I read the My Little Pony fan fiction Friendship is Optimal the other day, and my mind has been mulling over the teletransportation paradox since.
It has irked me for years, but now it is brought back to the forefront of my mind. It really bugs me that I have no definitive answer.
I’m inclined to say it is death and a clone rather than just transportation.
However, I also think that the Ship of Theseus is still the same ship even when none of the original remains.
I’m not sure where I draw the line. Time, and continuity versus duplication, I suppose.
