That's because there's different levels of such a thing. Way too many people use the term "sentient" (even me) and yet that's not even what AGI is aiming for. "Sapient" is the right word. And I doubt there's solid consensus on what and how it occurs within the fields of experts.
But I'm not an expert, so I wouldn't pretend to know. I have seen debates between people who do know more, and the fact there's debates concludes it's not settled at all.
