The passage around this formula

The compute ledger has a plausible, if unproven, path downward. CSAEC_{\mathrm{SAE}} ≈\approx 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…
