Hey, thanks so much for that link. I liked Rye's conjectural piece on prehistoric languages (Neanderthal and Cro-Magnon) too. Also his lists of technological predictions from Heinlein and Clarke with commentary (though his constant sniping at Heinlein, with the benefit of 20/20 hindsight, isn't quite fair; I'd like to see Rye try to make accurate predictions of tech progress 50 years from now).
