That is mostly true, the field of robotics and gaming see this to be more prevalent since both are transitioning through some creepy levels of the uncanny valley. At it's core it's a hypothesis in the field of human aesthetics which holds that when human features look almost, but not exactly, like natural human beings, it cause's observers to wig out. The "valley" itself refers to the dip in a graph of the comfort level of humans as subjects move toward a healthy, natural human likeness described in a function of a subject's aesthetic acceptability. I joke that the drawing above hits the valley dip hard since Spike, Twilight, and Pinkie have human characteristics that normally in the show we tolerate because they are "cute" humanistic... this however is "creepy" humanistic heh (I kinda like the artistic take though ha!). But ya in the end for a while here as robots and video games become more prevalent in our life's the uncanny valley will be closely associated with it and not its broad definition as a whole.The irony is... the term was first coined in Japan by some professor (I can't remember his name) about robots ha!
