One of the hallmarks of 2025 in AI analysis, was discussion and debate around the AI boom relative to the AI bubble. These days I gravitate towards original macro analysis around the AI Infrastructure buildout, economics and what history says. I’ve been a (secret) fan of Howe Wang’s writing for a while but was blown away by his November piece Early in AI, Late in the Trade. I’m obsessed with this topic of how does the AI bubble compare with history? Not just Railway, but all of them?
