I known I, Creator 2 really blurs the boundary line. The whole topic of The Singularity is raising more questions as to at what point humans will play god because AI scientists and Physicists agree that now that we are making quantum computers (working computers the size of subatomic particles) at what point will we be making artificial consciousness vs artificial intelligence? Right now, quantum computers are just simple adding machines. What will they be in another generation?
Also, at least one Earth-like planet does exit in the star system closest to us, Alpha Centauri.
I thought this thread would be interesting to post here because science fictionn writers, artists, college teachers, and more have been duking out this very topic for 3 weeks now.
Josh is on the right track. And, I agree with him. Magic and the unexplained is Fantasy. And, technology and believable theories are what is science fiction.
I purposely wanted to blur the line like Star Wars, Dune, and The Fifth Element. The combination is not done very often.
Back on topic, what do others think defines the genre labels?
