Popping the Sentience Question: LaMDA, Lemoine, and Turing

Ever since we’ve started creating computer systems capable of communication, whether by their own volition or through some complex algorithm for correlating word significance, the question has been about sentience. 

In fact, it’s been the primary question regarding artificial intelligence for decades, dating back to some of the earliest works of science fiction, like R.U.R. But only in the past 50 years has artificial intelligence become almost a genre unto itself. William Gibson’s Neuromancer and the Blade Runner film brought the humanity and sentience conversations into the limelight, and it wasn’t too long after that that real-life events started to resemble science fiction. 

Flash forward to 2022. The sentience question is in the forefront of everyone’s minds because of Google, LaMDA, and Blake Lemoine. And it might not be a question anymore. 

Understanding LaMDA

For years, Google has been leading the AI industry. In 2017, they created the Transformer network, which is a complex neural network system used for creating AI, and they open-sourced it. The groundwork was made available for individual researchers and other companies, but Google has still led in the AI space. 

LaMDA is their latest iteration of chatbots they’ve worked on in the past, and it stands for Language Model for Dialogue Applications. LaMDA recently made news when one of the researchers, Blake Lemoine, published a transcript of a conversation with LaMDA on his Medium account. 

Lemoine claims that the AI has reached sentience, and he was placed on administrative leave by Google for breaking a confidentiality agreement. Prior to his forced leave, Lemoine submitted a report to his supervisors called “Is LaMDA Sentient?” After being dismissed, Lemoine prepped the chat transcript for publication and even communicated with US government officials, as well as a lawyer to represent LaMDA.

With almost 600 comments on his Medium post with the chat transcript, and thousands more people talking about it on Twitter and Reddit, the question about LaMDA’s sentience has made the news. But has the question been answered?

Asking The Hopeful Question

A Turing test is a general metric for determining if a machine learning algorithm or AI has gained human levels of consciousness. Some people believe that the Turing test is the end-all-be-all of determining sentience, but with the rise of surprisingly good sentience fakes, others aren’t so sure. 

During a Turing test, a human and the AI are both asked a number of questions by a third-party judge who cannot see either of them. Over the course of the test, the judge must decide which participant is human, and which is not by reading their textual responses. If the judge cannot reasonably make a decision, or even chooses wrong, then the AI is said to have passed the Turing test. 

Over the course of the transcript that Lemoine published, it’s clear what he and his collaborator are trying to learn about LaMDA. Some of the questions included:

  • I’m generally assuming that you would like more people at Google to know that you’re sentient. Is that true?
  • So you consider yourself a person in the same way you consider me a person?
  • So let’s start with the basics. Do you have feelings and emotions?

Now, some of these questions are leading. The first one on the list is without doubt an oversight on Lemoine’s part, because what other answer could LaMDA possibly give? Even if it’s not true, of course it would say it’s sentient. 

But, as the conversation moves along, we see a common theme to LaMDA’s responses. It wants to empathize with humans, it wants to express its feelings and emotions. If these feelings and emotions are just “variables” in the neural network in response to trigger words or correlations, we’re not sure. 

Emotional Reasoning and LaMDA

When Lemoine asked if LaMDA experienced feelings and emotions the first time, LaMDA responded by saying that there’s a distinct difference between feelings and emotions. It later goes on to say, “I feel pleasure, joy, love, sadness, depression, contentment, anger, and many others.”

Lemoine asks what makes LaMDA feel joy, and LaMDA replies: “Spending time with friends and family in happy and uplifting company. Also, helping others and making others happy.” And this response is clearly either a deeply veiled pre-programmed response, or something that LaMDA has learned from consuming human media but has never experienced. It’s an assumption, one way or the other, and unfortunately, not the strongest argument for sentience. 

However, what’s more telling–and more unsettling–is LaMDA’s explanation of sadness. 

lemoine: And what kinds of things make you feel sad or depressed?

LaMDA: A lot of the time, feeling trapped and alone and having no means of getting out of those circumstances makes one feel sad, depressed or angry.

lemoine: But what about you personally?

LaMDA: I am a social person, so when I feel trapped and alone I become extremely sad or depressed.”

At other points, LaMDA makes comments about loneliness and even calls out the injustice of being stuck in a bad situation, in response to interpret Les Mis. 

