B # 2 Machine what is really going to happen in the future?

I found this on you tube the other day this video,to some degree proves my point mankind is coming into the age where now machine are going to do the majority of work for humans. Now if machines could think and develop free will who to say that machines won't try and take over. If mankind can create somethin to ligthen the burden for humans the next step is to make the machine think. I am not saying that it's a bad thing ,but you must remeber we as a race are not perfect and still have a few, to say the least, bad seeds. Now I am not saying we as a people do not need machines I am saying we must think before we act. all the sci-fi movies about machines taken over in my personal opinion are more ture than we think.
