The second transformation? Smart
manufacturing. This is the first structural shift since Henry Ford
launched the economic power of "mass production." While we see evidence
already in automation and information systems applied to supply-chain
management, we are just entering an era where the very fabrication of
physical things is revolutionized by emerging materials science.
Engineers will soon design and build from the molecular level,
optimizing features and even creating new materials, radically improving
quality and reducing waste.
Devices and products are already
appearing based on computationally engineered materials that literally
did not exist a few years ago: novel metal alloys, graphene instead of
silicon transistors (graphene and carbon enable a radically new class of
electronic and structural materials), and meta-materials that possess
properties not possible in nature; e.g., rendering an object
invisible—speculation about which received understandable recent
publicity.
This era of new materials will be economically explosive when
combined with 3-D printing, also known as direct-digital
manufacturing—literally "printing" parts and devices using computational
power, lasers and basic powdered metals and plastics. Already emerging
are printed parts for high-value applications like patient-specific
implants for hip joints or teeth, or lighter and stronger aircraft
parts. Then one day, the Holy Grail: "desktop" printing of entire final
products from wheels to even washing machines.
The era of near-perfect computational design and production will
unleash as big a change in how we make things as the agricultural
revolution did in how we grew things. And it will be defined by high
talent not cheap labor.
Finally, there is the unfolding communications revolution where soon
most humans on the planet will be connected wirelessly. Never before
have a billion people—soon billions more—been able to communicate,
socialize and trade in real time.
The implications of the radical collapse in the cost of wireless
connectivity are as big as those following the dawn of
telegraphy/telephony. Coupled with the cloud, the wireless world
provides cheap connectivity, information and processing power to nearly
everyone, everywhere. This introduces both rapid change—e.g., the Arab
Spring—and great opportunity. Again, both the launch and epicenter of
this technology reside in America.
Few deny that technology fuels economic growth as well as both social
and lifestyle progress, the latter largely seen in health and
environmental metrics. But consider three features that most define
America, and that are essential for unleashing the promises of
technological change: our youthful demographics, dynamic culture and
diverse educational system.
First, demographics. By 2020, America will be younger than both China
and the euro zone, if the latter still exists. Youth brings more than a
base of workers and taxpayers; it brings the ineluctable energy that
propels everything. Amplified and leavened by the experience of their
elders, youth and economic scale (the U.S. is still the world's largest
economy) are not to be underestimated, especially in the context of the
other two great forces: our culture and educational system.
The American culture is particularly suited to times of tumult and
challenge. Culture cannot be changed or copied overnight; it is a
feature of a people that has, to use a physics term, high inertia. Ours
is distinguished by incontrovertibly powerful features, namely
open-mindedness, risk-taking, hard work, playfulness, and, critical for
nascent new ideas, a healthy dose of anti-establishment thinking. Where
else could an Apple or a Steve Jobs have emerged?
Then there's our educational system, often criticized as inadequate
to global challenges. But American higher education eludes simple
statistical measures since its most salient features are flexibility and
diversity of educational philosophies, curricula and the professoriate.
There is a dizzying range of approaches in American universities and
colleges. Good. One size definitely does not fit all for students or the
future.
We should also remember that more than half of the world's top 100
universities remain in America, a fact underscored by soaring foreign
enrollments. Yes, other nations have fine universities, and many more
will emerge over time. But again the epicenter remains here.
What should our politicians do to help usher in this new era of
entrepreneurial growth? Liquid financial markets, sensible tax and
immigration policy, and balanced regulations will allow the next boom to
flourish. But the essential fuel is innovation. The promise resides in
the tectonic technological shifts under way.
America's success isn't preordained. But the technological
innovations circa 2012 are profound. They will engender sweeping changes
to our society and our economy. All the forces are in place. It's just a
matter of when.
