Why Machines Will Never be Conscious
Below is the text of my bet on Long Bets. Go there to vote.
"By 2050 no synthetic computer nor machine intelligence will have
become truly self-aware (ie. will become conscious)."
Spivack's Argument:
(This summary includes my argument, a method for judging the
outcome of this bet and some other thoughts on how to measure
awareness...)
A. MY PERSPECTIVE...
Even if a computer passes the Turing Test it will not really be
aware that it has passed the Turing Test. Even if a computer seems
to be intelligent and can answer most questions as well as an
intelligent, self-aware, human being, it will not really have a
continuum of awareness, it will not really be aware of what it
seems to "think" or "know," it will not have any experience of it's
own reality or being. It will be nothing more than a fancy
inanimate object, a clever machine, it will not be a truly sentient
being.
Self-awareness is not the same thing as merely answering questions
intelligently. Therefore even if you ask a computer if it is
self-aware and it answers that it is self-aware and that it has
passed the Turing Test, it will not really be self-aware or really
know that it has passed the Turing Test.
As John Searle and others have pointed out, the Turing Test does
not actually measure awareness, it just measures information
processing---particularly the ability to follow rules or at least
imitate a particular style of communication. In particular it
measures the ability of a computer program to imitate humanlike
dialogue, which is different than measuring awareness itself. Thus
even if we succeed in creating good AI, we won't necessarily
succeed in creating AA ("Artificial Awareness").
But why does this matter? Because ultimately, real awareness may be
necessary to making an AI that is as intelligent as a human
sentient being. However, since AA is theoretically impossible in my
opinion, truly self-aware AI will never be created and thus no AI
will ever be as intelligent as a human sentient being even if it
manages to fool someone into thinking it is (and thus passing the
Turing Test).
In my opinion, awareness is not an information process at all and
will never be simulated or synthesized by any information process.
Awareness cannot be measured by an information processing system,
it can only be measured by awareness itself---something no formal
information processing system can ever simulate or
synthesize.
One might ask how it is that a human has awareness then? My answer
is that awareness does not arise from the body or the brain, nor
does it arise from any physical cause. Awareness is not in the body
or the brain, but rather the body and the brain are in awareness.
The situation is analagous to a dream, a simulation or virtual
reality, such as that portrayed in the popular film "The
Matrix."
We exist in the ultimate virtual reality. The medium of this
virtual reality is awareness. That is to say that whatever appears
to be happening "out there" or "within the mind" is happening
within a unified, nondualistic field of awareness: both the
"subject" and the "object" exist equally within this field and
neither is the source of awareness.
This is similar to the case where we project ourselves as dream
protagonists in our own dreams---even though our dream bodies
appear to be different than other dream-images they are really
equally dream appearances, they are no more fundamental than
dream-objects. We identify with our dream-bodies out of habit and
because it's practical because the stories that take place appear
from the perspective of particular bodies. But just because this
virtual reality is structured as if awareness is coming from within
our heads, it does not mean that is actually the case. In fact,
quite the opposite is taking place.
Awareness is not actually "in" the VR, the VR is "in" awareness.
Things are exactly the opposite of how they appear. Of course this
is just an analogy---for example, unlike the Matrix, the virtual
reality we live in is not running on some giant computer somewhere
and there is no other hidden force controlling it from behind the
scenes. Awareness is the fabric of reality and there is nothing
deeper, nothing creating it, it is not running on some cosmic
computer, it comes out of of nowhere yet everything else comes out
of it.
If we look for awareness we can't find anything to grasp, it is
empty yet not a mere nothingness, it is an emptiness that is awake,
creative, alert, radiant, self-realizing.
Awareness is empty and fundamental like space, but it goes beyond
space for it is also lucid. If we look for space we don't find
anything there. Nobody has ever touched or grasped space directly!
But unlike space, awareness can at least be measured directly--it
can measure itself, it knows its own nature.
Awareness is simply fundamental, a given, the underlying
meta-reality in which everything appears. How did it come to be?
That is unanswerable. What is it? That is unanswerable as well. But
there is no doubt that awareness is taking place. Each sentient
being has a direct and intimate experience of their own
self-awareness.
Each of us experiences a virtual reality in which we and our world
are projections. That which both projects these projections and
experiences them is awareness. This is like saying that the VR
inherently knows its own content. But in my opinion this knowing
comes from outside the system, not from some construct that we can
create inside it. So any awareness that arises comes from the
transcendental nature of reality itself, not from our bodies,
minds, or any physical system within a particular reality.
So is there one cosmic awareness out there that we are all a part
of? Not exactly, there is not one awareness nor are there many
awarenesses because awareness is not a physical thing and cannot be
limited by such logical materialist extremes. After all if it is
not graspable how can we say it is one or many or any other logical
combination of one or many? All we can say is that we are it,
whatever it is, and that we cannot explain it further. In being
awareness, we are all equal, but we are clearly not the same. We
are different projections and on a relative level we are each
unique, even though on an ultimate level perhaps we are also
unified by being projections within the same underlying continuum.
Yet this continuum is fundamentally empty, impossible to locate or
limit, and infinitely beyond the confines of any formal system or
universe, so it cannot really be called a "thing" and thus we are
not "many" or "one" in actuality, what we really are is totally
beyond such dualistic distinctions.
Awareness is like space or reality, something so fundamental, so
axiomatic, that it is impossible to prove, grasp or describe from
"inside" the system using the formal logical tools of the system.
Since nothing is beyond awareness, there is no outside, no way to
ever gain a perspective on awareness that is not mediated by
awareness itself.
Therefore there is no way to reduce awareness to anything deeper;
there is no way to find anything more fundamental than awareness.
But despite this awareness can be directly experienced, at least by
itself.
That which is aware is self-aware. Self-awareness is the very
nature of awareness. The self-awareness of awareness does not come
from something else, it is inherent to awareness itself. Only
awareness is capable of awareness. Nothing that is not aware can
ever become aware.
This means awareness is truly fundamental, it has always been
present everywhere. Awareness is inherent in the universe as the
very basis of everything, it is not something anyone can synthesize
and we cannot build a machine that can suddenly experience
awareness.
Only beings who are aware already can ever experience awareness.
The fact that we are aware now means that we were always aware,
even before we were born! Otherwise we never could have become
aware in the first place!
