6 degrees of Separation – Time Shelter

This is a post in the 6 Degrees of Separation run by Kate W. over at books are my favourite and best in which she gives the starting point of a particular book and invites you to take a journey through 6 other books of your choice, all connecting in some way and perhaps ending up back at the beginning – why not have a go yourself? Challenges are to writing, what scales and arpeggios are to those learning musical instruments, they exercise the faculties, but unlike scales, this challenge is most enjoyable, teasing out as it does, the connections, at a thinking level, between books…

In Time Shelter a 2020 novel by Bulgarian author Georgi Gospodinov, Gaustine, a psychiatrist, creates a clinic for people with Alzheimer’s disease in Zürich which works by immersing patients into rooms containing articles from past decades and stimulating their memories of that period. The narrator is tasked with collecting the artefacts with which the rooms are stocked and travels throughout Europe to complete his mission. But soon the clinic is attracting healthy people who also want to escape a mundane present reality and return, nostalgically to other decades.

This rang a massive bell with me because some thirty-five years ago, I came into contact with a charity called Age Exchange in London, propelled by Pam Schweitzer MBE who pursued funds with the indomitable spirit that is ideal for such a role. They did exactly what the fictional clinic did – trained reminiscence workers to assist suitable dementia patients in recovering memories from the past using a library of artefacts gathered by the charity in Blackheath. The Exchange part of the charity’s name arose because they gathered reminiscences on various themes such as “Can we afford the Doctor?” and turned them into plays (that one was about Britain before the National Health Service) and performed them in schools thus recycling memories through the generations!

Time Shelter is a satire on nostalgia, populism, irony and melancholy and though I had not read it, I have ordered a copy…

Timequake is a 1997 novel by Kurt Vonnegut Junior (yes – him again!) in which he makes the world relive a decade of their lives with no possibility of change – a study of determinism in which he asserts that people have no free will. As so often with Vonnegut, he weaves personal and family history into the tale with the wry humour which is his hallmark. I think I read this book so long ago that it was back when I still used libraries to source my reading material…

The Time Traveller’s Wife by Audrey Niffenegger (such a Wagnerian-sounding name!) is a book that I had read before watching the film adaptation and although it was a faithful adaptation of it, I still prefer to imagine a story as told in its original form. This book takes further the idea of not being able to be in control of one’s destiny. The eponymous wife is powerless to know when or for how long her husband will disappear into the past or future including her own any more than her husband who is at the mercy of a genetic mutation that plucks him in and out of his timeline at random, each know things about the other’s past and future at different times, often uncomfortably so. This book is a thought experiment, a “what if” but like much speculative fiction, it ultimately reveals more about how we as human beings are than how we might be in the unlikely event that time travel is possible…

A Connecticut Yankeee at the Court of King Arthur by Mark Twain is a satire about monarchy and feudalism. We meet another hapless time-traveller – a Yankee engineer called Hank Morgan who awakes after a bump on the head, to discover that he is in the past at the court of King Arthur. He decides to use his skill to improve the world with his modern knowledge so the book also celebrates Hank’s homespun ingenuity and his sense of the rightness of democracy. Although he ultimately fails (darn that determinism), the book marked a move by Twain from portraying the America of the Gilded Age, to more progressive values.

If Hank’s time travel left him in the service of King Arthur, then our next hapless hero is forced to become a king having descended, albeit distantly, from Charlemagne. The Short Reign of Pippin IV by John Steinbeck sits on my bookshelf in a very battered state having belonged first to my father as a young man – it was published when I was just two years old. In a kind of false flag operation by the French communist party, Pippin Héristal, an amateur astronomer is proclaimed King of France (in order that the French people may have something to rebel against – which they eventually do!). Like Hank Morgan, Pippin Héristal tries to make the best of what has been thrust upon him by doing what he thinks might make a difference but fate is already against both of them…

