2A new wave of Technopessimism is upon us.
- They are, on the whole, serious scholars and
sources - Jan Vijg, a Dutch-born molecular biologist in his
The American Technological Challenge Stagnation
and Decline in the 21st Century - Tyler Cowen in his The Great Stagnation
- My esteemed colleague Robert J. Gordon in his
Is U.S. Economic Growth over? Faltering
Innovation confronts the six Headwinds. NBER
Working paper series, 18315 (Aug. 2012). - The Economist (Jan. 12 issue).
3Innovation pessimismHas the ideas machine broken
down?
4There are three brands of techno-pessimism
- One school says, if not quite that everything
that can be invented has been invented, but at
least that the low-hanging fruits have been
picked and the rest of the new inventions wont
have nearly as radical a welfare effect.
5- Another school says that, au contraire, there are
lots of things we still can invent, but we wont.
- This is because we are getting too risk-averse,
too complacent, too regulated, and our
institutions are turning anti-innovative and
sclerotic. - So, much like ancient Rome and Qing China, we are
a once-dynamic world in decline.
6- And finally there are those who think that the
new brave technology actually will come, but that
it will eliminate our jobs and turn us into a
Player Piano kind of dystopia in which all labor
is replaced by machines and robots and humans
will become marginalized.
7Let me first deal with the Gordon-Cowen argument
- They are NOT alone. Many feel disappointed. Peter
Thiel has famously remarked we wanted flying
cars, instead we got 140 characters. - To which I would reply wait till you need a hip
replacement, buddy. - The Economist sided (cautiously) with the
optimists, but it did so (mostly) for the wrong
reasons.
8Is the world running out of ideas?
- Perhaps the low-hanging fruits have been picked
running water, chlorination, electricity, etc? - But science and technologys main function in
history is to make taller and taller ladders to
get to the higher-hanging fruits. They are just
as juicy. - Moreover, these trees keep sprouting new fruits,
if only we give them proper care.
9- Economic Historians should not make predictions.
- That said, from a purely technological point of
view, I would expect the rate of technological
change to accelerate over the next decades, even
if it would be foolhardy to be more specific than
that. -
10Why is this?
- Because of the particular dynamic of useful
knowledge

11Historians of technology have pointed out that
the two mutually affect one another in complex
ways.
- Derek Price and Nathan Rosenberg have noted that
technology affects science as much as the other
way around. It did so through what Price called
artificial revelation. - Science depends on technology no less than
technology on science we were not hard-wired to
see microbes, to watch the moons of Jupiter, to
store terabytes of information in our brains and
do 54 petaflops of calculations tools and
machines we build do this for us.
12Throughout modern history, the tools and
instruments devised to do science have
determined how fast science would advance.
- The best-known examples are of course the
telescope and microscope, but there are many
others. Let me give you a few lesser-known
examples from the era before and during the
Industrial Revolution to drive the point home.
13Robert Boyles famous airpump, built in the late
1650s, which showed once and for all that contra
Aristotle, nature did not abhor a vacuum, and
thus paved the road for atmospheric (steam)
engines.

15Laplaces calorimeter
Calorimeter first used in the winter of 1782-83,
by Antoine Lavoisier and Pierre-Simon Laplace, to
determine the heat evolved in various chemical
changes calculations which were based on Joseph
Blacks prior discovery of latent heat.

17Another example Alessandro Volta, 1745-1827
18Voltas battery provided chemists with a new
tool, electrolysis, pioneered by Humphry Davy. He
and other chemists were able to isolate element
after element, and fill in much of the detail in
the maps whose rough contours had been sketched
by Lavoisier and Dalton.
19In our own age, technology has continued this
trend in spades.
- Scientists have arsenals of tools that we could
not have dreamed of even a few decades ago,
measuring, observing, calculating, modelling,
creating laboratory experiments in physics,
microbiology, and nanochemistry that nobody
thought off a few decades ago, let alone in 1800. - Here is one example that I just heard about this
summer
20Adaptive optics
21- These are two images of the planet Uranus, one
using an ordinary telescope, the other one in
which the blurring caused by atmospheric
distortions are corrected. - Adaptive optics technology sharpens images by
changing the shape of telescope mirrors up to
1,000 times per second. - It is believed to have more potential than
Hubbles telescope (and a lot less expensive).
22Another example how technology helps science
Automatic Gene sequencing machine, first
developed at CalTech in 1986 by Dr. Leroy Hoods
laboratory.
23A last example synchotron
- A synchrotron is a stadium-sized machine that
produces many beams of bright X-ray light. - Synchrotrons provide flexible, powerful methods
for learning about the structure and behavior of
matter at the molecular and atomic level. -

24The significance of ever-growing artificial
revelation
- The implication is simple if the positive
feedback loop between technology and science is
getting stronger all the time, science will
continue to expand at ever faster rates, and it
is plausible that technology itself will do the
same, even if we cannot tell in which directions
and how fast . - It is hard to see this dynamic system ever
settling down on an equilibrium.
25My second reason for being a techno-optimist is
similar but not quite the same
- Here is a simple argument
- What is the total social useful knowledge that an
economy has access to? - Answer it is the union of all individual sets of
useful knowledge. - Corollary some very important pieces of
knowledge are only possessed by very few
extraordinarily smart individuals (most of them
at CalTech).
26This does not matter as long as those who need
this knowledge have access to it.
- But access can be costly. What determines access
costs? - Among many factors, clearly the cost of storing
information and searching through it figure
highly. - In the past, the most important advances in
search-engine technology were these

dynasty era (c 1400)
28Printing Press and moveable type, invented by Pi
Sheng ( 1st half,11th c.)
29- But knowledge needs to be organized if access is
to be fast and cheap.

