What are the threats we face as a society?

The following could be a preliminary list. Are there others that should be included? And how should these threats be ranked?

1. "Soft" Coup - E.g. a remake of the election's overthrowing attempt that culminated in the election de-certification push followed by the assault on the Capitol on January 6, 2021. Or massive gerrymandering. Or radical changes to the manner of appointing Electors... The possibilities are endless.

2. Military-Civil Coup - It has never happened in the US before (but neither was a "soft" coup attempt deemed likely); could it happen in the near future?

3. Civil War 2.0 - Whether it's the secession of either "Red" or "Blue" States, as some high party officers and talking heads seem to be encouraging, or explicit calls to an all-out war, how likely is it?

4. Great Depression 2.0 - Fortunes have been made predicting the next big economic downturn, but could it happen? How to prevent it?

5. Heightened social unrest - Can the faultlines in the American society deepen and in so doing erode the rule of law and cause widespread and escalating violence?

6. Disasters - Climate-change-induced, health crises (pandemics), domestic terrorism, international terrorism, war... Pandora couldn't keep them all boxed in - What can be made to prevent them? And how to prepare for them?
