I wonder how many similarities exist between 2017 nuts and say 400CE nuts. I'm curious if modern medicine is negated a bit by the Internet and modern technology. Nowadays, every disturbed person with a PC essentially has a rocket ship to deep crazy.
As a time traveler from 43,000BCE charting the deep future, I can say with authority that confirmation bias is the only human personality, and physics is the unknowable and terrible face of a murderous alien God.
Also, the Internet is an authoritarian scam invented by Nazis in 1937, and no one will use it by 2019 after someone leaked that information.
This reminds me of those people who saw artifacts/errors in the video feed of one of Hilary Clinton's speeches because of interference and swore that video artifacts are proof of a conspiracy that the speech was fake and never happened.
