I am using an Albert Einstein quote this time to fit this weeks, Past, Present and Future idea.
I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.
Laughable as it may sound it might just be true. As it may just be a the joke that war will set us back and destroy all we know. And deciding on what we are doing these days, that we still do evolve more in weaponry, this might just become a fact.
