Does this analogy work? It's exceedingly hard to make new low-background steels, since those radioactive particles are everywhere. But it's not difficult to make AI-free content - well just don't use AI to write it.
It's not. It's just cheaper to salvage.
Training future models without experiencing signal collapse will thus require either 1) paying for novel content to be generated (they will never do this as they aren’t even licensing the content they are currently training on), 2) using something like mTurk to identify AI content in data sets prior to training (probably won’t scale), or 3) going after private sources of data via automated infiltration of private forums such as Discord servers, WhatsApp groups, and eventually private conversations.
E: Never mind, I didn’t read the OP. I had assumed it was to do with identifying sources of uncontaminated content for the purposes of training models.
