This problem and the proposed solution involves new ideas and changes across the boundaries of that layers of abstraction, so it would be hard to digest in a single sitting. Unless of course all this was synthesized in your own head :)
My guess is you would need need a more agile version of the Douglas Engelbart's "Mother Of All Demos", a functional prototype that shows everything works together in synergy to create more than a sum of the parts.
The best case would be if all the components of the puzzle are independently valuable, like Musk's SpaceX model.
