Possibilities for Future Ray-Tracing?

[Mxyl V]

Having seen some of NVIDIA's latest capabilities, I was wondering (certainly not now, but maybe in several years' time) whether a ray-tracing option could be possible for Dolphin. I'd come across a post from 2014 where an administrator said that ray-tracing, along with SSAO and other options, required changes to the game engine to the point where creating a new game would take less effort; however, modern versions of Ishiiruka (which I understand is distinct from Dolphin) include an option for SSAO, so I'm wondering if anything's changed in that regard that would (hypothetically) make ray-tracing a future possibility.
