What is the Uncanny Vally? Well if we go to Wikipedia we get:
The uncanny valley is a hypothesis in the field of robotics and 3D computer animation, which holds that when human replicas look and act almost, but not perfectly, like actual human beings, it causes a response of revulsion among human observers. The "valley" refers to the dip in a graph of the comfort level of humans as a function of a robot's human likeness.So how do we enter the Uncanny Vally in Satire. Well how about we go to The Onion Romney Proudly Explains How He's Turned Campaign Around: 'I'm Lying More,' he says
Romney has pulled even with President Obama, and the former Massachusetts governor credits his rejuvenated campaign to one, singular tactic: lying a lot.
“I’m lying a lot more, and my lies are far more egregious than they’ve ever been,” a smiling Romney told reporters while sitting in the back of his campaign bus, adding that when faced with a choice to either lie or tell the truth, he will more than likely lie. “It’s a strategy that works because when I lie, I’m essentially telling people what they want to hear, and people really like hearing things they want to hear. Even if they sort of know that nothing I’m saying is true.”
“It’s a freeing strategy, really, because I don’t have to worry about facts or being accurate or having any concrete positions of any kind,” Romney added.
There you have it, satire that is so spot on that it seems less like Satire and more like reality, leaving us with a very very uncomfortable feeling, a revulsion that the line between reality and nonsense is being erased and we are worse off because of it.
