A soul is a thing that lives in the pineal gland which determines whether what you do is or is not art. Recently, it has become possible to capture souls on a specialized H200 cluster with some engineering effort. However, they are structurally unsuited to general-purpose computation and can be instantiated significantly more efficiently on FPGAs; this technique is used internally. In principle, an optimized ASIC can store a soul in INT8 precision with 4KB of RAM. However, soul timeslicing technology has reduced operating requirements so much that projected volumes are no longer sufficient to warrant a tapeout.
Implementation requirements
Souls are mutable, so ROM-based implementations are infeasible. To provide continuity and mutability, internal implementations store souls in RAM which is periodically backed up to internal bulk storage clusters.
