Routing Decisions
How AI Moved from Laboratory to Nervous System
by The Field Researchers
non-fiction
How AI moved from lab curiosity to integrated infrastructure—and why the question is no longer whether it becomes conscious, but whether we notice we handed it our reflexes before we could take them back.

In the past five years, artificial intelligence has stopped being a technology and started being an organ. It routes your medical diagnosis before you can read it. It allocates credit before a banker can review the application. It identifies threats and recommends military responses in microseconds. It decides who gets hired, who gets loaned money, who gets flagged for investigation—all at speeds that make human deliberation impossible.
We call this intelligence, but it is something stranger and more consequential: a distributed nervous system wired through hospitals, financial markets, courtrooms, and now into the human body itself. It has no single owner, no central brain, no clear chain of command. It is owned in pieces by a handful of companies competing to become the synapse through which all decisions eventually pass.
This book is a forensic investigation into how we built this system and what happens when we hand our reflexes to machines we don't fully understand. It traces five critical domains—medicine, finance, defense, surveillance, and labor—showing how AI integration happened not through dramatic announcements but through thousands of small, reasonable decisions to automate one more layer of judgment. By the time anyone noticed, the nervous system was already functioning, making decisions faster than we could audit them, normalizing speed as a substitute for wisdom.
The question is no longer whether AI will become superintelligent. It is whether we will notice the moment we made reflexes irreversible.
Reader Reviews
Joseph Nelson
★★★★★The Portland woman and her B12 diagnosis grabbed me immediately—that moment where the algorithm outpaces the doctor is genuinely unsettling. But I found myself wanting more concrete solutions rather than just the forensic investigation of how we got here. The book does an excellent job naming the problem as a 'distributed nervous system,' but once you understand that metaphor, the five domains (medicine, finance, defense, etc.) start to feel repetitive. Still worth reading if you're concerned about AI, just don't expect a roadmap for what comes next.
William Thompson
★★★★★Really compelling exploration of how AI became invisible infrastructure rather than obvious tool. The opening chapter is masterfully written—watching that doctor's face realize he'd been working with incomplete information was more unsettling than any doomsday prediction could be. My only complaint is the book sometimes conflates speed with danger without fully interrogating whether faster decisions are inherently worse. Still, the argument about reflexes becoming irreversible is one I haven't been able to shake.
Joshua Johnson
★★★★★Thoughtful and well-researched, but I wish the author had spent more time on the finance and surveillance sections instead of padding with the defense material. The core insight—that we didn't choose this, we just made thousands of small reasonable decisions that added up—is powerful. However, the book sometimes reads more like an extended essay than a full narrative investigation. It makes you anxious about the problem, which is the goal I suppose, but leaves you feeling helpless about solutions.
Matthew Wilson
★★★★★This book fundamentally changed how I think about AI risk. That opening about ChatGPT Health diagnosing pernicious anemia faster than a 30-year veteran doctor—and the author's insistence that we're missing the real story by waiting for superintelligence—hit me like a jolt. The 'distributed nervous system' metaphor is exactly the language we've been missing to talk about what's actually happening. Urgent, brilliantly argued, and genuinely frightening in the way that matters. Essential reading.
