In contemporary society,artificial intelligence devices which are monitered by smart computer softwares are playing essential role in people 's daily lives.Thus,some people may predict the computer system in future will be so advanced to replace the function of our brain.In my point of view,our brains are indispensible and can not be replaced.
At the begining,now matter how sophisticated the computer softwares are,they are all created by our brain.In other words our brains are prior to all sorts of devices.Besides,it is human that perceive the drawbacks of computer system and try to update them constantly.Therefore,our brains are much more sophisticated than all electronic devices.
Moreover,there are a great number of things tha cannot be done solely by computer.For instance,although the high-intelligent communication devices are full of our lives such as cell phone and internet,human is still the main body of the communication.Those facilities,which can help us conquer the problems caused by distance,can not think for us.
All in all,even though the computer system nowadays are highly developped the funcations of our brains are still indispensible in that they create those developped techniques and ther e are still many things can be done solely by computer.
