Very surprised none has linked to this yet:
TL;DR: AI is a very underfunded existential risk.
Nothing new here, but it's the biggest endorsement the cause has gotten so far. I'm greatly pleased they got Stuart Russell, though not Peter Norvig, who seems to remain lukewarm to the cause. Also too bad this was Huffington vs something more respectable. With some thought I think we could've gotten the list to be more inclusive and found a better publication; still I think this is pretty huge.
If a few decades is enough to make an FAI, we could build one and either have it deal with the aliens, or have it upload everyone, put them in static storage, and send a few Von Neumann probes faster than it would be economical for aliens to send them to catch us if they are interested in maximum spread, instead of maximum speed, to galaxies which will soon be outside the aliens' cosmological horizon.
