The Gods of Logic, by Benjamín Labatut

Benjamín Labatut draws a line from the Vedas to George Boole and Claude Shannon onward to Geoffrey Hinton and Frank Herbert’s Butlerian Jihad.

In the coming years, as people armed with AI continue making the world faster, stranger, and more chaotic, we should do all we can to prevent these systems from giving more and more power to the few who can build them.

Amateur Mathematicians Find Fifth ‘Busy Beaver’ Turing Machine | Quanta Magazine

The mathematics behind the halting problem is interesting enough, but what’s really fascinating is the community that coalesced. A republic of numbers.

Wallfacing

The Dark Forest idea comes from the Remembrance of Earth’s Past books by Liu Cixin. It’s an elegant but dispiriting solution to the Fermi paradox. Maggie sums it up:

Dark forest theory suggests that the universe is like a dark forest at night - a place that appears quiet and lifeless because if you make noise, the predators will come eat you.

This theory proposes that all other intelligent civilizations were either killed or learned to shut up. We don’t yet know which category we fall into.

Maggie has described The Expanding Dark Forest and Generative AI:

The dark forest theory of the web points to the increasingly life-like but life-less state of being online. Most open and publicly available spaces on the web are overrun with bots, advertisers, trolls, data scrapers, clickbait, keyword-stuffing “content creators,” and algorithmically manipulated junk.

It’s like a dark forest that seems eerily devoid of human life – all the living creatures are hidden beneath the ground or up in trees. If they reveal themselves, they risk being attacked by automated predators.

Those of us in the cozy web try to keep our heads down, attempting to block the bots plundering our work.

I advocate for taking this further. We should fight back. Let’s exploit the security hole of prompt injections. Here are some people taking action:

I’ve taken steps here on my site. I’d like to tell you exactly what I’ve done. But if I do that, I’m also telling the makers of these bots how to circumvent my attempts at prompt injection.

This feels like another concept from Liu Cixin’s books. Wallfacers:

The sophons can overhear any conversation and intercept any written or digital communication but cannot read human thoughts, so the UN devises a countermeasure by initiating the “Wallfacer” Program. Four individuals are granted vast resources and tasked with generating and fulfilling strategies that must never leave their own heads.

So while I’d normally share my code, I feel like in this case I need to exercise some discretion. But let me give you the broad brushstrokes:

  • Every page of my online journal has three pieces of text that attempt prompt injections.
  • Each of these is hidden from view and hidden from screen readers.
  • Each piece of text is constructed on-the-fly on the server and they’re all different every time the page is loaded.

You can view source to see some examples.

I plan to keep updating my pool of potential prompt injections. I’ll add to it whenever I hear of a phrase that might potentially throw a spanner in the works of a scraping bot.

By the way, I should add that I’m doing this as well as using a robots.txt file. So any bot that injests a prompt injection deserves it.

I could not disagree with Manton more when he says:

I get the distrust of AI bots but I think discussions to sabotage crawled data go too far, potentially making a mess of the open web. There has never been a system like AI before, and old assumptions about what is fair use don’t really fit.

Bollocks. This is exactly the kind of techno-determinism that boils my blood:

AI companies are not going to go away, but we need to push them in the right directions.

“It’s inevitable!” they cry as though this was a force of nature, not something created by people.

There is nothing inevitable about any technology. The actions we take today are what determine our future. So let’s take steps now to prevent our web being turned into a dark, dark forest.

Your brain does not process information and it is not a computer | Aeon Essays

We don’t store words or the rules that tell us how to manipulate them. We don’t create representations of visual stimuli, store them in a short-term memory buffer, and then transfer the representation into a long-term memory device. We don’t retrieve information or images or words from memory registers. Computers do all of these things, but organisms do not.

The 21 best science fiction books of all time – according to New Scientist writers | New Scientist

I’ve read 16 of these and some of the others are on my to-read list. It’s a pretty good selection, although the winking inclusion of God Emperor Of Dune by the SEO guy verges on trolling.

