This question already has an answer here:
A question I've always had when watching the Star Wars franchise is: Why use laser guns? I understand it's a different galaxy and technology may have advanced differently than on earth, but surely at some point they could have developed something similar to traditional guns.
Especially against the Jedi, where lasers move slow enough such that they can be stopped real time by a beam of light. Or against anyone really with decent reaction time and good eyesight.
It just seems to me that the super slow speed of lasers is constantly getting people killed and is just impractical. Snipers would be almost useless in Star Wars.
Also it's not like their laser guns are massively more powerful than a bullet; we see them hit walls and unarmored people and it doesn't seem to do more damage than a typical rifle round.
So why are they using such an ineffective weapon? Or why can't they at least make the lasers move faster?
