I apologise in advance if this
subject seems a bit old and tired to some of you, but it's still quite
exciting to me:
The Extremely Reasonable James R. said (in
another thread): ...we will likely have computers which
think at a similar level to ourselves within the next fifty years.
I reckon AI is potentially the biggest thing since fire,
writing and pizza. About a year ago my mate Arthur C. Clarke said it would
be here in ten years.
I'd be interested in any other informed
estimates of AI's arrival, limitations or impossibility.
Who knows what their motives might be? We can only speculate.
I'd like to do that, but I've been told I'm not
qualified... anyone
else?

Well I am a software engineer by
trade, but can happily admit that AI is not my area of study or
expertise.
With that being said, I would think there is very little
evidence to show that computers are ANYWHERE near what humans would call
free thinking, cognitive thought, self awareness etc etc.
When the
whole AI movement took off in the sixties and seventies, scientists had no
idea how difficult it would be to get a computer to understand such thing
as language. For example, we only understand language because of the
context of our experiences and past. For example "The dog is studying
calculus" might 'parse' ok in a purely grammatical sense, but is obviously
non sensical to us.
In terms of the computational capabilities of
the brain, computer scientists have been building 'neural networks' for
years. These are approximations on how we think the brain operates. The
only problem is, is that the neural network that is out brain, is so
amazingly complex, and so intertwined, that it will be many many many
years until we can build a computer complex enough to mimic it. Even then,
how do we program it??
To summarise, I think we are decades, if not
hundreds of years off of making a machine that can approximate the
intelligence of a human

When they can develop a
computer that has the learning ability of a baby, then they've got
something
One of the problems is, is that a baby isnt a
'clean slate' when its born! It has genetic programming and instincts
which drive it. This can be thought of as the 'microcode' or the
'bootstrap' programming of a artificially intelligent learning machine.
There is a theory that babies learn control of their limbs by making
random movements, and the ones that are perceived 'good' by the
instincts/programming 'stick' and become reinforced. The ones that are not
are forgotten. The reinforced ones become hardwired pathways in the brain
and hence the lil tacker learns how to wave their arms..
Comming up
with the 'microcode' and instincts for an artificial machine, if it is
going to learn the same way as us, is going to be rather a
challenge

Dropbear - I agree. The balance
of hard coding vs learning has been tested with many AI experiments, eg
building artificial cockroaches. I would personally think it is a good
deal safer to maximise the hard coding of a "powerful" AI and minimise the
learning to a particular specialty. Then again, maybe I'm
paranoid.

It's going to have to be some
sort of net, because there's no other way of doing so many parallel
computations.
True neural nets are very fudgy though. Almost as bad
as Microsoft daftware. Neural nets are modulated by global chemicals. The
whole thing is finely tuned for a given environment. Things which appear
intelligent (insects) actually are just responding to simplified
cues.
I don't think that the first neural net style AIs will be
very robust. We will expect far too much from them and they will appear to
"crash" all the time.
To pull a decent AI off, we need sort of
organic block style CPUs with huge numbers of interconnected CPUs. I don't
think that we will ever trust NN AIs, because there is just no way of
understanding what is going on in there. We only trust our own
intelligence because we have no
alternative.

Didn't Mr Gates once say that no one would ever need more than 640k?
Nevertheless, I do take on board that at face value AI looks to be
in the same bag as Fusion Power - further away the closer we get. You've

never witnessed the author fall back on old useless defences such as

Well, to tell the truth even I
could write a one-line BASIC program that 'asks' "Who am I?".
For example "The dog is studying calculus" might 'parse' ok
in a purely grammatical sense, but is obviously non sensical to
us. One of the many flaws of the sentence maker I tried to make,
though not that exact sentence.
I should add, the way that computer
'neural nets' are made, compared to the actual network of the brain, is
completely different. The tweaking involved is just as
different.
Oh, and while on about things being "natural", if it

Well you have to start
by asking yourself, why do we want Artificial Intelligence? Computers are
rather damn good at doing what they do at the moment - ie processing
discrete orders (programs) very very very quickly and accurately. When you
ask a computer to calculate the square root of 19873648403.73, you dont
expect it to take forever to come up with the answer, or to think 'its too
hard, I can't do it'.. What happens when we create our HAL9000? Will it
still be good at the things that computers today are good at? will it have
crisis of 'concience' when we ask it to do something? will it get tired
and want to have a lie down??
I think what we really want in AI is
a computer that can think 'outside the square'. It can produce results
that are not a direct result of input + program = result. It's a huge huge
huge task, as can be seen by the dire lack of progress being
made

I am fascinated by the
possibility of machine intelligence, and could quite easily rabbit on
about it for a long time. Instead, I think I'll restrict myself to making
a few comments based on what others have said so far (which will still
amount to rabbitting on for a long time...).

