You people sound awfully sure about far-off future. How well, do you think, an educated Egyptian from, say, 2000 BC would have fared at predicting the future path of the society?
Was there any noticeable technological progress back in 2000 BC?
Looking at science fiction from the 19th century, aerial warfare, armoured land warfare, space exploration were all predicted. The details were all wrong, and I doubt we can predict the details of the future with any great accuracy. But the general theme of humanity expanding across the universe seems a safe extrapolation, even if I don't know whether the starships will be beam riders or ramscoops or wormhole navigators or Alcubierre drive or some other technology that has not yet been conceived.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
