In Mary Roach's book "Packing for Mars: The Curious Science of Life in the Void," the author reflects on how modern life has shifted towards more simulated experiences, causing people to step away from physical play and outdoor activities. Roach emphasizes that technology has woven itself into daily life, often replacing real interactions with virtual ones, leading to a culture where playfulness is diminishing.

The quote, "No one goes out to play anymore," encapsulates this concern about societal changes. Roach suggests that as these simulations become more immersive, the distinction between reality and virtual experiences blurs, impacting how individuals engage with the world around them. The essence of play, which fosters creativity and connection, risks being lost in the process.
