The Superior Intelligence
Generally Speaking
What do
we mean ? - The superior intelligence would refer to
a race of computers and robots completely different in ability and
functionality of those of today. We expect computers to be able
to learn better without human assistance, understand scenarios and
react independently to events that they come across.
So what
? - Yes, traditional AI (artificial intelligence) programs
already told us of smarter, better and more human friendly computer
systems in the future, but to what level ? Traditional AI allows
the computer to simply make use of information provided in ways
the programmer already defined and act accordingly to them. All
actions and creativity of those programs are only limited to those
preset by programmers. What we are talking about, however, are computer
programs that can learn from observation, apply it new knowledge
to use ; that is they, possess the learning capabilities similar
to any human being. That being said and given their efficient
Is it Possible ?
Software
wise -Today's computer programs are already capable
of learning like humans, by observation, by sounds and find their
way around by trail and error. Some developers have already come
up with robots that are capable of learning and behaving like a
human infant. It is not mainly a problem of software that is hindering
the progress of computer technology but the hardware aspect. Today's
computers simply lack the processing power to match up to the human
brain.
Hardware
wise - We already mentioned the capability in computer
processing power , compared to those of the human brain. By our
estimate, today's very biggest super computers are within a factor
of a hundred of having the power to mimic a human mind. It is only
a matter of time before computers become even more powerful than
the human brain.
How long will it take ?
Right after World War I, rapid improvements
in electromechanical calculators was the first sign of the beginning
of the electronics race. As electronic computers surfaced during
the World War II, the computation speed to price ratio increased
a millionfold.
Since we know that electricity needs
to travel through a conductor, it only made sense that shorter,
smaller circuits and conductors will enable the electricity to travel
faster, hence improving speed of the electrical component.
Once the idea got through, the race
to squeeze "more" into "less" created fierce
competition between markets.Components which made use of vacuum
tubes were abandoned, and transistors took their place. Then, the
transistors themselves were replaced by faster and smaller integrated
circuits. At some point, scientists warned that the "circuit
squeezing days" were over as circuits reached 3 micrometers.
Then, new manufacturing techniques came out and proved the scientists
wrong. Computer circuit developments sped up even more !
As these integrated circuits get
more and more packed with circuits that grew increasing smaller
by the day, they became so integrated, that they actually became
microchips . Today's microchips producers can squeeze a few million
circuits and transistors all into a chip the size of a pin head
!! The small problem involved here was that the less than 0.1 micrometer
circuits were so fragile and heat sensitive that they would melt
down when the chips get too hot. As a result, the chips are kept
under controlled temperatures by intensive cooling. (E.g. liquid
helium baths)
It was not long before the question
of "how much more can we squeeze the circuits ?" popped
up again. Circuit sizes seem to be reaching a size that seem too
small to be compressed even more and even if they were, the heat
heat and other electrical interference generated would destroy the
fragile circuits and signals would leak from them.
The problem has fortunately found
a new solution, by a technique that seem even more unlikely ; to
shrink the circuits even more. Because traditional circuits still
use the property of forcing massive loads of electrons along tiny
little circuits, they cause great problems about the amount of interference
they can take. With this new class of components known as single-electron
transistors and quantum dots, which work by the interference of
electron waves, larger amounts of interference energy are needed
to cause disruptions. These single electron transistors even work
better as they shrink in size !! Instead of making war with the
inference energy, scientists actually make use of them.
The pace of improvements in computer
performance is rapid. In the 1980s, computer performance doubled
every one and a half years. In the late 1990s, computer performance
doubled with periods of a single year !
If the pace continues, and computer
technology continues improving even more rapidly by the day, computers
matching human performance would be possible in more than a decade
and human like robots will appear in the 2020s !!!
Would we actually do it ?
Even today, the current technology
is just barely good enough (but possible) for us to create our own
"digital human" should we want it badly enough. We mentioned
that we are just a fraction away from building a computer system
matching the processing power of the human brain. The main barrier
involved was cost. Building a system that powerful would take hundreds
of billions of dollars and not many investors would be willing to
sponsor any enthusiastic researchers and scientists with that amount
of money.
We would expect many of you to ask : Why wouldn't anybody be interested
?
First of all, why would we waste
such a massive amount of money and human resource into building
a single,
"fake " human when so many real life humans are already
out in the populations ? It is jst not economical to the investor's
pockets because the "product" would not be at all that
useful.
The most powerful experimental super
computers today are not used to research AI, or to imitate a human
brain but are instead used for stimulations of real life events
which are too complicated for normal calculations. While, they are
powerful enough to do a partial imitation of the human brain, they
will most likely not be used for that cause. This is again, because
it is not economical. The investors and businessmen who funds such
projects are not likely to waste their money on unproductive experiments
that would cause so much.
While there are curious funders who
pour money into AI and robotics projects that produces interesting
results like a robot that can imitate a babie's curious behavouir,
and robots that can create facial expressions themselves by responding
to their "moods", such investors are rare and often invest
only for fun and not for serious interest.
Until the cost of building a digital
human brain is cheap enough, it will be hard to expect to see human-like
robots walking around in the streets like in the movies any time
soon.
