RSI Growth Curves: Which Friction Binds First?

DeepMind's exponential/hyperbolic/S-curve growth shapes are Anthropic's compounding-efficiency/full-RSI/stalled futures seen from the dynamics side, not the policy side — one trichotomy described twice. Both labs converge on the same answer to 'which friction binds first': the slowest un-acceleratable step coupling the loop to reality (verification/oversight at org scale today, physical-experiment and institutional latency at the frontier), not cognition, which is racing and hasn't bent; data-wall and research-gets-harder demote themselves into compute, the abstraction barrier is the candidate fundamental blocker, and deliberate slowdown is the only friction humans must install.
