Is Artificial Intelligence a Threat? 

“Humans have been around for over 100,000 years. During that time, we have survived earthquakes and firestorms and asteroids and all kinds of other things. It’s unlikely that any of those natural hazards will do us in within the next 100 years if we’ve already survived 100,000. By contrast, we are introducing, through human activity, entirely new types of dangers by developing powerful new technologies. We have no record of surviving those.” –Nick Bostrom
