> We have accounts from the ancient Greeks of the old-school's attitude towards writing. In the deep past, they maintained an oral tradition, and scholars were expected to memorize everything. They saw writing/reading as a crutch that was ruining the youth's memory.

Not exactly.

We have accounts from figures who became famous by going against popular opinion, who aired those thoughts. It probably was not the mainstream belief, in that place, at that time. Don't try and judge Ancient Greece by Socrates or Plato - they were celebrities of the controversial.
