"Hawking warns...Humanity must come together if we are to overcome these challenges..."
So, in other words, you must cure humanity of the pure unadulterated, narcissistic greed that has created the chasm between the elitists and the rest of the human race.
Fat fucking chance of that shit happening.
Defeatism will definitely prevent anything from happening!
That said: good people working hard can limit greed and its ill effects, though obviously not eliminate it.
Greed in particular is a fucking "mortal sin". How the hell did we go from "mortal sin" to cheerleading it? WTF?
