By 2045 the human species will end and human beings will become
human/machine cyborgs - godlike hybrids capable of nearly infinite
intelligence and immortal existence. At least these are the beliefs of
numerous Silicon Valley CEOs who are actively pursuing the fulfillment
of this prophecy through what has been called the "Singularity
Movement." Leaders of the Movement believe that the advances in
computational power, genomics, and medicine will allow them to live
forever in a techno-utopia - if they live long enough to get there.
The players
Vernor Vinge, a science fiction writer, computer scientist, and math
professor, wrote a research paper in 1993 called "The Coming
Technological Singularity: How to Survive in the Post-Human Era," which
kicked off the Singularity Movement. However, the current promoters of
the Singularity Movement reads like a Who's Who of Silicon Valley's
"finest" - Peter Thiel, a former CEO of PayPal, is the advisor for
Singularity Institute for Artificial Intelligence, in San Francisco,
Andrew Hessel, a former research operations manager at Amgen, Sergey
Brin, a co-founder of Google, Larry Page, another Google co-founder, who
helped set up Singularity University in 2008. Google has supported
Singularity University with more than $250,000 in donations.
The primary spokesperson for the singularity movement is Raymond
Kurzweil, a millionaire inventor, who has been trying to sell the idea
to young entrepreneurial types for a number of years. Kurzweil has
written the book, The Singularity Is Near, and gives up to 60 lectures
per year, including his cross-country multimedia road show to promote
Transcendent Man, a documentary about his life and beliefs. Kurzweil is
co-founder of Singularity University, which charges $25,000 for a
10-week course in Singularity philosophy and "science." He takes up to
200 pills and supplements a day, developed a line of health supplements
called Ray & Terry's, along with health books, Fantastic Voyage: Live
Long Enough to Live Forever and Transcend: Nine Steps to Living Well
Forever. He hasn't been shy about stating the reason for his ardor - he
simply wants to live forever. At age 62, Kurzweil's time is rapidly
running out based upon the current rate of "progress."
Computing power
The idea that computers will become intelligent enough to achieve true
artificial intelligence is based upon an exponential rate of increase in
computational power. According to Kurzweil and others, these miniscule
supercomputers will be implanted inside human brains to produce a
human-machine cyborg capable of almost unlimited intelligence. Kurzweil
writes: "Once nonbiological intelligence gets a foothold in the human
brain (this has already started with computerized neural implants), the
machine intelligence in our brains will grow exponentially (as it has
been doing all along), at least doubling in power each year."1 Moore's
law stated that the number of transistors on a chip would double about
every two years. This law has held for the last 40 years. However,
doubling transistors does not result in a doubling of computational
power (expressed as million instructions per second, MIPS).
During the 1980's and 1990's computing power doubled every two years. The assumption was that it would continue to do so indefinitely. A widely publicized graph of computational power was done by Hans Moravec in 2002. The graph is reproduced to the right, with the updated MIPS added for the current year. As can be seen, the latest point has fallen off the exponential 1995 trend, down to the 1985 trend. If computational power had remained exponential, the current value should be ~1 million MIPS per thousand dollars, instead of ~70,000 MIPS/$1000 currently available. My prediction is that it will fall off the 1985 curve to the 1975 curve by the end of this decade.
Why can't computational power
continue to increase exponentially indefinitely? It's called physics. It
is not possible to shrink transistor size less than atomic scale.
According to the Intel website, "Physical limits of atomic structures or
power density could be reached by 2020."2 This means computational power
based upon transistor density will stop increasing altogether by 2020.
The only way to increase computational power after that point (barring
development of some, as of yet undeveloped, technology) will be to make
the devices larger by adding more processors. This may result in linear
increase of computational power, but certainly not exponential, as Kurzweil predicts.
Artificial intelligence
One of the main goals of the Singularity Movement is to produce a
computer that exhibits true artificial intelligence (AI). Deep Blue was
a chess-playing computer developed by IBM in the late 1980s and 1990s.
On May 11, 1997, the machine won a six-game match against world champion
Garry Kasparov. However, Deep Blue was not an example of artificial
intelligence. It was merely good at playing chess, being able to analyze
hundreds of thousands of moves.
In 2011, Watson, another IBM invention, consisting of 90 servers and a massive database was able to beat Jeopardy champions by ranking answers by probability. It was able to understand simple English well, so answered all the straight-forward questions correctly. However, it wasn't as good at complex sentence structure and idioms (although many of those were included in its database. A human can understand even a new idiom based upon some recognizable analogy. Watson cannot do that - just like Lieutenant Commander Data on Star Trek had difficulty with idioms. So, throwing raw processing power and lots of data at the AI problem does not reproduce the human brain. Maybe the main problem is that we have no idea how the human brain stores and retrieves information. Yes, we know that certain areas of the brain are primarily involved, that the process involves generating synapses between neurons, neurotransmitters, and protein synthesis, but exactly how this is done remains a profound mystery.
