For example we have 5 statements sourced by some authoritative book. All is good, I can take the book and verify the statements manually. After some time we have 50 statements sourced by 10 different authoritative books. Situation becomes worse because I need high number of energy to verify the claims. 1000 statements and 200 books make the data unverifiable in practice. We have 65 000 000+ statements now. Current rule edition does not suggest any approaches to make this statement set verifiable. — <a href="/w/index.php?title=User:Ivan_A._Krestinin&action=edit&redlink=1" class="new" title="User:Ivan A.

At least until artificial intelligence is not created. For example I need birth dates of all Russian scientists for my scientometric investigation. And I want to verify this dataset before usage. How many efforts is needed for this simple verification task in case of books and other classical sources? My raw estimate is one or two human-year. So this data subset is verifiable from formal point of view, but is not verifiable in practice. — <a href="/w/index.php?title=User:Ivan_A._Krestinin&action=edit&redlink=1" class="new" title="User:Ivan A.
