Star Wars universe does have lasers of all scales and power levels.
Yet literally no one uses them well on a personal scale.
The Jedi (and Sith for that matter) imbue it with a power of magical stone, and then…use it as a saber.
To balance this stupidity, stormtroopers, clones and droids all use slow, non-continuous energy blasters. With actual lasers, they could insta-kill any Jedi, but they cannot, because otherwise the movie wouldn’t exist.
Yep!
The sort of proto sabers seem to be prior to them figuring kyber crystal magic, iirc, and needing to carry a more crude power/plasma source with them.
Sort of like a radioman in WW2 had to carry around a whole backpack sized radio, whereas nowadays we have like, a cell/smart phone, or just a proper encrypted handheld radio with way, way superior battery/power system in a more compact package.
