Now I though think it should be derived apriori, like, as toy model: LET there is 1B people, average can have 1 idea/day, 1 of 1K 100 idea/day, 1 of 1B 1M idea/day, you have 84000s/day and need 84s/idea for comprehension. THEN 1 of 1K has only 1⁄10 his ideas created by him, so priors to meet somebody with more created ideas than read are lower than 1/1K, AND just the average people create 1M times more ideas than can be read, at best you will know 0.0001% of ideas your world has.
