The terror of AI has come to comedy. There are a dozen shows this year about the threat that technology poses to the way we live, laugh, and love. There's a fine line between surrealist comedy and utter nonsense. It does produce a steady stream of chuckles but suffers by being presented in an airless yurt. The highlight for me was the confession that the comedian has "a rare form of synaesthesia which allows me to literally see colours!"
