Google and the AI

I watched this talk yesterday by Kevin Kelly on "The next 5000 days of the web". He once again confirms that Google wants to build an AI and he presents his vision of the web's future as one global machine that everything will be connected to. I agree with him but relating to his first point, that no one would have imagined today's technology to be possible 5000 days ago, I think that his predictions don't go far enough.





Something I'd like to tie in with this is George Dyson's article at The Edge from a few year's back titled Turing's Cathedral. He also talks about how Google is building an AI and how their search technology is in some sense the next level of computer technology by providing semantic indexing(to an approximation at least and I would think that it's continually improving).

All this reminds me of The Technological Singularity. I think it is quite inevitable and is the next step of evolution. I must say that I'm frightened by it to some extent. The future is always opaque but so far humanity has been the most organism on the planet (I think that holds true although perhaps some large companies or the world economy as a whole might also compete for this title) but with the approach of the technological singularity, which I believe will involve the creation of some sort of AI, we will lose that privileged position and that will be a big adjustment for humanity to deal with. I don't think it is necessarily bad and I think it probably is the next step in evolution so it might well be inevitable but I can't help but wonder what our role will be in this brave new world?

Most people I talk to aren't particularly concerned about this. They've never actually said so to me but they remain kinda quiet and don't seem to know what to make of the information almost. I guess perhaps for them it is difficult to conceive of an intelligence bigger than yourself that you are just a part of. For example I see the economy as a fairly complex information processing machine. The analogy I like to use here is to think of humans as cells and the economy as the human body. Each cell just carries out it's own function quite unaware of where it fits into the body (at least I assume so, I don't know very much about Biology) but together they form this complex thing that is a human which can move about and even reason about it's own existence. Similarly even though we only go about our daily lives motivated by money or friends or whatever our personal driver is, we contribute to this bigger organisation whose logic and intelligence doesn't sit in the individual units but rather in the connections between them and the institutions we use (I haven't thought through the details here because to me it seems sufficient to capture the idea that I wanted to express but I assume one could make the analogy better). For me the intelligence sits somewhere in between the actors, in the connections or the rules of the game which makes it a tough thing to get because it's not localised anywhere so that we can point at it and say "You see, and that's where the intelligence is."

I saw my first glimpse of this when I read "The Emperor's New Mind" by Roger Penrose in the passage where he describes John Searle's Chinese Room thought experiment. This was many years ago now so I'm not 100% sure anymore what he was trying to say but my basic recollection of it is that Searle was trying to argue that apparent forms of intelligence might represent consciousness, so for example a machine that could translate Chinese into English perfectly and would pass some sort of form of modified Turing test might not really have any particular intelligence beyond being able to do this task of translation. The way to picture this he said was to think of the translation algorithm as a set of instructions given to a man locked inside some room. All he receives from the outside are pieces of paper that have chinese symbols/sentences on them which he doesn't understand one bit. He then applies his instructions/the algorithm to these symbols to turn them into English letters, words and sentences which he returns back to the person outside the room. We ignore questions of time and practicality since this is a thought experiment. To the person on the outside it might appear that this person speaks perfect Chinese but we know of course that he is just mechanically following his algorithm and has no knowledge of Chinese whatsoever. What this showed to me however is not that this clearly shows there is no intelligence here but rather that we should not look for the intelligence in the execution unit (the human in the room in the thought experiment) but rather that the intelligence sits in the algorithm and becomes manifest in the execution of it. Of course if we look for consciousness it gets a little trickier but I'm not even sure what consciousness is and it could well be just special form of intelligence about observing oneself or ... look I don't really have a clue and don't want to get into that here.

I think what is rather startling about the previous example is that it's very difficult to localise the intelligence. I would say the algorithm is the intelligence but an algorithm is such an abstract entity without any real physical form. I mean we could represent it in spoken language and then store it in the man's brain, or we could write it on paper or perhaps we could even encode it in a system of knots on strings or some other form. The algorithm itself is abstract but we interact with it through physical representations. The algorithm is almost like one of Plato's perfect forms that exists in a world of ideas and not our world. So to exist the intelligence exists "inside it" is difficult to get one's mind around. But I think that's how it is or at least how I see it.

Now to tie this all together. I think the web is a giant intelligence much like Kelly said in the video and even though at the moment there is no HAL that we can point at and say that's where the intelligence sits, it is inherent in all the information and the connections and the structures that we have put in place and it probably has already surpassed the intelligence of any individual human. I think it is the process of evolution of continually assembling systems of evermore complexity and we were just one step along the way.
