Perimeter Institute's Robert Spekkens on quantum foundations. His 2004 classical toy theory makes maximum knowledge always incomplete, and out pops no-cloning, teleportation, and interference Feynman deemed impossible classically. He likens our situation to hieroglyphs before Champollion: a category mistake treating quantum states as describing reality when they describe knowledge of it.
