"Hello World — For the Post-Human Age" at Art Tower Mito looks at developments in art in the context of digital technology and artificial intelligence. It starts with a lightly comedic farce, in the form of Cecile B. Evans' 2016 multimedia installation "Sprung a Leak." This three-act work, partly inspired by Shakespeare's "The Two Noble Kinsmen," tells an elliptical and intentionally glitchy tale of human users' distress when Liberty, their favorite animated beauty blogger, disappears and how a solution is patched together by well-meaning robots.
