Autopoiesis can be ascribed to anything, as long as you're willing to expand the circle sufficiently to include things that all combined can seem self-sustaining. But unless we're talking about perpetual motion machines, eventually something from outside is gonna have to come in.

Affordances I can't comment on. I just googled it. It reminds me of my [theory of use](https://steemit.com/philosophy/@alexander.alexis/what-s-the-use) somewhat. 

Heidegger has some interesting thoughts that again remind me of some of my own ideas that I called the theory of use. I haven't read him much, and what I have read I hardly understand! He also sometimes strikes me as maybe a bit of a con artist of sorts! I mean the kind of things Schopenhauer used to say against Hegel. Mazes of words made to impress but that carry little meaning. I remember when I read his Introduction to Metaphysics, every single translation from Greek was utterly wrong! Like sometimes there wasn't a word in common! Calling it an idiosyncratic translation doesn't begin to describe what he did! It was basically his own thoughts! Highly weird! But I see value in him and I'd like to read more of him in the future.

Thanks for the comment and for reading )
