Perhaps the metacrap fallacy isn't true in the age of LLMs.

The metacrap fallacy was "Once users have put enough meta-structure on their data, all kinds of automatic things will become possible."^[ka][kb]

But fitting things into an ontology up front is a massive amount of work, and the benefit is only theoretical and indirect.

So the direct cost beat the indirect benefit and made it so no one ever did it.

But now LLMs can be used to auto-structure information after the fact.

LLMs don't get bored, so they could do the structuring even if a human would die of boredom.

It's totally possible that the reason the metacrap fallacy was true was not "it wouldn't be valuable if you didn't have structure in the information" but rather "it's too much of a pain in the butt to structure things."
