I really enjoy seeing thought-provoking posts like this on Hacker News. The practical insight is that complex systems have some level of scale where causality experiments yield the most fruit, and that this effect is measurable. The most interesting parts are the two justifications for why this may be true. (1) "the determinism can increase and the degeneracy can decrease at the higher scale (the causal relationships can be stronger)" (2) "Higher-scale relationships can have more information because they are performing error-correction."