Memories are not stored within single neurons,3 so the system is in no
way analogous to volatile or non-volatile information storage in
computer systems. Henry Markram of the Brain Mind Institute of the Ecole
Polytechnique in Lausanne, Switzerland, is attempting to create a
neuron-by-neuron simulation of a mammalian brain, using IBM's Blue Gene
super-computer. According to Ray Kurzweil, "We will successfully
reverse-engineer the human brain by the mid-2020s."4 However, since we
don't really know how those neurons work to store memories, I am
doubtful the final simulation will resemble anything like a real brain.
Let's look at human brain function to see why reproducing it in a
computer is going to be extremely difficult. Human beings possess high
resolution video input that is "played" in the human brain in nearly
real time. The brain is able to process the images performing pattern
recognition, also nearly in real time. Take a typical teenager playing a
computer game. The brain is able to continuously process the video
signals to detect the bad guys from all the other bits, while receiving
audio input revealing an unseen sniper off screen to the right. The
brain almost automatically sends neural signals to the extremities to
produce fine motor movements to shoot the virtual threats. The person
doing all this raw processing doesn't really have to think about how to
perform any of these skills. They have already been "hardwired" into the
brain through repetitive training of the brain.
Computers don't work
that way (at least not yet). The computer runs a program that performs
exactly the same steps it has been programmed to do. In response to the
same question, the computer will perform the same steps the same way
over and over again. Computer programmers have yet to figure out how to
program software that rewrites itself over time, improving its
performance. As an amateur programmer, I have constructed some pretty
complicated code that does wonderful things. However, the idea making
code that rewrites itself and "evolves" is beyond by ability to
construct in practice. Obviously, this is what needs to be done in order
to make a machine that has true artificial intelligence. Throwing raw
processing power, no matter how fast the computers get, will never equal
intelligence.
Biological immortality
Besides artificial intelligence, one of the main goals of the
Singularity Movement is immortality. Despite the widespread biological
evidence that human beings are fundamentally designed to be mortal,
Singularitarians believe that once we get smart enough through neural
implants we will be able to "fix" our tendencies to fall apart with old
age. According to Aubrey de Grey, head of Strategies for Engineered
Negligible Senescence....
"People have begun to realize that the view of aging being something
immutable - rather like the heat death of the universe - is simply
ridiculous. It's just childish. The human body is a machine that has a
bunch of functions, and it accumulates various types of damage as a side
effect of the normal function of the machine. Therefore in principal
that damage can be repaired periodically. This is why we have vintage
cars. It's really just a matter of paying attention. The whole of
medicine consists of messing about with what looks pretty inevitable
until you figure out how to make it not inevitable."4
The main reason for aging is that differentiated cells are capable of
only a limited number of cell divisions before they are unable to divide
any more. Once they reach this limit, they are unable to divide and
damaged cells are no longer able to be replaced. This is actually a
design feature that results from the way DNA is replicated. Because DNA
is replicated in only one direction, although the two strands are
complementary (going in opposite directions), it must be copied in
pieces. However, the ends of the DNA strands (called the telomeres) can
never be fully copied. This results in a shortening of the telomeres
until, at some point, the telomeres completely disappear and parts of
adjacent genes are shortened, resulting in gene loss.
At some point, gene loss results in the death of the cell. Some cells are able to get around this problem by producing an enzyme called telomerase, which adds bases to the ends of the telomeres before DNA replication, preventing their shortening. Although all cells contain the gene to produce telomerase, it is turned off in most cells. Singularitarians think that this is a bad design and say that by turning on telomerase in all cells, the cells will become immortal, and, by extension, so will we. The problem is that turning on telomerase is part of the mechanism by which normal cells become immortal cancerous cells.
During embryonic development telomerase and other genes are turned on to allow rapid cell division under the control of developmental control genes. As cells differentiate to their final forms, these genes get turned off. Otherwise, continuing cell replication would result in grotesque growth. By turning on telomerase in all cells, mutations to turn on developmental genes results in the formation of cancerous cells, which reproduce uncontrollably without the limitations of the genes that produce differentiation (to cease further replication).
So turning on
telomerase to "solve" the aging problem will actually result in a much
worse cancer problem. Selectively targeting cancer cells for destruction
is still an unsolved problem in medicine. A life that required one to be
on chemotherapy all the time would probably not be one that most people
would choose.
Solve all problems?
Singularitarians think that all this technology is going to solve all
the world's problems. According to Ray Kurzweil, "We will transcend all
of the limitations of our biology."1 What Mr. Kurzweil hasn't counted on
is that some of the people possessing this technology will likely use it
for personal power and the oppression of others. Just think what Adolf
Hitler or Joseph Stalin could have done with all that knowledge and
power! According to C. S. Lewis, "Education without values, as useful as
it is, seems rather to make man a more clever devil."
Fortunately, the
"progress" in bringing all this ability to the despots of the world is
many years off, and most of us will be dead by then. However, some of
our children may end up dealing with the repercussions of unlimited
technology.
