Futurist and inventor Ray Kurzweil predicts humans are going
to develop emotions and characteristics of higher complexity as
a result of connecting their brains to computers.
“We’re going to be funnier. We’re going to be sexier. We’re
going to be better at expressing loving sentiment,” Kurzweil
said at a recent discussion at
Singularity University. He is involved in developing
artificial intelligence as a director of engineering at Google
but was not speaking on behalf of the company.
Kurzweil predicts that in the 2030s, human brains will be
able to connect to the cloud, allowing us to send emails and
photos directly to the brain and to back up our thoughts and
memories. This will be possible, he says, via nanobots — tiny
robots from DNA strands — swimming around in the capillaries of
our brain. He sees the extension of our brain into predominantly
nonbiological thinking as the next step in the evolution of
humans — just as learning to use tools was for our ancestors.
And this extension, he says, will enhance not just our
logical intelligence but also our emotional intelligence. “We’re
going to add more levels to the hierarchy of brain modules and
create deeper levels of expression,” he said. To demonstrate, he
gave a hypothetical scenario with Google co-founder Larry Page.
* “So I’m walking along, and I see Larry Page coming, and I
think, ‘I better think of something clever to say.’ But my 300
million modules in my neocortex isn’t going to cut it. I need a
billion in two seconds. I’ll be able to access that in the cloud
— just like I can multiply intelligence with my smartphone
thousands fold today.”
In addition to making us cleverer in hallways, connecting our
brains to the Internet will also make each of us more unique, he
said.
* “Right now, we all have a very similar architecture to our
thinking,” Kurzweil said. “When we can expand it without the
limitations of a fixed enclosure” — he pointed to his head — “we
we can actually become more different.”
“People will be able to very deeply explore some particular
type of music in far greater degree than we can today. It’ll
lead to far greater individuality, not less.”
This view is in stark contrast to a common perception, often
portrayed in science fiction, that cyborg technologies make us
more robotic, less emotional and less human. This concern is
expressed by Dr. Miguel Nicolelis, head of neuroengineering at
Duke University, who fears that if we rely too much on machines,
we’ll lose diversity in human behavior because computers operate
in black and white — ones and zeros — without diversion.
We’re going to expand the brain’s neocortex and become more godlike.
But Kurzweil believes that being connected to computers will
make us more human, more unique and even godlike.
“Evolution creates structures and patterns that over time are
more complicated, more knowledgable, more creative, more capable
of expressing higher sentiments, like being loving,” he said.
“It’s moving in the direction of qualities that God is described
as having without limit.”
“So as we evolve, we become closer to God. Evolution is a
spiritual process. There is beauty and love and creativity and
intelligence in the world — it all comes from the neocortex. So
we’re going to expand the brain’s neocortex and become more
godlike.”
But will brain nanobots actually move out of science fiction
and into reality, or are they doomed to the fate of flying cars?
Like Kurzweil, Nicholas Negroponte, founder of the MIT Media
Lab, thinks that
nanobots in our brains could be the future of learning,
allowing us, for example, to load the French language into the
bloodstream of our brains. James Friend, a professor of
mechanical engineering at UC San Diego focused on medical
nanotechnology, thinks that we’re only two to five years away
from being able to effectively use brain nanobots, for example
to prevent epileptic seizures.
However, getting approval from the U.S. Food and Drug
Administration would likely be very difficult, Friend told The
WorldPost. He thinks approval would take “anywhere from only a
few years to never happening because of people being concerned
about swimming mysterious things into your head and leaving them
there,” he said.
Other scientists are skeptical that brain nanobots will be
safe and effective anytime soon or at all, largely due to
how little we currently understand about how the brain
works. One such scientist is David Linden, professor of
neuroscience at Johns Hopkins University School of Medicine, who
thinks the timing of Kurzweil’s estimation that nanobots will be
in our brains in the 2030s is premature. Linden says there are
huge obstacles, such as adding a nanobot power source,
evading cells that attack foreign bodies and avoiding harming
the proteins and sugars in the tiny spaces between brain cells.
Although the science is far from application in brains,
nanotechnology has long been heralded as a potential game
changer in medicine, and the research is advancing. Last year,
researchers injected into living cockroaches DNA
nanobots that were able to follow specific instructions,
including dispensing drugs, and this year, nanobots were
injected into the
stomach lining of mice.
And we are learning how to enhance our brains, albeit not
with nanobots. Researchers have already successfully sent a
message
from one human brain to another, by stimulating the brains
from the outside using electromagnetic induction. In another
study, similar brain stimulation made people
learn math faster. And in a recent U.S. government study, a
few dozen people who were given brain implants that delivered
targeted shocks to their brain
scored better on memory tests.
We’re already implanting
thousands of humans with brain chips, such as Parkinson’s
patients who have a brain chip that enables better motor control
and deaf people who have a cochlear implant, which enables
hearing. But when it comes to enhancing brains without
disabilities and for nonmedical purposes,
ethical and
safety concerns arise. And according to a survey last year,
72 percent of Americans are
not interested in a brain implant that could improve memory
or mental capacity.
