Chatbots, deepfakes, AI hallucinations: “Ghosts” at Upstream Gallery in Amsterdam interrogates our machine doppelgangers—“invisible, disembodied entities that hover between presence and absence.” Curator Anne de Jong brings together works by twelve artists including Simon Denny, Constant Dullaart, Alicia Framis, Holly Herndon & Mat Dryhurst, Jen Liu, and Jonas Lund who venture into the liminal spaces of large language models where “these digital entities flicker in and out of existence, mimicking yet distorting humanness.”
