Ray-tracing as it currently stands will never dominate computer graphics, because it is essentially brute force. Progress is being made in reconstructing a scene out of a very noisy, low sampling rate [1], which is a much better indication of the future direction of raytracing, where a series of advanced prediction and reconstruction algorithms are used to efficiently render scenes, rather than simply throwing more hardware at the problem.
