creative.
