The basic financial infrastructure that today’s economy runs on, corporate bonds, public equity markets, institutional underwriting, cross-border capital flows, credit analysis, even the concept of a “balance sheet,” all of it was built to finance railroads. Railroads didn’t just change transportation. They changed money. They were the platform layer underneath everything else.

Morgan invented what we now call private equity restructuring, distressed debt investing, and activist board governance. He didn’t create these concepts from a textbook. He created them because the railroad industry was a catastrophe and someone had to clean it up, and it turned out that cleaning up catastrophes was the most profitable business of all.

I keep thinking about this when I look at AI. The question isn’t just “who builds the best model?” The question is: when the shakeout comes (and if the railroad precedent means anything, a shakeout will come), who will be the Morgan? Who’s sitting on the sidelines with enough capital and enough patience to buy the wreckage and reorganize it?

I don’t know who wins the AI race. Nobody does. If you’d asked someone in 1865 which railroad company would dominate American transportation in 1920, they would have given you a confident answer that was wrong. I’m pretty sure we’re in 1865 right now.