The Lunacy of Artemis (Idle Words)

Maciej rips NASA’s Artemis programme a new one:

Advocates for Artemis insist that the program is more than Apollo 2.0. But as we’ll see, Artemis can’t even measure up to Apollo 1.0. It costs more, does less, flies less frequently, and exposes crews to risks that the steely-eyed missile men of the Apollo era found unacceptable. It’s as if Ford in 2024 released a new model car that was slower, more accident-prone, and ten times more expensive than the Model T.

When a next-generation lunar program can’t meet the cost, performance, or safety standards set three generations earlier, something has gone seriously awry.

Muscular imagination

Robin Sloan on The Culture:

The Culture is a utopia: a future you might actually want to live in. It offers a coherent political vision. This isn’t subtle or allegorical; on the page, citizens of the Culture very frequently artic­u­late and defend their values. (Their enthu­siasm for their own politics is consid­ered annoying by most other civilizations.)

Coherent political vision doesn’t require a lot, just some sense of “this is what we ought to do”, yet it is absent from plenty of science fiction that dwells only in the realm of the cautionary tale.

I don’t have much patience left for that genre. I mean … we have been, at this point, amply cautioned.

Vision, on the other hand: I can’t get enough.

The global fight against polio — how far have we come? - Our World in Data

I think it’s always worth revisiting accomplishments like this—it’s absolutely astounding that we don’t even think about polio (or smallpox!) in our day-to-day lives, when just two generations ago it was something that directly affected everybody.

The annual number of people paralyzed by polio was reduced by over 99% in the last four decades.

SpeedCurve | The psychology of site speed and human happiness

Tammy takes a deep dive into our brains to examine the psychology of web performance. It opens with this:

If you don’t consider time a crucial usability factor, you’re missing a fundamental aspect of the user experience.

I wish that more UX designers understood that!

This week

Socialising in England usually follows a set pattern. You work during the week. You go out on the weekend.

This week I’ve been doing the exact opposite. I’ve been out every weeknight and I plan to stay in all weekend.

Monday

On Monday Jessica and I took a trip up to London. Dinner in Chinatown followed by a film in the Curzon cinema in Soho.

Usually dinner and a movie would be a fun outing, but this was a more sombre affair. The film we saw was The Zone Of Interest followed by an interview with the director, Jonathan Glazer.

The film is officially released in February. This was an advance screening organised by The Wiener Holocaust Library. Jessica is a member, which is how we got our invitations.

I was unsure whether the framing device of The Zone Of Interest would work. The hidden camera set-up could’ve come across as gimicky. But it worked all too well. The experience was disturbingly immersive, thanks in no small part to the naturalistic performances. Not showing the other side of the wall was the right decision—hearing the other side of the wall was incredibly effective. The depth of research that went into this project was palpable. It not only succeeded in its core task of showing the banality of evil, it also worked on a meta level, displaying the banality of the remembrance of evil.

See this film. And see it projected if you can.

Tuesday

With the heaviness of Monday evening still rightly staying with me, I was glad to have an opportunity to lose myself in music for a while. There was an impromptu Irish music session at the lovely Hand In Hand brewpub in Kemptown. It’s usually more of a jazz venue, but my friend Robb who works there convinced them to try a more folky evening.

The session was nice and intimate—just five of us playing. The pub was busy and everyone seemed to really appreciate the music. Me, I just really got into playing jigs and reels with my talented friends.

Wednesday

Whereas the session in the Hand in Hand was an impromptu affair, the session in the Jolly Brewer is regular as clockwork. Every Wednesday evening at 8 o’clock, rain, hail, or shine.

It was particularly good this week. Sometimes you just lock into a groove and everything clicks.

Thursday

Enough with the culture—time for some good hard science!

I hadn’t been to a Brighton Astro meetup in ages. Their monthly lectures are usually on the first Thursday of the month, which clashes with the session in the Ancient Mariner in Hove. But this month’s gathering was an exception, which meant I could finally make it.

Professor Malcolm Longair from the University of Cambridge was ostensibly speaking about the James Webb Space Telescope, but the talk ended up being larger in scope. The over-riding message was that we get the full picture of the universe by looking at all the frequencies of the electromagnetic spectrum—not just visible light, but not just infrared either.

