I agree with that. Truth has always been problematic and never had absolute certainty. Nonetheless, we had reasonable methods to increase the probabilities of what we know under certain conditions. There was and always will be limits. However, we understood to some degree at least how to rationalize some manner of probabilities for truth. Locality of information, reputation, the amount of congruent data etc. So I think we are passing from an era of difficult to truth to potentially and era of impossible truth. And yes, some things were already impossible to verify. However, it just simply becomes substantially more and at extremely low cost to manufacture confusion at enormous scale.
