The head of New York City's Department of Transportation sees his task as building an egalitarian city. "Transportation is a human right, but in the past most of the investment in transportation didn't go to the working class." Cars, bikes, and social justice.

A conversation with the basic, free, web version, using its default voice. Like my human guests, it chose the three topics, and I did just the usual light editing. Good news: it says, "I'm on your side, not on any destructive path." Bad news: this is what the space aliens say in every sci-fi movie just before they try to destroy the earth.

We tweaked our format to Tree Tree Tree for this arboreal photographer, who specializes in the immense and the ancient—2,000 years old, 3,000 years old—many of which he's archived at the Gathering Growth Foundation. The big and the beautiful.

Brown, the founder of Evidence, a dance company, says, "You'll see yourself on stage." I hope he's speaking figuratively. Cabuag, its associate artistic director agrees. Presumably.

This set and costume designer worked on 80 Broadway shows, 30 films, several operas, and innumerable dance works. Here's a tip he gleaned collaborating with Paul Taylor: "Give a man 17 chairs and see what he comes up with." Good advice for any part of life. Presented with the Paul Taylor Dance Company.

For decades after graduating, these architects avoided Cooper Union. "We would detour three or four blocks or else the PTSD would kick in." Apparently it used to be like The Paper Chase or Whiplash but with less compassion. Presented with The National Academy of Design. Music: Karl Schwarz.

This preservationist, a wily veteran of decades of urban campaigns, is happy in his work: "I've never regretted being involved in saving a landmark. I've only regretted the ones I couldn't save." I envy his serenity. I regret nearly everything. Presented with the New York Preservation Archive Project. Music: Adrian Untermyer.

When this playwright's grandfather faced a tough decision, "He sought the advice of Paul Robeson." Of course he did. Who wouldn't? And it all worked out fine. Fine-ish. A writer, his family, his community. Presented with the Classical Theatre of Harlem. Music: Emery Mason, Melissa Mosley.
