Yo! This is what I'm talkin' about! Replace directories with self-consistent neural nwots [neural blackbox thingie of weights and activation vals]. It's cool, but for every convenience we take in the direction HD space we backpeddle in processing [meaning, although the dir structure could be super condensed this way with a learned index, this approach is less flexible to cold or not-cpu-related analysis]. It's very cool actually to consider the three branches of processing, hdd, and memcache ... You want to have a balance but in the ideal computer we do no calculation, and that is something worth mentioning.
Reading again of the abstract, allow me to add that it's an optimization beyond structures such as Btrees which are already not really decipherable datasets to the naked eyes. So any optimization in a space that's not designed to be human-legible can take whatever shape, and this is certainly a welcome achievement!
