Star Wars is a nice movie but it’s a pretty mediocre SF. They mix very low and very high technology in mostly absurd ways. You have FTL and lasers but robots are mostly shit, AI is very basic and its use weirdly limited, warfare looks pretty much like today, only in space. I know they did it like this because of cinematography but as a SF it’s just not that good. So I really wouldn’t bother trying to rationalize the tech. It’s mostly like this because “it looked nice”.
I meant “today” in SF sense, like current century vs some time 1000 years from now :) Of course your right, the battle scenes were inspired by WW2 movies.
My favorite SF warfare descriptions come from Banks. Battleships firing at each other from light years away or hiding inside suns, everything controlled by AI, microsecond long battles. Absolutely not adaptable to screen.
