Bit has a gigantic toybox — 12,631 toys. But whenever he plays, he only ever grabs about 34 at a time. The other ~12,600 sit in the dark, untouched.
And even those 34 aren't equal: a tiny handful of favorites (the, and, to) come out constantly, while most toys he's touched maybe once ever.
THAT'S the secret to his closet trick. He can angle-pack thousands of toys into a few shelves precisely because he never grabs enough at once to make mush. Language hands him sparsity for free — so superposition just works.
