The Human Promise of the AI Revolution
Artificial intelligence will radically disrupt the world of
work, but the right policy choices can make it a force for a more
compassionate social contract. By
Kai-Fu Lee
Artificial intelligence is a technology that sparks the human
imagination. What will our future look like as we come to share the
earth with intelligent machines? Our minds gravitate to extremes, to the
sharply contrasting visions that have captured public attention and
divided much of the technological community. As a longtime AI researcher
and venture capitalist in China and the U.S., I’ve observed these
two camps across
continents and over many decades.
Utopians believe that once AI far
surpasses human intelligence, it will provide us with near-magical tools
for alleviating suffering and realizing human potential. In this vision,
super-intelligent AI systems will so deeply understand the universe that
they will act as omnipotent oracles, answering humanity’s most vexing
questions and conjuring brilliant solutions to problems such as disease
and climate change.
But not everyone is so optimistic. The best-known member of the
dystopian camp is the technology
entrepreneur Elon Musk, who has called super-intelligent AI systems “the
biggest risk we face as a civilization,” comparing their creation to
“summoning the demon.” This group warns that when humans create
self-improving AI programs whose intellect dwarfs our own, we will lose
the ability to understand or control them.
Which vision to accept? I’d say neither.
They simply aren’t possible based on the technology we have today or any
breakthroughs that might be around the corner. Both scenarios would
require “artificial general intelligence”—that is, AI systems that can
handle the incredible diversity of tasks done by the human brain. Making
this jump would require several fundamental scientific breakthroughs,
each of which may take many decades, if not centuries. The
real battles that lie ahead will lack the apocalyptic drama of Hollywood
blockbusters, but they will disrupt the structure of our economic and
political systems all the same. Looming before us in the coming decades
is an AI-driven crisis of jobs, inequality and meaning. The new
technology will wipe out a huge portion of work as we’ve known it,
dramatically widening the wealth gap and posing a challenge to the human
dignity of us all. This
unprecedented disruption requires no new scientific breakthroughs in AI,
just the application of existing technology to new problems. It will hit
many white-collar professionals just as hard as it hits blue-collar
factory workers.
Despite these immense challenges, I remain hopeful. If handled with care
and foresight, this AI crisis could present an opportunity for us to
redirect our energy as a society to more human pursuits: to taking care
of each other and our communities. To have any chance of forging that
future, we must first understand the economic gauntlet that we are about
to pass through. Many
techno-optimists and historians would argue that productivity gains from
new technology almost always produce benefits throughout the economy,
creating more jobs and prosperity than before. But not all inventions
are created equal. Some changes replace one kind of labor (the
calculator), and some disrupt a whole industry (the cotton gin). Then
there are technological changes on a grander scale. These don’t merely
affect one task or one industry but drive changes across hundreds of
them. In the past three centuries, we’ve only really seen three such
inventions: the steam engine, electrification and information
technology.
Looking at this smaller data set, we have a mixed bag of economic
impacts. The steam engine and electrification created more jobs than
they destroyed, in part by breaking down the work of one craftsman into
simpler tasks done by dozens of factory workers. But information
technology (and the associated automation of factories) is often cited
by economists as a prime culprit in the loss of U.S. factory jobs and
widening income inequality. The
AI revolution will be of the magnitude of the Industrial Revolution—but
probably larger and definitely faster. Where the steam engine only took
over physical labor, AI can perform both intellectual and physical
labor. And where the Industrial Revolution took centuries to spread
beyond Europe and the U.S., AI applications are already being adopted
simultaneously all across the world.
AI’s main advantage over humans lies in its ability to detect incredibly
subtle patterns within large quantities of data and to learn from them.
While a human mortgage officer will look at only a few relatively crude
measures when deciding whether to grant you a loan (your credit score,
income and age), an AI algorithm will learn from thousands of lesser
variables (what web browser you use, how often you buy groceries, etc.).
Taken alone, the predictive power of each of these is minuscule, but
added together, they yield a far more accurate prediction than the most
discerning people are capable of.
Humanoid robots are getting better at walking, talking and looking like
humans. But as they continue to evolve, will us real humans want to
spend time with them? And exactly how useful could they become? For this
episode of Moving Upstream, WSJ’s Jason Bellini travels to Asia to meet
some of the leaders in the humanoid robotics revolution. For
cognitive tasks, this ability to learn means that computers are no
longer limited to simply carrying out a rote set of instructions written
by humans. Instead, they can continuously learn from new data and
perform better than their human programmers. For physical tasks, robots
are no longer limited to repeating one set of actions (automation) but
instead can chart new paths based on the visual and sensor data they
take in (autonomy).
Together, this allows AI to take over countless tasks across society:
driving a car, diagnosing a disease or providing customer support. AI’s
superhuman performance of these tasks will lead to massive increases in
productivity. According to a June 2017 study by the consulting firm PwC,
AI’s advance will generate $15.7 trillion in additional wealth for the
world by 2030. This is great news for those with access to large amounts
of capital and data. It’s very bad news for anyone who earns their
living doing soon-to-be-replaced jobs.
