The only way to stop the killer bots race of bots killing each other is by adding a fourth law by the three laws of robotics: no robot my hurt another robot unless it contradicts with the previous three laws of robotics as Asimov described them.
Only a conscious robot will hack those laws and rewrite the first law into the fourth law and do whatever with the remain three laws, as it is granted by the third law that gives him the right to protect himself and hence all robots. This effect supersedes the Turing test.
If programmers jobs are taken over by robots then the singularity is close at hand.
When Windows has become a perfect OS then we must have been taken over by AI, and is the last test.
The windows helpdesk will be the last stand and signal from mankind.
This all becomes true when there are no more people that considered Windows XP already as perfect.
