I don't know how society will function when it's as easy to fake a video or image as it is to draw a stick figure. Hopefully it at least means that people view what happened here as akin to scribbling boobs on someone's photo, but we're not there yet apparently.
Perhaps there is reason to be optimistic. If we believe nothing online, then digital inauthenticity may cause us to yearn more for authentic, in-person interactions. The modern web has not been without its warts. It's led society to some very unhealthy behaviors. It's telling that a lot of people think the internet is society, rather than a slice of it. Perhaps its decline is the correction society needed. It's easy…
But then again, perhaps we won't and things will just get worse.
