Will Wise, of the Project Blue Book Archive, has responded to "Borg... or Highlander". You can check it out at his personal blog, Rational Geek.
Will is one of the bright, young(ish) guys engaged in the serious study of the UFO phenomenon, and is well worth a read when he has something to say about the subject. I'm hoping we get the opportunity to interview him for Best Evidence: Top 10 UFO Cases (a question of time and available travel money).
And, for the record, Natalie Portman is a fine choice for a cyborg body!
