You know what's weird? The fact that no one in the star wars universe invented a smartphone. Like, they have sentient robots, spaceships, and holograms, but no one is using anything that resembles a smartphone. Sure, they can send holographic messages to each other, letting people know there is a clone army on Kamino, or that they are each other's only hope, but you never see anyone doom-scrolling through Geonosis's version of Facebook, or posting memes about the empire. No one is sharing pictures of their Kowakian monkey-lizard or videos from that one Bantha trip they took on Utapau.
And wouldn't you assume C3PO and R2D2 wouldn't get lost on Tatooine if they had a built-in GPS system? And why wouldn't they? Sure, C3PO is just a protocol droid but R2?! He's like a Swiss army knife on wheels! Do you want to tell me he has two jetpacks built into his legs but no GPS system?!
