The Inversion

For most of human history, the most valuable place to be was the middle.

Here’s what I mean. In the 1920s, AT&T employed hundreds of thousands of switchboard operators. Their entire job was to sit at the centre of the network and be the intelligence: know who was calling, know who to connect them to, route the signal manually with their hands. The technology existed to carry the call. The human was the part that made it make sense.

Then automated switching happened. The intelligence moved from the humans into the machine. The operators didn’t disappear — they moved to the edge. Troubleshooting. Customer service. Designing better systems. The work shifted from being the connection to building and maintaining the thing that connects.

That’s the inversion. And it’s happening again, right now, to almost every knowledge job.

For the last 100 years, most of what organisations paid people to do was coordinate. Managers routed information between teams. Analysts translated data into decisions. Project managers tracked dependencies and unblocked things. Middle layers existed to carry signal through a system that couldn’t carry it any other way. The humans were the intelligence glue.

AI changes what the glue is made of.

The model sits in the middle now. It holds context across the whole system. It routes tasks, summarises information, connects the person asking a question to the answer that already exists somewhere else in the organisation. It does in milliseconds what used to take three meetings and a follow-up email.

Which means the humans move to the edge.

Not out. To the edge.

And the edge is actually the more interesting place to be. The people on the edge are the ones who decide what the system should do, catch what it gets wrong, and redesign it when the world changes. They’re not passing messages anymore. They’re building the thing that passes messages. They’re not coordinating work. They’re designing the coordination itself.

This is what Dorsey means when he says “the intelligence lives in the system, the people are on the edge.” It’s not a cost-cutting line. It’s a description of where the real work has moved.

The question for anyone building a team or a company right now isn’t “how do I protect the middle?” It’s “what does it look like when my people are genuinely at the edge?”

That’s a harder question. It’s also the right one.
