Annalee Newitz is pretty much nerd royalty. They are the author of the novels The Future of Another Timeline and Autonomous, which won the Lambda Literary Award. As a science journalist, their work appears regularly in the New York Times and New Scientist, as well as in The Washington Post, Slate, Popular Science, Ars Technica, The New Yorker, and The Atlantic. They co-host the Hugo Award-winning podcast Our Opinions Are Correct, founded io9, and served as the editor-in-chief of Gizmodo. Annalee joined Adrian and Laura to dish about their most recent book, Four Lost Cities: A Secret History of the Urban Age: how its archaeological interpretations hearken back to their Ph.D work in literature, what lessons present cities might learn from ancient ones, and their “polyamorous” approach to working on multiple projects simultaneously.
