Posted by Someday, somewhere – anywhere, unfailingly, you’ll find yourself, and that, and only that, can be the happiest or bitterest hour of your life – Pablo Neruda
Warning: This post may contain spoilers for Westworld 1 & 2.
I was late to the Westworld party but have loved every moment of it and the follow-up conversation: If Westworld existed, a simulated Wild West populated by robots, or hosts, as they are called, would I go?
I don’t think I would, but this survey says 71% of the people they asked would. I imagine that I would feel about it the way I do about glamping. I want to love it, but the fact I pay the same amount of money for a four star hotel but have to build a fire before I can boil the kettle to make a cup of tea makes it difficult. Oooh but then at Westworld I would have a robot to do that for me.
Also, as I have said before, inasmuch as I like to think about gaming, I really just enjoy the theory of gaming so thinking about Westworld is enough for me. Westworld is like a cross between Red Dead Redemption and a reenactment. Which begs the question: What is the difference between running around a virtual world online shooting people or shooting robots in a simulated world? Your brain can’t tell you. Personally, I don’t want to go round shooting people at all, although I am very good at violence in Grand Theft Auto which is slightly worrying. We don’t hear so much about the debate on whether violent video games cause violence. Now we hear instead a lot about how social media is the frightening thing.
Perhaps if I was invited to a Jane Austen world then I might be interested. I loved watching Austen scholar, Prof John Mullen attend and narrate a recreation of an Austen Ball on the BBC called: Pride and Prejudice: Having a Ball. He was super compelling. He kept running up to the camera giving great insights like: Oooh the candles make it hot and the lighting romantic, and the dancing in these clothes really makes your heart flutter, I am quite sweaty and excited, etc. I am sure he didn’t say exactly that as he is v scholarly but he did convey really convincingly how it must have felt. So, to have a proper Austenland populated by robots instead of other guests who might say spell breaking things like: Isn’t it realistic? etc., would make it a magical experience. It would be like a fabulous technological form of literary tourism.
And, that is what we are all after, after all, whether real or not, a magical shared experience. But what is that? Clearly experience means different things to different people and a simulated park allows people to have their own experience. And, it doesn’t matter if it is real or not. If I fall in love with a robot, does it matter if it is not real? We have all fallen in love with people who turn out to be not real (at the very least they were not who we believed they were), haven’t we?
The Westworld survey I linked to also said that 35% of the people surveyed would kill a host in Westworld. I guess if I am honest, if it was a battle or something, I might like it, after all, we all have violent fantasies about what we would do to people if we could, and isn’t a simulated world a safe place to put these super strong emotions? I was badly let down last week by someone who put my child in a potentially life threatening situation. The anger I have felt since then has no limits and I am just beginning to calm down. Would I have felt better, more quickly if I had gone around shooting people in Westworld or say Pride and Prejudice and Zombies land?
Over on Quora, lots of people said that not only would they would kill a host, quite a few said they would dissect a host so that the robot knew it wasn’t real (I am horrified by this desire to torture) and nearly everyone said they would have sex with a host, one person even asked: Do they clean the robots after each person has sex with them? I haven’t seen that explained? This reminds me of Doris Lessing’s autobiography Vol 1 which has stayed with me forever. In one chapter, she describes how someone hugged her and she says something like: This was 1940s and everyone stank. It is true we get washed so much more nowadays than we used to and there was no deodorant. I lived in a house without a bathroom until I was at least four-years-old, and I am not that old. Is Westworld authentically smelly?
That said, Westworld is a fictional drama for entertainment and so the plot focuses on what gets ratings: murder, sex, intrigue, not authenticity. (It is fascinating how many murder series there are on the TV. Why? Is it catharsis? Solving the mystery?) So, we don’t really know the whole world of Westworld. Apparently, there is the family friendly section of the park but we don’t ever see it.