In the next link, another man is tested, this time by two different and opposing societies – in The Dispossessed by Ursula Le Guin, the world of Urras is a capitalist society divided into two competing superpowers  – so much like our own world. The habitable, but resource-poor moon of Urras, is Annares and 200 years before, the rebellious factions of Urras have been sent or volunteered to go there where they have formed a society based on anarcho-syndicalism. Given the lack of resources and the inefficiency of the societal model, Annares is not exactly a thriving place to live. The leading character is Shevek, who Le Gin identified as being based on  J. Robert Oppenheimer – often referred to as “the father of the atomic bomb” and who regarded his involvement in the Manhattan Project as that of a physicist and on seeing the first test of the Trinity bomb, said he thought to himself “Now I am become Death, the destroyer of worlds.”. Of the subsequent use of nuclear bombs on Hiroshima and Nagasaki, he told President Truman he felt he had “blood on my hands”, which did not go down well. In The Dispossessed. Shevek has a similar quandary when he tries to develop a General Temporal Theory and is blocked by a jealous superior and frustrated by his obligation to contribute manual work to society. He decides to go to Annares where he is welcomed because the capitalists see in his work, the opportunity to develop a spacecraft that will make crossing to the stars possible. But while capitalism thrives on his work, Shevek becomes involved with a new revolutionary underclass… Once again, Ursula Le Guin gives the lie to the writing maxim that “big issues are dead weights” – you just need to be a brilliant writer to incorporate them into the right story!

After such erudite stuff, the last book of my six may seem a little frivolous in style, but it contains all the elements we have seen on this journey, a man thrust out of his own time and/or place, into a different world in which he must try to do his best to survive, thrive and even contribute what he knows to the betterment of the society he finds himself in. A Princess of Mars (Barsoom) – is a genre-busting novel by Edgar Rice Burroughs, he of Tarzan fame, and in his Barsoom series, he gives us – planetary-romance, fantasy, sword and planet, and post-apocalyptic speculative fiction from before those terms were even minted! This is not a science fiction book that depends on technology such as spacecraft since the hero – John Carter – transitions to Mars without explanation when in a tight spot on Earth and later returns, again without any control on his part. Edgar Rice Burroughs’ works are full of violent action and derring-do, but the breadth and depth of his imagination made him a huge influence on many later writers – Robert A. Heinlein, Arthur C. Clarke, and Ray Bradbury, H. P. Lovecraft, James Cameron, and George Lucas to name a few.

Finally, what links A Princess of Mars back to Time Shelter, is nostalgia – just as the “healthy” people in Time Shelter, are drawn to use the retro rooms of the clinic because they are fed up with their contemporary lives, so A Princess of Mars harks back to a rose-tinted view of American past – the frontier life when the good were good, you knew who was bad, and men were men and women swooned –” “the good old days”…?

Exploring and Evaluating Generative Artificial Intelligence Number Three

I decided to make a Header Image (above) for this little series of posts and have retrofitted it to the two previous posts here and here. So I asked the Midjourney app on Discord, to depict a silver-skinned Android, firstly, standing at an easel painting, and then at a computer typing. I am fairly sure that the AI known as Midjourney had no sense of the irony of asking it to anthropomorphise an Android doing these activities, because current forms of AI are so far from having the sentience required to appreciate concepts as subtle as irony. Spoiler alert, I approached this evaluative exploration with certain preconceptions about the likely conclusion although I didn’t know for sure, how those conclusions might be reached because I didn’t know how AI’s work, in detail. What I am going to show you today is what I have learned, but I am also going to link you to a very erudite analysis of why we should not be worried about AI taking over the world – in a piece calledWhy the AI Doomers Are Wrong“, Nafeez Ahmed explains why the direction of travel of AI development, simply can’t lead to a human-brain-like sentience. I will quote from his article later.

First of all, look at the left-hand side of the header picture, in particular, the easel. On close inspection, you can see that the easel is the wrong way round and that the painter/android, is standing behind the easel. Midjourney produces four images by default, in the remarkable time of about 60 seconds which is almost like magic – indeed, in 1962, Arthur C. Clarke, a science fiction writer, stated in his book “Profiles of the Future: An Inquiry into the Limits of the Possible” that Any sufficiently advanced technology is indistinguishable from magic. So despite the apparent magic of creating these images so quickly, the AI has made a fundamental mistake that reveals that it doesn’t really understand what an easel is or how it should be used. Nafeez Ahmed is mostly talking about text generative interactions with AI – ChatGPT and the like, but what he says below, is equally applicable to images generated by AI…

The stunning capabilities of the new chatbots and their uncanny ability to engage in human-like conversations has sparked speculation about sentience. Yet there is zero tangible evidence of this beyond a sense of amazement.
What many miss is that the amazing nature of these conversations is not a function of an internal subjective ‘understanding’ by an identifiable entity, but rather the operation of algorithms made-up of hundreds of billions of parameters trained on massive datasets of human text to predict words that should follow given strings of text. {…} This is not a breakthrough in intelligence, although it is, certainly, a breakthrough in being able to synthesise human responses to similar questions and thereby mimic patterns in human interaction. This model of AI, therefore, cannot, in itself, generate fundamentally new knowledge or understanding – let alone sentience.

