Using Schrödinger's cat reveals that things can be in 2 states at the same time (and I reckon are influenced by the observer if the box is opened.) I understand how this illustrates how particles can exist in two states. But I'm not sure I understand the PRACTICAL implications of the experiment.

Is it kind of like x/∞, where any number divided by infinity is 0? In other words, does the cat example help theoretical physicists to help solve bigger problems, or is it an end in and of itself, to show that the particle can exists in two states? Like more of an illustration for people who don't understand quantum physics to understand it better?
