My point is that the old IT position of updating slowly is being attacked on multiple fronts. From users who want to use modern technology, from SaaS companies who are increasingly dropping support for old-but-not-that-old browsers, and from browser vendors who are all moving towards rapid release cycles. Even IE. I'm saying that the IT head, when it eventually gets to IE11 in 6 years and turns off automatic updates -- a feature that is on by default --, is going to find himself rather isolated and in my opinion a new crop of IT is going to form that's more nimble as a result.
