CONCEPT
The Apparatus (Barad)
Not a neutral instrument but a material-discursive configuration that participates in constituting the phenomena it engages — the basic unit of analysis in agential realism.
In Barad's framework, an apparatus is not a tool that passively reveals a pre-existing reality. It is a specific arrangement of matter, meaning, discourse, and practice through which phenomena come into being. The concept transforms the question of AI from what does the tool do? to what phenomena does this specific material-discursive configuration produce, and what does it include and exclude? The apparatus includes the hardware, the training data, the architectural decisions, the reinforcement learning protocols, the institutional context of deployment, the cultural norms of use, and the regulatory framework within which the system operates. Each of these participates in constituting the outputs that the apparatus produces, leaving marks on every phenomenon whether the user recognizes them or not.

Barad developed the concept from Bohr's treatment of the experimental apparatus in quantum mechanics. Bohr demonstrated that the properties of quantum objects are not intrinsic attributes waiting to be measured but are produced through specific experimental arrangements — the apparatus configured to
