10 points!! What did Einstein mean when he said this?

Question

I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.

Answer 1

war should be less violent

Answer 2

Because our current weapons of mass destruction include friggin atom bombs that destroy everything and because we are literally on a friggin nuclear crisis/war c**p thing, by the time world war four comes around, we will have destroyed EVERYTHING . Thus, our only weapons will be sticks and stones. Einstein was a brilliant man.

Answer 3

He knew how dangerous the atomic bomb was and thought that it would destroy man kind. Rightfully so, there are some crazy people in this world and they will not stop trying to destroy this world until they succeed.  

Answer 4

after WW III there will be nothing left but sticks and stones.

Answer 5

He just meant that wwIII would be fought with WMD's and there would be no technology left to fight WWIV with anything but what's left.  That is sticks and stones.

Answer 6

on WW II they are using Einstein's atomic bomb, and that atomic bomb can destroy a whole city. He predicted that on WW III human will use a more dangerous weapon than his, and that weapon will destroy almost all of human beings.

So in WW IV they will use sticks and stones after the destruction from WW III

Answer 7

The fallout and ultimate result of nuclear war will be complete and utter destruction of everything humankind has ever developed and most likely the human race. Nuclear war will set the planet back to the Stone Age.
