There’s a community in which people post examples of an AI image generator messing things up. I think that’s what they mean by “ai-images failing”. I think they’re saying: “you may think that by posting to such a community you are being critical of AI generators, but in fact you’re still filling your head with AI noise.”
A lot of times the problem I had was that I didn’t sufficiently understand something from a week or two ago. So to clear up my confusion, the teacher would have had to stop the class and let me work through a couple examples of previous work till I understood it. (yes I’d study between classes too.)
