'Alexa, Improvise' is a comedy show that uses AI fails for laughs

It was 7:55 p.m. on a Saturday night, and I had just arrived at a small improv workshop and stage space in San Francisco's Mission District. Mere moments after I sat down, someone placed a stool in front of the stage, draped a red cloth over it and placed what would turn out to be an integral part of the evening's performance: an Amazon Echo. It wasn't there to tell jokes -- it's notably not a very good comedian. Instead, it was both prop and participant in a unique improv show called "Alexa, Improvise." From mechanical comics to riffing robots, the integration of artificial intelligence and comedy have been attempted before, with varying degrees of success.
