“Next year: All carbon-based life forms.”
Is there such a thing as non-carbon-based life?
You are right, though, that’s the direction in which Time is headed (ell, that and towards bankruptcy). The following year will have to be everything that exists, I guess. Then everything theoretically possible. Then I don’t know.
There was once a Star Trek episode in which they encountered a silicon based life form. Kirk and Spock and the guys were surprised to find a life form which was not carbon based.
So at least in the realm of science fiction, there are non-carbon based life forms.
