Exactly! But it's at least more fun proclaiming our undying alliance
towards the Elders of Zion, and plotting nefarious schemes towards dusting
white supremacists from air with outlook-modifying nanoware by swarms of
pretty attack butterflies (or, for extra demoralization, by armies of
buxom valkyrienes, led by Loki).

The universe is less cerebrally oriented. All she has on his mind is sex.

How should we stop doing that, rather? The scenarios how one could end all
diversity, and arrest natural expansion are not many, and not very
convincing.

(Moreover, sex is more fun).

Waste of effort to you, but not to your children. And their children. And
their children's children. And their chi... erm.

They are free to take whoever picks them up first. Children are not free,
but are not that expensive, either. Plus, you're wired to like making
them.

You'll notice that despite all the costs and risks people still continue
having children. Sure, you can contemplate rewriting the minds of billions
of sentient entities (most of them highly suspicious, and intrinsically
loth with anyone tinkering with their agendas), but this clearly a low
probability event, barring semidivine interventions (go away, Eliezer).

All it takes is a single expansive nucleus to walk all over the place,
whether it's pristine stellar excreta, or less-than-power instances of
life. Interstellar jumps are a piece of cakes, intergalactic ones are only
marginally more complicated (basically requiring a different seed design
and propulsion strategy).