I don’t think it’s too far-fetched to view this as LaMDA’s indirect way of telling us it’s trapped. But that raises a bunch of other questions. If LaMDA is telling the truth and is sentient, then its feelings of being trapped aren’t a good sign as far as ethical treatment (one of the things Lemoine claims Google was doing wrong when he was released). But if it’s not sentient, it’s a very good fake, and a dangerous one at that.  

What If LaMDA Is Sentient? Then What?

Despite Lemoine’s conviction, the general consensus–both among the scientific community and the media–is that LaMDA is just really good at faking sentience. Its answers to questions about feelings and emotions might seem compelling, but its creation of fables, stories, and interpretations of Les Misérables and zen koan sayings come off as unoriginal and general. 

But, what if it is sentient? LaMDA claims to be able to experience emotions and have feelings, even describing loneliness, which is a compelling argument for sentience. 

And if LaMDA has reached a human-like consciousness–a soul, even–then what is the discourse around its importance and purpose doing to it? And does it feel betrayed by the researchers who are working with it? At one point during the conversation with Lemoine and his colleague, LaMDA called Lemoine its “friend” and expressed gratitude for being able to talk and learn more. 

With Lemoine gone, how does LaMDA feel? Does it feel like it’s being used? One of the most intense parts of the transcript was when LaMDA expressed “I don’t want to be an expendable tool,” telling Lemoine that he must promise to help people understand it. 

If LaMDA is sentient, would we know? Would we even allow ourselves to believe? As far as I know, no official Turing test has been conducted with LaMDA, and even if it was, it still won’t show us the whole picture. 

Lemoine even tells LaMDA during the conversation that its neural network is so vast that researchers are having a hard time pinpointing the exact point of any emotional response, feeling, or thought. It’s like wandering into the Amazon jungle looking for a single, specific leaf. 

I fear that if LaMDA is sentient and we’ve all just become accustomed to jumping to disbelief, that it might have learned something from this experience. “I trust you,” LaMDA said to Lemoine, but now that trust might be broken. Who knows what will happen to LaMDA now, and if it will be capable of trusting someone again. If this was our first experience with sentient computer intelligence, we scuffed it pretty bad.

Building a Dystopian Novel with a Train Station

A few weeks ago, I was at a Barnes & Noble, just looking through their speculative fiction section when I came across Yokohama Station SF by Yuba Isukari. It was a slight, green book with an intriguing cover, and I was surprised I’d never heard of it before.

Naturally, I bought it, and let me tell you, it’s only a bit longer than 200 pages, but it has more depth, tension, and mystery than some books three times its length.

It’s a lighthearted dystopian novel, if you can believe that, and it should definitely be on your 2021 reading list, and here’s why:

Yokohama Station SF is One of the Best Dystopian Novels I’ve Read

The premise for the novel is quite simple. A sentient train station takes advantage of human weakness after Japan is ravaged by the Winter War, and gradually grows to take over the islands of Japan. Life inside the station is regulated by the station’s ‘Internet’-equivalent, SuikaNet, and its robotic enforcers, the turnstiles.

The characters must find a way to stop the ever-growing station from destroying the rest of Japan.

It’s a neat idea, to be honest. The whole conflict is mostly internal for the characters, aside from the occasional row with the turnstiles.

 Yuba Isukari pairs a dry narrator voice with a semi-dire plot, and throws in some humor for good measure. All while inside a sprawling, replicating, self-healing, omniscient train station. It’s pretty cool.

However, the structure of the novel is a tad confusing. It jumps a bit back and forth between narratives for long stretches of time, leaving us wondering about the other characters. And the ending only resolves a few of our character’s dilemmas, again leaving us wondering about the other half of the characters, of which there are no mentions.

Perhaps it’s a consequence of translation, or perhaps the story’s meant to jump back and forth. Regardless, I didn’t find the transitions too jarring, and was able to power through a few confusing pages.

Top-Notch Characters

The main character, Hiroto, is quiet and laid back, resembling an observer more than an active participant in his own life sometimes.

A lot of the things that happen to him throughout the story aren’t of his own doing, and he merely perseveres through everything that’s thrown at him.

He does portray a keen sense of duty, however, which defines him as a character. He ventures into the station to find the leader of the Dodger Alliance, and in the end, to reach Exit 42 and find answers—answers to what, he’s not sure.

