Sarah Connor is safe- for the time being. Robotics engineers pitted robotic arms equipped with polymer based artificial muscles against a 17 year old girl, who describes herself as a wimp, in an arm wrestling contest. The wimp won against three different robot arms.
The bad news for Sarah Connor, however, is that the originator of the contest didn't believe it would be possible for it to actually take place for decades to come- when he suggested it in 1999! While we still don't have ray guns and flying cars, there are huge advances being made in some fields.
Here comes the future.
