  Recent no-go theorems on interpretations of quantum theory featuring an
assumption of `Absoluteness of Observed Events' (AOE) are shown to have an
unexpectedly strong corollary: one cannot reject AOE and at the same time
assume that the `observed events' in question can all be embedded within a
single background space-time common to all observers. Consequently, all
interpretations that reject AOE must follow QBism in rejecting a `block
universe' view of space-time.
