I do drive a car. It is irrelevant, insignificant and meaningless in relation to the real problems facing mankind. I can now travel farther than on a horse. There is still division, strife, suffering, etc. I could also argue the potential the car has for being, a detriment to society in ecological ramifications.
Same as "car"; am I to understand that you believe that the invention of the television has somehow caused a meaningful alleviation of strife, division, suffering, abuse, death, etc.?
You would need to demonstrate that any of the things you are mentioning actually have a meaningful effect on the problems the world faces due to, division, strife, suffering, abuse, etc. All you are demonstrating is the ability to state "things science has done" (I would also reject such things as "growing food for others" as something accomplished by "science" and rather by, farmers). I have not proposed "science has accomplished nothing" but that "investigation of the natural world (especially theorectical sciences) has produced no meaningful change, and no information with substantial or meaningful use in alleviating the problems of mankind."
Before medicine cured any disease, man was subject to crippling/deadly disease; after science cured X diseases, man is still as equally subject to crippling/deadly disease. Nothing meaningful has come of medicine in the face of the true statement "man is subject to crippling/deadly disease"
What has been cured is now irrelevant, as stated. Man has no worry/care about what he "can't get/doesn't have" but only about what he "can get/does have"; the fact that disease X is no longer viable does not solve the problem that dieases A-Z are still viable. No one with cancer cares that polio was cured. This is like playing a game of Russian Roulette with a gun holding 10,000 bullets, removing a bullet from the chamber and claiming you have done something "significant" when you have done nothing of meaningful significance. The man spinning the chamber is still going to be worried about bullets 1-9,999 and couldn't care less that one bullet is missing.
