IIRC, there is a bit more complexity than that to the Pirahã understanding of numeracy. Relative quantity is something they’re just fine at understanding, (with words for single/less, plural/more and same) it’s abstraction of quantities to tokenized values where they struggle. Which, I suppose, also interestingly lines up with the study results; the initial training period resulted in nodes associated with quantity, but those nodes were separate/unrelated to numeracy systems that developed with additional training.
Always a little annoyed at articles like this; “strength” doesn’t tell me anything. If this is 5x more resistant than steel to deformation, but then shatters catastrophically, that limits its use cases substantially. Likewise, compressive, tensile and shear strength are all different properties, only one of which is referenced at all. Still very cool, and I look forward to seeing how it develops and learning more details about its capabilities (when I have more time I’ll read the paper), but vague terminology like this has a bad habit of making stuff sound way more revolutionary than it actually is. /shurg
