I can't believe they didn't cite the 1890 Harvard Law Review article, by Louis Brandeis and Samuel D. Warren, "The Right to Privacy" where the future Supreme Court Justice wrote, ""Instantaneous photographs and newspaper enterprise have invaded the sacred precincts of private and domestic life; and numerous mechanical devices threaten to make good the prediction that "what is whispered in the closet shall be proclaimed from the house-tops.""[1]
When deep fakes improve enough to be hard to tell apart from real footage, we will eventually get a functional equivalent of the status quo before cameras, as footage from real events gets lost amidst the noise of fake ones.
That's far from clear. Even just screenshots plain text snippets are often strongly assumed to be true and are difficult to deny even though it's utterly trivial to fake them[1].
Even with Sufficiently advanced deep fakery they'll never be easier to create those fakes than text and the text is already strongly presumed to be real even if denied.
