man just can't help fiddling round with even the most basic technologies in order to make them better. as soon as something new is created, people, particularly scientists, inventors make efforts to make the life of humankind much more comfortable. automats, robots and complex machines were and still are created just to automatize technical processes, devices are constructed for domestic needs. there is some joke, or so-called people belief, that signs all the inventions that have already carried out by present and take place just because of man's laziness. i mean, they happen on earth because people want to make as less moves by hands and feet as possible. for example, men didn't want to jump and run every time to change tv channel, so they invented a remote-control station.
