Hawking appears mentally incompetent; he has to be removed from his current status.
Mostly, Hawking should fear steps, lakes and ice patches.
Stephen Hawking fears Trump could ‘push Earth over the brink’ and start chain reaction which wipes out humanity. ......................................... I’m no genius, but there was a time when there were millions on this planet using up our natural resources, now we are into the billions, just how long do you think we can exist with the population growing at a greater pace? The demands of humanity will increase along with the populations, we will eventually have eaten up most of our planet to make room for our expansion. People want stuff, and it takes resources to make stuff. GLOBAL WARMING IS PEOPLE! (LOL, I added some Charlton Heston there.) :^) The only thing that will stop population growth is an orgasm pill, or an Orgasmatron that we thought was a joke in the Woody Allen movie about 40 years ago. Do you really want to be around when the earths population reaches 1 Trillion? Sure, we may have found a way to get to Mars by then, and maybe start life on the moon, but we’ll be too busy trying to survive here on earth. I expect there will be more wars to end wars along the way, you can bet on it. Humanity is always on the brink of war, and no international organization will be able to stop it. Hawkings has his opinions like everyone else. I remember the Great Criswell, he made a living predicting the future, a couple of them actually came true.
