Q: Are you optimistic about the future of humanity?
A: I think it depends on the size of the groups we organize ourselves into. I find we are far more imaginative and fearful than we are capable of organizing ourselves. I am hopeful that in the future, technology will help humanity reorganize into peaceful, sustainable groups the size of small villages. We won’t need centralization as a strategy for safety and resources, so we may well trend away from cities. I’m not sure I’m optimistic that this future will emerge without pain, but I’m optimistic that it could happen given what we’ve achieved through our knowledge, innovation and mastery of the material world.
