[Star Wars] Why there is not more wireless technologies shown to be used?
gpt
Technology in the Star Wars universe is built to work. Not to look pretty, not to be convenient. Just to be reliable and to work. It has to work out in the cold of space and in the wilderness of a uncharted planet. It's highly advanced but also analog. 

You don't get that with wireless technology. It's too prone to failure, hacking, signal loss, etc. Droids interfacing directly with computers is old fashioned but reliable. So are discs and holographic projectors. 

That said there is wireless technology. Instant communication across the galaxy is wireless.
