Cyborgs...WOW....I like the movies,but..........

I like watching sci-fi movies,but i dont know that i amprepared to live with cyborgs around me when all my life the movies tell me that in some point this machines are turning bad and kill a lot of people,and so happens that everything is getting back to normal just like is suppouse to happen in the film.
I just dont know how it will look like to live in a world like this..And a just a bit history from the net about the concept man-machine....:
The concept of a man-machine mixture was widespread in science fiction before World War II. In 1908 Jean de la Hire introduced Nyctalope (perhaps the first true superhero was also the first literary cyborg) in the novel L'Homme Qui Peut Vivre Dans L'eau (The Man Who Can Live in Water). Edmond Hamilton presented space explorers with a mixture of organic and machine parts in his novel The Comet Doom in 1928. He later featured the talking, living brain of an old scientist, Simon Wright, floating around in a transparent case, in all the adventures of his famous hero, Captain Future. In the short story "No Woman Born" in 1944, C. L. Moore wrote of Deirdre, a dancer, whose body was burned completely and whose brain was placed in a faceless but beautiful and supple mechanical body.
And as always the military gets the best and all the fun gadgets to play with....

The "cyborg soldier" often refers to a soldier whose weapon and survival systems are integrated into the self, creating a human-machine interface. A notable example is the Pilot's Associate, first developed in 1985, which would use Artificial Intelligence to assist a combat pilot. The push for further integration between pilot and aircraft would include the Pilot Associate's ability to "initiate actions of its own when it deems it necessary, including firing weapons and even taking over the aircraft from the pilot. (Gray, Cyborg Handbook)

Military organizations' research has recently focused on the utilization of cyborg animals for inter-species relationships for the purposes of a supposed a tactical advantage. DARPA has announced its interest in developing "cyborg insects" to transmit data from sensors implanted into the insect during the pupal stage. The insect's motion would be controlled from a MEMS, or Micro-Electro-Mechanical System, and would conceivably surveil an environment and detect explosives or gas.[8] Similarly, DARPA has developed a neural implant to remotely control the movement of sharks. The shark's unique senses would be exploited to provide data feedback in relation to enemy ship movement and underwater explosives[9].

Other proposals have integrated the mechanical into the intuitive abilities of the individual soldier. Researchers at the University of California, Berkeley have set out to "create an exoskeleton that combines a human control system with robotic muscle."[10] The device is distinctly Cyborgian in that it is self-powered, and requires no conscious manipulation by the pilot soldier. The exoskeleton responds to the pilot, through constant computer calculations, to distribute and lessen weight exerted on the pilot, allowing hypothetically for soldiers to haul large amounts of medical supplies and carry injured soldiers to safety
