Three panel comic. Panel 1: on the set of the Jerry Springer show, a man sits in a chair. Jerry signals off-stage and says, “we have with us: your ancestor who crawled out of the ocean 375 million years ago!” Panel 2: the live studio audience is booing. Panel 3: security attempts to break up a fight between the man on stage, and his ancestor, a tiktaalik.

Helpful points from @jburnmurdoch.ft.com here on what AI solving big maths problems might mean for the future of the maths community www.ft.com/content/c947...
Many mathematicians are leaning "bad". few days after the OpenAI Navier-Stokes
announcement, a group of 25 winners of mathematics' prestigious Fields Medal published a letter arguing that the goals of the AI companies and the human
mathematics community are fundamentally misaligned. Their core position is that although solving complex technical problems has historically accompanied expansions in our understanding, the former was only ever a proxy for the latter. A brute-forced solution without the
deliberation and painstaking accumulation of human knowledge along the way is the signal of expanded understanding without the actual expanded understanding.Another big question is what this all means for the incentives to share progress towards new discoveries. It's not hard to see how the threat of being scooped by AI could exert a chilling effect on the culture of sharing important incremental findings or promising new avenues, which has underpinned scientific progress for centuries. And for the Al labs themselves,
the backlash over the Navier-Stokes case may mean future Al-powered breakthroughs are kept under wraps. If AI is amazingly capable at turning new theories into findings, but stifles the development and sharing of those theories, there may be a bumpy road ahead.

GDT's reddit AMA spitting fire www.reddit.com/r/movies/com...
reddit comment: 

Hello! Did you intend the ending of Pan’s labyrinth to be real or in Ofelia’s mind?

Guillermo Del Toro's reply: 

My interpretation, and it's exclusively mine, is that it's real.

Because there's two things. One is what people call “The Shining Question.” The Shining Question is, Who opens the door for Jack to get out of the fridge? And Ofelia is in an attic with a guard outside her door, and she draws the door with the magic chalk, and she shows up in the labyrinth. So, the only way she could have gone into the labyrinth is the magic chalk. And the flower is real at the end. The flower that blooms in the dead tree. And the reason I think it’s real is because—and this is why I'm in favor of the human factor in art—I think that art does transform the world. You know?

Think about it for a second. One of the goals, with all this movement, is to make you believe that art is vulgar. That art is nothing special, and anybody can do art. That is like me telling you that I'm faster at running than Usain Bolt but I “run” in my motorcycle. Well, that's not the same. That’s not the same at all.

Art is important, and they want you to believe it isn't. It's part of the idea of control. The goal is not to have artificial intelligence. The goal is to foster natural stupidity. The goal is to foster you not looking for answers, and to trust yourself entirely to an engine. Look at the way we are dipping our toes into these things. We are starting to ask the machine, Is this true? For now, there's a correlation between reality and what the answers of the machine are. For now. But soon, we won't even investigate further. We will be told it's true. And if the machine is in the hands of somebody who should not be trusted, then your reality has been completely and utterly fucked. Because your intelligence ends at the question. You don't seek the answer. It's given to you.Q: You recently mentioned that AI creates 'semi-compelling screensavers' and that you'd 'rather die' than use it. As a filmmaker who relies heavily on practical effects and creature design, what do you think is the biggest thing lost when a computer generates an image instead of a human hand?

GDT:

The three quarters of the process that gave you the chance to think of the idea that people don't think about without that process. Meaning, AI can get you to the middle really fast, but there's a dialectic with the process that gets you to that top 10%. I'll give you an example with the Pale Man.

We sculpted it as an old man, with a face. And then I said, Let's take out the face. This happened because I saw a photo of a manta ray and the poster for Don Coscarelli’s Phantasm. That combination, which happened at two different times during a week or a month, are not permutations that are chemically part of an equation. They are alchemy. And then I said, Take out the face, and then I said, Let's put the eyes on the hands. This triangulation happens because I spent a month or two months living with the idea of this creature. And it's not linear.

AI is like a super-fast engine that makes semi-sentient permutations of things that are already done. Creation is things that have never been done. Coming to exist.

And the second thing is the loss of the apprenticeship that one has as an artist. You're never a master; you're always an apprentice. This is a kinship I have with, for example, Chris Nolan. When he showed me The Odyssey, there’s a scene when Matt Damon is floating in the stormy ocean and I asked him—because we were talking about practical effects, and how great it is and that we both always use a maquette or a model—and I asked him, How did you do it? He said, “We put him in a storm in the ocean.”

And you're gonna find that 30% of a great image occurs accidentally. You know, either a drop of water hits the lens, or the camera shakes. I remember when in 1993, '94, Jim…

My conclusions from the end of the post
Some observations #
The fact that a 17GB file can do all of this stuff on my home machines is a miracle. Once again, I’m delighted and amazed at how much progress local models have made this year. A year ago this would have been competitive with the best and most expensive of the proprietary models—today it can run on a capable laptop.

The only thing holding this back from being a daily driver is performance. It feels pretty slow on both the M5 Mac and the DGX Spark. That’s the catch with these dense (non-Mixture-of-Experts) models—they require a whole lot of memory bandwidth to perform well, and neither of the machines I have access to are top performers in that regard.

The most important thing about Qwen 3.8 27B is what it demonstrates. We can have an open weights general purpose model with a long context, effective tool calling, strong vision ability, and competent code generation, and we can fit the whole thing in just a 17GB file.

The models at this size continue to get better at an impressive rate. We don’t need to spend half a million dollars on datacenter-class hardware just to run a competent model.

A Google review of an audio store reads: "Worst phone interaction I've ever had in my entire life. I called to ask if they had an electrostatic headphone amp, I was informed that it was a waste of money to own electrostatic headphones. Then I tried to say that I know a lot about headphones and own many and that I am just looking for an amplifier, but then I was interrupted and told that I don't know anything. Wild!"A Google review of an audio store reads: "I normally have tremendous empathy for the mentally ill but not with this guy. He's abusive, slanderous and bizarrely demanding -- and that's if he likes you. Maybe he can still repair stuff but I wouldn't know; I walked away after the third time he screamed at me for asking a simple question and that's no exaggeration. Actual screaming. Just wild."
