The quality of ray traced scenes is much better and much closer to the real world than rasterized scenes. Yet ray tracing is very expensive in terms of computation (often too expensive for real time ray tracing). So we have some technology which delivers superb results but is some sort of 'future technology' as we can't afford it yet. I think that is whats makes so many interested in ray tracing here. We know that some day that technology will revolutionize the rendering industry and every time some progress is presented we are curious how that progress is being made.
