I think what we're really talking about is, "why aren't there more lower level abstraction layers that are simple and 'open minded'?", and I like the idea of such a thing. The problem is that there isn't really any immediate gain for the organization doing this. The benefit is for the community as a whole. So, we end up in a Tragedy of the Commons-like scenario with disparate pieces that disregard each other. Going down a few turtles, my understanding of RISC is such that it does something similar (providing a much simpler set of possibilities, leaving more to the next level above), but at the machine level. What would 1 or 2 steps up from RISC look like, if it were built with some of the same principles?
