  Everlasting inflation has far-reaching implications for cosmology and the
standing of self-localizing inferences made by observers, which have been
subjects of renewed interest in light of the growing acceptance of theory
landscapes and the attendant anthropic arguments. Under what assumptions and to
what extent does inflation generically produce an eternal "multiverse," without
fine-tuning with respect to measures over the space of inflationary cosmologies
driven by a single minimally coupled scalar field? We address this and related
questions with numerical simulations of inflationary dynamics across
populations of randomly generated inflation models, instantiating a few
particular simply-defined measures.
