ok, so the question is actually “would you use a teleporter to save someone’s life not knowing if you would still be you afterwards”. i was thrown off by the train tracks because usually it implies sending someone else to certain death. thanks for clearing that up.
so i guess my answer would be of course. if transporters have become so ubiqitous that they are installed in seemingly random locations and with no fee or safety measures before using them i guess they are safe to use :)
well, as someone with a buddhist mindset that is not a problem for me :D
