Humans vs. machines, both have systems and both perform functions and tasks, but there are many differences that separate humans from machines. First machines are created by humans and therefore their level of knowledge have been programmed into their computers by humans. Machines do not have feelings where humans do. Humans can feel pain and emotions, where a machine has no feeling of pain or emotions. Humans are made up of organic material and are living systems, where machines are made up on non-organic material and systems that are programmed.
Many have speculated that machines could one day take over the world. I guess it is possible given the advancement in artificial intelligence and machine learning. Machines could begin to learn on their own and then could possibly surpass the intelligence of humans. This would probably be in the far future if ever. Until then I think leveraging machines to help humans accomplish tasks and functions quicker is a good thing. One thing that humans and machines do have in common is that we are ultimately made up of stardust and therefore come from matter that makes up the universe.
