Would you use teleporter technology if it existed? Why or Why not?
You know those sci-fi teleporters like in Star Trek where you disappear from one location then instantaneously reappear in another location? Do you trust that they are safe to use?
There's a Ship of Theseus aspect to Star Trek's transporters in particular that I find interesting. In that there is an actual matter stream sent to your destination. But ultimately I couldn't be sure that the me I am now would come out the other side - and I probably wouldn't.
I have the same concern about uploading my brain to a computer. Even if it's a perfect copy it's still a copy. And that's before you factor in for other things like, I am not just my brain I am also the hormones that affect my brain.
Your hormones make you weak! Let go of your mortal shell and live in the sweet embrace of 1s and 0s. None of those pesky shades of gray. Everything in it's own happy 'float'ing bucket.
We'll even throw in a RNG if you ever want to get the thrill of hormones.
Thousands of usenet, IRC, BBS, forum, and reddit posts have gone back and forth on that since that episode first aired. Canon is that the transporter disassembles and reassembles and that the transport consists of, among other things, a matter stream. But also the technobabble in the episode suggests that the transporter recreated at least one of them without an extra riker worth of matter.
Replicators also require base materials to synthesize meals out of.
