I've seen them. They are nice and very alluring. So are a lot of false things. :) And I should note that I am mainly asserting this as false so that I can further explore the idea.
The idea to generate a new word that is hard to blur from existing ones and depends entirely on context is amusing in this context.
That is, what separates complicated from complex is one of context. Yet... contexts change. And often the first thing you do when building a solution to a problem is to reduce the problem to something easier to solve.
In this angle, I fully agree. Simplify your problem as much as you can. But do not be misled into thinking you can keep it simplified. As you add in more and more of the realities of the problem, they will reflect in the solution. And, often, the worst thing you can do is to try and cling to the "simple" solution that solved a different problem.
That is, understand the simple things well. See how they map onto the complicated things. Don't cling to the idea that they can be merely composed into the complicated solution. Often, several simple solutions can be subsumed by a more complicated one. Much in the same way that higher math can subsume lower maths.
