EP33 - Micro LLMs: Putting a Supercomputer in Your Pocket

AI assistants feel like they're connected to a giant brain in the cloud, but increasingly, they live right inside your phone, working instantly and offline. How is it possible to shrink a supercomputer's worth of intelligence onto a tiny chip? This is the story of Micro LLMs, and how the future of AI might not be in the cloud, but in the palm of your hand.

EP32 - The Rise of Humanoid Robots: AI Gets a Body

We see viral videos of humanoid robots that walk, run, and work with an eerie, lifelike grace that feels like science fiction. But beyond the complex code and powerful motors, what fundamental truth allows a two-hundred-pound machine to master the simple, impossible art of not falling over? This episode deconstructs the humanoid robot to reveal why the key to its future lies not in its own design, but in ours.

EP31 - Synthetic Media: When Seeing Is No Longer Believing

We see a famous actor in a viral video or hear a politician say something they never uttered, and it looks and sounds perfectly real. We might call it a deepfake, but that simple name hides a profound technological duel. This is the story of how machines learned to replicate reality by competing against each other, and what that means for a world where seeing is no longer believing.

EP30 - The Electric Dream: Neuromorphic Computing and the Brain on a Chip

We marvel at AI that can write poetry and paint masterpieces, assuming it "thinks" like us. But what if our computers, even the ones running AI, are built on a fundamentally different, and far less efficient, blueprint than our own brains? This episode opens the black box of neuromorphic computing to reveal how building a brain on a chip could solve the greatest crisis facing artificial intelligence.

EP25 - The Glimmer in the Deep: Finding the Physical Internet Under the Sea

We think of the internet as the Cloud—ethereal, wireless, and everywhere. But 99% of the data that connects our world travels not through the air, but through a hidden network of glass cables laid across the pitch-black, crushing depths of the ocean floor. This is the story of the physical internet, and how a simple principle of light makes our instant, global lives possible.

EP24 - The Chorus of Light: How Self-Driving Cars Actually See

A self-driving car navigates a chaotic city street with a calm, superhuman precision that feels like magic. We think of it as a car with better eyes, but the truth is far stranger and more profound. How does a machine perceive the world in three dimensions, and what can its chorus of secret senses teach us about the nature of reality itself?

EP21 - The Electric Skin: First Principles of the Modern Touchscreen

We touch, tap, and swipe on glass screens dozens, even hundreds of times a day, manipulating the digital world with our fingertips. It feels like magic, a seamless connection between our intent and the machine. But the glass isn’t sensing pressure; it’s sensing something far more fundamental about what we are, and the secret lies in a silent, invisible orchestra of electricity.
