Agreed. I think much of the western received wisdom on animal cognition actually comes from religious attitudes of the unique specialness of man and his God-given dominion over the birds and beasts.
In general I think we are still adjusting to what science tells us about who "we" are.
For example, we know we're animals. As animals, we experience a concept of "self." So why would we assume that no other animals experience a concept of self?
We know that the mind arises from the brain. So why would we make a distinction between our concept of self and the "other" parts of the brain? The title of the above article is essentially clickbait, in my opinion. There is no scientific basis for distinguishing between the brain and the self.
