We don't use smartphones from ten years ago (or phones from ten years ago, for that matter), but practice beliefs from 500 years ago. Humans are organic machines; that function perfectly, when we learn how to take care of ourselves and each other - it's #time for a system upgrade people - right?
If each person respects himself and others, loves his family and friends. Live by the principle: treat others just as you want them to treat you. If we think before we talk. If we try to love all life. If we get rid of the debris in our head. We will be happy and calm. Religions teach the same thing. If people do not distort this world, then we do not need a reboot.
