I wonder, does this account for compression? Are the bits counting a concrete representation of ideas transmitted? Or are bits counting a simple abstraction over syllables, similar to a token? Language is compression. And while humans may transmit at a universal rate, maybe some languages/cultures have a more dense compression of ideas than others? Like in Turkish, how there's a word for "moonlight on the water" https://ihearthesamewinds.wordpress.com/2011/11/01/142/.
