Odd article written by Lee deForest the inventor of the Audion, a vacuum tube amplifier that ushered in the radio and electronics age. He discusses the origins and growth of electronics and what the future may bring, including dissing the transistor and living room walls that keep one warm by microwaves. He also has some firm opinions regarding the uses to which his invention has been put:

The microphone-amplifier-loudspeaker combination is having an enormous effect on our civilization. Not all of it is good! Consider to what heights of impudence and tyranny, and to what depths of moral depravity, has radio broadcasting and the loudspeaker attained in that recent monstrosity, Transit Radio, Inc. Almost incredible is the loathsome fact that already in 21 cities bus riders must listen to never-ending, blatant advertising and unwelcome jitterbug and bop music, “viciously repugnant to the spiritual and intellectual assumptions of American life,” as Prof. Charles Black of Columbia University wrote. This outrage is unquestionably the all-time low to which radio broadcasting can sink.

Dawn of the Electronic Age
By Lee deForest (“Father of Radio”)

WHEN VOCAL SOUND first became articulate the ancestor of man leaped suddenly from the dumb shackles of the brute. The first crude sign writing, whereby thoughts might be recorded, helped to bring scattered men and tribes into social units and establish contact with future generations through the permanency of the written word. For ages, ecclesiastics maintained a monopoly of reading and writing. Then came movable type and the printing press of Gutenberg. Reading and writing became common heritage. The postal service followed, fostering a moderate exchange of thought between people. Ancient Greeks developed a crude method of heliograph for military signaling. Then flags by day and fires by night conveyed information over wide distances. Later, the system of signaling by semaphore devised by Claude Choppe during the French Revolution blazed the path leading to the electric telegraph of Morse. Scarcely more than a century ago came the first telegraph, an instantaneous means for communicating over great land distances, followed by the submarine cable for spanning the oceans. Bell, experimenting with a new form of telegraphy, came upon the telephone, and as a result business and social life were; immeasurably increased in tempo. Late in the 19th century, wireless telegraphy entered the communications field, first as a means of spinning threads between ships and shores, and robbing the sea of its sinister silence; later as a practical means of transoceanic communication. Inspired by the classical formulas of Maxwell in England, Hertz in Germany in the 1880s discovered electromagnetic waves, proving them akin to light waves but of vastly longer wavelengths and lower frequencies.
