The only important and logical part of the article, and the answer to the puzzle of entanglement.....

“For example, if the first one is measured and collapses into the up state, the second one will instantly collapse into the down state, even if it’s light-years away.”

How do you know the first one "collapses" at all?

Which would mean a mechanism for FTL digital communication exists. If we ever colonize planets around other stars,FTL communication may mean the difference between a single civilization or a mankind that is fractured into multiple civilizations.

“For example, if the first one is measured and collapses into the up state, the second one will instantly collapse into the down state, even if it’s light-years away.”

Which is one of the reasons Einstein called it "Spooky". The "communications" happen "instantaneously", IOW, faster than the speed of light.

Understanding this on a deeper level might have all sorts of "interesting" consequences and applications.
