McLuhan quoted Socrates.
Replace “alphabet” with “AI.” Does it sound familiar?
“The discovery of the alphabet will create forgetfulness in the learners’ souls, because they will not use their memories; they will trust to the external written characters and not remember of themselves… You give your disciples not truth but only the semblance of truth; they will be heroes of many things, and will have learned nothing; they will appear to be omniscient and will generally know nothing.” -Socrates, Phaedrus
