Before anyone is panicking, please remind yourself that whatever medium was used by humans as a form of communication in the last few thousand years, was also used for fakes. You only need a half-decent voice actor to pretend you are someone else on the phone. Fake photographs are as old as photography. Even the probably most immediate form of interpersonal communication, seeing another person, can be faked, which is demonstrated by the many Doppelgängers used by politicians in the past. The power of the house Habsburg basically had its roots in several imperial documents and bulls faked by Rudolf IV. in 1358 (which was only discovered in the 19th century).
This isn't a new phenomenon that now means that we cannot trust anything anymore - it's only that the fakes are finally catching up with live video.