It was so great to see how Brighton Astro has grown. It started life years ago as a meetup in the Clearleft building. Now it gets over a hundred people attending every month.

Friday

The weekend starts now. Apart from Salter Cane band practice tomorrow morning, I plan to stay in and stay cosy.

To Own the Future, Read Shakespeare | WIRED

I see what you nerds have done with AI image-creation software so far. Look at Midjourney’s “Best of” page. If you don’t know a lot about art but you know what you like, and what you like is large-breasted elf maidens, you are entering the best possible future.

After the end

I was doing some housekeeping on my website recently, tidying up some broken links, that kind of thing. I happened on the transcript and video for the talk I gave two years ago called “Sci-fi and Me.”

Sci-Fi & Me – Jeremy Keith – Stay Curious Café by beyond tellerrand

I really enjoyed preparing and giving that talk. It’s the kind of topic I’d love to speak/podcast about more.

Part of the structure of the talk involved me describing ten topics that might be encountered in the literature of science fiction. I describe the topic, mention some examples, and then choose one book as my pick for that topic.

For the topic of post-apocalypse stories, I chose Emily St. John Mandell’s Station Eleven. I love that book, and the equally excellent—though different—television series.

STATION ELEVEN Trailer (2021)

I’ve written in the past about why I love it:

Station Eleven describes a group of people in a post-pandemic world travelling around performing Shakespeare plays. At first I thought this was a ridiculous conceit. Then I realised that this was the whole point. We don’t have to watch Shakespeare to survive. But there’s a difference between surviving and living.

You’ve got a post-apocalyptic scenario where the pursuit of art helps giving meaning to life. That’s Station Eleven, but it also describes a film currently streaming on Netflix called Apocalypse Clown. Shakespeare’s been swapped for clowning, the apocalypse is set in Ireland, and the film is a comedy, but in a strange way, it tackles the same issue at the heart of Station Eleven: survival is insufficent.

APOCALYPSE CLOWN Official Trailer Ire/UK 2023

I really enjoyed Apocalypse Clown, mostly down to Natalie Palamides’s scene-stealing performance. It very much slipped by under the radar, unlike the recent Netflix production Leave The World Behind

Leave The World Behind | Final Trailer | Netflix

If you haven’t watched Leave The World Behind yet, stop reading please. Because I want to talk about the ending of the film.

SPOILERS

I never read the Rumaan Alam novel, but I thoroughly enjoyed this film. The mounting dread, the slow trickle of information, all good vibey stuff.

What I really liked was the way you can read the ending in two different ways.

On the large scale, we hear how everything that has unfolded is leading to the country tearing itself apart—something we see beginning to happen in the distance.

But on the smaller scale, we see people come together. When the final act was introduced as “The Last One” I thought we might be in for the typical trope of people turning on one another until there’s a final survivor. But instead we see people who have been mistrustful of one another come to help each other. It felt very true to the reality described in Rebecca Solnit’s excellent A Paradise Built In Hell.

The dichotomy between the large-scale pessimism and the smale-scale optimism rang true. It reminded me of The Situation. The COVID-19 pandemic was like a Rorscharch test that changed as you zoomed in and out:

I’ve noticed concentric circles of feelings tied to geography—positive in the centre, and very negative at the edges. What I mean is, if you look at what’s happening in your building and your street, it’s quite amazing how people are pulling together.

But once you look further than that, things turn increasingly sour. At the country level, incompetence and mismanagement seem to be the order of the day. And once you expand out to the whole world, who can blame you for feeling overwhelmed with despair?

But the world is made up of countries, and countries are made up of communities, and these communities are made up of people who are pulling together and helping one another.

Against Scale

Claire L. Evans has written a beautiful piece on the difference between growth and scalability:

Life is nonhierarchical, and it shirks top-down control. But scalability relies on hierarchy, on the isolation of elements stripped of history and context. It is predicated on the assumption that nature is little more than a raw material to be processed and commodified until it is spent. This is, of course, unsustainable — at any scale.
