The concept for circuits of extended phenotype was initially inspired by J. Lovelocks and L. Margulis Gaia theory of bio-geological evolution, that proposes an extended view upon organisms, and their influence on the environment, embracing the nearly infinite reciprocities, between earth and it’s inhabitants. I found Gaian perspective upon organisms as an inspiring leap-point to rethink electronic sound circuit design towards one that could interact with biotic and abiotic environment in it’s full functionality. Through this post-humanist viewpoint for electronics, I invite to rethink the material boundaries of electronic devices, think of how we address the ever growing nature/techne divide, and how sound and listening can become a bridging medium.
