Ars Technica has fired its senior AI reporter, Benj Edwards, after he included AI-fabricated quotes in an article, which was later retracted. Edwards took responsibility for the error, citing his use of an experimental AI tool while working from home with a fever. The incident has sparked a discussion about the use of AI in journalism and the importance of fact-checking. The publication has announced plans to publish a guide on its use of AI in the coming weeks.
