It lets you view modern life from outside.

Which of the things we do every day are truly necessary? When you remove something or add another, what happens to the greater shape of society? What do our relationships to each other look like without cars, without jobs, without money? What might take their place?

What does it mean to be sentient? What does it mean to be human? What’s the shape of the gap between those two things?

I find it philosophically entertaining.
