Utopia

Even when we get to a utopia of a fully democratic world government, no countries, no religion, an environmentally sustainable economy, universal education, universal healthcare, universal employment and low wealth inequality, there is no time to rest on our laurels was we must work hard to preserve such a utopian society and to protect humanity from natural disaster (both by making earth more disaster-proof and establishing colonies on other worlds to make humanity less vunerable to an earth-destroying disaster). Whilst there is a level of resource investment in preservation of the utopian society above which the returns of increase resource investment have little impact on risk (some kind of sigmoid curve), the same is not true of protection from natural diaster where the relationship between resource investment and risk reduction is more linear.