The other problem is allowing machines to reach sentience. What kind of
decisions will an extremely intelligent, soulless machine make? What if
they decide that there are way too many human beings on the planet and
that the world would be a better place without many (or maybe all)
humans. It might make logical sense for a machine to kill excess human
beings, but it is not the kind of decision that a rational, living soul
would ever make.
New religion
If you think the Singularity Movement sounds like it has taken on a form
of religious fanaticism, you are not alone. According to Andrew Orlowski,
a British journalist who has written extensively on techno-utopianism,
"The Singularity is not the great vision for society that Lenin had or
Milton Friedman might have. It is rich people building a lifeboat and
getting off the ship." Mr. Kurzweil thinks that human "wisdom" will take
over the universe, saying, "Ultimately, the entire universe will become
saturated with our intelligence. This is the destiny of the
universe."
What Kurzweil seems to have forgotten from his physics
courses is that intergalactic space travel is simply impractical. Even
interstellar space travel would take hundreds to thousands of years, at
minimum. Humans aren't going to be filling the universe anything any time
soon. Dark energy and the accelerating expansion of the universe
guarantees that Kurzweil's prediction will never happen. Science tells
us that the only certain thing about the universe is that all sentient
life is ultimately doomed to eternal destruction. Writing in the
Astrophysical Journal, Lawrence Krauss and Glenn Starkman conclude....
"The picture we have painted here is not optimistic. If, as the current
evidence suggests, we live in a cosmological constant dominated
universe, the boundaries of empirical knowledge will continue to
decrease with time. The universe will become noticeably less observable
on a time-scale which is fathomable. Moreover, in such a universe, the
days - either literal or metaphorical - are numbered for every
civilization. More generally, perhaps surprisingly, we find that eternal
sentient material life is implausible in any universe."5
Besides being able to live forever, Mr. Kurzweil hopes to bring his dead
father back to life.4 Rather than believing in the power of God, Kurzweil believes in the "power" of ideas, stating, "That was kind of
the religion of my family: the power of human ideas."1
Kurzweil has
fallen for the oldest lie in the world, presented by the serpent in the
Garden of Eden, that humans could become like God.6 It is the idea from
the Tower of Babel - that human effort could reach heaven.7
Other players
Technological change is not the only goal of the Singularity Movement.
Related movements, such as the Zeitgeist Movement, the Venus Project,
and Exemplar-Zero seek to completely redefine how world societies
operate. Movements such as the Zeitgeist Movement and the Venus Project
seek to replace capitalism and free trade with a society based upon a
"resource-based economy" in which machines do all the work, all
resources are shared equally, and people can do whatever they want with
their time.
The problem with such movements is that resources are not infinite and somebody has to work to produce the products we use. The idea that all resources should be shared equally has been tried before - it is called Communism. Of course, it did not work because people and greedy and the ones in power always manage to get more than those who are subordinate.
In addition, if all share equally, there is no
incentive to be productive at all. In the Soviet Union under Communism,
productivity went way down and alcoholism went way up.
Any society that
does not reward productivity is prone to failure through the human
propensity for selfishness.
Christianity!
All that Mr. Kurzweil seeks and more is offered by Jesus Christ:
"For God so loved the world, that He gave His only begotten Son, that
whoever believes in Him shall not perish, but have eternal life. (John
3:16)
Not only does the soul who believes in Jesus Christ achieve eternal
life, but is changed into a morally-perfect being with an imperishable,
spiritual body that will never wear out.8 That body won't need to be
repaired, ever, since it would be perfect. In our current universe,
which is governed by the laws of thermodynamics, perfection is
impossible.
Conclusion
The Singularity Movement is an attempt by people with way too much money
to achieve immortality through technology. Since they don't believe in
the existence of God their only chance is to put off death as long as
possible. However, their assumptions that computing power will increase
exponentially past 2020 are flawed, since transistor size is necessarily
limited at atomic scale dimensions. Based upon our understanding of the
human brain, computers neither store nor access information in the same
way brains do.
It seems unlikely that contemporary software programming will ever achieve real artificial intelligence, since brains adapt their programming in response to training, whereas computers do not. A computer that were able to reprogram itself so as to evolve might achieve such a distinction. However, it might also achieve an inflated sense of worth that would subsequently prompt it to eliminate those of lesser worth.
As history has shown, the development of innovation has always been used by evil men to further their evil agendas. That immensely powerful machines would never be used for evil ends seems extremely unlikely. The Singularity Movement will never lead to a universe that becomes "saturated with our intelligence," since intergalactic travel is not possible because of the laws of physics, and recent cosmological studies show that the universe's destiny is permanent heat death with the extinguishment of all sentient life throughout the entire universe.
Singularitarians seek eternal life,
which is only possible through faith in Jesus Christ.
The eternal life
offered through Jesus is superior to any kind of "eternal life" claimed
through the Singularity, because life in heaven will be enjoyed by
morally perfect beings housed in perfect spiritual bodies.
