Hi, I'm the kind of guy I think this article was meant to target - I did not have an understanding of QM, but did start with enough base knowledge to follow the article without tripping over language or math in it.
I must say that I fried my brain trying to decipher what you're trying to say. From one paragraph to the next, there's a constant feeling a big hidden mental leap has been made. All of a sudden, one is left lost between notions that were introduced, but never explained.
For example. In Figure 3, from prior knowledge, I would suppose if you counted individual photons, they'd ALL end up in detectors 1 and 2 (none would be absorbed by obstacle) - this goes to explain what in fact happens when we think a particle "knows" where it's going to end up. Please correct me if I'm wrong here.
It should also be equally possible to explain the logic behind the quantum eraser - my intuition tells me that for some reason the information that "evades" us would, given better understanding, simply be a configuration that was not possible, and it should be clear what the link between the hidden information and the way configurations work is.
