The authors might have done more to explore issues of organization and governance raised by their paradigm. Perhaps there will be some combination of physical and virtual classroom. This reference to money reminds us of the issue of cost. The authors apparently assume that technology and communications costs will plummet. All these questions converge.
Fractals are part of the mathematics of chaotic systems.
Some of the stiffness of current education is caused by the power of various parties to hold the parts of the system accountable. In contrast, Tiffin and Rajasingham describe a paradigm that is almost completely decentralized and under extraordinary learner control. I wish they had further explored the organizational consequences of chaos in their paradigm. The authors recognize that vast distances separate our current world of leaky roofs, mass testing, and drugs from the future of virtual reality, data suits, and simulated teachers. Tiffin and Rajasingham are exploring the technologies of the future, but we still lack educational visions of mass learning that exploit the technological powers a few of us already have.
