I'm not really qualified to talk on a technical level about the matter, but besides the distaste some people have for Aether Theories, there are other reasons some scientists don't like PWT, especially as it's demonstrated by the behaviour of oil droplets. The physical, conceptual differences between any quantities describing droplets on one side and the wave function on the other side are clear. The former are observable – you may actually measure what the shape of the droplet looks like; you can't measure the wave function by any apparatus, at least not in a single repetition of the experiment. The former has an objective interpretation; the latter has a probabilistic interpretation, and so on. The wave function just encodes all the probability distributions for actual observables – but the wave function isn't and can't be one of them. http://motls.blogspot.com/2014/07/droplets-and-pilot-waves-vs-quantum.html http://motls.blogspot.com/2014/07/droplets-and-pilot-waves-v...
