Except that this time the disaster has probably little to do with nature. I'd add that, given current situation, 10,000 years seems a bit of a stretch. IMHO it's more like 100 years to the first "maybe" - or more probably even a fraction of that.

Sure, but the point is, the planet will be fine in 10k or 100k or 1M years, it'll still be orbiting the Sun. We probably won't be here any more because we'll have killed ourselves off, but that's OK, some other lifeforms can take over. Hopefully they'll be more successful.
