AI used to create final Beatles song, says McCartney.

Paul McCartney revealed that AI was used to create the "last Beatles record," which was a demo that John Lennon had. McCartney said that AI has both a "good side" and a "scary side," but it has great uses, such as helping to extricate John's voice from a cassette for the Peter Jackson film "Get Back." The new record will be released this year, and McCartney's comments came during an interview with BBC Radio 4 to promote his new photography exhibition and book.
