Enjoy my daydreams

Have watched a movie “Summer Wars” on the TV program.  It is a Japanese cartoon movie and has described a person who finished a program to hack the computer virtual world, such as some computer games and some computer virtual applications.  The story is described the fire control systems, traffic systems, cell-phone systems… etc. had been hacked through the users’ accounts.  It was even able to change the satellite track to let it went toward to the appointed location.  Of course, the end of the story the hack had been fought off by a crow of people. 

We all know the computer games are virtual application software.  Nevertheless, do you know some of the systems in human real life are controlled by the virtual programs, too?  Such as, fire control systems, traffic systems, cell-phone systems, banking systems… etc.  When the hackers took the users’ accounts and security codes away, the hackers are able to change many things, like deranged alarms, disordered traffic lights, crazy time… etc., even the numbers of your money in the banking account will be changed.  You might not logo-in to your web accounts due to the passwords are wrong.  The numbers of your money will be changed to zero or the other numbers which is not yours due to the banking systems are hacked the programs.  How serious it is!!  Would you image that?!  What if the day was coming?!
