You should use nested posting so you can recognize exactly what it is I'm referring to. I'm not talking about the film. I'm talking about your response to Ilkyu's posting in a more general sense:
Ilkyu said this:
with biodome-like recycling tech (just little more than basic aero/hydroponics) and chemosynthesis they would, at least in most scenarios short of complete planet obliteration. In this case scientists and engineers will always have a better shot
That is the "he" I'm referring to.
Part of what allows us the ability to not just persevere but proliferate is our ability to dream, invent, create. Every novel concept starts out as "unrealistic" until it isn't. A few hundred years ago it would have been "unrealistic" to think we could grow enough food to sustain a population of 6 billion. Genetic engineering has demonstrated otherwise.
But artificial biospheres aren't unrealistic, not at all. They've already been produced and experimented with. Perhaps it's not refined enough to survive now. But given the technological progress of civilization over the last 100 years, in 500 years why wouldn't there be? Why wouldn't better technology develop by that point to better predict the occurrence of upcoming natural disasters like supervolcanoes? Or satellite telescopes that can give us decades if not centuries of fair warning before the arrival of a catastrophic sized asteroid or meteor? That's not unrealistic at all.
Nor do I consider it "purely of luck" that 2000 people spread around the world were capable of surviving. That would be naive. There's always going to be luck involved in surviving a natural catastrophe of that magnitude. But there are reasons aside from luck as to why we survived while millions of others went extinct. Our adaptability as a species and our hominid ancestors before us were honed over millions of years.
