Since 52-year-old German artist Boris Eldagsen went public with the fact that he won a Sony world photography award with an AI-generated image, relations between him and the award body have soured. Sony have issued a statement, saying: "We no longer feel we are able to engage in a meaningful and constructive dialogue with him." His website reads: "Sony: Stop saying nonsense!" "I don't know why they behaved like this," he says, speaking to me from Berlin on the morning after the controversy broke. But I have a fair idea: plainly, they feel like they were conned, and had their aesthetic discernment called into question.
