No matter how smart both of them think they are, egotistical arrogance is their downfall. Thiel falls back on cherry picked Bible verses to create fear, do it my way or the boogeyman Antichrist is gonna get you. A false perception. I suggest you read the whole ministry Apostle Paul gave to the Thessalonians - and see if you come up with the same result. This gives perspective.
Thiel's comment about Elon Musk's outlook on the future is disturbing. A brighter note - Musk is not into stagnation.
Both are fighting for control of the masses. That is the real issue.
