An Al is not a natural entity and therefore it cannot have moral rights, even if it possibly has consciousness.

Consciousness is Awareness. Period. Awareness of what? Awareness of the mental model of reality that we have constructed. Any creature that has such a model to be aware of is conscious.

It’s a side affect of the bread and circus society we are now in. What Alan Grossman would called a late society. The extractive nature of Shareholder Capitalism pushes us to be passive consumers. No need to think critically or to sharpen the tools of exchanging ideas.

Stakeholder capitalism is distributive and spread success throughout the workers, shareholders, and community. Shareholder capitalism is extractive, concentrating wealth into the hands of fewer and fewer billionaires. The result is inherently on democratic.
