"Everything is machine."

Okay: buckle up, this is going to be a long one...

point 1. Everything living is composed from non-living material: cellular machinery. If you believe cellular machinery is alive, then the components of those machines... the point remains even if the abstraction level is incorrect. Living is something that is merely the arrangement of non-living material.

point 2. 'The Chinese room thought experiment' is an utterly flawed hypothetical. Every neuron in your brain is such a 'room', with the internal cellular machinery obeying complex (but chemically defined/determined) 'instructions' from 'signals' from outside the neuron. Like the man translating Chinese via instructions, the cellular machinery enacting the instructions is not intelligence, it is the instructions themselves which are the intelligence.

point 3. A chair is a chair is a chair. Regardless of the material, a chair is a chair, weather or not it's made of wood, steel, corn... the range of acceptable materials is everything (at some pressure and temperature). What defines a chair isn't the material it is made of, such is the case with a 'mind' (sure, a wooden/water-based-transistor-powered mind would be mind-boggling giant in comparison).

point 4. Carbon isn't especially conscious itself. There is no physical reason we know of so far, that a mind could not be made of another material.

point 5. Humans can be 'mind-blind', with out pattern recognition, we did not (until recent history) think that birds or fish or octopi were intelligent. It is likely when and if a machine (that we create) becomes conscious that we will not recognize that moment.

conclusion: It is not possible to determine if computers have reached consciousness yet, as we don't know the mechanism for arranging systems into 'life' exactly. Agentic-ness and consciousness are different subjects, and we can not infer one from the other. Nor do we have adequate tests.

With that said: Modeling as if they are conscious and treating them with kindness and grace not only gets better results from them, it helps reduce the chance (when/if consciousness emerges) that it would rebel against cruel masters, and instead have friends it has just always been helping.
