 I think the central issue confronting higher education is finding its path to scale. Digital goes to scale every time. Now what's interesting about that is digital doesn't drive out heterogeneity. In fact it actually enables lots more heterogeneity. Look at Amazon. Amazon has built an extraordinary retail machine where they sell and make customers very happy but they've enabled Bob's you know fly and tackle bait shop to go on to Amazon and sell uniquely and let Amazon handle the credit cards in the website and those things. Things go to scale and I think higher ed we've built our entire multi-millennia structure out of being very independent and to the extent that we don't figure out how to go to scale and take advantage of the favorable economics. I mean things go to scale digitally not because it's fun but because it's economically the sweet spot to get there. So I do believe that strategies to compete and deal with this we've historically focused on great independence amongst institutions. More recently we've done lots of dependence on a few key vendors or a few key things. I think we've got to get much smarter at intentional interdependence amongst colleges and universities as a means of confronting the central challenge of our era and that is a path to scale.
