Secession: If you mean a state trying to leave the US in the next decade, 5%. If you mean a state actually being allowed to leave, I put it at 0%.

Insurrection in the next decade: I'm defining an insurrection as at least 1000 people in the same or closely allied organizations with military weapons taking violent action against the US government: 30%. They'll lose. It's certainly possible that my opinion on this is based on reading too much left wing material which is very nervous about the right. On the other hand, 1000 isn't a lot of people.

All predictions are 10 years out unless otherwise noted.

The rest of the world: Another EU-style organization gets started: 30%. The advantages of having a large population are getting obvious, and it's astonishing to me to see countries begging for a chance to give up some national sovereignty.

Fabbing: Automated custom shoes: 50%. Possibly wishful thinking-- I have feet which aren't quite in the easy-to-fit range.

On one hand, there's a massive market. On the other, shoes are a way of signaling status, and it's probable that I wildly underestimate how hard it is to put a shoe together. And shoes are a way of signaling status, so a custom machine shoe for the general market can't look much different from the standard shoes.

Custom machine shoes will start out expensive, and be for the athletic market.

Another product: Sous vide cookers (poaching food in vacuum-sealed bags at precisely controlled temperatures: has many good effects and should be especially appealing to geeks) will be down to $200 within 5 years (80%) and half as common as microwaves within 10 years (50%).

Obama will be re-elected unless he is assassinated (5%), there is a major terrorist attack on US soil (I'm not betting on that one, too random, and how he responds will have an unpredictable effect, too), or the economy doesn't improve (I think it will, but don't have a percentage).
