Kinda a pet peeve, but tape storage isn't dated yet. It's still king for large, long-term backups.Have you seen a Star Wars movie before this? They often look like that. The screen in the Death Star looked just like it did in A New Hope.
Tech in the Star Wars universe is not generically futuristic. They have space travel and hyper space but the Star Wars universe is pretty lowfi in many areas. They store their media on big physical tapes and floppy like disks. They do not have any sort of cellphone communication like technology. They do not have anything near as advanced as the internet (closest thing is the holonet but that is more like tv/radio).
