[ExI] Planetary defense

[Anders Sandberg]

Thanks for your help. The talk went well, will likely show up on YouTube 
sometime in the future.

Overall, this conference is immensely cheering. This is a GCR we have a 
handle on. Sure, most deflection projects are still pie in the sky, but 
the surveys are getting close (~90% complete) for checking 
civilization-killers - we are likely safe from these, except for a small 
number of longperiodic comets. "The risk of surprise by a large impact 
has been completely retired". It is still probably worthwhile to develop 
the capacity to nudge things away and be prepared for the occasional 
airburst, but we do not need to fear the sky falling.

The irony is of course that solving an xrisk or GCR nets you rather 
little credit - nothing visible is happening.

Motto of today: "There is no such thing as free launch"
