IMHO the ultimate source of instability is that we deal with pure thought-stuff that has very little internal constraint except at the interfaces. Other engineering is quickly constrained by materials, biology and physics but for us, any idle thought can become our reality. The faster we can communicate and the faster we can build, the faster the iteration.
We can achieve much the same ends in any number of different styles and paradigms. The primitives for a programmer have more to do with poetry, memes, fashion and the creative end of pure math than physical systems. There can be no assumption of convergence. The pull of a social group will crush the technical excellence of an out group.
