The author seems to believe that REYES-type rasterization algorithms are still the state of the art, but these days everybody does physically-based raytracing (thank $deity, so much simpler!). This may or may not be a useful optimization for SDFs, but SDFs themselves are kinda useless -- not able to show detail well and not practical to model with.
