You do not accept the possibility of hypothetical ETi tech being more advanced than our own?
Absurd.
How do you rule it out, Jay?
I think that's all "my" authors are saying; the possibility should not be dismissed so easily.
Is the idea any less plausible than the current SETI assumptions, that ETi is only so advanced to be out there in their "goldilocks zone" leaking radio, sitcoms and beer commercials?
