Human minds are always being superior to machines,but it is too conceited for us individuals to belittle what machines can achieve.Many existences must attribute their emergence to human minds,such as computers and cellphones,yet some do cause consequences more devastating than human can ever imagine,one case in point:the 1986 Chernobyl disaster.Chernobyl nuclear power plant was designed and controlled by the Russians innocently until it ruined thousands of miles of rich land and dozens of generations of ordinary people because of its nuclear leakage.　　　Human mind and machine share similarity and each holds its own selfdom.As mentioning of functional diversity,humanity is surely far more developed.Both humans and machines can count and calculate but human brains have neurons dealing with emotions while machines do not show any expression of happiness or sadness.Machines can't think initiatively,or do anything spontaneously.There is no sign that any substance will fix this weakness.Since the 19th century,trains have been designed more and more intelligent,but not a single signal has shown any clue that it will turn into an "Irongut Train Man" -the hero,who was a human-like creature,of a series of cartoon named "Irongut Train Man",yet.　　　People made machines for releasing labor force from hard physical working.All existing machines are tools of human beings. For example,automobile is a kind of vehicle of transport produced by human,in which people feel easier than walking when traveling a long distance.Moreover,machines can compensate shortages of humans,which refers to such capabilities as strength and calculation.Albeit a variety of machines are stronger and faster than us individuals,they are made to be such a beast rather than ought to be.Airplanes,for instance,are huge in size and heavy in weight because people made them to be,because human want them to carry more individuals at one time and stay safe during the flight.　　　However,machines might threat humans on aspects vary from nuclear explosion to traffic injuries to body damage and to mental intimidation. The serious radiation leaked from damaged Fukushima-Daiichi nuclear power station,Japan,destroyed cities and valleys,hurt the nation and neighbors.Lots of volunteers were radiated to death,whose kinship suffered bereavement subsequently.　　　We admit that human minds do get beaten by machines sometimes,like Deep Blue,a chess-playing computer developed by IBM whom won the chess match against world champion Garry Kasparov on May 11,1997.Furthermore,people are making machines smarter and smarter through innumerous programs such as the Blue Brain Project,an attempt to create a synthetic brain by reverse-engineering the mammalian brain down to the molecular level,which announced that the super computer had successfully stimulated certain performances of mammals.Yet human intelligence is depicted as the dominant one in most occasions since all machines' procedures are preset by human.However,machines can be dangerous if we individuals don't use them well,exemplified analogously with that human is superior to  rattlesnake in the food chain and webs,but its venom is always a treat.  　　　Indeed,historical evidences show that human minds is superior to machines,however underestimating the force of machines might irritate menace that beyond human's management.
