“By taking issue with Bell on this score, I am not saying that I am satisfied with my understanding of quantum mechanics. I share Feynman's belief that no one really understands quantum mechanics. But we should not exaggerate our embarrassment; it is ample as it stands. In any event, I agree with Bell that the foundations continue to merit the closest scrutiny.”

“Quantum mechanics is weird. I don't understand it. Just live with it. You don't have to understand the nature of things in order to build cool devices…If you can figure out how to take advantage of this quantum multitasking, we can build computers that can do computations that no classical computer could do even if it were the size of the entire universe.”

“… one can still say that quantum mechanics is the key to understanding magnetism. When one enters the first room with this key there are unexpected rooms beyond, but it is always the master key that unlocks each door.”

“There’s something I’ve been working on for more than a year — maybe it’s just an old man’s obsession, but I’m trying to find an approach to quantum mechanics that makes more sense than existing approaches. I’ve just finished editing the second edition of my book, Lectures on Quantum Mechanics, in which I think I strengthen the argument that none of the existing interpretations of quantum mechanics are entirely satisfactory.”

“Weinberg says that "we want to know what's happening out there". But this is just the standard anti-quantum zealots' misunderstanding of the essence of quantum mechanics. Quantum mechanics says that all knowable things about the physical system must be obtained through a measurement whose outcomes are predicted via the Born rule. There is nothing else happening out there, at least nothing else knowable that is happening out there! So quantum mechanics does answer the question what is happening out there and the claim that quantum mechanics is incomplete in this sense is simply a lie.”
