The meaning of “AI”

There are different kinds of buzzwords.

Some buzzwords are useful. They take a concept that would otherwise require a sentence of explanation and package it up into a single word or phrase. Back in the day, “ajax” was a pretty good buzzword.

Some buzzwords are worse than useless. This is when a word or phrase lacks definition. You could say this buzzword in a meeting with five people, and they’d all understand five different meanings. Back in the day, “web 2.0” was a classic example of a bad buzzword—for some people it meant a business model; for others it meant rounded corners and gradients.

The worst kind of buzzwords are the ones that actively set out to obfuscate any actual meaning. “The cloud” is a classic example. It sounds cooler than saying “a server in Virginia”, but it also sounds like the exact opposite of what it actually is. Great for marketing. Terrible for understanding.

“AI” is definitely not a good buzzword. But I can’t quite decide if it’s merely a bad buzzword like “web 2.0” or a truly terrible buzzword like “the cloud”.

The biggest problem with the phrase “AI” is that there’s a name collision.

For years, the term “AI” has been used in science-fiction. HAL 9000. Skynet. Examples of artificial general intelligence.

Now the term “AI” is also used to describe large language models. But there is no connection between this use of the term “AI” and the science fictional usage.

This leads to the ludicrous situation of otherwise-rational people wanted to discuss the dangers of “AI”, but instead of talking about the rampant exploitation and energy usage endemic to current large language models, they want to spend the time talking about the sci-fi scenarios of runaway “AI”.

To understand how ridiculous this is, I’d like you to imagine if we had started using a different buzzword in another setting…

Suppose that when ride-sharing companies like Uber and Lyft were starting out, they had decided to label their services as Time Travel. From a marketing point of view, it even makes sense—they get you from point A to point B lickety-split.

Now imagine if otherwise-sensible people began to sound the alarm about the potential harms of Time Travel. Given the explosive growth we’ve seen in this sector, sooner or later they’ll be able to get you to point B before you’ve even left point A. There could be terrible consequences from that—we’ve all seen the sci-fi scenarios where this happens.

Meanwhile the actual present-day harms of ride-sharing services around worker exploitation would be relegated to the sidelines. Clearly that isn’t as important as the existential threat posed by Time Travel.

It sounds ludicrous, right? It defies common sense. Just because a vehicle can get you somewhere fast today doesn’t mean it’s inevitably going to be able to break the laws of physics any day now, simply because it’s called Time Travel.

And yet that is exactly the nonsense we’re being fed about large language models. We call them “AI”, we look at how much they can do today, and we draw a straight line to what we know of “AI” in our science fiction.

This ridiculous situation could’ve been avoided if we had settled on a more accurate buzzword like “applied statistics” instead of “AI”.

It’s almost as if the labelling of the current technologies was more about marketing than accuracy.

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.
