An AI walks into a bar... Can artificial intelligence be genuinely funny?

Karen Hobbs was more nervous than usual before this particular gig. A well-known circuit comedian, she's accustomed to the UK's often bruising stand-up comedy scene. It's eclectic, unpredictable and famously short on pity-laughs. Hobbs has tackled some of the most unforgiving rooms in Britain, from major London theatres to the back rooms of rural pubs. She has even triumphed within the dreaded competition circuit, in which a merciless audience votes in a gladiatorial popularity contest for the funniest gags.

But this Thursday night in late June, above the Covent Garden Social Club bar in Central London, Hobbs was about to attempt something totally new. She would take to the stage equipped not with her usual material, but with a stand-up set written for her by the AI platform ChatGPT. Most daunting of all, she would follow three comedians doing their actual, human material.
