I suspect there is a tipping point. If there is sufficient automation and information available, a very small number of people could potentially reproduce/rebuild a full high-tech society in a short amount of time. Vinge's "Marooned in Realtime" engages in similar speculation. IIRC his requirement for preventing inbreeding was something on the order of 20 people -- much lower than the parent article's 150 bare minimum, with 10K being more realistic.
