This is effectively the same issue as what’s going on in the paper and why I used it as an analogy.
Much like how maladaptive genes can piggyback on good genes, but then become overrepresented in an endogenous sample pool, small errors in the diffusion model end up exacerbated through subsequent generations without enough difference in ‘genes.’
There’s definitely good ‘genes’ in the diffusion model, but it’s not the frequency or abundance of the good genes that’s at issue, but the frequency of maladaptive traits in subsequent generations. Much like the issues with human reproduction.
