AI Summary
5 min read🎙️ The Voices & The Context
The Format: This is a narrative-driven podcast crossover episode, structured as an interview between host Andy Mills and reporter Gregory Warner. It feels like a science documentary mixed with a late-night campfire story—equal parts awe and "ew, gross."
The Key Players:
- Andy Mills: The host, acting as the curious everyman. He asks the questions you're thinking ("Does it smell?" "Is this cruel?").
- Gregory Warner: The reporter from The Last Invention series. He's the guide into the weird world of biological computing, delivering the story with palpable fascination and just the right amount of horror.
- Han Wang Chung: The mad-scientist CEO of Cortical Labs. He built a computer powered by living human brain cells.
- Minas Liarocapas: A roboticist who wants to put those brain cells into robot hands and skin.
The Vibe: Fascinating and slightly nauseating. It's a mix of genuine scientific wonder, dark humor, and existential dread. The tone is conversational and playful, but the implications are deeply serious.

What if the next great leap in computing wasn't made of silicon — but of living human brain cells? Reporter Greg Warner takes us inside the lab of Hon Weng Chong, an Australian computer engineer who has built a biological computer: a device that houses actual human neurons in a petri dish, teaches them to play Pong using reward and punishment, and is now being sold to medical researchers, crypto gamers, and roboticists with very big dreams. Along the way, Andy and Greg dig into what these cells might actually feel, why the path to artificial general intelligence might run through a robot's skin rather than its brain, and what it would mean to one day stick a chip of pre-programmed neurons back into a human head. It's weird, it's a little smelly, and it might be the future.
