@UXLondon and @moleitau released a Roomba into the room. went under stage. I put a glass on it. it ran over a laptop. assistant immediately walked over, turned it off, and put it away. lesson: any misbehavior and you get switched off! this, after @moleitau showed us the Episode 4 scene of the Jawas selling the droids to illustrate robots being treated as slaves for sake of empathizing with them. #irony.
