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.
