Soon enough, things will be controlled by machines, leading everything to being efficient where there’s no ‘play’. Especially, artificial intelligence will make the majority of simple jobs easier, so human beings won’t need to do them at all. It will be easier to live and you will have more time. Even without doing anything, you may be able to spend your life without problems if it is a passive life like robot’s. It is an era when you do not need to be desperate to live. It is said that enterprises pursuing happiness, joy, peace and services offering them will increase.
