The attached chart argues that the AI boom has become the largest investment surge in history, comparing it with canal mania, railway mania, the Roaring 20s and the dot-com era.
The main message is not just that AI investment is large today, but that on a normalized, log-scale view it has outpaced several famous historical booms at a similar point after the trough. The visual is meant to frame AI as a capital cycle on the scale of major past manias.
