" The past folds accordion-like into the present. Different media have different event horizons—for the written word, three millennia; for recorded sound, a century and a half—and within their time frames the old becomes as accessible as the new. Yellowed newspapers come back to life. Under headings of 50 Years Ago and 100 Years Ago, veteran publications recycle their archives: recipes, card-play techniques, science, gossip, once out of print and now ready for use. Record companies rummage through their attics to release, or re-release, every scrap of music, rarities, B-sides, and bootlegs. For a certain time, collectors, scholars, or fans possessed their books and their records. There was a line between what they had and what they did not. For some, the music they owned (or the books, or the videos) became part of who they were. That line fades away. Most of Sophocles' plays are lost, but those that survive are available at the touch of a button. Most of Bach's music was unknown to Beethoven; we have it all—partitas, cantatas, and ringtones. It comes to us instantly, or at light speed. It is a symptom of omniscience. It is what the critic Alex Ross calls the Infinite Playlist, and he sees how mixed is the blessing: "anxiety in place of fulfillment, and addictive cycle of craving and malaise. No sooner has one experience begun than the thought of what else is out there intrudes." The embarrassment of riches. Another reminder that information is not knowledge, and knowledge is not wisdom.
