"Until a few years ago, the topics in my Ph.D. were unfashionable, but they are very popular today"
About this Quote
The subtext is a critique of gatekeeping disguised as mild autobiography. A Ph.D. topic shouldn’t be “popular” in the way a sneaker drop is popular, yet that’s precisely the ecosystem he’s pointing at. Mandelbrot spent years on objects and patterns that looked messy, irregular, even suspiciously non-rigorous to mid-century mathematical taste. Fractals, scaling laws, roughness: these were hard to classify, harder to publish, and easy to dismiss as curiosities.
Then the world changed. Computing power made his visual intuitions legible; chaos theory and complex systems made “mess” a respectable subject; finance, physics, and biology all needed tools for irregularity. Popularity arrives when a community finds uses, metaphors, and measurements.
The intent isn’t just “I was right.” It’s sharper: novelty often looks like error until the culture invents the language to praise it. Mandelbrot’s understatement doubles as a warning to anyone mistaking consensus for rigor.
