I think adaptive economic planning via cybernetics is just a bit of a curiosity of history. There's been some resurgence of interest in the concept more recently, especially as an inspiration for a more self-regulative economy that is cognizant of its outputs (without resorting to static input-output calculations) - but don't mistake that more recent interest for a sort of general awareness of the idea. Also, even if AES states were aware of the possibilities (as some were around the time Chile tried it, Castro famously visited Allende and advised him to arm the workers) it's not trivial to implement. I'm not even talking about the technological infrastructure needed, even just socially, this is a proper hard project to actually pull off.

Organizational/Management-Cybernetics is a (very cool) niche within the arcanely dusty niche that is Cybernetics - if it is that, and not just a dead proto-meta-science that became IT and all sorts of other disciplines. I'm honestly more surprised to hear more and more people taking an interest in Cybersyn/Cybernetics than I am that nobody implemented it since Chile - the whole topical complex has just been buried under so much history since the coup.
