I don't mean that if a defintion of "computer" applied to everything
the *computer* would be useless.

I mean that if a defintion of "computer" applied to everything
the *definition* would be useless.

Are you prepared to argue that the aforementioned Klingon AI suddenly stops being conscious when the last copy of the manual which would allow us to interact with it is destroyed?

Hmm. Including limitations in time?
