Very well written! I have to say, I'm siding with Plato on this one.

Very nice post.

However, I'd just like to push back against one point:

'There is a larger cosmic significance to it though. If we zoom out from our anthropocentric view, intelligence is the only force capable of resisting the universe’s inevitable slide toward heat death, where entropy dominates (at least temporarily). Through its capacity to generate extropy, intelligence acts as a counterforce to the natural decay of the cosmos, playing a critical role as the engine that pushes back against entropic collapse.'

I'm not sure (at least straightforwardly) this is Land's view; extropy is not a force against the the universe's inevitable slide towards heat death, where entropy dominates, but rather an efficient mediator of entropy. It's not a counterforce: but a major component of that force. This is seen if you clue into your phrasing 'at least temporarily'. But we're talking about time itself here: how can time be temporarily anything? unless, of course, these extropic processes are a part of time: local order extropy used to increase overall entropy. I believe in a podcast (though I can't be bothered to find which one now) Land points this out: that large, intelligent, extropic systems are actually often *more* efficient at creating entropy; they are efficient exporters of entropy. As you say (much more succinctly and clearly than I ever could) that 'Cybernetics, through feedback loops, enables systems to adapt their behaviour via inputs, outputs, and trial and error, allowing them to evolve and resist decay.' But the decay here is the wearing away of the system whose system flows inputs to outputs. The systems that survive are the ones that can efficiently flow energy from inputs to outputs. Intelligence, therefore, is not a counter-force to the destruction of the universe, but instead the ability to efficiently export to bring about this destruction. Sure, there is local extropy within that system, but that system's goal is to efficiently export entropy.
