I can't call it something other than the flamzboo event, since we don't know what it is. The clearest picture one can have of what this event potentially is is by considering events which would have similar impact but are currently fringe in terms of public consciousness such as:
- Supervolcano eruptions
- Asteroid impacts
- AI takeoff
- Engineered bio weapons
- Autonomous lethal weapons
- Commoditized, small nuclear weapons
These are not the things I'm talking about, since they have some level of consciousness, but are the closest examples since they are not top of mind in the public consciousness but are confer high x-risk. The ones I worry about are the ones that we can't know currently, that may be lurking on the horizon. One doesn't have to look far back in history to recognize these problems are typically the ones we get hurt by: surprises.