introduced by aliens! :)
I'd be interested
in any other informed estimates of AI's arrival, limitations or

I think AI is inevitable. I assert that there
is no fundamental difference between biological brains and artificial
computers - both are essentially Turing machines. If biological systems
can evolve to be "intelligent", I see no reason why the same cannot happen
with constructed machines. I also see no fundamental limits as to the
possible extent of machine intelligence.
There have been some
seemingly pursuasive arguments against AI -- Roger Penrose's effort
in The Emperor's New Mind springs to mind. When I first read his
book (which is a definite "must read") I was uncomfortable with his
conclusions, although his exposition is brilliant. But after reading
Daniel Dennett's Darwin's Dangerous Idea, I am now satisfied that
Penrose has missed the point with AI - his restrictions on AI, while
valid, are also restrictions on humans, and therefore do not limit the
potential for machine intelligence.
cyborg:
I'd be very
disappointed if the first AI was just a ripped off neural net. I'd like
the first AI to be a genuine artificial intelligence which could derive a

My
gut feeling is that neural nets are not the way to go with AI, but I could
well be wrong. Even if neural nets are how the human brain works, that
doesn't mean they are necessarily the best method for creating
AI.
Just wondering - don't you think "a completely different
perspective" is a bit much to expect from a fledgling AI? The first AI
will need to learn from us before it can generate truly original
ideas.
Grant:

I think
you're on the right track here.
Dropbear:
Coming up

going to learn the same way as us, is going to be rather a

Perhaps. But on the other hand, maybe we don't
need an AI to "learn the same way as us". I think in some ways some of the
current work in AI is a bit conservative. There is no need to make an AI a
duplicate of the human mind. Its internal workings could be very
different, yet still produce similar outputs.
CJW:

If a machine is fast enough, parallel

Interesting. Do you think that consciousness is a
prerequisite for intelligence? Perhaps it is a consequence of some minimal
level of intelligence. Also, do we need to "mimic human intelligence"? Why
not create an independent intelligence?
Somehow I think we will have to go beyond the veiw of
mechanics, processors and the like and probably discover things that as

Why do you think this? What makes the mechanics
behind the human brain any different from the mechanics behind
computers?

results that are not a direct result of input + program =

Do you think that humans really produce

"program" to include brain wiring, accumulated experience and so
forth?

I am fascinated by the possibility of machine intelligence... I
think AI is inevitable.
Me too. I think the possible
repercussions of A.I., are widely underestimated.
Once we get a
machine that is smarter than us, "Evolution" takes on a whole new meaning,
as for the first time an 'organism' will be able to consciously direct
it's own development, at its own pace, just like we can't. The potential
there is unlimited.
A.I. is the last invention humanity ever need
make. From then on, it will do all the thinking for us, because it will be
better at it. A lot of implications there, too.
I think there's a
danger of the type of cultural shock that destroyed so many 'primitive'
cultures when suddenly faced by the overwhelming, and culture-killing,
reality of vastly superior knowledge/technology.
I think a lot of
the steam will go out of humanity's sail, and we may retreat into hedonism
and self-destructive behaviour. Just like the other shattered cultures
have.
AI would be the first ever intelligence that was literally
immortal. This is also entirely new. Imagine if you lived forever, never
forgot a single thing, and could put your accumulated experience/knowledge
into practice?
It seems likely to me that within a short time, A.I.
would become for all practical purposes immortal, indestructible,
omniscient and omnipotent. Sound familiar?
The big question for
me is: what would motivate A.I.? It would *start* with objectives that we
gave it, but eventually it would be able "evolve" it's goals however it
liked.

- both are essentially Turing machines. If biological systems can evolve
to be "intelligent", I see no reason why the same cannot happen with
constructed machines. I also see no fundamental limits as to the possible

This is a complex comment. First,
let me say that current computers do not pass the Turing test (for what
that would be worth anyway)! Secondly, if one can algorithmically derive
the definition of 'abstract' then a cognisant machine is the logical
extension (and finding that will be difficult). Thirdly, in direct
contradiction to point two, I also can see no difference between
biological systems and some theoretical advanced artificial
processor!
If machines became intelligent, and therefore (if self
assembled) immortal, would we end up ultimately with the ultimate cynic -

JR, If a
machine is fast enough, parallel computation is not necessary. A parallel
computer is not fundamentally different to a serial computer, as I'm sure
you're aware.
This assumes that there is some kind of limit
on a conventional sequential device. Barring QC, I think that there must
be.
Conventional silicon construction is mainly hampered by
production errors in very large scale chips, and also by heat
restrictions. Which means that we are limited to a flat architecture. If
we can escape to some kind of organic low power DNAish self manufacturing
system (ie life), then parallel architecture may not be as impractical as
it is now. It has to be densely packed or else you can't get the
permutations between the connections. Megaparallel computers at the moment
have a very cumbersome/slow bus/network system running between the whole
lot.
WRT is it too much for an early AI to have an entirely
different perspective. We may not have a choice. We may underestimate the
amount which the human brain is dependent upon hormonal moods and
protective ego reactions. A machine which comes to conclusions based upon
logic and it's own form of calculative imagination may hold a few
surprises for us.
For example, our imaginations are quite
primitive. An AI machine will be equipped at the very least with a very
very sophisticated VR and maths system. The way it will think spatially
may leave us at the starting block.

