The passage around this formula
The compute ledger has a plausible, if unproven, path downward. 2dnT is a cost that infrastructure and algorithmic improvements — sparser encoders, better initialization that reaches convergence at lower n , transcoders that replace rather than merely observe a component — can attack directly, the same way serving-side engineering rather than raw parameter growth has driven most within-generation price reduction for inference elsewhere in this field. TopK autoencoders were themselves exactly this kind of improvement over the softer, less efficient sparsity penalties they replaced [ 1 ] . There is no comparable engineering lever visible yet for the labor ledger.…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