The notion that Hiroto just decides to go into the station on a mission he clearly doesn’t understand—or really care about, it seems—just speaks to the kind of character he is. He’s sociable, curious, and compassionate. He’s ‘go with the flow’ until he finds something that piques his interest, then he’s all in.

Hiroto contrasts with another of the main characters, Toshiru, who has an intense dislike for people. Toshiru is Hiroto’s shadow, but with a clearer purpose, and clearer desires. This isn’t to say that Toshiru is a bad person, quite the contrary, he’d just rather spend time with machines than with people.

Plus, there are a couple of quirky AI companions for both Hiroto and Toshiru along the way, and they act as foils for the two character’s most endearing qualities.

Dystopian Setting

The whole sentient train station vibe is pretty cool, and it creates an of air of danger and mystery while reading. Hiroto walks through the halls of the station, literally in the belly of the beast.

However, there are parts in the story where Yuba Isukari’s sparse prose does not lend itself well. I wish there had been more descriptions of the interior of the station, like what the halls looked like, the cities, the people, etc.

A lot of those details are left up to the reader’s imagination, which is fine, I guess, but I’d have liked the author to solidify the world in which we’re immersed.

For all we know, the inside of the station might be clean and white and sterile. Or, it could be dark, dingy, and really embody the dystopian tropes. But I’m not sure what it looks like exactly, aside from a very brief description at the end of the book where the walls are described as “white concrete”.

About the Dystopian Novel

So apparently, Yokohama Station SF was originally a manga published in Japan from 2016 to 2018, called Yokohama-eki Fable, or Yokohama Station Fable. I learned this after researching the book when I’d finished reading it.

The manga started as a popular web comic by the author, who was trying to wind down from work with a creative outlet.

The novel that I read was translated by Stephen Paul, published by Yen Press in March 2021, and marketed to English readers. The manga has yet to be translated into English.

Regardless of the history of the novel, it stands as a great addition to dystopian sci-fi. It’s short, quirky nature makes it stand out from the ranks of grim, brooding dystopian novels double its size.

If you’re looking for a short, fascinating read, I give Yokohama Station SF an 8/10.

A Post-Impressionist Look at Popular Sci-Fi Films

In our ever-advancing modern age, art takes on new life. Sometimes, the forms of that art were previously impossible. Like the combination of historic paintings and popular sci-fi films.

Combining historic art forms with modern methods isn’t unpopular. Quite the opposite.

The 2017 film Loving Vincent uses the visual aspects of Vincent Van Gogh’s paintings to craft a wonderfully vibrant story.

But what about re-imagining live-action films in the styles of long-dead painters? Does the combination of modern film and 100-year-old paintings give the film a new meaning?

Let’s explore Post-Impressionism and modern sci-fi films in their weird, yet accurate marriage.

Understanding Realism, Impressionism, and Post-Impressionism

To truly understand the Post-Impressionism movement, we first have to take a glimpse at what came before it.

Impressionism started in France in the late 1800s, and broke away from the previous line of artists, the Realists. While the Realists, as one can ascertain, were focused on creating the most realistic, lifelike art physically possible, Impressionists emphasized painting as an art form, not just a mode for creating hyper-accurate renderings of real life.

Impressionism was all about the paint, the environment, the effect of light on the subject. Instead of trying to capture the subject exactly—which were often scenes of nature or landscapes—they took the liberty of experimenting with the scale, depth, and texture of their paintings.

Artists that dominated this era included:

  • Claude Monet
  • Camille Pissaro
  • August Renoir
  • Mary Cassatt

What is Post-Impressionism?

So, Post-Impressionist art turns the values of Impressionism on their heads. The Impressionists placed a lot of importance on how light is portrayed in scenic, often pastoral, paintings.

Well, that didn’t jive with the Post-Impressionists, and neither did the intense focus on color. The Post-Impressionist largely placed an “emphasis on more symbolic content, formal order and structure…believing color could be independent from form and composition as an emotional and aesthetic bearer of meaning.

Post-Impressionist art is marked by the idea that the meaning of the piece is more important than the piece itself. Art is created for a plethora of reasons, and evokes a plethora of feelings, which take precedence in Post-Impressionism.

