It looks there's a difference this time: copying the details of other people's work has become exceedingly easy and reliable, at least for commonly tried use cases. Say I want to vibe code a dashboard, and AI codes it out. It works. In fact, it works so much better than I could ever build, because the AI was trained with the best dashboard code out there. Yes, I can't think of all the details of a world-class dashboard, but hey, someone else did and AI correctly responds to my prompt with those details. Such "copying" used to be really hard among humans. Without AI, I would have to learn so much first even if I can use the open-source code as the starting point: the APIs of the libraries, the basic concepts of web programming, and etc. Yet, the AI doesn't care. It's just a gigantic Bayesian machine that emits code that nearly probability 1 for common use cases.
So it is not that details don't matter, but that now people can easily transfer certain know-how from other great minds. Unfortunately (or fortunately?), most people's jobs are learning and replicating know-hows from others.
