I spent hours with Paul Baran over the years, and I never quite got used to his mind.
He asked questions you wouldn’t expect. Not provocative questions, not contrarian ones — just questions that arrived from a slightly different angle than you’d prepared for. And the strange thing was the aftermath. You’d hear the question, feel briefly disoriented, and then — almost immediately — think: of course. Now I understand.
Paul invented the Telebit Trailblazer modem. If you were around in that era you remember what modems were: devices that negotiated a fixed speed and held it. The whole industry operated that way. Speed was a spec, a number on the box, a ceiling you bumped against.
Paul looked at the same problem and saw something different. He didn’t ask how fast a modem could go. He asked what a specific telephone circuit was actually capable of — this wire, right now, in these conditions. The Trailblazer was adaptive. It listened to the line before it decided anything. It milked transfer speeds out of circuits that conventional modems had already given up on.
That’s not a new technique. That’s a new question.
I’ve thought about Paul a lot since then, trying to locate the thing that made his mind work differently. I don’t have a single moment to point to. No whiteboard revelation, no conversation I can replay. Just the accumulated residue of hours in the room with someone who seemed to be operating on different premises than everyone else — asking the question that preceded the question the rest of us were answering.
Morgan Housel quotes Visa founder Dee Hock in Same As Ever: “New ways of looking at things create much greater innovation than new ways of doing them.”
I read that and thought of Paul immediately. What I took from all those hours with him wasn’t a method or a framework. It was simpler and harder than that — a habit of suspicion toward the assumptions already in the room. The ones everyone had agreed to without quite deciding to. The fixed speeds no one was questioning.
I still hear his voice when I catch myself accepting an assumption. Is it, though?
