Tony Veale, a computer scientist who wrote a book on comedy and A.I., “Your Wit Is My Command,” is impressed with new large-language models’ ability to imitate genre and voice, analyze and generate metaphors, explain itself and even admit mistakes. He’s bullish on computers making professional-level jokes in five years and when asked about originality responded that A.I.’s process isn’t any different from that of young artists. “Many comedians, such as Eddie Murphy and Jerry Seinfeld, trained themselves by repeatedly listening to and repeating Bill Cosby’s early comedy albums,” he wrote in an email. “We all learn from those we aim to emulate and transcend.”
