Sounds like my initial conjecture regards C vs Si/Ge was exactly
backwards. The reason C might lend itself better as being the
substrate for life is in regards its higher reactivity at "moderate"
or low temperatures. It can function inside of hundreds of different
molecules. OTOH, lifeforms built upon Si or Ge might only be able to
exist at much higher temperatures, say deep inside the earth, around
volcanos, etc, where Si/Ge might persist in their more liquid rather
than crystalline form. Maybe that's the secret of carbon.

Yes. This what Asimov was talking about - possible chemistries under
different temperature conditions.
