It has been 40 years since the last astronauts left the moon. That anniversary, which passed last week, has put some prominent technologists in a funk.
"You promised me Mars colonies. Instead, I got Facebook," reads the cover of MIT Technology Review. In an essay titled "Why We Can't Solve Big Problems", editor Jason Pontin considers "why there are no disruptive innovations" today.
Technology Review's headline, running below the face of Apollo astronaut Buzz Aldrin, now 82, is a play on another slogan: "We wanted flying cars. Instead we got 140 characters." That one comes from the manifesto of Founders Fund, a Silicon Valley venture-capital firm started by PayPal founders Peter Thiel, Luke Nosek and Ken Howery to invest in "transformational technologies and companies". (Among their investments is Space X, the launch-system business founded by Elon Musk.)
In speeches, interviews and articles, Thiel decries what he sees as the country's lack of significant innovations. "When tracked against the admittedly lofty hopes of the 1950s and 1960s, technological progress has fallen short in many domains," he wrote last year in National Review. "Consider the most literal instance of non-acceleration: We are no longer moving faster."
Such warnings serve a useful purpose. Political barriers have made it harder to innovate with atoms than with bits. New technologies as diverse as hydraulic fracturing and direct-to-consumer genetic testing (neither mentioned by Thiel) attract instant and predictable opposition. As Thiel writes, "Progress is neither automatic nor mechanistic; it is rare."
But the current funk says less about economic or technological reality than it does about the power of a certain 20th-century technological glamour: all those images of space flight, elevated highways and flying cars, with their promise of escape from mundane existence into a better, more exciting place called The Future.
These visions imprinted themselves so vividly on the public's consciousness that they left some of the smartest, most technologically savvy denizens of the 21st century blind to much of the progress we actually enjoy.
"The future that people in the 1960s hoped to see is still the future we're waiting for today, half a century later," writes Founders Fund partner Bruce Gibney in the firm's manifesto. "Instead of Captain Kirk and the USS Enterprise, we got the Priceline Negotiator and a cheap flight to Cabo."
He forgets just how exotic airplane travel was for the typical TV viewer in 1966, when Star Trek debuted. Today's cheap and easily booked flights let a lot more people fly. That means the average speed at which someone travels over a lifetime can increase even if, as Thiel laments, the fastest vehicle on the planet is no faster than it was decades ago. Making an impressive technology widely available isn't as glamorous as pushing the technological frontier, but it represents significant, real-life progress.
The world we live in would be wondrous to mid-20th-century Americans. It just isn't wondrous to us. One reason is that we long ago ceased to notice some of the most unexpected innovations.
Forget the big, obvious things like internet search, GPS, smartphones or molecularly targeted cancer treatments. Compared with the real 21st century, old projections of The Future offered a paucity of fundamentally new technologies.
They included no laparoscopic surgery or effective acne treatments or ADHD medications or Lasik or lithotripsy - to name just a few medical advances that don't significantly affect life expectancy. The glamorous future included no digital photography or stereo speakers tiny enough to fit in your ears. No forensic DNA testing or home pregnancy tests.
The point isn't that people in the past failed to predict all these innovations. It's that people in the present take them for granted.
