Right now I order my MS Laboratories engineers to invent a solution to exterminate all the class Arachnida. For anything that can go wrong, I'll put this poster:
Do not worry, this country is self-flammable, it burns itself.
Brief explanation.
--------------------------------------------------------------------------------------
We discarded all robots in the facility: Wheatley, GLaDOS, AUTO, HAL9000. Whenever a (artificial or not) intelligence is created, disasters occur on Earth.
For example, humans appear = pollute and destroy the Earth.
Appear artificial intelligences = destroy the earth and humans.
