Yes, that’s true, and our current system of “corporated capitalism” leveraging means of control of information like patents, intellectual property, digital rights management, copyrights, trade secrets, and so on, is an obvious sign that we haven’t reached system D, yet.
It does, but that’s not relevant, since all things being equal, decentralized organization methods are often more efficient than centralized control structures. That’s why the natural development is towards decentralized structures becoming more important. That we don’t see much of that happening, yet, is merely due to the fact that the transition towards system D is still in a relatively early stage. Things should look much different in the 2030s.
Instead of capitalist social democratic states, we are already ending up with failed states in many regions. The degenerate centralized states of the future will be the failed state scenarios. In the long run, they won’t be able to compete with the rest of the world.
Theoretically, that could happen. Where centralization spreads the dissemination of knowledge, it can be put into use for a positive transformation.
