The Copenhagen interpretation of quantum mechanics is nowadays the interpretation that prevails over other interpretations (or theories). Basically, it states that all processes in Nature are inherently probabilistic. Contrary to, for example, the pilot wave theory, of which Louis Victor Pierre Raymond, 7th Duc de Broglie and David Bohm (who revived the theory) are proponents. This theory sees Nature as inherently probabilistic. Quantum stuff is seen as governed by the deterministic motion of a wave accompanying the stuff (like a Brownian particle is accompanied by the fluid it moves in). So, such a theory (it's not an interpretation, I guess) explains the strange behavior of stuff in quantum mechanics by the introduction of maybe even stranger things as a pilot wave or hidden variables (introduced by Bohm).
Now I can imagine that this vision could be taught in present-day schools or where ever. But this isn't the case. The Copenhagen interpretation rules supreme, so to speak. Why is this? Is it because a bunch of physicists (like Bohr, Heisenberg, and Born) decided in Copenhagen that this view should be the view? Einstein struggled against the view (god doesn't play dice) but to no avail. Was it powerplay that decided the faith of quantum mechanics?
