We present a typology of traps to avoid: 1. Believing that AI systems are minds 2. Believing that AI systems are theories 3. Believing that cognitive science can be automated. Learn to recognise and avoid these traps. Failure to avoid leads to numerous problems.
Table 1: Typology of traps, what goes wrong if not avoided, and how the traps can be avoided. Note that all traps in a sense constitute category errors (Ryle & Tanney, 2009) and the success-to-truth inference (Guest & Martin, 2023) is an important driver in most, if not all, of the traps.

On this day 12 and a half years ago I saw the coolest ever iceberg. Never seen one like it since. Fellsfjara, Jökulsárlón, #Iceland
A six-foot (ish) high turquoise iceberg with a small friend on a black sand beach. Grey rainy day with some of the turquoise reflected in the blank sand, and long exposure smooth waves breaking.

A huge part of surgery is pain mitigation and the relief of suffering. It's called care. It's called humanity. It's called empathy. it's called stewardship. These AI asshats have lost all of that, and they should be suffering for it, not us.

More broadly, the so-called fixes being pushed out, such as age verification, punish the consumer instead of forcing the companies to do better. The whole model of how these things are legislated is backwards. Make the companies fix it, not their users, who are already trapped in a dystopia.

That's half of why I didn't sign on to the Anthropic authors suit. The other half is that there are a thousand other companies doing the same, so what symbolism the payout may have is close to meaningless. This problem is not ours to solve; it requires leadership, something sorely lacking nowadays.

AP Stylebook warns against anthropomorphizing AI systems: “Avoid language that gives them human characteristics… Instead, explain what a system does, how well it performs, who built it and who could be affected by it.”
APStylebook @APStylebook

Artificial intelligence systems do not think, feel, want or understand. Avoid language that gives them human characteristics. This is called anthropomorphizing, when we ascribe human traits, emotions or behaviors to non-human things, such as animals or inanimate objects.
Instead, explain what a system does, how well it performs, who built it and who could be affected by it.

The Facial Expressions of Tethys by artist Julius von Bismarck. A suspended high-sea buoy that moves in real time. Sensors on a twin buoy out in the Atlantic Ocean send live satellite data to motors inside the museum. This makes the indoor buoy copy the exact, real-time movements of the ocean waves.

As with Pandora's Box (in the Greek myth it's actually a jar), the Fall is just a way to give the power of knowledge to men while making women take the blame for the problems it brings.

If you have time, go to the Kunsthaus and ask to see the massive collection of Dürer etchings in the library. It's an incredible resource. So special perhaps I shouldn't be advertising it.

Let's talk about the bristlemouths, 13 species of bioluminescent deep-dwelling ocean fish in genus Cyclothone. There are a lot of them. Like, a lot. Specifically, our best guess is there are a million billion (1E15) bristlemouths on Earth. Making them the most populous vertebrate on the planet.
A xenomorph looking fish with dark slightly sparkly skin and an oversized lower jaw packed with sharp, needle-like teeth.

Today in 1982, in a posting made to a Carnegie Mellon bulletin board, Professor Scott Fahlman proposes the first known use of emoticons While they became famous in 1980s & beyond, their origin remained unknown until 2002, when the original message was retrieved from backup tape. Original post

When I was in Helsinki I stopped by what I thought was the furniture outlet for Alvar Aalto, but that turned out to be his old studio. The kind folks there accepted me, a huge fan, and showed me original drawings of most of his incredible commissions. What a day!

a very effective presentation of androgen insensitivity (& indirectly, non-cell-autonomy, a core principle in development & evolution of multicellularity) in many situations, the cells in your body get external signals that tell them who they are & what they do, rather than knowing it internally

This Abbott and Costello routine probably used 100 gallons of water and could power a household for a month. And again, the interface for AI is all wrong. It should not be programmed to give definitive answers. The model for this case should be the Librarian in Neil Stevenson’s Snowcrash.

I wonder if this might be a turning point. I'd like to think so. Because this declaration speaks to so much about the problem with AI in such contexts. If it can be of help in, say, drug discovery, that's fine. But it's precisely because maths doesn't have those stakes that the message is powerful..
