Given the advent of ultra-powerful technology (fusion power with nanotechnology) the crucial problem before us today is the fostering of good character.
Religious folk (the ones who are doing it right in my estimation) understand this as the continual obligation and joy of remembering God and living in a goodly fashion. Atheists, agnostics, and non-religious but spiritual folk can understand that only wise and good people can be trusted with such tremendous physical power.
We must discover and use whatever means we can to foster good character and wisdom.
