Yea.......the advancement of technology.
Consider a fake video that looks so real that only an expert analysis could tell the video is fake, being used to create panic among the masses.
For example.......a video of a big city mayor telling residents to leave the city immediately due to an imminent massive explosion in the city.
Or a "leaked" video of the POTUS advising politicians from "Air Force One" that an imminent nuclear attack by Russia is expected and to evacuate big cities.
Political interference by foreign entities, most notably during elections, advising people there are food shortages, anything that causes panic or distrust.
Russia has abandoned secrecy and wants people to know they are posting content, so they can claim being the only honest broker of information.
We aren't living in Dorothy's Kansas anymore.
