As a trained economist I understand the deflationary tendencies of revolutionary technology. In the near future we will likely face a combination of two economically earthshaking technologies. The first will be abundant and cheap energy, through solar, fusion, and other emerging technologies. The second will be the advent of Generalized Artificial Intelligence. Both of these technologies will undoubtedly create a recipe of strong deflationary tendencies within the economy of the world.
As far as my noetic faculties can reach, this will lead to something fiat economies are most endangered by. Namely, deflation. Mind you, even a small percentage of deflation will cause the super-rich to lose their minds.
Keynesian economics will most likely be on steroids due to this, and will be ineffective no matter how much money gets injected into the economy.
Is there anyway to prepare for this eventuality?
