OBSOLETE, adj. No longer used by the timid. Said chiefly of words. A word which some lexicographer has marked obsolete is ever thereafter an object of dread and loathing to the fool writer, but if it is a good word and has no exact modern equivalent equally good, it is good enough for the good writer. Indeed, a writer's attitude toward 'obsolete' words is as true a measure of his literary ability as anything except the character of his work. A dictionary of obsolete and obsolescent words would not only be singularly rich in strong and sweet parts of speech; it would add large possessions to the vocabulary of every competent writer who might not happen to be a competent reader.

Every day it’s something worse being predicted. Mearth says that sooner or later copyright on books will be all in the past because they’ll all be available electronically.

There's no reason that anything should ever become obsolete, whether it be VHS tapes, celluloid film, print books or even the previous versions of a computer operating system, as long as even just one person still wants them around.

The shortcomings of economics are not original error but uncorrected obsolescence. The obsolescence has occurred because what is convenient has become sacrosanct.
