The stars are real. The future is that mountain.
When tracked against the admittedly lofty hopes of the 1950s and 1960s, technological progress has fallen short in many domains. Consider the most literal instance of non-acceleration: We are no longer moving faster. The centuries-long acceleration of travel speeds — from ever-faster sailing ships in the 16th through 18th centuries, to the advent of ever-faster railroads in the 19th century, and ever-faster cars and airplanes in the 20th century — reversed with the decommissioning of the Concorde in 2003, to say nothing of the nightmarish delays caused by strikingly low-tech post-9/11 airport-security systems. Today’s advocates of space jets, lunar vacations, and the manned exploration of the solar system appear to hail from another planet. A faded 1964 Popular Science cover story — “Who’ll Fly You at 2,000 m.p.h.?” — barely recalls the dreams of a bygone age.
The official explanation for the slowdown in travel centers on the high cost of fuel, which points to the much larger failure in energy innovation. (…)
By default, computers have become the single great hope for the technological future. The speedup in information technology contrasts dramatically with the slowdown everywhere else. Moore’s Law, which predicted a doubling of the number of transistors that can be packed onto a computer chip every 18 to 24 months, has remained broadly true for much longer than anyone (including Moore) would have imagined back in 1965. We have moved without rest from mainframes to home computers to the Internet. Cellphones in 2011 contain more computing power than the entire Apollo space program in 1969.
