I watch ST: Eleven again a few weeks back, and this short statement keeps coming back to me. If Vulcan has colonies, traders, people visiting other worlds, ten thousand total seem a little low for the number of survivors, This has been pointed out before. But maybe Spock was referring to a different group with the ten thousand figure? Could Spock have been think specfically of the total number of Vulcan elders off of Vulcan at the time of the planet's destruction? Not just those aboard the Enterprise, but other elders spread throughout the Federation, and elsewhere. The ten thousand figure wasn't meant to be Vulcan survivors in general?
