"AI is built on the collective knowledge of humankind."
No. Nononononono. It is not built on _knowledge_, it it built on _data_. And not everyone's experiences are available as data, many communities are excluded. Also: "Collective" implies some sort of collaboration and shared activity. But "AI" is just accumulation by a few powerful.
So No. It's not collective but extractive, not knowledge but data, not humankind but the hegemonic western view. Everything in that statement is wrong.
