Title: Big Mirrors, Bayesian Evangelists and the Public: How Advances in Mirror Technology, detectors, databases, machine learning and crowd-sourcing are driving Astronomy into the future Abstract: A plethora of technology advances over the past 40+ years have coalesced to drive ground-based Astronomy into directions barely imagined a generation ago. Advances in everything from materials science to information technology have made this possible. I will go through the historical record in some of these technologies and show how radically things have changed for the workaday Astronomer today and perhaps see where these technologies are taking us.
