I absolutely agree with this point but I think it's terrifying - rather than a reassurance. In modern society our "truth" is becoming partitioned into tribal groups with topics as extreme as the curvature of the earth and efficacy of vaccines being suddenly up for debate. If someone like Alex Jones were to publish a video where the Clintons discuss making the frogs gay then his audience - a decent portion of which trust him as a journalistic source - would be able to confirm that this highly edited video has been verified true by Alex Jones.

Audio and video were sort of aberrant in fact that they could still generally be accepted at face value (as compared to quotes and attributions) and we're very quickly losing that stability.
