Nice for avant garde architecture and if you want to put modern artists out of work.

 I suspect people who take to this are the same birds of a feather as those who fiddles with 2D and 3D fractals and the like. But appart from this, I don't see the relevance to the tris vs quads topic. All examples, in its finished form, could just as well be made with quads. Compare with modeling with nurbs. Nurbs also allows you some amazing and powerful modelling but in the end, it must be converted to quads. If you are going to sell your model that is. All of us who live by selling 3D mesh must compel by this rules or die. The customer demands it.
