You never should have. Large amounts of work, even stuff by major authors, is ghostwritten. I was talking to someone about Taylor Swift recently. They thought that she wrote all her songs. I commented that one cannot really know that, that the entertainment industry is very going at generating seemingly "authentic" product at a rapid pace. My colleague looked at me like I had just killed a small animal. The idea that TS was "genuine" was a cornerstone of their fandom, and my suggestion had attacked that love. If you love music or film, don't dig too deep. It is all a factory. That AI is now part of that factory doesn't change much for me.
Maybe my opinion would change if I saw something AI-generated with even a hint of artistic relevance. I've seen cool pictures and passable prose, but nothing so far with actual meaning, nothing worthy of my time.
