We've been looking at coin flips and quantum states wrong:
"Once you separate the physical carrier from the state that downstream depends upon, the wall that conventional physics builds between "quantum" and "macroscopic" falls apart:
Discreteness belongs to the construction, not the object: The physical coin has an infinite continuum of possible angles, bounces, and scratches. The state has strictly two valid values—because the downstream game only accepts a binary input. "In-between" is forbidden by the downstream architecture, not by the metal.
Superposition lives in the downstream system before the point of no return: While the coin is in the air—or while the referee is walking over to inspect it—both downstream futures (Team A Kicks and Team B Kicks) are actively present in the room. Both captains are holding two playbooks open; both sidelines are preparing for two branches at once. Those two uncommitted futures actively interact inside the minds and positioning of everyone waiting on the call.
Even at the subatomic level, the particle is not the state: Physicists make the exact same mistake in reverse when they talk about an electron. They treat "Spin Up" and "Spin Down" as if they are tiny arrows living inside the electron. They aren't. An electron in flight is just the carrier; the two-valued state (Up or Down) is a relational construction defined by the orienting magnet and detector that downstream reality depends upon to trigger the next event."
