OK, looking ahead 1000 years is not easy. I doubt anyone living in 1014 had any inkling about some things we have or do today. Oh, sure, some folks could have made up some kind of fantastic 'fairy-tale' that might amuse children or anyone else gullible enough to believe any of it; and perhaps some even could have speculated pretty accurately about some things, but not most.
In 1000 years (if Earth still exists), I believe tremendous growth in intelligence and wisdom will flourish, and I believe humanity will evolve and grow toward much less conflict and war, and much more acceptance, sharing, and love. Of course, MUCH MORE will change!
