Synthetic Reality, Uh, Finds a Way

In an age of synthetic reality, how do we have any idea of what is real or what to believe? It was bad enough in 2016, but now? How many different ways are we being shown and told things that may or may not be truth?

If a robot taxicab can be disabled with a traffic cone, and a female crocodile can parthenogenetically reproduce, is it possible for us to know what to accept as real and dismiss that which is unreal?
