Right now there is no human, the data just goes nowhere (i.e. it is not used).

At some point we need to be optimistic and look for incremental progress.

No, I really meant structured. Extracting data from structured documents is surprisingly hard when you need very high accuracy.

What I mean by structured is: invoices, documents containing tables, etc.

Extracting useful data from fully unstructured content is very hard IMO and potentially above the capacity of LLMs (depending on your definition of "useful" and "unstructured")
