Not everything lasts forever. Like it says in a Star Wars book, even stars die. Star Wars is 50 years old next May.
Franchises like it or not do have a life cycle. Some go into the dustbin of history and become culturally irrelevant, like Buck Rogers and Flash Gordon.
I just never thought it would be Star Wars. It’s not quite there yet. But Disney has wrung the well dry, fairly quickly in a decade.
As older fans age out, they need to recreate and reenvision Star Wars. But at what point is it Star Wars in name only.
Star Wars is different things to different people. for some its George’s personal story and Saga, for others it’s the expanded material.
And like people have a different opinion of things, does it have to have lightsabers, Jedi, the Force to be Star Wars? Does it have to be about the Skywalker family and be a numbered episode with a roll up or crawl as it’s called.
