Standalone Complex is based on the idea that:
The Stand Alone Complex is a philosophical construct; A copy of something that does not exist, or to make it clear, a copy that does exist but the thing it copies (The Original) does not exist.
and also we have it in the Matrix.
But if we look closer at the 3rd stages of sign-order in "Simulacra and Simulation", we get the same idea and same plot setting.
The third stage masks the absence of a profound reality, where the simulacrum pretends to be a faithful copy, but it is a copy with no original. Signs and images claim to represent something real, but no representation is taking place and arbitrary images are merely suggested as things which they have no relationship to. Baudrillard calls this the "order of sorcery", a regime of semantic algebra where all human meaning is conjured artificially to appear as a reference to the (increasingly) hermetic truth.
Could we say the both series use this Idea?
