The speaker describes population, technology, capital infrastructure, and human infrastructure as having grown together before the Industrial Revolution, after which capital infrastructure grew much faster than human population.

“growth that happened with the industrial revolution and so in some sense maybe you could say that's an example of like previously these things grew in tandem like more population more technology”

“more farms more houses etc like your sort of capital infrastructure and your like human infrastructure was like going up together but then we got the industrial revolution and they started to come apart and now like all the capital infrastructure was growing really fast compared to like the human population size”
