I think what people usually refer to as Quantum Mechanics (i.e. Quantum Inference) will likely go the way of Maximum Entropy. Maximum Entropy originated as a physical concept and was eventually shown to have an origin in Information Theory and is now very important to fields outside physics. Applications of Quantum Inference outside of the traditional physics applications are being developed (see http://uk.arxiv.org/abs/0810.5290 and http://rspb.royalsocietypublishing.org/content/early/2009/03...).

Quantum Mechanics is not yet completely understood as an inference method so people confuse it with physics and Shrodinger's cat silliness results.
