When is enough enough? You can look at it in the negative way, and when humans get together viewing society in this way, evolution turns into revolution, and society is transformed as a result.
We all want a better life, but it is up to us to decide where we want to go. I may be able to tell my 88 year old mother about the various new developments in science and technology, but I can never force her to see the world as I do (nor would I want to). She simply is not a transhumanist or nerdy engineer.
I love life to be more and moore, I did not claim the moorelife domain for nothing. But I also love the present for the present it is! I know gratitude is the driving force that brings new experiences into my life, and that is enough!
