But the why of it emerging has no tether to it's component parts is not certain and still likely not a waste of time to study even if true such research gets us no further in that specific direction. The stack yields something that is a mystery of how it can do so - as long as it's a mystery, studying in all directions seems warranted. They may be right in that the community has blind spots, but to outright call it as "the wrong direction", doesn't appear their argumentation is convincing, but I concede this is just an annotate of a likely bigger work/thought, so maybe their entire treatise has legs.
