I don't know what Google's attitude is to these things, but if it's bad then either they aren't listening to Peter Norvig or they have what they think are strong counterargument...
My guess is that most people at Google, who are working on AI, take those risks somewhat seriously (i.e. less seriously than MIRI, but still acknowledge them) but think that the best way to mitigate risks associated with AGI is to research AGI itself, because the problems are intertwined.
So I know we've already seen them buying a bunch of ML and robotics companies, but now they're purchasing Shane Legg's AGI startup. This is after they've acquired Boston Dynamics, several smaller robotics and ML firms, and started their own life-extension firm.
Is it just me, or are they trying to make Accelerando or something closely related actually happen? Given that they're buying up real experts and not just "AI is inevitable" prediction geeks (who shall remain politely unnamed out of respect for their real, original expertise in machine learning), has someone had a polite word with them about not killing all humans by sheer accident?