Nafeez Ahmed

Nafeez goes into great detail about how the research is headed in the wrong direction and indeed, how it is unlikely it is that it will ever succeed in equating to human sentience, so if you want to put your mind at rest about a Terminator-style future in which humans are subjugated by machines – nip on over and read the full article. Meanwhile I am going to show you some more examples of how Midjourney gets things “wrong” and how to get the “right” results and what that says about how useful such a programme can be.

You interact with the Midjourney app by sending it a message (just as if it was really an intelligent entity) containing a prompt, and once you receive your four images, you can choose one to enlarge, if you are satisfied with it, or run variations on one or all of them. Here is the prompt that produced the above set of images. “Silver android painting at an easel by Roy Lichtenstenstein” – the AI places most importance on the object at the beginning of the prompt, then on the activity described and lastly, it attempts to produce the images, in this case, in the style of the Pop Artist Roy Lichtenstein – famous for painting s in the style of close-ups of comic book pictures. These close-ups show the dot screens that were used to shade the illustrations of the comic book plus the hard black outlining and Midjourney has picked up well on these style features, particularly the top right and bottom left pictures. The top-left shows a sculpture vaguely resembling an up-cycled easel made of silver and the bottom right shows a silver-skinned figure with dot-screen effect, holding a brush and painting a picture but with no easel. In the [op-right picture, the top of the easel is just showing in the bottom corner and the android “artist” is holding a small blank canvas in her hand and drawing on it. Having seen the header image at top, and these pictures were as near as I could get to what I wanted, from multiple attempts, you can see that what I wanted was an all-over silver-skinned android and in the images above, top-right has a human face although “her” body is robotic – perhaps cyborg is a better description, whilst the other pictures show a sculpture, a woman and a totally abstract figure. So I decided to change the prompts to “Robot” rather than “Android” which produced better results. The reason I had started with “Andriod” was because robots range from automatic hoovers that move around your rooms looking like little miniature flying saucers sucking up dirt to more anthropomorphic devices – which is what I wanted.

“standing silver robot painting at an easel by Roy Lichtenstein” produced(among others) the above image in which the robot, possibly standing, is grasping what looks like the top of an easel but the “painting” does not appear to be on the easel. So I tried “Robot standing painting at an easel” and got this rather cute robot who looks like he is sitting on an invisible chair – “Hey Midjourney” just because you don’t show the chair, doesn’t make it standing!” Notice that with the style reference to Roy Lictensten gone, this image is very different. I would like to show you more of the iterations but Midjourney froze and when I reinstalled it, it had lost the entire session of work – you just can’t get the staff…

Another thing that I have discovered in my experiments, is that both Midjourney and ChatGPT, like to add unspecified embellishments – remember in my first report, how ChatGPT found the correct explanation for the phrase “Cold enough to freeze the balls off a brass monkey” but then added a totally made up explanation? Well Midjourney does the same thing too. Here is a picture of the railway viaduct at Knaresborough in West Yorkshire , an hours drive from where I live.

I wanted to see if Midjourney could produce a collage image using fragments of maps which it tried but didn’t really understand the concept – although I am not saying that it can’t, but at the very least, my prompt wasn’t sufficient (one of the oldest sayings amongst computer programmers is “Garbage in – garbage out!”) Here is Midjourneys best effort…

There are some map elements and the whole scene has been chopped up and rearranged but not in a way that makes sense – this one is closer to the real view…

But my first attempt, before I added the collage style, was simply to see how Midjourney would find and represent the viaduct and it generated the four images below. The top left image, Midjourney has added another railway running beneath the viaduct, likewise, lower-left it has added a canal and in the images on the right, Midjourney has transported us into a past sans Knaresborough and a post apocalyptic future where vegetation is growing over the viaduct.

