Something I've always thought about the transporters, other than them killing the original you, everytime you use them. Is why when someone gets a disease that they have no cure for, why they just can't call up an earlier, pre diseased version and pop out a new you. I know someone jumped on me for saying that they kill you each time, but they absolutely do. I even found a video of a guy who explains it in more detail, than I've ever been willing to do. Its like arguing about who would win a fight, Batman or Superman, lol.
Of course, the transporter is specifically said to convert a subject to energy, transmit it to another location, and reassemble it into its original form. So, no, it’s not a suicide booth. O but the very existence of this technology would change the Federation and human life as we know it, and the reality is that it’s a plot device to get characters from place to place. Episodes which deal with certain logical questions (like Pulaski reintegrating as her younger self in “Unnatural Selection”, Thomas Riker in “Second Chances”, etc.), begin raising all sorts of questions. The potential to create endless clones, possible immortality, etc.
As it happens, John Byrne’s IDW TREK comics had a very interesting a story about an alien society using transporters to live forever.
Meanwhile, the
second most famous teleporter in pop culture—from THE FLY films—also carefully avoided such questions, because, again, it was a plot device. In the 1958 original, Andre Delambre’s disintegration-integrator worked much in the same way as TREK’s transporter, by transmitting atoms from one booth to another.
David Cronenberg’s (Happy 80th Birthday! I forgive you for slumming on STD!) 1986 rethinking of THE FLY went with the more realistic approach (as far modern scientific theory goes): Seth Brundle’s Telepods recorded the pattern of a subject, disintegrated it, then perfectly reproduced it in the receiving pod. In other words,
data was transmitted, but the original atoms were not.
Of course, the Telepods being suicide booths raise all sorts of nagging implications and questions, so the film only hints at how they actually work, so as not to distract from the actual human story of terminal illness that’s being told. It would distort the narrative and the emotional thrust of the film if they’d come right out and said that Brundle killed himself and was replaced by a perfect duplicate (but which now had fly genes interwoven with his own).
