The thing that gets me is they have holographic displays but they can't figure out that it's a bad idea putting the pilot of a military ship right at the front with their head sticking out.
But in cinematic terms the R2D2/C3PO double-act does make for some funny exchanges, so I guess that's what they were going for. So its kindof tropes first, world-building afterwards as an afterthought.
The organic ones aren't treated that well either.
