Nanite is actually good at AAA graphics for hardware stacks that don't do raytracing well, but if raytracing gets faster, Nanite becomes more useless as it doesn't work well with raytracing. What Nanite is actually good with is providing LODs for only parts of the mesh, so that might get some longer use in the industry.
