I’m talking about a fan theory, that if true doesn’t drastically upend the fundamentals of the fiction it is set in.
Mine is that in the American Dad episode ‘Can I Be Frank With You’, that Snot’s uncle is actually just another Roger persona. He appears suddenly and conveniently to pitch a bizarre scheme, he loves hanging around with teen boys and doing drugs, and the very instant that the plan has a setback he kills himself out of sight of everyone else. That’s just Roger in a suit and glasses.
Edit: Ok, so, people are having trouble with the word “inconsequential”.
Terminator, the Matrix and Dune are all the same universe at different points in time.
I don’t buy this one for the single reason that time travel is never a thing in the Dune universe and their tech is astronomically better than the other two.
Not necessarily, people don’t travel through time in Dune but they do see through time, and Spice specifically enables humans to see the past and future. I can theorize that actually traveling into the past is something only intelligent machines were able to facilitate. It could also be a situation where the high tech solution (lasers) has already been countered (shields) so the low tech solution (swords) becomes the better weapon. It could also be by a mutual agreement, or simply lost tech.
