I'm surprised this isn't a bigger concern given that:

For over a year now we've been at the point whereby a video of anyone saying or doing anything can be generated by anyone and put on the Internet, and it's only becoming more convincing (and rapidly)

We've been living in a post-truth world for almost ten years, so it's now become normalized

Almost half of the population has been conditioned to believe anything that supports their political alignment

People will actually believe incredibly far-fetched things, and when the original video has been debunked, will still hold the belief because by that point the Internet has filled up with more garbage to support something they really want to believe

It's a weird time to be alive
