This text explores the likely impact of the computer in driving a fundamental transformation of our civilization more far-reaching than earlier information revolutions, such as writing and the rise of the early city-states and printing and the Renaissance. The book presents insights and makes predictions of possible future developments in mathematics, science, business, education, the arts and everyday life. While many of the specific predictions may prove to be wrong, the author's perspectives are grounded in current technological capabilities, and while unprecedented changes are predicted, the predictions are couched within a scientifically conservative sensibility.