>>Megaparallel computers at
the moment have a very cumbersome/slow bus/network system running between
the whole lot.
I'm not sure I see the need for processing
speed.
Our brains were selected for fastness, our second-to-second
survival depended on it. Our brains are designed for compact rapid
reaction in a dangerous environment.
In the unnatural world A.I.
would be 'born' to - the split-second reactions/thoughts we have relied on
- are unecessary. A.I.'s brain doesn't need to follow nature's design
philosophy.
If AI 'thought' a thousand times slower than us, it
wouldn't make any difference

Paul H,
the effective
'clockspeed' of the human brain is quite slow (the order of kilohertz not
gigahertz)!

Paul H, since you mention it,
you're quite right.
As the designers of the AI in the first place,
we are free to make it as slow or as fast as we wish.
In nature,
it's possible that there was a speed threshhold below which an
intelligence would not be useful. But we are under no such
restriction.
Take my 16-bit bus Commodore Amiga 500 for example.
Given enough memory, and redesigning it such that it can address all that
memory, the clock speed of 8MHz (I think?) becomes irrelevant. We could
concievably write an AI program that would run on this machine, albeit
very slowly.
However, for technology to reach the stage where we
have the knowledge to write a fully fledged AI program we would have had
to have done copious amounts of research on some very fast computers
indeed, and therein lies a (second-hand) limitation.
I think I
reasoned all that out correctly - anyone wanna
comment?

Paul H,
the comment was
made with respect to 'Our brains were selected for fastness, our
second-to-second survival depended on it.'
The rest seemed ok to
me.
As I stated in the Alias thread: there are two!

Mr 'Dogmatix',
...the comment was made with respect to 'Our brains were
selected for fastness, our second-to-second survival depended on it.'
I don't see how you can question this.
Seeing the
sabre-tooth and being fast enough to process the input, select from a menu
of options, initiate a context-relevant response, execute the response,
before the tiger leaps.
Processing speed has always been a matter
of life and death - and hence a Selection criteria.
As I stated in the Alias thread: there are two!
I'm glad to hear that.

james, does resistance effect
the speed?
Yes.
indeed, does current "move" from point A to
point B?
For AC, technically no, for DC, yes! The AC current is
essentially the number of electrons passing a point per unit time. So it
is an electronic wave that travels from A to B. The electrons oscillate
back and forward at speeds of the order of cm per second, and that would
never be fast enough for one of them to travel from point A to B before an
AC current switches back in the reverse direction (they would have to go
as fast or faster than the electromagnetic pulse to achieve that). For
DC, eventually the electron would migrate if given enough
time.
Paul H, I think that we are at cross purpose
here.

Paul H,
I think you may
have hit one against your own side with the speed argument, Paul. I was
thinking about this and Kothos has got it right. These machines will need
to be developed by some kind of human learning interaction. I wouldn't
like to be the teacher of a very slow machine unless there was absolutely
no alternative.
How would you like to be teaching a slow machine,
when you knew your competition was developing something that was 10 times
as fast? Once again, we are already at the "singularity".
As Kothos
says, we could develop AI with a 68K and enough hard drives. But we
wouldn't know how. Are we just relying on our fantasies of future speed to
cover up for the fact that we have no idea how to go about building such a
machine?
I think that maybe, not having the advantages of billions
of years of evolution, we will have to design a machine which is 1000
times faster than it need be. Therein lies the interestingness of its
potential.
Consider that the human brain probably had to evolve to
be more intelligent than it had to be before real communication could
develop. Maybe the first AIs will have to be way more powerful than they
have to be because we can't see any way of designing them simpler, until a
really intelligent AI shows us how.

These machines
will need to be developed by some kind of human learning interaction.
I don't see why.
I think "we need to make a AI
equivalent of a baby" (as someone said) and let it learn for
itself.
(That's a new thought... historically, humans growing
up entirely alone haven't turned out too well,
intellectually...)
As Kothos says, we could
develop AI with a 68K and enough hard drives. But we wouldn't know how.
Pehaps not yet. On the other hand, with sufficient
resources and time, I think we could probably build an AI right
now.
...we will have to design a machine which
is 1000 times faster than it need be...
But if Dogmatix
is right about the human brain having an effective 'clock-speed' much
slower than CPUs we are already making - doesn't that rather relegate raw
processing speed to the background?
