"In retrospect, the research organization which emerged from the decade following the Bell System’s breakup deployed a far richer set of capabilities than its predecessor. In particular, our work featured a growing software component, even as we strove to improve our hardware capabilities in areas such as light-wave and electronics. The marketplace upheaval brought forth by increased competition helped speed the pace of technological revolution, and forced change upon the research and development institutions of all industrialized nations, Bell Labs included. While change is rarely comfortable, I am happy to say that we not only survived but also grew more capable in the process — seeding much of the information revolution which now pervades the world in which we live. Except for two or three papers on interstellar isotopes, my tenure as Bell Labs’ Vice-President of Research brought my personal research in astrophysics to an end. In its place, I pursued my interest in the principles which underlie the creation and effective use of technology in our society, and eventually found time to write a book on the subject Ideas and Information, published by W.W. Norton in 1989. In essence, the book depicts computers as a wonderful tool for human beings but a dreadful role model for what we humans know as intelligence. In other words, “If you don’t want to be replaced by a machine, don’t try to act like one!”"
