Comments from the Preface could easily apply to the modern world of computing: "The opening up of competition has also flooded the market with all kinds and styles of instruments, and those of us who thought we had mastered the art, found out that there was yet a great deal to learn. Besides, competition has now made the public exacting and discriminating, and nothing but the best will do, and the old days of grounded circuits and inefficient instruments are past; but, such is progress."
