  Causal set theory offers a simple and elegant picture of discrete physics.
But the vast majority of causal sets look nothing at all like continuum
spacetimes, and must be excluded in some way to obtain a realistic theory. I
describe recent results showing that almost all non-manifoldlike causal sets
are, in fact, very strongly suppressed in the gravitational path integral. This
does not quite demonstrate the emergence of a continuum -- we do not yet
understand the remaining unsuppressed causal sets well enough -- but it is a
significant step in that direction.