31If there is anything where we have made progress
in the past two decades, it is access technology.
- We no longer deal with data ? we have
meta-data, amazing quantities of information
that can only be accessed with sophisticated
searchware. We can search for extremely small
needles in gargantuan haystacks. - This has political and commercial applications
that have been discussed in recent weeks ad
nauseam. - But it has also enormous implications for further
technological advances.
32Access matters
- First, any inventor must be sure she is not
re-inventing the wheel and that nobody else has
already done this. - Second, many inventions are recombinations and
analogues of existing technological components
and devices. Again, finding out easily and
cheaply what is out there makes the process
easier. - Third, despite what some people believe, a lot of
technological progress still depends on trying
every bottle on the shelf. Modern storage and
access creates very large shelves and many
bottles (think petabottles).
33- Anyone engaged in research can access vast banks
of knowledge and data. Cloud technology is just
getting started. We measure storage now not in
megabytes but Zettabytes (a million petabytes)
and Yottabytes (1000 Zettabytes) (WHO makes up
those terms? --- there is also Brontobytes). - We can also consult experts half a globe away in
the blink of an eye through email, facebook,
skype and what not. - So access costs have declined sharply for both
codifiable and tacit knowledge.
34- Fourth, technology normally advances best if it
can rely on the results of best-practice science,
both to know what works and (equally importantly,
what does not).
35So if everything is so good, why is everything
so bad?
- Answer it is not.
- Its just that in technology the results often
are unexpected and take forms that are not easily
measured by the criteria and measures of the
technological ancient regime. - Imagine an Englishman at a party celebrating the
50th anniversary of the first steam engine. - That would be in 1762.
- He would ask What has that machine done for us?
Made a lot of noise, emitted a lot of smoke and
stench, and pumped some water out of a few coal
mines. Big Deal.
Technopessimism

36- We dont know what the adoption lags are today,
probably less than then, but the really BIG
results usually arrive toward the end when the
technology is fully mature. - Most of the disruptive and life-changing effects
of digitalization have not been fully felt. - The Digital Age will be to the Analog Age what
the iron age was to the stone age. - And we cant even imagine what the Post-digital
Age will look like. No more than Archimedes could
imagine CERN.

38- Today we measure progress by measures such as GDP
and its derivative, TFP. These were designed for
steel-and-wheat economies. - The digital age, largely based on a service
economy, needs other measures, that are far more
sensitive to the constant appearance of new goods
and services, incessant improvement in their
quality and capabilities.
39- But given the ever-more rapid development of
access technology and better scientific
instruments, it seems hard to somehow avoid the
conclusion that we are in for an ever-lasting
rate of technological progress.
40Is this the good news or the bad news?
- Here is Mokyrs theorem Technological progress
is never Pareto superior. There are always
losers. And we rarely compensate them. - I am not the first to argue this Schumpeter
spoke of creative destruction. - So there will be losers. What we gain as
consumers, viewers, patients, and citizens, we
may lose as workers.
41What will the workplace of the future be like?
- Here are three things to keep in mind
- First, the factory, which arose in the
Industrial Revolution is slowly being phased out.
We will work, wherever, whenever it suits us.
Workplace and commuting will slowly disappear.
Three-dimensional printers will make whatever
assembly line shopfloor workers were making. - Well miss the water cooler human interaction,
but there is always social networks.
42- Second, robotics will be everywhere. These Robots
will not be anything like the iron humanoids that
follow the Asimov rules of robotics. Most of them
will be nothing more than little chips connected
by A.I. to sensors. But they will drive our
trucks, perform open-heart surgeries, pick our
tomatoes, walk our dogs, and cook our meals. - But only if we want them to. That, by
definition, is a welfare improvement.
43So, what will WE do?
- Third, the post-digital age may be the Age of
Leisure. - Remember that practically the entire leisure
industry, from videogames to spectator sports, to
radio, tv, movies was a product of the twentieth
century. Thats because the workweek (in Europe)
fell from 3,000 hrs a year to 1,500 hrs. - If robots do all the production, there will be
far more leisure. - Will we be bored and feel unproductive? Some
will, some wont. Just like now
44But remember that historically we have always had
a leisured class
- Roman patricians, Chinese Mandarins, Medieval
knights, Eighteenth-century Russian landlords. - Its just that these were a small minority. They
did things even if they did not have to. - Just like tenured professors doing research. And
their graduate students playing videogames.