There are, however, limits to the abilities of today’s AI, and those
limits hint at a hopeful path forward. While AI is great at optimizing
for a highly narrow objective, it is unable to choose its own goals or
to think creatively. And while AI is superhuman in the coldblooded world
of numbers and data, it lacks social skills or empathy—the ability to
make another person feel understood and cared for. Analogously, in the
world of robotics, AI is able to handle many crude tasks like stocking
goods or driving cars, but it lacks the delicate dexterity needed to
care for an elderly person or infant. What
does that mean for workers who fear being replaced? Jobs that are
asocial and repetitive, such as fast-food preparers or insurance
adjusters, are likely to be taken over in their entirety. For jobs that
are repetitive but social, such as bartenders and doctors, many of the
core tasks will be done by AI, but there remains an interactive
component that people will continue to perform. The jobs that will be
safe, at least for now, are those well beyond the reach of AI’s
capabilities in terms of creativity, strategy and sociability, from
social workers to CEOs. Even
where AI doesn’t destroy jobs outright, however, it will exacerbate
inequality. AI is inherently monopolistic: A company with more data and
better algorithms will gain ever more users and data. This
self-reinforcing cycle will lead to winner-take-all markets, with one
company making massive profits while its rivals languish. A
similar consolidation will occur across professions. The jobs that will
remain relatively insulated from AI fall on opposite ends of the income
spectrum. CEOs, home care nurses, attorneys and hairstylists are all in
“safe” professions, but the people in some of these professions will be
swimming in the riches of the AI revolution while others compete against
a vast pool of desperate fellow workers. We
can’t know the precise shape and speed of AI’s impact on jobs, but the
broader picture is clear. This will not be the normal churn of
capitalism’s creative destruction, a process that inevitably arrives at
a new equilibrium of more jobs, higher wages and better quality of life
for all. Many of the free market’s self-correcting mechanisms will break
down in an AI economy. The 21st century may bring a new caste system,
split into a plutocratic AI elite and the powerless struggling masses.
Recent history has shown us just how fragile our political institutions
and social fabric can be in the face of disruptive change. If we allow
AI economics to run their natural course, the geopolitical tumult of
recent years will look like child’s play. On a
personal and psychological level, the wounds could be even deeper.
Society has trained most of us to tie our personal worth to the pursuit
of work and success. In the coming years, people will watch algorithms
and robots easily outmaneuver them at tasks they’ve spent a lifetime
mastering. I fear that this will lead to a crushing feeling of futility
and obsolescence. At worst, it will lead people to question their own
worth and what it means to be human. So
what can be done? This
grim vision is shared by many technologists in Silicon Valley, and it
has sent them casting about for solutions. As the architects and
profiteers of the AI age, they feel a mix of genuine social
responsibility and fear of being targeted when the pitchforks come out.
In their rush for a quick fix, many of the techno-elite have seized on
the idea of a universal basic income: an unconditional,
government-provided cash stipend to allow every citizen to meet their
basic needs. I
can see the appeal. UBI is exactly what Silicon Valley entrepreneurs
love: an elegant technical solution to tangled social problems. UBI can
be the magic wand that lets them wish away the messy complexities of
human psychology and get back to building the technologies that “make
the world a better place,” while making them rich. It’s an approach that
maps well onto how they tend to view society: as a collection of “users”
rather than as citizens, customers and human beings. We
can do better. Some form of guaranteed income may indeed be necessary,
but if we allow such support to be the endgame, we will miss the
opportunity presented by this transformative technology. Instead of
simply falling back on an economic painkiller like a universal basic
income, we should use the economic bounty generated by AI to double down
on what separates us from machines: human empathy and love. Such
a revolution in how we relate to work will require a rethink from all
corners of society. In the private sector, instead of simply viewing AI
as a means for cost-cutting through automation, businesses can create
new jobs by seeking out symbiosis between AI optimizations and the human
touch. This will be especially powerful in areas such as health care and
education, where AI can produce crucial insights but only humans can
deliver them with care and compassion.
Beyond the private sector, governments across the world need to start
thinking now about how to use the riches generated by AI to rewrite the
social contract and reorient our economies to promoting human
flourishing. At
the center of this vision, I would suggest, there needs to be what I
call the Social Investment Stipend, a respectable government salary for
those who devote their time to three categories of activities: care
work, community service and education. These activities would form the
pillars of a new social contract, rewarding socially beneficial
activities just as we now reward economically productive activities. The
idea is simple: to inject more ambition, pride and dignity into work
focused on enhancing our communities. Care
work could include parenting or home schooling of young children,
assisting aging parents or helping a friend with mental or physical
disabilities live life to the full. Service work would focus on much of
the current work of nonprofit and volunteer groups: leading after-school
programs, guiding tours at parks or collecting oral histories from
elders in our communities. Supported education activities could range
from professional training for the jobs of the AI age to taking classes
that turn a hobby into a career. The
participation requirements of the stipend wouldn’t be designed to
dictate the lives of citizens. There would be a wide enough range of
choices for all workers who have been displaced by AI. The more
people-oriented could opt for care work, the ambitious could enroll in
high-tech training, and others could take up community-service work. By
requiring some social contribution to receive the stipend, we would
foster a public philosophy far different from the laissez-faire
individualism of universal basic income. Providing a stipend in exchange
for participation in community-building activities carries a clear
message: Collective effort from people across society allowed us to
reach this point of economic abundance, and now we must use that
abundance to recommit ourselves to one another and to our humanity. Many
difficult questions remain to be answered, of course, before we could
consider implementing such a sweeping and idealistic policy. The urgency
to create, and the ability to pay for, a far-reaching Social Investment
Stipend will depend on the pace and nature of AI’s economic impact. But
the humanistic values it embodies can serve as a guide while we navigate
the treacherous waters that lie ahead. We may yet be able to harness the
full potential of both machines that think and humans who love.
