A digital discussion with Holly Jean Buck, Kim Stanley Robinson and Liam Young moderated by Amy Sherlock, Deputy Editor, frieze Magazine.

Architect Liam Young’s new film, Planet City, imagines a world in which 10 billion people live in a giant, sustainable city, leaving the rest of the earth to nature, free from human predation.

In conversation with award-winning sci-fi writer Kim Stanley Robinson and climate intervention researcher Holly Jean Buck, Young discusses his densely populated urban world and the technologies it uses and the already-existing technologies on which it is based.
