There; now the statement is far less vague and handwavy, because I'm making a specific claim that is, AFAIK, well-understood.
Also, you seem to have misunderstood me a little. I didn't mean "prove me wrong", I meant "If I'm missing something, please tell me about it." More of a conversational request than staking a claim in an argument. Many people at HN seem to like to take argumentative, debate-competition stances — but I usually prefer more "Hey, let's discuss this interesting idea, point out mistakes each other is making, and learn together" kind of interactions. That's what I was asking for.
Well, I guess the answer isn't too different. I believe model collapse is a limitation of the current AI tech but maybe not the future ones. You can see humanity as a huge model that trains itself. What is novel about AI is that we built a machine with some intelligence traits that is free of biological constraints. If we can emulate the aggregate intelligence of a civilization inside a machine, it could improve itself forever but at a much faster pace.
