I agree and it lines up with my experience (especially the last few months).
Thinking about the website design stuff, it really didn’t take me very long to start noticing. Within tens of generations I was starting to get annoyed with repetitions. I’d estimate I’ve generated less than 100 designs total myself (and often I’d get 5+ different designs at once). I think recognizing AI writing (excluding via popular heuristics) takes longer to develop.
Also, there are a lot of people out there who have interacted with AI a lot but not in the same way you or I would. Things like long chatgpt threads, AI companionship services, falling in love with AI, AI psychosis, etc. Would they develop the same skill? I am not sure.
