Everything relies on quantum effects. Water wouldn't behave like water. Gold metal would have a different color, etc.

All the same, I don't think there is special quantum magic above and beyond the "ordinary" quantum phenomena needed to explain our brains.

Well quantum computers definitely have "quantum magic"; for some reason the universe lets us build something that can do Shor's algorithm in less than forever. Even if we can't actually do it yet.

But it doesn't seem like human brains are doing Shor's algorithm.