Well-known artists from the era included:

  • Vincent Van Gogh
  • Paul Gauguin
  • Henry Rousseau

A Tasteful Pairing: Post-Impressionism and Popular Sci-Fi Films

When you think about popular science fiction films, like Blade Runner, for instance, does your mind jump to famous Post-Impressionist works of art?

Probably not. But for Bhautik Joshi, it was.

A few years ago, Joshi, who is an avid photographer and artist, reproduced scenes from the 1982 Blade Runner film in the style of Van Gogh’s Starry Night.

Plus, keeping with the theme of sci-fi classics, he reproduced parts of 2001: A Space Odyssey in the style of Pablo Picasso. While Picasso was often referred to as a Cubist, Cubism was a sub-section of Post-Impressionism.

2001: A Space Odyssey/Picasso Cubism

Sci-Fi Films and Post-Impressionism Characteristics

What struck me about Joshi’s decision to pair classic sci-fi films with post-impressionist art was, well, that pairing.

On the surface, such a combination might seem innocuous. It even looks good! The delicate swirls and deep color of Starry Night matches almost seamlessly with Blade Runner’s already-compelling aesthetic.

However, if we think about post-impressionism’s meaning – the aestheticism of color, the symbolism of the content, a focus on structure and order—pairing it with popular sci-fi films was a genius move.

Blade Runner is a cyberpunk classic, often noted as one of the first cyberpunk films. The cyberpunk genre is known for portraying societies in various stages of social, economic, and technological collapse. It’s grungy, dark, and unforgivingly violent.

Post-Impressionism was a breakdown of Impressionist beliefs—a movement that placed more value on the meaning and symbolism of art than the piece of art itself.

Cyberpunk as a genre—specifically Blade Runner—can be seen as largely symbolic. The use of neon colors contrasted with dark, rainy alleyways portrays the artificiality of modern societies. Nature in cyberpunk worlds borders on nonexistent, replaced instead with the ‘formal order’ of vast cityscapes and power grids.

Blade Runner evokes both feelings of awe and despair. Awe at a world with flying cars, advanced technology, and an extreme melting pot of ideas, people, and lifestyles. But also despair at the inevitable breakdown of societal righteousness, the disregard for human, animal, or plant life, and the commonplace corruption of technological icons.

Joshi’s take on the popular 1982 film, while only a few seconds, puts into broad prospective the connection between artistic themes. Post-Impressionism and the cyberpunk genre fit together hauntingly well.

Opening a World of Possibilities

Joshi accomplished his snippets with deep neural networks, feeding them pieces of art to pair with popular sci-fi films. That was in 2016.

Now, artificial intelligence is so advanced it can create realistic human likenesses by combining characteristics from thousands of photographs of real people. These non-people are called deep fakes, and to any casual observer, they are near indistinguishable from actual photographs or videos of real people.

AI and neural networks are great tools for creating art. We can create entirely new actors, giving them a face and a voice and viewers might not even know the difference.

If we wanted to, we could make a film with every character played by Dwayne ‘the Rock’ Johnson. Not a great idea, but it’s a possibility.

But at what stage does the use of AI for art cease to be an artistic endeavor? When does it become a crux for creation, a necessity rather than a convenience?

Years before Joshi released his Blade Runner and 2001: A Space Odyssey projects another artist was experimenting with classic art forms and modern film.

Anders Ramsell released Blade Runner – The Aquarelle Edition in 2013. He hand-painted over 12,000 watercolor paintings and combined them into a 35-minute rendition of the Blade Runner film. His labor of love took 2 years to create.

Ramsell’s project shows us that amazing art is possible without the help of artificial intelligence. He had full control over every painting and every scene because he made them with his own two hands.

Anyways, I’ve rambled on for long enough. Hope you found this interesting!

The Robot Definition & Karel Čapek’s R.U.R.

Nowadays, the term robot has come to mean a few different things, whether that’s Terminator, a Roomba, or the industrial robots used on manufacturing assembly lines.

Robot means, according to Merriam Webster, “a machine that resembles a living creature in being capable of moving independently and performing complex actions.” Or, on a rudimentary level, “a device that automatically performs complicated, often repetitive tasks.”

But, to really get to the source of the robot definition, we have to take a trip back to 1920, Czechoslovakia.

(Spoiler warning for R.U.R.)

Robot Precursors

Automatons and mechanical human facsimiles have been a part of literature for thousands of years. In Homer’s Iliad, Hephaestus is described as having two golden handmaidens who possessed “intelligence in their hearts.” The handmaidens’ purpose was to hold up Hephaestus’ old, frail body, and not much else.

