“the old cast iron buildings died out. I'm not really sure whether the new skyscrapers killed them, or the new esthetics”
After 40 years of using iron as a main component in construction, architects and engineers started to find the flaws in this material. In the case of Chicago, where there was a need to start over (construction and designing wise) i think that what let the use of iron die was the new esthetics. Maybe after the terrible fire people felt right erasing the past and starting from scratch. This gave them the chance to develop intelectually surpassing old boundaries, and as a result the new skyscrapers appeared.
