its not over yet old hat
on a side note, with the author's use of terminology while describing the phenominon being so seemingly correct witin the given science, i wonder if ,when such a thing becomes a reality (big if there), these terms will be used by the scientists involved. kind of like the three robot laws of irobot fame. though on that note, the first robots will probably be developed for war, so the whole not harming a human thing falls off the shelf.
and the second robots developed for pleasure.
and, real quick, on the subject of robots, i think that self check out lanes, self regulted toll booths, and change givers should be made up to look like robots, huminoid like. then this would feel like the twenty first century, even if the machines themselves did no more then they do now, a huminoid head and voice would be appreciated. and more things should have space themed names, like moon pies and space pops. i'd rather be eating a galactic burger with saturn rings then the usual fare.
ok, thats way off the subect of the time ships, sorry
I finished reading it a couple of days ago.
They probably wouldn't use those terms but making swapping terms and then doing exposition to explain it to the reader is cumbersome.
Robots have been with us for a while now. They have been widely used in manufacturing for a while now. They just don't look like humanoid sci-fi robots. Their forms are specifically designed for the tasks they perform. Building a human like robot, especially one that walks like a human, is very difficult and inefficient. The first military robot is already here though it is rudimentary: the Tomahawk cruise missile.
