> An objective and grounded ethical framework that applies to all agents should be a top priority.

I mean leaving aside the problem of computability, representability, comparability of values, or the fact that agency exists in opposition (virus vs human, gazelle vs lion) and even a higher order framework to resolve those oppositions is a form of another agency in itself with its own implicit privileged vantage point, why does it sound to me that focusing on agency in itself is just another way of pushing protestant work ethic? What happens to non-teleological, non-productive existence for example?

The critique of anthropocentrism often risks smuggling in misanthropy whether intended or not; humans will still exist, their claims will count, and they cannot be reduced to mere agency - unless you are their line manager. Anyone who wants to shave that down has to present stronger arguments than centricity. In addition to proving that they can be anything other than anthropocentric - even if done through machines as their extensions - any person who claims to have access to the seat of objectivity sounds like a medieval templar shouting "deus vult" on their favorite proposition.
