Trump is a master at wielding attention. He’s been owning news cycles and squatting in Americans’ minds for much of the last decade. And for his second term he has an ally in Elon Musk, a man with a similar uncanny skill set.

Trump and Musk seem to have figured out something about how attention works in our fragmented media age — and how to use it for political and cultural power — that Democrats simply haven’t. So what is it? What do they understand about attention that their opponents don’t?

Chris Hayes is the host of MSNBC’s “All In,” and has written a forthcoming book, “The Sirens' Call: How Attention Became the World's Most Endangered Resource.” And he’s a brilliant thinker on how our modern attention economy works and what it’s doing to our politics.

We discuss what Hayes sees as a revolution happening to our attention, which he compares to the Industrial Revolution in its scale and impact; why the old rules about attention in politics no longer apply; the key insight Trump had about attention that fueled his rise; why Musk didn’t really overpay for Twitter; and how Democrats can compete in this new attentional world.
