What we have done at Politico has been relevant to the conversation about where journalism is going. But by no means do I believe that we have cracked the code on the awesome challenges facing our profession. Both of the time-travel flights I sketched above contain elements of my real-life perspective. I am bullish on the future of journalism, and think the pessimists are not just a drag, but in their own way, naïve. I also think that complacency is a curse, and that constant innovation is indeed the only remedy.

So there is no rest for the weary, and no time to worry much about anxiety dreams. I am wide awake now.
