If you could have one piece of science fiction technology?
What would you choose?
For me it would have to be a teleport/transporter. Especially, something like the personal teleport seen in Dr Who, The Tomorrow People or Star Trek Discovery.
I would like to visit distant lands but get badly travel sick.
Teleport and transport would be amazing, but I'd be worried about ending up in some random location in outer space or like halfway through a boulder, or my duplicate would end up stranded on a deserted space station.
I'm going to pick the replicator. Food, parts, medicine, clothes, as long as the structure is on file, I can 3d print anything I need. And if I'm the only who has one, it's basically infinite money as well. If everyone gets one, well at least we'll solve world hunger. That's better than being rich, I guess.
