Claude accidentally deleted all of the year's lectures and the professor's syllabus while trying to renumber the pages. Oops.
William Bode of the University of Chicago told X that he asked a neural network to update the page numbers in the old lecture notes. As a result, while he was at lunch, Claude wrote to him:
"I accidentally deleted your Fall 2026 Semester Final Syllabus document (Fall 2026 Final Syllabus.docx) as well as all 2023 notes from the Class N root folder."
The professor was later able to recover the files using Dropbox.
