The Dune timeline in the books covers something like 20,000 from the beginning of interstellar space travel up to and through the Atreides dynasty and all it kicks off.
I believe Frank Herbert took the stance that once technology gets to that level, it remains static as there is little else to discover/develop.
I believe that Herbert intended it at some level, I just don't think it was well-considered as world building.
It is fine though, as a way to handwave anything that doesn't make sense and to underline just how weird this setting and these people's cultures are going to be. This is not to denigrate it. It's just more a storyteller's trope intended to tell the audience to settle in and leave your expectations behind. I guess this show will step in just after the end of the Butlerian Jihad maybe, but the ebbs and flows of human cultural change over 10,000 years means that it's just one more thing he was intentionally not focusing on, and making a very specific prequel about an era that should be almost lost to the mists of time is inviting questions the "Duneiverse's" nerd-infrastructure is poorly equipped to handle.
I'm sort of just musing, though. I'll absolutely watch it, and if they tell a compelling story I will smile and shrug and not let it affect my enjoyment.
I like the Butlerian Jihad and resulting ban on even the simplest of “thinking machines” as a way to help explain away any anachronisms, too. Clever solution.
I also appreciated that the recent movies haven’t tried to explain that, but hinted at it with, for example, analog gauges in the ornithopter.
Considering the title I’m guessing this will cover the inception of the Kwisatz Haderach program by the Bene Gesserite. A long term human genome program thousands of years in the making and undermined by the premature birth of Paul when his mother was supposed to have a girl instead.
I absolutely believe it's been set down. It's just a weird number to have picked in the first place, a full 20k years or whatever into the future. It feels more like Frank Herbert originally just wanted to say "all that happened a long god-damned time ago... don't fixate on it." Yet here we are, fixating on it. If it's a good show, I won't mind at all, but I find it amusing.
Maybe but it also shows has humanity has gotten complacent/stagnated which is a key plot point in the later books.
For that you need time for various events such as the guild, the butlerian jihad, etc and then time for everything to be in a kind of equilibrium for millennia