Yet, some believe enhancement of healthy brains is
inevitable, including Christof Koch, chief scientific officer of
the Allen Institute for Brain Science, and Gary Marcus,
professor of psychology at New York University. They use the
analogy of breast implants — breast surgery was developed
for post-mastectomy reconstruction and correcting congenital
defects but has since become popular for breast augmentation.
Brain implants could follow the same path, they say.
Here are Kurzweil’s answers to a couple of the questions he
took at the Singularity University discussion:
You have predicted that in 2029, we will reach the
singularity — the point at which artificial intelligence
outpaces human intelligence. Your opening remarks suggest that
you’re fundamentally positive about AI in the post-2029 world.
Other speakers have been a little more ambivalent, certainly
regarding the future of employment. Would you elaborate on your
overall sentiment on the post-2029 world?
I’ve actually written about the dangers of AI more than most.
But I’m also optimistic, having looked at the positive impact
that technology has had on human life.
When it comes to the existential threat of AI, the primary
strategy comes from governance and social systems. We will have
conflict between different groups of humans, each enhanced by
AI. We have that today with humans using intelligent weapons.
The best tool we have to combat that is to continue to work on
our democracy, liberty and respect for each other.
When it comes to potential unemployment caused by AI, it’s
always been the case that we can clearly see the jobs that are
going away. This started 200 years ago in the
textile industry in England. The weavers, who had enjoyed a
business model passed down for centuries, were suddenly losing
their jobs to machines that could spin thread or weave cloth.
You could look at almost every job, and it would not be long
before it’d be automated. The reality is that employment went
up, and prosperity went up. The common man or woman, rather than
just having one shirt, could now have a whole wardrobe. Life
became better, and there were actually more jobs.
We’re destroying jobs at the bottom of the skill ladder and
creating new jobs at the top. We’ve invested more in education
in the U.S. over the last century. We’ve increased per capita
investment in K-12 education
significantly. We had
50,000 college students in 1870; we have today.
It’s a difficult political situation because people can see
the jobs that are going away, and that’s painful. You say, “Well
but there will be new jobs,” and people say, “What new jobs?”
And you say, “Well, I don’t know; they haven’t been invented
yet.” It’s kind of a weak argument. But it’s true.
We’re also creating jobs that move up Maslow’s hierarchy so
we can spend more time doing things that give us gratification.
People a century ago for the most part were happy if they could
have a job and provide for their family. Today, to an increasing
degree, people get gratification from what they’re doing. They
look for a career that meets their passion — lots of people are
pursuing entrepreneurial ideas. We have 20 million college
students and an equal amount of people who teach them and
support that infrastructure, all to think about knowledge and
organize knowledge. That’s not something people spent much time
doing a century or two ago — we’re going to keep moving in that
direction.
In the 2030s, we will be able to send nanobots into living people’s brains and extract memories of people who have passed away.
Most things are becoming information technology, including
clothing, which will be printed on 3-D printers. We’ll be able
to grow food in vertical agriculture and print it on 3-D
printers, which are pennies for pounds. In the 2020s, 3-D
printing designs will be open source and free so you can live
extremely well and print out everything you need, including
printing out houses.
People say, “Great, there goes all these industries, like
fashion and construction.” But look at industries that have
already gone from physical products to digital products, like
music, movies and books. There’s an open source market with
millions of free products but people still spend money to read
Harry Potter, see the latest blockbuster and buy music from
their favorite artist. Fueled by the ease of distribution and
promotion, you have a coexistence of a free open-source market
and a proprietary market. That’s the direction we’re moving in.
I can’t actually describe exactly what the new jobs will be
but they will be more gratifying. We are already redefining the
nature of work. I don’t feel like I’m working when I go to
Google because I’m doing what I’m passionate about. A lot of
people today don’t like their jobs. So why are people so upset
if these jobs go away? We’ve created a society where you need a
job to have a livelihood. But that’s going to be redefined.
We’re going to have the means of providing an extremely high
standard of living to everyone easily within 15 to 20 years.
In the documentary about yourself, you are preparing yourself
to transcend your death. How do you explain your theory of
immortality?
In the film “Transcendent Man,” I talk about bringing back my
father, Frederick Kurzweil. I’m writing a book now called The
Singularity Is Nearer, and I’m talking about this concept of a
replicant, where we bring back someone who has passed away.
It’ll go through several different stages. First, we’ll create
an avatar based on emails, text messages, letters, video, audio
and memories of the person. Let’s say in 2025, it’ll be somewhat
realistic but not really the same. But some people do actually
have an interest in bringing back an unrealistic replicant of
someone they loved.
By the 2030s, the AIs will be able to create avatars that
will seem very close to a human who actually lived. We can take
into consideration their DNA. In the 2030s, we will be able to
send nanobots into living people’s brains and extract memories
of people who have passed away. Then you can really make them
very realistic.
I have collected and keep many boxes of information about my
father. I have his letters, music, 8mm movies and my fading
memories of him. It will be possible to create a very realistic
avatar in a virtual environment or augmented reality. When you
actually interact with an avatar physically, it will ultimately
pass a Frederick Kurzweil Turing test ― meaning he’ll be
indistinguishable from our memories of the actual Frederick
Kurzweil.
