In the history of mankind, I've only heard stories of a couple of people who didn't die. In fact, most people die horrible deaths. That fact won't change, no matter how far mankind travels - or doesn't travel. If we manage to cure cancer, and all mankind's other ills, that will be great. But, I don't believe that we ever will. Even if we cured the five most lethal diseases that we know of today, there will be something new to worry about tomorrow. We have been waging biological warfare against nature since the earliest ancestor crawled out of that primordial soup, and nature will continue that war until the last man and woman have died.
There is no utopian solution to poverty, hunger, and disease. I simply don't believe in such a solution. The past hundred years or so have been remarkable victories for mankind, but there is simply no reason to suspect that we will see no setbacks. Polio has been defeated, mumps, measles, and others have been set back seriously, but we are breeding new superkiller bugs in our hospitals and medical centers right now. Oh - the flu. It mutates and changes rapidly - we could experience another 1918 at any time. What was the number? 21 million dead, around the world, I believe? With our population levels today, the next time around could see those numbers increased by a couple orders of magnitude.
Life is precarious. If you are a Russian, I would suspect that you are more aware of that fact than I should be.
