I do not know
what technocentrism is really and have an slight understanding of nanotecnology but the fact is everything capitalism is built on is based on the use of poor labor, women and children working 12 hour days for pennies... The US currently uses 60+ percent of the worlds available resources...how viable is that and/or how long can that go on?
You have already stated that you don't care what happens to everyone else...only to you and yours...that is your only concern. It seems to me that you, as smart as you are, have a lot to learn about the world and compassion for it's denizens... But you will never learn as long as you have all the answers.
