The Switch Zelda Games contain a Bootstrap Paradox:
The Sheikah Slate was created based on notes discovered in ancient ruins by the Ancient Sheikah. The Purah Pad was created after the Sheikah tech all stopped working/disappeared. The Pad goes back in time with Zelda, gets studied, documented, and eventually, the notes are found by the Sheikah.
