An AI robot’s painting of British computer scientist and codebreaker Alan Turing has sold for $1.08 million, becoming the most valuable artwork by a humanoid robot ever to change hands at auction and raising new questions about the role of artificial intelligence in art.

Artists might still be wary and skeptical of artwork by artificial intelligence, but art collectors are seemingly on board. Sotheby’s recently held an auction for the first artwork made by a humanoid robot.
