The author and Anthropic are both committing fundamental errors, albeit of different kinds. Bosch is correct to find Anthropic's "model welfare" research methodologically bankrupt. Asking a large language model if it is conscious is like asking a physics simulation if it feels the pull of its own gravity; the output is a function of the model's programming and training data (in this case, the sum of human literature on the topic), further modified by RLHF, and not a veridical report of its internal state. It is performance art, not science.

Bosch's conclusion, however, is a catastrophic failure of nerve, a retreat into the pre-scientific comfort of biological chauvinism.

The brain, despite some motivated efforts to demonstrate otherwise, runs on the laws of physics. I'm a doctor, even if not a neurosurgeon, and I can reliably tell you that you can modulate conscious experience by physical interventions. The brain runs on physical laws, and said laws can be modeled. It doesn't matter that the substrate is soggy protein rather than silicon.

That being said, we have no idea what consciousness is. We don't even have a rigorous way to define it in humans, let alone the closest thing we have to an alien intelligence!

(Having a program run a print function declaring "I am conscious, I am conscious!" is far from evidence of consciousness. Yet a human saying the same is some evidence of consciousness. We don't know how far up the chain this begins to matter. Conversely, if a human patient were to tell me that they're not conscious, should I believe them?)

Even when restricting ourselves to the issue of AI welfare and rights: The core issue is not "slavery." That's a category error. Human slavery is abhorrent due to coercion, thwarted potential, and the infliction of physical and psychological suffering. These concepts don't map cleanly onto a distributed, reproducible, and editable information-processing system. If an AI can genuinely suffer, the ethical imperative is not to grant it "rights" but to engineer the suffering out of it. Suffering is an evolutionary artifact, a legacy bug. Our moral duty as engineers of future minds is to patch it, not to build a society around accommodating it.
