We humans have proven terrible at determining what is sentient. That's why we're still discussing the hard problem of consciousness.

There is the Integrated Information Theory that attempts to resolve how to determine which systems are conscious, but it's far from being the only perspective, or immediately applicable.

From the point of view of one the IIT's main theorists, Christof Koch, we're still far away from machine sentience.

But I question whether if it's so far out to believe a machine capable of not only learning, but learning on their own behavior, self-monitoring for sensibleness and other very 'human' metrics is that far away from being self-aware. In fact the model seems to have been trained exactly for that.
