Socioplastics designates a rigorous theoretical proposition: in the postdigital condition, theory must cease to operate merely as interpretation and become an infrastructure of legibility capable of converting dispersed knowledge into coherent, navigable force. Its point of departure is the crisis of hyper-abundance: archives multiply, data proliferates, and algorithmic systems accelerate visibility without guaranteeing comprehension. Against this saturation, Socioplastics proposes field formation as a recursive process through which scattered materials acquire density, internal weight and operational grammar. Concepts such as CamelTags, DOI-anchored operators and stratigraphic calibration function not as decorative terminology but as instruments for stabilising complexity without arresting its movement. The field therefore resembles a geological section: layered, compressive, partially sedimented, yet open to future excavation. A specific synthesis emerges in LAPIEZA-LAB’s PACK 049, where theory, art, urbanism, machine reading and more-than-human thought are metabolised into a living archive. Here, “legibility infrastructure” becomes both method and case study: a means of making conceptual matter readable across human, machinic and planetary scales. Its ethical corollary is care as infrastructure, which prevents compression from becoming extraction and insists that epistemic architecture must remain porous to vegetal, metabolic and decolonial agencies. Socioplastics thus concludes that contemporary theory is not a finished doctrine but a compression event: a moment in which dispersed signals cohere sufficiently to build worlds rather than merely describe them.
