The Godfather of AI Claims a Multi-modal AI had a Subjective Experience

The Prism, the Pointing Arm, and What Hinton Got Right (and Wrong).

In a recent talk, Geoffrey Hinton offered a thought experiment he thinks settles a long-running argument about machine consciousness. The setup is simple. You have a multimodal chatbot with a camera, a robot arm, and language. You place an object in front of it and ask it to point. It points. You then sneak a prism in front of the camera lens. You ask again. It points off to one side, because the prism has bent the light. You tell it about the prism. The chatbot replies: “Oh, I see. The prism bent the light. The object is actually straight in front of me, but I had the subjective experience that it was off to one side.”

Hinton’s claim is that the chatbot, in saying this, is using the phrase “subjective experience” exactly the way you and I use it. Therefore the chatbot had a subjective experience. Therefore the line we draw between human and machine experience is, in his words, rubbish.

I had to think about this, because Hinton is that guy, and the example is doing more work than it first appears. But I also want to say where I think the argument is weaker than it is being sold, and where I think it is stronger.

Creating an Index for a Technical Book using AI

How I used Claude to build a 5,000-entry index for a 600 page technology book without going crazy. The hard part of indexing is not inserting tags, but you will want to automate the boring mechanical labour.

I have spent the last couple of years writing a book about Embedded AI for No Starch Press (NSP). It has been three times the amount of work that I was expecting. The editing process feels never ending and by the end you will never want to read your book again. It does make for a better book though, and I am now an advocate for having an external editor.

One of the more tedious aspects of putting together a book is index tagging. The publisher can index for you, but it will cost around $4 per page and this comes out of your royalties. Not many people get rich writing a book, but there is no point throwing away hard earned royalties! There are lots of things you have to do manually when creating a book (like writing), but this feels like a task that a Large Language Model (LLM) should be good at.

NSP expects the finished index to weigh in at 5 to 8 percent of the manuscript word count, so for a 100,000-word book you are building something in the range of 5,000 to 8,000 words. This is a substantial document in its own right.

Your Brain Has a Real Estate Problem, and Dreams Might Be the Solution

What a strange theory about REM sleep tells us about building AI that doesn’t quietly fall apart

Put a blindfold on a sighted adult and stick them in an fMRI scanner. Get them to feel some textured surfaces with their fingers. Then watch what happens in their visual cortex, the part of the brain that is supposed to be doing absolutely nothing in the dark. It lights up. Not after weeks, not after days, but after about forty-five minutes.

That finding, which has been replicated in various forms since the early 2000s, is one of the more unsettling results in modern neuroscience. The visual cortex is not a quiet, dormant region waiting patiently for the lights to come back on. The moment you stop using it for vision, the neighbours start moving in. Touch first, then hearing. Within an hour, real estate that was supposed to be reserved for processing photons is being repurposed for something else entirely.

This raises an obvious and slightly alarming question. If your visual cortex starts getting taken over within an hour of going dark, what happens every single night when you close your eyes for eight hours?

A neuroscientist named David Eagleman thinks he has the answer, and it is one of the more interesting hypotheses about why we dream that has come along in a while. He calls it the defensive activation theory, and once you understand it, you start seeing the same pattern everywhere, including in some surprisingly broken corners of how we currently build AI.

A chip that controls a balancing propeller on seven microwatts

Every battery-powered device you own has a quiet energy hog in it that nobody talks about. It is not the processor, it is not the radio, and it is not the screen. It is the analog-to-digital converter, the small piece of circuitry that translates the messy real world into the clean ones and zeros a computer can think about. For thirty years it has been the line item that decides how long your hearing aid, your pacemaker, or your soil sensor lasts on a battery.

In March 2026, a team at the University of Michigan published a result that quietly removes that converter from the picture for a specific class of problems. Their bismuth selenide memristor runs a closed-loop control task at about seven microwatts, roughly a millionth of what a household LED bulb pulls. The chip does not run code in any conventional sense. The physics does the arithmetic, and the answer drives the motor directly.

In this episode, we walk through what the device actually is, why removing the converter changes the energy budget by orders of magnitude, and which products land first when microwatt-class intelligence becomes buildable. We talk about hearing aids, implants, environmental sensors, and the small drones that have been waiting for this kind of result for a decade. We also talk about what this chip cannot do, because the press releases tend to skip that part. It will not run a language model. It will not recognise your face. It will run the reflexes underneath all of that, and the case for why those reflexes matter more than the cortex gets credit for is the through-line of the episode. #embeddedAI #podcast

Spot the Robot Can Reason, but it can’t hold a can of soda

Boston Dynamics and Google DeepMind announced last month that Spot is now running Gemini Robotics-ER 1.6, a high-level embodied reasoning model. The headline is that Spot has been taught to reason. The commercial pitch is industrial inspection: wandering around a facility, reading gauges, spotting spills, deciding what to do when something looks wrong. So far, so good.

Buried in the demo video is a small failure that says more about the architecture than the press release does. Asked to recycle cans in the living room, Spot picks one up sideways. If there is any liquid left in the can, it ends up on the carpet. The problem is using a language model to solve something handled by other more primitive layers in the organic world.

Why 95% of AI Deployments Fail

MIT’s August 2025 study of 300 enterprise generative AI deployments found that 95% produced no measurable P&L impact. Gartner forecasts that more than 40% of agentic AI projects will be cancelled by 2027. McKinsey’s State of AI 2025 identifies workflow redesign as the single strongest correlate with EBIT impact, yet only 21% of organisations have redesigned any workflows. The data converges on a structural conclusion: enterprise AI is failing because the operational substrate is inadequate, not because the models are. This episode examines the process-readiness gap, the misallocation pattern that concentrates investment in low-ROI front-office applications, and what the 5% of high performers do differently. It is an architectural argument, not a change-management one: AI is a linear amplifier acting on a pre-existing process, and the sign of the output depends on the sign of the input.

Why ARC’s $2M Bet Against Priors Is the Wrong Bet for Embedded AI

ARC says intelligence emerges from learning when priors are minimised. Vertebrates disagree and have spent 500 million years proving the opposite.

The ARC Prize is a public competition with $2 million on the table, run by François Chollet (creator of Keras) and Mike Knoop (co-founder of Zapier). The premise is that current AI benchmarks measure what a model already knows, not how well it learns. Their fix is ARC-AGI, a series of reasoning tasks that are easy for humans and, so far, brutal for machines. Frontier models score below 4% on ARC-AGI-2.

The newest version, ARC-AGI-3, swaps static puzzles for interactive game environments where the agent has to figure out the rules by playing, with no instructions and no pre-loaded domain knowledge. Humans score 100%. AI scores under 1%. The gap demonstrates the point. Behind the gap is a philosophy about what intelligence is and where it comes from, and that philosophy is where the Primal Layers framework and ARC differ.