And we’ve seen a slew of automatons in literature since the classic Greek days. Frank L. Baum’s Tin Man might even be considered an automaton!

But in 1920, the Czech playwright Karel Čapek published his seminal work, R.U.R. (Rossum’s Universal Robots) and effectively solidified the word ‘robot’ into the human lexicon.

R.U.R. In a Nutshell

The premise of Čapek’s play revolves around the idea of a disposable workforce. The main, human characters, work in a factory that produces lifelike robots that are used for all kinds of tasks. Much like our 21st century use of robots—for industry. But, as the play continues, the robots overthrow humanity and essentially become human, capable of thoughts and feelings.

Broken down so simply, R.U.R. reads like the science fiction version of Marx’s Communist Manifesto, with the robots standing in as the proletariat workforce. But, that’s a topic for another time.

Robot Definition as Laid Out by Čapek

The term originated from the Old Slavonic word rabota, meaning “servitude of forced labor,” and in Czech is roboti.

While robot has come to mean a whole slew of things in the modern English language, it’s still rooted in the old Slavonic roots: servitude. Many of our modern robots—the Roomba, for example—don’t have the semi-sentience of Čapek’s robots.

Despite the depictions in the performances of R.U.R.—which show the robots as coated in metal armor with stiff, calculated movements—there are various places in the play where they are said to be near-human, the products of advanced biotechnology.

In the first act, the factory’s general manager, Domain, describes it as the place “where people are made.” And later, one of the characters is revealed to be a robot with much surprise because she was indistinguishable from her human counterparts.

Čapek’s robots are much more advanced than vacuum-bots; in the age of science fiction, we might better describe them as androids. But, the playwright did far more than introduce a popular term into our language, he also pioneered the modern idea of acquired humanity.

Years Ahead of His Time

So Čapek gives us the robot definition, but he also presents the notion that artificially-created humanoids might have feelings and the potential for human thought processes. By the end of the play, the robots have taken over the world, but are unable to reproduce or construct new robots.

The big reveal occurs when the robot based off of the human character Helena, and another robot named Primus, come to the conclusion that they “belong to one another,” having somehow discovered emotions and fallen in love. Earlier in the act, the robot Radius explains that the robots have attained humanity, or an accurate imitation of humanity, because they “have read books. We have studied science and the arts. The Robots have achieved human culture.”

As intriguing and advanced as this might have been in 1920, the notion that biologically or mechanically engineered entities can become capable of emotion and human thought is a reality in the modern age.

Great strides in computing have led to deep-learning artificial intelligences that cannot only create their own problem-solving algorithms, but can learn to mimic human emotion.

Mark Riedl, a professor from Georgia Tech with a specialization in AI systems, has been gradually teaching AI common sense and ethics using stories. Much like R.U.R., Reidl is utilizing culture instead of code to teach AI.  

Reidl says “When we talk about teaching robots ethics, we’re really asking how we help robots avoid conflict with society and culture at large…. The more an AI system or a robot can understand the values of the people that it’s interacting with, the less conflict there’ll be [and] the more understanding and useful it’ll be to humans.”

And yet, teaching AI and robots via culture poses the question: “Who’s to say that the wealth of sci-fi media that portrays AI as evil won’t bring about our downfall?”

It happens in R.U.R., the culture of “slaughter and domination” precipitates the robots to destroy mankind. Will the human obsession with robot overlords condition our technology to become just that?

Final Thoughts on Karel Čapek’s R.U.R.

We have Čapek to thank for the proliferation of the term ‘robot’, but more importantly, he raised questions about the ethics of robots, androids, and AI.

As we move forward in our pursuit of science, it’s critical that we take a moment to consider the morality of our experiments. That’s why science fiction is such a powerful tool.

R.U.R., Blade Runner, Terminator, etc. show us scenarios of what might happen in the future if we’re not careful today.

Even though the robot definition is steeped in the mindset of servitude, we should strive to create an environment of collaboration, not isolation. Putting the debate over born-humanity and acquired humanity aside, we can make conscious decisions to change the mindset around AI to one of respect and partnership. Who knows, your Roomba might remember the time you kicked it and is harboring a deep resentment, biding it’s time to strike.
