This meme is about the difference in scales. When your electron’s delocalization is much greater than other scales in your system, the electron behaves like a wave. Otherwise if the electron’s delocalization is the smallest scale, it behaves like a particle.

If you can look at the setup of an experiment with your bare eyes, the electron behaves like a particle. If you cannot - it may behave like a wave.

You can see wave properties from a double slit setup with your bare eyes. Here’s someone who did it with a cardboard box.

If you setup a detector that measures which path the particles took, the interference pattern disappears- again something you can see with your bare eyes.

  For electrons you can’t do it. Either way the interference is not a quantum effect and the detector that you are talking about is a simple reemiting device that detects the wave vector and creates the wave in the same direction. Now live with that.

    Why are you giving me a theoretical paper? It doesn’t even have sizes, but I assume that the distance between two holes is about 1um, which you cannot see with your bare eyes
