  At the moment we can’t find any life at all in the known parts of our universe, so I’d say it’s unlikely that anything will come and make us slaves anytime soon! Unless they have very impressive teleportation skils (and we know this is very difficult!!) or live for very long times, I’m not sure how they’d get here either!

  Probably the most likely is computers. Lots of people already seem to be taken over by their smart phones!
