Star Trek Tech That Exists Today
Esther Schindler writes "When Star Trek hit the air waves, talking computers were just a pipe dream. While teleportation remains elusive, several once-fictional technologies are changing the way people live and work. Here are some ways in which we're approaching the gizmos that Star Trek demonstrated. Speech recognition? Check. Holodeck? Sort of. Replicator? Workin' on it."
This article made me think of all the technology that came before Star Trek. I'm not an old timer, but you had sliding doors and turbolifts (A.K.A. elevators) back before the sixties didn't you?
If by "pipe dream" you mean computers were synthesizing speech five years before Star Trek came out, then sure.
