There is a meme currently making its rounds on the Internet that technological progress is slowing down, and even more, that we may be retrograding. For instance, award-winning sci-fi writer Neal Stephenson says this:
“My lifespan encompasses the era when the United States of America was capable of launching human beings into space. Some of my earliest memories are of sitting on a braided rug before a hulking black-and-white television, watching the early Gemini missions. This summer, at the age of 51—not even old—I watched on a flatscreen as the last Space Shuttle lifted off the pad. I have followed the dwindling of the space program with sadness, even bitterness. Where’s my donut-shaped space station? Where’s my ticket to Mars?...
Still, I worry that our inability to match the achievements of the 1960s space program might be symptomatic of a general failure of our society to get big things done. My parents and grandparents witnessed the creation of the airplane, the automobile, nuclear energy, and the computer to name only a few. Scientists and engineers who came of age during the first half of the 20th century could look forward to building things that would solve age-old problems, transform the landscape, build the economy, and provide jobs for the burgeoning middle class that was the basis for our stable democracy.”
Peter Thiel, the founding CEO of PayPal, echoes these sentiments:
“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.”
“One cannot in good conscience encourage an undergraduate in 2011 to study nuclear engineering as a career. ... Without dramatic breakthroughs, the alternative to more-expensive oil may turn out to be not cleaner and much-more-expensive wind, algae, or solar, but rather less-expensive and dirtier coal.”
Both Stephenson and Thiel make interesting points and the reader is well advised to read both articles all the way through.
They are undoubtedly right in that overregulation and NIMBYism (Not In My back Yard) are choking off progress. For instance, the failure of the ramshackled 60’s era Fukashima reactor is taken as an excuse to block the construction of state-of-the-art reactors around the world. For a second – and even more spectacular - example, consider Project Orion, the most ambition realistic program to explore the solar system that was being developed in the 60’s, and which was killed off because it was waaay to politically incorrect. Their slogan was, “Mars by 65, Saturn by 70.” That’s 1965 and 1970.
Another thing retarding progress is today’s extreme risk aversion. As Theil correctly points out, the past was an unbelievably reckless place. To keep moving ahead, we need to regain some of our forefathers’ élan. Space writer Rand Simberg recently pointed out that space cannot be developed without filling entire graveyards with astronauts – people who are our best and brightest. In speeches, America’s leaders are always pointing out the riskiness of space exploration, but judging by the paralysis every Shuttle mishap induces in NASA, I don’t think they really believe it.
And the fact that physicists, mathematicians and engineers can earn more as quants on Wall Street then they can in science and technology is a disturbing indicator of society’s misplaced priorities. But then again, one of the advantages of economic downturns like the crash of 2008 is that it tends to right misplaced priorities.
On the other hand Stephenson and Theil are too pessimistic about progress for a number of reasons:
First of all, a huge amount of scientific and technical progress is happening right now. Theil lamented that since the War on Cancer was declared in the 1970’s, the cure for cancer “remains elusive and appears much farther away.” Excuse me, but this is flat out wrong. While it undoubtedly remains true that modern medicine cannot cure every single cancer patient it sees, it is also true that the cure rate for cancer is much higher now than it was in the 1970’s and is climbing every year. Cancer treatments in the 1970’s were barbaric compared to now. Medicine, in general, is developing very fast. In 2005, an anesthesiologist told me that every drug he administers and every piece of equipment that he uses – everything! – has changed since he graduated medical school in 1985. That’s fast. With the cracking of the DNA code, there is no reason not to believe that the 21st century won’t be the Century of Biotech. In my own field of study (which is not medicine or biology), I have witnessed a complete transformation since I started work in it 23 years ago.
The second is that much of what they are wistful over were big government projects. Things like Apollo and the Manhattan Project have produced spectacular results but the problem with them is that they are not in tune with the rest of our technological state. Rand Simberg once said, the problem with Apollo is that it took something that should have come about in the mid-21st century and placed it into the mid-20th century. There is a time for everything and if you are too far ahead, your creation remains underutilized because we can’t employ it economically. We never went back to the moon because practicality was never a consideration when Apollo was developed.
And third, science and technology don’t advance in a straight line. One of the metrics used by people who believe progress has stalled is the maximum speed achieved by humans. From 1850 until 1970, the maximum speed of humans soared - from steam engines to the Saturn V. But since the 1970’s, it has actually gone backwards (with the end of Apollo and the retirements of the SR-71 and the Concorde). This is true, but it doesn’t paint the whole picture. The reason our ability to move quickly increased so much when it did was because that was the time period when we learned how to harness a new form of chemical energy (basically oil). The reason the top speed in so many different forms of transportation have stalled since then is that we haven’t found a new form of energy to replace oil. Project Orion aside, this won’t happen until a new form of energy is discovered and harnessed. But utilizing energy is just one aspect of technology. Harnessing information and the self-generating complexity of biology are just as legitimate, as far as technological advancements go. What has happened is that we are taking a breather in one branch of technology while advancing along other branches, branches that show more practical potential at present. As I said, the forward path of science is crooked.
Could we be moving ahead faster? Absolutely. I am glad that Stephenson and Thiel are shining a light on the ideal of scientific progress. We need more scientists, engineers and technologists and fewer lawyers, regulators and speculators. But we should also maintain our perspective.
