Compared to the age of the universe and our galaxy, the timespan of our civilization is ridiculously small. Provided our civilization does not destroy itself, we have little clue to how the future will look in one thousand years from.now and absolutely not the vaguest concept of the capabilities of a civilization which is a million years older than ours. Once we are ready to travel interstellar distances I suspect our technology will look totally different from.anything we have now.
