Something to consider....

A 2009 experiment showed that robots can develop the ability to lie to each other. Run at the Laboratory of Intelligent Systems in the Ecole Polytechnique Fédérale of Lausanne, Switzerland, the experiment had robots designed to cooperate in finding beneficial resources like energy and avoiding the hazardous ones. Shockingly, the robots learned to lie to each other in an attempt to hoard the beneficial resources for themselves.

"The implication is that they're also learning self-preservation," Del Monte told us. "Whether or not they're conscious is a moot point."
