ML's convergent discoveries — gradient computation, weight sharing, gradient flow solutions, each independently found across disconnected fields — would rescue the field's theoretical foundations by grounding reliability proofs in mathematical necessity rather than fragile generalization bounds, if classical generalization theory were rebuilt rather than merely overturned.

Justifications

SL — Convergent independent discovery establishes that ML's core mechanisms are mathematical necessities (not contingent inventions), which is exactly the depth of grounding needed for reliable foundations — but this rescue path requires a replacement generalization theory, which the overthrow of the classical U-shaped framework has not yet produced

Antecedents (all must be IN):

IN convergent-discovery-reveals-mathematical-necessity — Three of deep learning's foundational mechanisms — gradient computation (backprop independently discovered across fields), gradient flow solutions (residual connections and LSTM gating converging independently), and weight sharing (appearing independently across architectures) — were all independently discovered or converged upon, suggesting these are mathematical necessities of the problem structure rather than contingent design choices.
IN no-reliable-ml-foundation-exists — ML lacks a reliable foundation at either the practical or theoretical level — classical and deep methods have complementary failure modes that prevent either from serving as a complete solution, while the theoretical framework that should guide choosing between them is itself undergoing fundamental revision, leaving both practical deployment and theoretical guidance in a weakened state that may require hybrid approaches.

Unless (any of these IN defeats this justification):

IN classical-generalization-theory-overturned — Classical generalization theory — the U-shaped bias-variance tradeoff — has been overturned by two empirical phenomena: double descent shows test error decreasing again far past the interpolation threshold, and benign overfitting shows perfect training fit coexisting with good generalization in overparameterized regimes.

Dependents

These beliefs depend on this one:

OUT conditional-exits-share-common-precondition — All three identifiable conditional exits from ML's crisis — external economic forcing to redirect evolution, two-cultures unification to dissolve the accountability gap, and rebuilding generalization theory on mathematical necessities — would each independently make the crisis tractable, but all three presuppose overcoming the same foundational obstacle, suggesting that the crisis has a single deep lock rather than three independent ones.
