Mitochondria Funny Quotes

I see a major flip which sets apart the systems which critically depend on some determined substrates, such as mitochondria and stuff, because they are composed of it, and systems for which just about anything will do as a substrate. While the former is a clear necessary dependence on a requisite physical substrate, for the latter the physical substrate is a mere one out of many realizations. There is no requisite 'composed of' part. Of course, substrate is necessary, I am not denying this kind of dependency, but I still see a major difference. One could picture the social system as an imaginary huge spider standing on a few very thin legs, supported by some solid ground, which is, yes, 'composed of' some processes describable by physics, biology, chemistry, etc. But the funny thing about it is that as the spider grows, it becomes less and less dependent on that standing, because as it evolves and develops more and more legs which support the spider on many different things and are barely dependent on a single ground. As a result, since what it hops on is mostly other spiders or their legs, it seems to not depend anymore on its initial ground. The way I observe contemporary social systems, the proportions are already fully flipped: there are spiders, spiders, spiders, legs, legs, legs, and only little 'physical substrate', which, notably, most of the time plastically follows and reorganize according to where the spider wants it to be.