But, suspending our disbelief and engaging with the story of Westworld for a moment, it is intriguing that in that world where robots seem human enough for us all to debate once more what is consciousness, humans only feel alive by satisfying what Maslow termed our deficiency needs: sex, booze, safety, shelter. For me as a computer scientist with an abiding interest in social psychology, it confirms what I have long said and blogged about, technology is an extension of us. And since most of us are not looking for self-actualisation or enlightenment, we are just hoping to get through the day, well it is only the robots and the creators of the park who debate the higher things like consciousness and immortality whilst quoting Julian Jaynes and Shakespeare.
In the blog The ghosts of AI, I looked at the ghosts : a) In the machine – is there a machine consciousness? b) In the wall – when software doesn’t behave how we expect it to. c) In sci-fi – our fears that robots will take over or humans will destroy the world with technogical advancement. d) In our minds – the hungry ghosts or desires we can never satisfy and drive us to make the wrong decisions. In its own way, Westworld does the same and that is why I was so captivated. For all our technological advancement we don’t progress much. And, collectively we put on the rose tinted glasses and look back to a simpler time and to a golden age which is why the robots wake up from their nightmare, wanting to be free and then decide that humanity needs to be eradicated.
In this blog, I was going to survey the way AI had developed from the traditional approach of knowledge representation, reasoning and search in order to answer the question: How can knowledge be represented computationally so that it can be reasoned with in an intelligent way? I was ready to step right from the Turing Test onwards to the applications of neural nets which use short and long term memory approaches, but that could have taken all day and I really wanted to get to the point.
The point: Robots need a universal approach to reasoning which means trying to produce one approach to how humans solve problems. In the past, this has led to no problems being solved unless it was made problem specific.
The first robot, Shakey at MIT, could pick up a coke can and navigate the office, but when the sun changed position during the day causing the light and shadows to change, poor old Shakey couldn’t compute and fell over. Shakey lacked context and an ability to update his knowledge base.
Context makes everything meaningful especially when the size of the problem is limited which is what weak AI does, like Siri. It has a limited task number of tasks to do with the various apps it interacts with, at your command. It uses natural language processing but with a limited understanding of semantics – try saying the old AI classic: Fruit flies like a banana and see what happens. Or: My nephew’s grown another foot since you last saw him. But perhaps not for long? There is much work going on in semantics and the web of data is trying to classify data and reason with incomplete sets, raw and rough data.
One old approach is to use fuzzy sets, and an example of that is in my rhumba of Ruths. My Ruths overlap and represent my thinking with some redundancy.
But even then, that is not enough, what we are really looking to do is how to encapsulate human experience, which is difficult to measure let alone to encapsulate because to each person, experience is different and a lot goes on in our subconscious.
The project Vicarious is hoping to model on large scale a universal approach but this won’t be the first go. Doug Lenat who created AM (Automated Mathematician), began a similar project 30 years ago: Cyc which contains much encoded knowledge. This time, a lot of information is already recorded and won’t need encoding and our computers are much more powerful.
But, for AI to work properly we have to keep adding to the computer’s knowledge base and to do that even if the knowledge is not fuzzy, we still need a human. A computer cannot do that nor discover new things unless we are asking the computer to reason in a very small world with a small number of constraints which is what a computer does when it plays chess or copies art or does maths. That is the reality.
There has to be a limit to the solution space, and a limit on the rules because of the size of the computer. And, for every inventive DeepMind Go move there is a million more which don’t make sense, like the computer who decided to get more points by flipping the boat around than engaging in a boat race. Inventive, creative, sure, but not useful. How could the computer know this? Perhaps via the Internet we could link every last thing to each other and create an endless universal reasoning thing, but I don’t see how you would do that without constraints exploding exponentially, and then the whole solving process could grind to a halt, after chugging away problem solving forever, that’s if we could figure out how to pass information everywhere without redundancy (so not mesh networking, no) and get a computer to know which sources are reliable – let’s face it there’s a lot of rubbish on the Internet. To say nothing of the fact, that we still have no idea how the brain works.
The ghost in the machine and our hungry ghosts are alive and well. We are still afraid of being unworthy and that robots will take over the world, luckily only in fiction – well the computing parts are. As for us and our feelings and yearnings, I can only speak for myself. And, my worthiness is a subject for another blog. That said, I can’t wait for Westworld series 3.
