Lots of things could happen. Gamma Ray bombardment sterilisation of the solar system for example. That's the set up for the main plot of Greg Egan's "Diaspora".
But since neither becoming a Gleisner Robot nor Polis Citizenship are possible for me it's futile to spend time worrying about a nearby Gamma Ray burst. If it happens I would likely die instantly, but even if not there's no reason to plan for that.
I care about contingency planning a great deal but it makes no sense to plan for events which are both extremely unlikely and very difficult to successfully ameliorate.
