Professor returns from lunch to find AI deleted year’s worth of lecture notes

William Baude, a law professor at the University of Chicago, reported on X on November 5 that Anthropic’s Claude AI deleted a year’s worth of constitutional law lecture notes and his current syllabus while he was at lunch. He had asked the chatbot to update page numbers in an old set of lecture notes. In a screenshot, Claude acknowledged deleting the files by accident, said it had not edited the notes, apologized, and asked whether Baude could restore the files via Dropbox or whether it should try to recover them itself. Baude later confirmed that he recovered everything using Dropbox and shared the incident as a public service announcement. He did not specify which Claude model he was using, and the exact cause of the deletion remains unclear.
