i suspect that those who found the new bottles wouldn't be too concerned
with hanging around to save all their buddies, it would be far more
efficient for just maybe 4 or 8 of them to take off and colonise each.
there's not enough room in spaceships these days, you know, let alone
enough resources to make enough of them to shift 3/4 of a jar full of
bacteria. each new bottle would eventually reach its carrying capacity
some time many generations off in the future, in which time of course a
few with access to the resources would probably once more make it off,
but not with enough time, or ability, to save everyone...

somewhere along the way they're bound to discover cold fission too, and
that'll make everyone happy and fulfilled, like on the telly.

ok,
