You're about a hundred years late to be making this stand. I've never actually seen anyone claim that quantum physics in general is hooey. What do you even mean by that? That in fact, all of modern physics observations, as well as cosmology, materials science, etc, can actually be explained by classical physics? Or do you mean that you think there is some underlying classical/deterministic process which drives nature, and quantum mechanics is our attempt to predict outcomes based on an incomplete understanding? That is a defensible position, but it still wouldn't make sense to call quantum physics a waste of time.
