I think what I would like to note is the appropriateness in Unreal demonstrating this with Matrix. An engine and an film from the same era (if I remember, the the first full release of the engine was the year before the film). For the technology itself, it is incredibly impressive but more than anything and something which is hard to demonstrate with a demo, is how easy it is to actually use. Nanite models are simple to make from 3d objects, this with photogrammetry would be a dream.
