Can you explain what you mean?

When I think of wave-particle duality, I think its just the expression of 2 facts. Matter waves show interference effects. Matter waves are only ever observed in a definite position, never in a superposition.

But position isnt special right? We never observe a superposition of momentum (move at 2 speeds) either. And neither are macroscopic states, we never observed an (1/sqrt(2))(alive + dead) cat either.

So evolution isn't observation and intermediate states aren't real.
