He doesn't address any of the complaints.
I like the guy, and how he made his way out of a dead-end existence. His alternative view of graphics has merit and he deserved a break. He doesn't answer any of the vital questions though, and he shows a fair bit of ignorance that's gone from quaint naivety to being somewhat embarassing. LOD = level of distance? And the examples Notch gave weren't explicit but about voxel data, yet Bruce just says, "we're not doing that (raytracing etc.)," without recognising the complaint. The subject of storage is raised and Bruce answers saying they have no problem with storage, but then they are using only a handful of objects, all regularly placed. There's nothing to indicate his sorting and search method will scale up suitably quickly. There's nothing mentioned about decent animation when a few basic wobbly objects are shown. There's nothing said about shaders and lighting except "that's coming". I have serious doubts he'll be able to pull it off. Basically the tech is a nice, rudimentary graphics demo, like the SAARCor detail demos, not bothering with any of the essentials required for a game. We need facial animation, dynamic lighting, physics interactions, and huge variety of content, none of which are a good match for compressed databases of points. Without showcasing any of that, or saying anything more than, "yeah, it's coming, trust us," I can't see any reason to believe in this tech. It's a spacial sorting algorithm on compresssed data, he's confirmed, fetching one datapoint per pixel (how's he going to deal with AA other than post or supersampling?), which isn't new, yet with his head in the sands Bruce believes it is.
