The book presents the Sumerian language as the firmware programming language for the brainstem, which is supposedly functioning as the BIOS for the human brain. According to characters in the book, the goddess Asherah is the personification of a linguistic virus, similar to a computer virus. The god Enki created a counter-program which he called a nam-shub that caused all of humanity to speak different languages as a protection against Asherah (a re-interpretation of the ancient Near Eastern story of the Tower of Babel).
