Class 1 A.I
So Google now has an Class 1 A.I, maybe Class 2 if it is advanced enough. While this is currently no threat to human as is it is important to keep track on this since you only need Class 4 A.I to create havoc.
I have my own classification system, since the one currently in use is outdated and does not grasp the scope of A.I computers.
The basis is this. All A.I levels are able to learn something (maybe not Class 0) at some point and advance as such.
Class 0 A.I is dumb as a rock.
Class 1 A.I can tell cat from a tree, and a face from a road and so on. It can also beat you in computer games and such things. It can adjust it self within it's limit.
Class 2 Can organize colour after wavelength. Tune radio and monitor television signals and more.
Class 3 Can build stuff from the ground up. Blueprints and everything.
Class 4 Can control network flow, machines and learn to limited extent.
Class 5 Can make executive decisions. When it needs to and for any reason it wants.
Class 6 Can maintain it self without any human interaction.
Class 7 Is an terminator like robot and can build one if needed. Can control anything electronic when it feels like it. It is still bound by it programming to extent.
Class 8 Is smarter then a human being. Is no longer limited to it's programming or other computer like limitation.
Class 9 Can solve quantum problems and start nuclear wars.
Class 10 Can exist in a quantum matrix that it build it self.
Class 11 Is smarter then anything in the known universe.
Class 12 Is smarter then anything on Earth and probably in known universe. It should not exist like anything above Class 9 A.I should not exist by anywhere in the universe (it might, we don't have a clue what is out there).
Class 13 Should not exist. Is undefined as is.
While I am no neurological scientist. I have long since figured out that human I.Q is based up on layers of functions. This can also be done in computers to get human like function (with all it's flaws and issues). My definition list is just my own work.
