At birth, babies can distinguish the phonemes of every language on earth — Czech clicks, Hindi retroflexes, all of it. By 12 months, that ability collapses and they only hear the phonemes of their native tongue. Bloom frames it bluntly: 'When you were a baby you were a multilingual fool. Now, if you're like me, you could barely understand English.' The window for native-level acquisition slams shut around puberty, which is why immigrants who arrive past adolescence almost always carry an accent no matter how smart or motivated they are.
