Binary text.... for big brains?
21 years later and this still bugs me: Diamond talks about the big brain stuff, but then he reads a paper that is all ones and zeros. That's supposed to look impressive because it's the same as computers read, but using only two options for each text character is the exact opposite of something big brains would do. Heck, us little brains in the West have 36 unique characters, plus punctuation and math symbols. Japanese and Chinese have hundreds of symbols. For big brains to really impress, they should have a text code that contains thousands or even millions of symbols. Some of them could represent entire sentences or paragraphs.
Diamond could have had a few very slim pamphlets in his office called "War and Peace", "Moby Dick", and "Les Miserables" to demonstrate.
