What if I told you that all it would take to shut down the majority of the world is an AI that understands the market (newest AI can learn a game and in 4 hours be inhuman) and in roughly 24 hours be smart enough and understand the market as a fluid object enough to intentionally collapse the prices (think cryptocurrency). If the AI had enough time to study the market it could not only predict the market better than any human in existance but it would be able to control the entire market if only it had enough money to choke out the rest of the people ""hodl'ing""
