We're not in anybody's smart lightcone. Observing
relativistic pioneer wavefronts by yet subexpansive observers
is arbitrarily improbable due to anthropic effect.

Even so, if you look out into the spacetime it's
obviously not very brilliant, at least at the
time the photons emerged there. This puts nucleation
density at low, very low.

Probabilistically also unlikely. Each trajectory
could well be unique. We have overshoot, but this
doesn't mean everybody should be as stupid.
