Well, it's usually easier to show than tell, but my father who was King of Altea built the Lions of Voltron, large robotic spaceships that connect with their pilots' minds and personalities. We used the Lions to bring peace to many nations and species in my world. Most of my castle -- which was once a spaceship as well, but is sedentary in this world -- utilizes technology that requires an Altean mind. We also use holograms. A great deal of technology here requires manually pressing buttons.
