And in that context, I think we want people to cooperate and satisfice (reduce existential risk) rather than quibble and all try to create personal eucatastrophes. So I'm not sure the terminology helps.

I tend to agree that the main point of leverage over the future will be whether there is a long future. However I think focusing on the risks may focus attention too much on strategies which address the risks directly, where we would be better aiming at a positive intermediate state.
