The idea of a 2023 study "informing" a 1965 publication is a fundamental failure mode in understanding how information works.
Information doesn't travel backward in time; a retrospective analysis can only validate or contradict what came before, not influence it.
The Ritchie and Roser data simply offers an empirical look at historical trends, aligning with observations Moore made much earlier.
To claim otherwise is like saying a film review written today somehow changed the director's choices during the original 1960s production.
