A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Is that canon? It seems that digitalization is not a thing in Pokémon.
In Legends Arceus they explain how Pokémon can naturally become smaller and Poke Balls are just empty containers which trigger that reaction. Kinda makes sense given that Poke Balls apparently were invented before anything digital.
Idk if any game ever explains how they are then stored in the PC, but according to PokeSpe, Poke Balls are physically sent and stored in literal boxes.
Literally in the first Pokemon game on the good old Gameboy there is the system where the Pokemon are send to and stored on "someone's pc". There is no post box system but just a PC where you can send (and retrieve) your Pokemon from anywhere on the continent in a split second, a speed not possible with the postal system.
