If we think of model, view, controller, much of the complexity seems to be when these dimensions leak into each other. Keeping them orthogonal seems the first

If we think of model, view, controller, much of the complexity seems to be when these dimensions leak into each other. Keeping them orthogonal seems the first step in the process of trading the problem for a smaller problem. As TFA notes, there is a lower limit to how much complexity can be squeezed out of a system.
