 Taken literally, Robb-Stein-Dieks point presents cannot be shared, which some find an unattractive feature of that view. Causal diamonds, on the other hand, are surprisingly large. For a specious present of length three seconds, the corresponding causal diamond includes the moon (that is, a contemporaneous bit of the moon’s history). As the length of a specious present shrinks to zero as a limit, the corresponding causal diamond shrinks to a point, regaining the Robb-Stein-Dieks view as a limiting case.
