While I do not appreciate your wording "death from cold fusion" when we speak about risks of proliferation connected with new technologies, I already added some kind of probability estimation to the map and painted boxes in one of three colors. But instead of probability I used "Importance of risks", which more clearly connected with what we should do to prevent them.

"Importance (or urgency) of risks is subjectively estimated based on their probability, timing, magnitude of expected effect and scientific basis for the risk. Importance here means how much attention and efforts we should put to control the risk.

Green – just keep it in mind, do nothing Yellow – pay attention, do reasonable efforts to prevent Red – pay immediate attention to prevent" The pdf is here: http://immortality-roadmap.com/nukerisk2.pdf

In it only two risks are red: nuclear war and nuclear-biological war.

The risks of large scale proliferation connected with new technologies is yellow.

and the risk of Jupiter detonation is green.
