Gabriel Zaid introduces Socrates' criticism of books in So Many Books:

Thanks to books, we know that Socrates distrusted books... Conversation depends on those who take part in it... In contrast, books are unfeeling monologues... In sum, intelligence, experience, and the creative life develop and are propagated through live speech, not dead letters.

Zaid argues against this push back on technological progress:

Intelligent conversations like those engaged in by Socrates and Phaedrus, who meet on the street, begin discussing a clever passage by Lycias on love, and go for a walk outside of Athens to debate its meaning, are only possible in an underdeveloped world, where productivity is low and there is plenty of free time. In the modern world, with everyone traveling by car, and leaving just enough time to get where they are going, Socrates and Phaedrus would never meet.

...[W]e no longer have the leisure of free afternoons in Athens. And the simulacrum of inspired life that exists in the great books seems more than a simulacrum: it seems like life, like latent inspiration waiting to be reclaimed. The dead text of Plato's Dialogues preserves the germ of [Socrates'] contagious freedom...

In his sign off to Socrates back in time, Zaid writes:

[I]n making us doubt the progress represented by writing, your criticisms have helped us to identify the true role of books, which is to continue our conversation by other means.
