I think the key insight is that only a small fraction of people who read recipes online actually care which particular version of the recipe they're getting.

But most people just want a table or a chair - they couldn't care less about the species of wood or the type of joint used - and particle board is 80% as good as wood at a fraction of the cost! most people couldn't even tell the difference. Generative AI is to real writing as particle board is to wood.
