What happened: Philosopher–psychiatrist Chandra Sripada (Michigan), with a companion paper co-authored with cognitive scientist Rick Lewis, argued that LLMs are "cognitive cousins" rather than alien intelligence: convergence at the level of core processing principles, not outputs. The evidence is mechanism-grade — documented cognitive-science signatures reproduced (garden paths, serial-list memory effects, conjunctive-search slowdowns); the dual-process distinction mapped to in-weights vs in-context processing, with Stroop-family congruency effects reproduced on a small un-tuned model; transformers as independently reinvented production systems; brain-alignment results strengthening with model capability, explained via contravariance (hard problems narrow the solution space).
Diagnostic reading: the strongest evidence yet assembled at the cognition pressure point (FND-01 v2.1 §4.2) — the "just autocomplete" disqualifier engaged mechanistically and found wanting — and, equally, the corpus's clearest case of symmetry practised: the same standards run both directions ("You say that LLMs are a black box. The mind-brain's a black box"), with the sample-efficiency embarrassment volunteered against his own thesis. Note what is not claimed: the consciousness inference is stated in explicitly conditional form — if functionalist about consciousness, then moved toward attribution — the framework dependency marked rather than smuggled, in instructive contrast to the direct attribution documented in the Hinton entry. Host Sean Carroll supplies a Thread 1 datum of his own: "I'm actually on the side of the goalpost movers" — criteria revision declared openly, then credence following evidence through the revised criterion (FWK-03 v1.3 §1.2.1's first self-aware refinement instance). The contravariance explanation cuts symmetrically: convergence-under-constraint disciplines over-reading of machine–brain convergence exactly as it disciplines over-reading of convergence elsewhere.
