>Text is the oldest and most stable communication technology

That's completely false: Images were used for storytelling thousands of years before text (compare for instance the Lascaux paintings which are more than 17 000 years old, the Göbeklitepe sculptures and stone drawings (more than 12 000 years old), or the the more than 15 000 paintings of the City of Sefar (Algeria) which some estimate to date back as far as 20 000 years ago to the earliest text known in human history, Kish Tablet, Mesopotamia, around 3500 years old.
