All films are fake, which is not a bad thing as virtually all art, like film, is fake, in one way or another as art is but a fabrication created by us rubes in an existence we will never fully understand. :)
Why Western sets? Well, they're the archetypical example of the fake as facades, as seen in the pix above, are needed to build out the "reality" of a western town in the most efficient way possible.
In writing this blurb, the notion of
AI as fake
comes to mind as its take on reality is like the Western set, all facade and no depth in its attempt to describe the vagaries of existence without the wealth of experience we all share as humans residing on a planet called Earth.
11 degrees, yet another fake by yours truly. :)
