In this video we explore Predictive Coding – a biologically plausible alternative to the backpropagation algorithm, deriving it from first principles.
Predictive coding and Hebbian learning are interconnected learning mechanisms where Hebbian learning rules are used to implement the brain's predictive coding framework. Predictive coding models the brain as a hierarchical system that minimizes prediction errors by sending top-down predictions and bottom-up error signals, while Hebbian learning, often simplified as "neurons that fire together, wire together," provides a biologically plausible way to update the network's weights to improve predictions over time.

Priscilla Chan and Mark Zuckerberg on Curing All Disease
We sat down with Dr. Priscilla Chan and Mark Zuckerberg, co-founders of the Chan Zuckerberg Initiative, to discuss their ambitious plan to cure, prevent, and manage all disease by the end of the century.
This is a use of Rerun that I haven't seen before!
This is pretty fascinating!!!
Typically people use Rerun to visualize robotics data - if I'm following along correctly... what's fascinating here is that Adam for his master's thesis is using Rerun to visualize Agent (like ... software / LLM Agent) state.
Interesting use of Rerun!
Is this useful for you?
To answer you directly, a smaller SOTA reasoning model with a table of facts can rederive relationships given more time than a bigger model which encoded those relationships implicitly.
In LLMs, we will have bigger weights vs test-time compute tradeoffs. A smaller model can get "there" but it will take longer.
The exact quote is: "I foresee the day where AI become so good at making a deep fake that the people who believed fake news as true will no longer think their fake news is true because they'll think their fake news was faked by AI."

How Inflation Makes the Rich Richer
When David Eagleman was eight years old, he fell off a roof and kept on falling. Or so it seemed at the time. His family was living outside Albuquerque, in the foothills of the Sandia Mountains. There were only a few other houses around, scattered among the bunchgrass and the cholla cactus, and a new construction site was the Eagleman boys’ idea of a perfect playground. David and his older brother, Joel, had ridden their dirt bikes to a half-finished adobe house about a quarter of a mile away. When they’d explored the rooms below, David scrambled up a wooden ladder to the roof. He stood there for a few minutes taking in the view—west across desert and subdivision to the city rising in the distance—then walked over the newly laid tar paper to a ledge above the living room. “It looked stiff,” he told me recently. “So I stepped onto the edge of it.”
In the years since, Eagleman has collected hundreds of stories like his, and they almost all share the same quality: in life-threatening situations, time seems to slow down. He remembers the feeling clearly, he says. His body stumbles forward as the tar paper tears free at his feet. His hands stretch toward the ledge, but it’s out of reach. The brick floor floats upward—some shiny nails are scattered across it—as his body rotates weightlessly above the ground. It’s a moment of absolute calm and eerie mental acuity. But the thing he remembers best is the thought that struck him in midair: this must be how Alice felt when she was tumbling down the rabbit hole.
I don't understand such analysis when there are opposing "blob" forces trying to push the world into worse state. Forget about people dying in earthquakes, consider current wars, we are using resources (human, capital, tech) to destroy resources (uprooting human lives, destroying buildings, blowing up infrastructure) while those very resources could be used to create more resources which solve problems and create wealth. World is not a closed system, there are forces operating which for whatever reasons are not aligned for humanity's flourishing.
Marc Andreessen has made statements that align with the idea that abundant capital can lead to poor decision-making or a lack of discipline among founders. The core of his perspective emphasizes the importance of resourcefulness, persistence, and an intense focus on building the business over optimizing for fundraising.
"Too much capital breeds sloppy execution": While this specific quote might be from another source, it reflects a sentiment consistent with Andreessen's philosophy, which values the discipline forced by resource constraints (bootstrapping) in the early stages of a startup.
Wasn't there a whole movement of Lean startups? What happened to that?
