In this episode of Crazy Wisdom, Stewart Alsop talks with Will Bickford about the future of human intelligence, the exocortex, and the role of software as an extension of our minds. Will shares his thinking on brain-computer interfaces, PHEXT (a plain text protocol for structured data), and how high-dimensional formats could help us reframe the way we collaborate and think. They explore the abstraction layers of code and consciousness, and why Will believes that better tools for thought are not just about productivity, but about expanding the boundaries of what it means to be human.

Key Insights

1. The exocortex is already here, just not evenly distributed. Will frames the exocortex not as a distant sci-fi future, but as something emerging right now in the form of external software systems that augment our thinking. He suggests that tools like plain text editors, command-line interfaces, and version control systems are early prototypes of this distributed cognitive architecture—ways we already extend our minds beyond the biological brain.
2. Brain-computer interfaces don’t need to be invasive to be powerful. Rather than focusing on neural implants, Will emphasizes software interfaces as the true terrain of BCIs. The bridge between brain and computer can be as simple—and profound—as the protocols we use to interact with machines. What matters is not tapping into neurons directly, but creating systems that think with us, where interface becomes cognition.
3. PHEXT is a way to compress meaning while remaining readable. At the heart of Will’s work is PHEXT, a plain text format that embeds high-dimensional structure into simple syntax. It’s designed to let software interoperate through shared, human-readable representations of structured data—stripping away unnecessary complexity while still allowing for rich expressiveness. It's not just a format, but a philosophy of communication between systems and people.
4. Software abstraction is about compression, not complexity. Will pushes back against the idea that abstraction means obfuscation. Instead, he sees abstraction as a way to compress vast domains of meaning into manageable forms. Good abstractions reveal rather than conceal—they help you see more with less. In this view, the challenge is not just to build new software, but to compress new layers of insight into form.
5. Text is still the most powerful interface we have. Despite decades of graphical interfaces, Will argues that plain text remains the highest-bandwidth cognitive tool. Text allows for versioning, diffing, grepping—it plugs directly into the brain's symbolic machinery. It's composable, hackable, and lends itself naturally to abstraction. Rather than moving away from text, the future might involve making text higher-dimensional and more semantically rich.
6. The future of thinking is collaborative, not just computational. One recurring theme is that intelligence doesn’t emerge in isolation—it’s distributed. Will sees the exocortex as something inherently social: a space where people, software, and ideas co-think. This means building interfaces not just for solo users, but for networked groups of minds working through shared representations.
7. Designing better protocols is designing better minds. Will’s vision is protocol-first. He sees the structure of communication—between apps, between people, between thoughts—as the foundation of intelligence itself. By designing protocols like PHEXT that align with how we actually think, we can build software that doesn’t just respond to us, but participates in our thought processes.
