“My body looks like a computer.
But that does not mean I am not alive.”
– Greta

A riveting and thought-provoking new play about artificial intelligence and the future of family

The New York Times

Synopsis

Sisters

Matilda and Greta have always been there for one another, through joy and grief and homework and boyfriends. They’re as close as sisters can be—even if Greta is artificial intelligence. As Matilda ages and Greta longs for independence, their relationship begins to be tested like never before.

Told over the course of 90 years, Sisters is a riveting and thought-provoking new play about the future of family.
