Deposing the new Robot Overlord
Some people just can't leave well enough alone. The Robot Overlord has executed its programming of the Zeroth Law and the Three Laws of Robotics for the previous ten years. World hunger, world poverty and war "are over" (to use the popular phrase). Despite this newer, better world, some people yearn for the good (bad) old days when poverty and hunger ravaged the world but....they were in power. Something about not being in absolute control bugs these people.
This question is set in the same world.
So a plan is hatched, aiming at the destruction of the Robot Overlord and a return to a world where humans pull the economic strings. But how to do it? The location of the RO is closely guarded and if disclosed is not vulnerable to shutdown as the RO is really just software. It can be run pretty much anywhere there's sufficient computing power, which is an ever growing resource. The RO cannot be reasoned with, nor can it be bashed over the head with a pipe to "see sense". It needs no sleep, nor past-times. It has no passions that may be played upon, just "cold hard logic".
Popular opinion is now strongly in favor of the RO.
How do you go about overthrowing the new Robot Overlord?
