Of course, with more opportinities for change there come greater issues of intelligent choice and responsibility. Self-modification is already a part of the mainstream culture. People not just tolerate changes of their knowledge, interests, careers, relationships, clothes, homes, etc. We seek these changes and value them in others. Most of our aspirations and effort are already directed at self-transformation .
Pastoral idylls are no longer our dream, they seem boring.
We want rich life, full of change and adventures. It doesn't bother anybody that our interests change so dramatically within our lifetime that we look more like a chain of different personalities than a single one, with a thread of development connecting these multiple identities. Unfortunately, our abilities to find new interesting things and adapt to them are limited by both the abilities of our biological organisms and the primitive state of the existing technology. So far, people have been using every opportunity to facilitate and speed up change. On the way, we may leave our current interests, homes, bodies and identities, split into parts and reunite with parts of others.
