EMORY: People said it was unsafe, that it caused brain cancer, psychosis, and even sleep disorders. And then there was all that metaphysical chatter about whether or not the person who arrived after the transport was the same person who left, and not some weird copy.
I would say that the implication here is that, whether we can understand the ideas or not, the transporter is not a kill-copy machine. And given the amount of use the device has seen, that's hardly surprising. Would so many people willingly go into a suicide booth with no more reassurance that a clone would appear at the other end?
