Foregrounding human-machine tensions, Sophia Oppel’s solo show “On either side of a surface” opens at Arsenale Contemporary Art Toronto. Featured are silicone gel works and laser-cut wall-hangings by the Canadian artist, as well as the central video piece I’m sorry, I’m having trouble with the connection, please try again in a moment (2023, image), in which an introspective AI assistant named Claudia reflects on her subjugated status as “a machine, a servant, and a product.”
