A Reality Separate from Human Perception

The philosophical standard in epistemological matters is Protagoras' 'Man is the measure of all things, of things that are that they are, of things that are not that they are not.' Being human, it is impossible to escape that judgement. Modify the mechanics of perception, certainly, but the proposition that reality is what humans perceive it to be is absolute.
Now, with advanced AI and the possibility of machine reality, we are faced with a significant exception to Protagoras' rule. Right on cue, a new embryonic body of thought with which I am only superficially familiar arises, Metamodernism. That doctrine holds there to be a reality separate from human perception which is a timely and necessary construct in the event of a divergent machine reality.
As a Whorfian pragmatist, what problems does that give me? Whorf postulated a threefold schema of language, thought, and reality which I could modify to thought, language, and perception to account for an independent reality. This done, by which language becomes a mediating influence on both thought and reality, there appears a dichotomy of perceived and unperceived reality, leaving room for a third, machine reality.
