Imagine we have Rick's ability, what kind of emotional concept will we have? If morty hangs, you can find another one. If the earth is destroyed, you can change to another parallel universe. The care and love that seemed to be unique before, now because of the portal gun, it seems that they are no longer the only existence. Will you still be lost?
Our protagonist will, so he's the one and only Rick.
Just like we always say that the ancient chariots and horses are far away, and a lifetime is only enough to love one person. Compared with the ancients, we live in a world with extremely expanded space and time (various technologies have changed the meaning of time to people), just like the world of Rick and Morty we see today.
