First, what is Dynamicland really about? I would contrast it with virtual reality, augmented reality, the "metaverse", etc., the point of all of which seems to be to bring the world into a computer. (See also: "brain in a vat", "we live in a simulation", etc., which take this idea to an extreme.)

The key idea of Dynamicland, it seems to me, is instead to bring the computer into the world: to enable computation with real-world objects in a setting where all "code", "input", and "output" is instantiated in a physical setting 3/
