 CAPTCHAs run by Google are also used to train artificial intelligences to get better at these difficult tasks, such as reading poorly-scanned text or identifying objects of interest on the road (the latter being the subject of [[1897: Self Driving]]).

 :If the robot uprising includes the use of weapons of mass destruction (as in the ''{{w|Terminator (franchise)|Terminator}}'' franchise, or as was threatened in ''{{w|WarGames}}''), then only a hardened military structure is likely to survive.
 ;Car
-:Cars offer some shelter and, more importantly, mobility in one convenient package.  Most families own at least one, and they are widespread in human-occupied areas, so even if the car is not as suitable as a long-term shelter (depending on how the road and gasoline/power networks survive the uprising) it makes a fine first step in evacuating to a more permanent hiding place.  This is of course assuming that the car is not self-driving and that hostile self-driving cars are not widespread.

 ;City
 :Cities offer thorough selections of supplies and tools that may be harder to come by in more rural areas, but they are also home to lots of robots and automated systems that may participate in the uprising, not to mention humans who may be prime targets for the machines.  It may be necessary to visit the city to stock up on supplies in a post-apocalyptic scenario, but in the early stages of a robot uprising, it is best to leave them as quickly as possible.
