The document is a declaration of intent and introduction to a paper by Luciana Jaalouk on designing immersive experiences. It begins by stating the importance of understanding ourselves before designing experiences. It then discusses the concept of a "Playground" which serves as a school for humans, aliens, and bots to learn through play. The key aspects of any playground are described as existence by default, participation by default, and safety by default. The document emphasizes that play allows one to navigate nonsense in life and that any designed experience must prioritize these aspects of presence, participation, and safety.