Enough with all the pretty pictures – what does all this reveal about the way that the AI Midjourney works! Referring to the work – Erik J. Larson in his book, The Myth of Artificial Intelligence, Nafeez Ahmed cites a summary of the work by Ben Chugg, lead research analyst at Stanford University (Iknow – quotes within quotes) as follows:-

“Larson points out that current machine learning models are built on the principle of induction: inferring patterns from specific observations or, more generally, acquiring knowledge from experience. This partially explains the current focus on ‘big-data’ — the more observations, the better the model. We feed an algorithm thousands of labelled pictures of cats, or have it play millions of games of chess, and it correlates which relationships among the input result in the best prediction accuracy. Some models are faster than others, or more sophisticated in their pattern recognition, but at bottom they’re all doing the same thing: statistical generalization from observations.
This inductive approach is useful for building tools for specific tasks on well-defined inputs; analyzing satellite imagery, recommending movies, and detecting cancerous cells, for example. But induction is incapable of the general-purpose knowledge creation exemplified by the human mind.”

https://towardsdatascience.com/the-false-philosophy-plaguing-ai-bdcfd4872c45

Nafeez goes on:-

Current AI has become proficient at both deductive and inductive inference, with the latter becoming a primary focus.
Larson points out that human intelligence is based on a far more creative approach to generating knowledge called ‘abduction’. Abductive inference allows us to creatively select and test hypotheses, quickly eliminate the ones which are proven wrong, and create new ones as we go along before reaching a reliable conclusion. “We guess, out of a background of effectively infinite possibilities, which hypotheses seem likely or plausible,” writes Larson in The Myth of Artificial Intelligence. {…}
And here is Larson’s killer diagnosis: We don’t have a good theory of how abductive inference works in the human mind, and we have no idea how to recreate abductive inference for AI: “We are unlikely to get innovation if we choose to ignore a core mystery rather than face it up,” he writes with reference to the mystery of human intelligence.
Before we can generate genuine artificial intelligence that approaches human capabilities, we need a philosophical and scientific revolution that explains abductive inference. “As long as we keep relying on induction, AI programs will be forever prediction machines hopelessly limited by what data they are fed”, explains Chugg

To relate this back to my experiments with Midjourney, the AI could identify what an easel looked like and include it in an image but it didn’t really know what it was or how it was used. Easels are probably present in thousands of pictures of artist’s studios as well as adverts but I bet there isn’t a Painters 101 that “First you will need an easel and this is how you use it” because when a human artist goes into a studio and sees canvasses fixed into easels, even if he has never seen one before, he is there to paint canvasses and it is obvious what they are and what they are for. It might be obvious to a human being with our ability to use inference, deduction and abductive capabilities, but an AI might identify an easel, but without finding a clear description of the usage, it cannot fully fathom how to use it…

As for the the tendency to add extraneous details, well the algorithms that govern Generative AI’s, are designed to mimic human conversational style, so when it has found a relevant answer to the requested information or task, it looks to extend the conversation in what it has learned might possibly follow – it doesn’t know whether it is true or not, because that is way above it’s paygrade ( a metaphor which it probably wouldn’t understand either). This phenomena of AI’s making things up is called hallucination – a very anthropocentric term…

I will make one more report on my attempts to get exactly what I wanted from Midjourney and how I found a compromise to be able to work with the results…

Train Wreck Completed

If you were following this blog during last April’s A to Z Challenge, you will remember that I was attempting to finish a novel, and although I didn’t succeed in that goal, it nevertheless gave me a huge impetus and ten months later, the job is done. The cover, above, I made using photoshop and 3D AutoCAD, and it shows the climactic action at the end of the book, taking place at the LaGrange point where everything hangs in the balance.

‘Train Wreck’ is science fiction, but like much sci-fi, it is really about human beings and in this case, it sets out to explore the Utopian dream through the lens of a sci-fi setting, framed as a mystery/thriller…

Some of you were good enough to leave very helpful comments last April, and should you wish to receive a pdf of the finished book, then please let me know how I can send you a file. I would truly value feedback at this stage as I contemplate how much editing is required – where to expand, trim or omit…
