  We describe how the super Minkowski space-times relevant to string theory and
M-theory, complete with their Lorentz metrics and spin structures, emerge from
a much more elementary object: the superpoint. In the sense of higher
structures, this comes from treating the superpoint as an object in a flavor of
rational homotopy theory, and repeatedly constructing central extensions. We
will fit this story into the larger picture of the brane bouquet of
Fiorenza-Sati-Schreiber: string theories and membrane theories emerge from
super Minkowski space-times in precisely the same way as the super Minkowski
space-times themselves emerge from the superpoint. This note is adapted from a
talk I gave at the Durham symposium Higher Structures in M-Theory.
