A 1000 years sounds too much time to me. Quantum computers are already a COMERCIAL product, expensive, I agree, but on sale. I understand you are refering to the movie series "Terminator", well its kind of it, but not quite. In real life things are more surprising than in the screens. I don't know what religion you follow(if any), but I am sure you understand the concepts of God and the Devil.
Whatever they are, they are far superior. Period. They will always overcome us when the matter is intteligence. The antichrist is pictured as something that will just "appear" and will be the solution to all our problems, he would be "able to do wonders", but it does not talk specifically about it being a flesh and bone human.
