I don’t know, but this article by Ryan Britt made me think.
Not once in any Star Wars movie does someone pick up a book or newspaper, magazine, literary journal, or chapbook handmade by an aspiring Jawa poet. If something is read by someone in Star Wars, it’s almost certainly off of a screen (and even then, maybe being translated by a droid), and it’s definitely not for entertainment purposes. As early as the 1990s-era expanded Star Wars books and comic books, we’re introduced to ancient Jedi “texts” called holocrons, which are basically talking holographic video recordings. Just how long has the Star Wars universe been reliant on fancy technology to transfer information as opposed to the written word? Is it possible that a good number of people in Star Wars are completely illiterate?
Obi-Wan may have put a lightsaber in Luke’s hand, but really he and Qui-Gon should have been going around teaching people on poor planets to read years and years prior. After all, hokey religions and ancient weapons are no match for a good book in your hands.
