The original post, if I remember correctly, dealt with the possibility
of seeding the atmosphere of Venus with Thermo-acidophiles and
then seeing what they evolved into. In this context the constraints
on what conditions terrestrial life forms can grow under are
relevant, whereas any considerations as to what non-terrestrial
life forms COULD consist of are beside the point. However if you
didn't see the original posts, you could hardly have known this.
