I agree with both Hawking and you. What I think of as the American style of having rights, freedoms, and capitalism can be great for individuals but not necessarily good for society or even humanity on the whole. The trick is to find a balance between the two. By avoiding disasters do we mean famine, inhospitable climate shifts, war, what? Excluding world ending events, dealing with adversity has been a part of human history for centuries. Plagues, bacteria before antibiotics, hurricanes, you name it. I think that this is all simply a quality of life issue. The quality of life may sharply decrease in the future, but there will still be life, and hopefully humans.
