It's interesting how quickly the grey-gooers can write off natural life,
as if we would be able to invent stuff which could get out of control
and kill it all off overnight. Biological life is pretty hardy - how
long would it be before bacteria or insects or something developed which
could feed on the alleged goo? After all, it would probably be made out
of similar stuff to natural life, given that it lives in the same
environment and has the same resources available.
How quickly would natural life develop, which could outcompete the
hard-life, and to whose presence the hard-life could not adapt? This is
especially likely if the hard life was some heavily tuned soft-life
eater, because it would have to be so specific that it would have
trouble adapting to new environments.
