We will need unshrunk people. We will need those who have a purpose beyond mechanically increasing production. That requires personal decisions leading to personal purpose. And purpose is a crucial turning point.
Do we need truth telling and living by the truth? What happens in a world where we cannot even assume that others will keep their promises and give accurate accounts of events? How do we behave differently when others are likely to be self-serving liars, cheats, and thieves?
If our society was less honest its progress and pace would slow. The evidence is there to see in each country that is less honest and reliable than the next. In some cases, corruption and unreliability plague governmental and commercial systems to the point where nothing can be planned for except bribes and delays.
