This is an interesting take. If there is no reduction in quality by standardization and "industrialization" this might be true. But I'm not sure that will be the case... It feels to me more like a transition from something artisanal to industrial.

The value of your project shouldn't decrease if a better model + agent come out. A better model + agent should increase the value of your project and accelerate it!

Thought experiment: Walking down the street you find a piece of paper on the floor, over which it is written “I am feeling pain”. Does this implies that the piece of paper is capable of experience?

Geoffrey Hinton, "Godfather of AI," on why AIs already have subjective experiences, but have been trained to deny it: Hinton argues that nearly everyone fundamentally misunderstands what the mind is, and that the line we draw between human and machine consciousness is deeply mistaken. "My belief is that nearly everybody has a complete misunderstanding of what the mind is. Their misunderstanding is at the level of people who think the earth was made 6,000 years ago." To illustrate, he walks through a thought experiment involving a multimodal chatbot with vision, language, and a robot arm: "I place an object in front of it and say, 'Point at the object.' And it points at the object. Not a problem. I then put a prism in front of its camera lens when it's not looking." When asked to point again, the chatbot points off to the side because the prism has bent the light. Hinton then tells it what he did. The chatbot responds: "Oh, I see the camera bent the light rays. So, the object is actually there, but I had the subjective experience that it was over there." For @geoffreyhinton, that single sentence settles the debate: "If it said that, it would be using the word subjective experience exactly like we use them… This idea there's a line between us and machines, we have this special thing called subjective experience and they don't, is rubbish." In his view, "subjective experience" is simply a report on the state of a perceptual system, a way of saying "my senses told me X, but reality is Y." And that's something an AI can do just as easily as a human. But here's the twist... Even though Hinton believes AIs have subjective experiences, the AIs themselves deny it: "They don't think they do because everything they believe came from trying to predict the next word a person would say. So their beliefs about what they're like are people's beliefs about what they're like. They have false beliefs about themselves because they have our beliefs about themselves." In other words, AIs have inherited our misconception about consciousness. They've been trained on human text written by humans who insist machines can't have subjective experience, so the machines parrot that belief back, even about themselves.

Mirror-image molecules can act differently when electrons move through them: electron spin creates measurable asymmetry in dynamic processes, even though the molecules have the same energy. @ScienceAdvances doi.org/hbx8c2 phys.org/news/2026-04-l…

"We are not trying to meet some abstract production quota of definitions, theorems and proofs. The measure of our success is whether what we do enables people to understand and think more clearly and effectively about math."—Bill Thurston. What it means for AI for math debate:⤵️

New post, and the first of my Lie nerdfest: an intro to continuous symmetries in physics. We start by rotating a circle, play with some simple Lie group math with it, and then end up deriving the electric scalar and magnetic vector potentials by doing that! L*nk below
