Anyone interested in this topic should pick up a copy of Carlota Perez's Technological Revolutions and Financial Capital. It speaks more specifically about the last 5 revolutions, beginning with the Industrial Revolution, and provides a framework for understanding the relationship between tech revolutions and finance. Just a fantastic read.
Don't just take my word for it though. Here is Fred Wilson saying the same: http://avc.com/2015/02/the-carlota-perez-framework/
