So, basically, you think we should NOT work towards the goals of improving the human condition then?
I think the premise is faulty, and proved as such with one example: Science has eliminated Polio and Small pox. And, given enough time and energy, why could the other items not be eliminated?
Jobs for everyone would be easy: Science opens new areas of employment, and new resources to exploit. Science and technology can eventually end hunger, given enough time and energy devoted to things like increasing crop yields.
