Maybe. I'm of two minds. Valuable things stand the test of time, they get retold and reused and remembered and kept alive. It's always been like that. On the other hand this could be construed as a defense of oral tradition above writing, but writing has had immense impact on our capabilities and technological progress historically, including the preservation of ancient texts. But I'm not sure we'd be so much better off if we had access to all the gossip news of the time of Plato. Not to mention that forgetting, retelling, rediscovering, discussing stuff anew allows for a kind of evolution and mutation that can regularize and robustify the knowledge.

So we need some preservation, but indiscriminate blind hoarding of all info isn't necessarily the best.
