I really like your post, I did not know about deep fake videos. One thing for sure is that everything seems to be able to be faked in one way or another.

One form of cure is learning about critical thinking which helps identify fact vs propaganda.

The other is simple logic. Consider the recent news "Russia cleaned up the chemical attack" Really? You can't just sweep layers and layers of dirt up from a town and haul them away. They are generally no able to be cleaned up at all and are evident 10 years later in trace samples.
