Carl's speech challenged us to help influence the changes within the profession which is moving forward towards the tipping point of the new AIA. He wants to inspire a new generation of architects who will help define us as a profession in a new and innovative way and ultimately help bring value to our world. 
I paraphrase: 
Architects are being asked to come up with solutions to climate change, health and well being, and workplace diversity... If not architects than who will design our new world?
