Digital Photography and digital painting. Both were considered deeply offensive to a lot of artists. I have witnessed both first hand and the criticisms were verbatim the same as AI.

They said you couldn't become a good photographer if you didn't learn it with the limitation of film that forced you to make each shot count. Photoshopping a picture made it "not a real photo" and was banned from online communities and irl events, drawing in photoshop was not considered art. I find it very ironic that digital artists are repeating the exact same argument as the one used against their art
