We estimate that there are perhaps 20,000 prehistoric hunter-gatherers frozen up in those glaciers. Now, if they simply thaw and wander around, it's not a problem, but if they find a leader - a Captain Caveman, if you will - we'll be facing an even more serious problem.

A lot of media that that I want to consume, I don't want to have to own forever and ever. It's not like real estate.

The reality is that there is an enormous value to gut-check instinctive decision-making in the world that is not hampered by reams and reams of research and complexity.

My career as a magazine writer was largely prefaced on the idea of curiosity, to go on adventures and weasel my way into the lives of people that I admire.

I'm an older, wall-eyed, overweight, tweedy writer who has been lucky enough to be asked to play various iterations of himself in a certain realm of popular cultutre. That gives me great joy and excitement, but I don't go to the media saying, "And I'm also the world's greatest actor."

I was always fascinated with the way that things pop on the Internet - the ways you build communities and create little stories and ideas that people play around with and send back to you.
