Assume you were to gradually transform Google Maps into a seed AI, at what point would it become an existential risk and how? And why wouldn't you just skip that step?

A very important part of Google Maps is Street View, which is created by cars driving around and taking pictures of everything. These could be viewed as 'arms' of the seed AI, along with its surveillance satellites, WiFi sniffing for more accurate geolocation, 3D modelling of buildings, and the recently introduced building-interior maps.

Which is to say, Super Google Maps could be a gigantic surveillance network and pervasive examiner of every corner of reality so it could be as up to date as possible.
