I mean, a simple argument to be made is if creating a lightsaber is part of Jedi training (established in ROTJ), then it probably shouldn’t be an entirely technical process.
It’s a cool idea, but wouldn’t a more mystical reason make more sense in SW? E.g. the idea of bonding with a living crystal if you’re a Jedi, or “bleeding” it if you’re a Sith.
I don’t get why so many people don’t like the new lightsaber crystal lore. It’s such a Star Wars-y concept. They’ve even named them Kyber crystals.
because the inclination against the mystic side of Star Wars is strong among sci-fi nerds
the Emperor casually dismisses it as a ‘Jedi’s weapon’, implying that the Sith wouldn’t use lightsabers at all. Vader presumably only has one because he was formerly a Jedi.
And yet he does not have the same one he had when he was a Jedi. Worth noting as well that in an earlier draft of ROTJ the Emperor had a saber as well (and indeed Lucas gave the Sith their own sabers in the PT). I wouldn’t call the line dismissive, and I don’t believe it was written to be.
