Future tech is impossible to predict or say one way or the other with any reasonable certainty for most things. We can notice things that seem absurd, like how the amazing technology of seat belts seems forgotten in ships which toss everyone out of their seats every 15 minutes But as far as faster than light travel, cloaking, etc :
In 1911, if you told the leading physicists on EARTH that you had a device small enough to fit in a pocket that could take photographs, high definition video, and hold tens of thousands of books, or that you could store literally millions of books on something the size of a child's shoe, would they have said you were utterly insane? Also consider that the leap in tech from 1811 to 1911 was pretty pathetic compared to 1911 to 2011. Who can really say what will be possible in 2111 or 2211, assuming we don't divide ourselves by zero in the meantime
