Being super useful has a few requirements. Elephants, for instance, are incredibly useful. They’re large, they carry burdens well, they can be trained and will behave well if they’re treated well, they’re social and understand commands.
But they have one baby every 22 months and it takes years before they’re fertile. So they’re not super useful. Rhinos, similarly, do not reproduce fast enough to check off the super box.
