Merge Labs' Biological, Ultrasound Approach

A Note from James:

Data is oil. Data is the gold of this AI revolution. Imagine you have an AI that has all of everybody’s thoughts also—so it’s not just learning on tweets and texts, it’s learning on the 60,000 or so thoughts that 8 billion people think each day around the world.

This sounds like amazing science fiction and magic and everything that one could ever have dreamed of… or it could be the end of the world.

Episode Description:

In this solo episode, James breaks down a recent AI development that made him pause for the first time: OpenAI’s investment in a brain-computer interface startup called Merge Labs. He explains why data is the core asset in AI—and why the next frontier isn’t better chatbots, but higher-bandwidth access to human intent, attention, and ultimately thought.

James compares Merge Labs’ approach with Neuralink, then walks through the practical upsides: medical breakthroughs, hands-free control of devices, and AI-assisted cognition in everyday life. But he also explores the uncomfortable implications: privacy, influence, and the risk that “thought data” could become the most valuable—and most dangerous—resource on Earth.

What You’ll Learn:

• Recognize why “data is oil” is still the most important frame for AI power
• Understand what brain-computer interfaces are, and how they differ across companies
• Think through real use cases (medical, device control, communication) before the hype takes over
• Identify the privacy line: what “training on your thoughts” could actually mean in practice
• Pressure-test your own optimism about AI by asking: “Once data is shared, can it be unshared?”
