Philosophies, morals, that sort of thing. Some just believe we are shutting our self in too much as a race because of technology. In a way sadly, it is true. Not many connections left to nature save for the farmers that provide most if not all of our food.
Even though it is true that we should not destroy our world in the process of advancement, I would very much rather be "disconnected" from nature rather than having to fight for my food and life every day. The main goal of life is to survive and reproduce, and technology is the best way for the human race to achieve that.
