Sigh-Fi

Yea I agree.

I can't remember if the Brian Herbert books or just my own trying to resolve that in my own head but I feel like I ran across an attempt at resolving that saying that even world sized computer systems of the thinking machines still had worse results than the guild navigators since the navigators weren't actually computing routes so much as using dune's bizarre mental abilities like telepathy etc. to directly reach out and connect to the destination.

Actually that could even be from one of the movies and TV. Blurry memory on it.

Love Dune overall and very glad it is in the world of well known stories now with things like the warnings against charismatic leaders etc. but it still definitely has its flaws.
