"In the last twenty years of his life, Einstein's continued challenging of quantum theory was often dismissed as his being out of touch with modern physics. He was indeed wrong in denying the reality of the "spooky action" he discovered to lurk in quantum theory. Its existence, now called "entanglement," has been demonstrated. Nevertheless, Einstein is today recognized as the theory's most prescient critic. His constant claim that the theory's weirdness must not be brushed aside is borne out by today's proliferation of wild interpretations of quantum theory."
