There's an underlying problem of much longer standing than CGI or DeepFake technology or whatever else. It's that people have nearly no awareness that they might be being deceived.

There are many, many historical photos all the way back to the Civil War (which nearly takes us back to the invention of photography) that are fake. How could they possibly have withstood scrutiny all these decades, long before any modern tech was available to create near flawless phonies? Simple: they were never, ever scrutinized.

The problem is actually even deeper than that. You can point out the obvious flaws and they still do not "get it". Why? Not quite so simple as the last: their worldview--because of fear and/or limits to their imaginative ability--cannot accommodate even entertaining the concept that they have been so universally deceived.

Everyone chooses their own reality, and they cling to it like a man in the middle of the ocean clings to a floating door. Few can bring themselves to let go and try to swim on their own, or even just stand up and realize the water was only four feet deep to begin with. They rant and curse at any who do so as idiots or madmen.
