Hello stremba!!! Thanks for the fine presentation on protein folding. I have seen this hypothesis before, and it seems reasonable to me. But I've also encountered researchers who find it inadequate, generally speaking on adequacy of information grounds. (Such folks evidently think that biological processes are intensively "informed" processes.) So I gather this vital issue is still "a work in progress."
WRT your comment above: I just don't see there is anything necessarily "unnatural" about the presence of design in nature -- especially if the natural laws themselves are the source of the design.
Thank you so much for writing!
